1. Used Fuel Car oil maintenance The maintenance cycle of Used Fuel Car oil mainly depends on the type of Used Fuel Car oil used. Generally, mineral oil is changed every 5000km, semi-synthetic oil is changed every 7500km, and fully synthetic oil is changed every 10000km. 2. The air filter is the same as the air conditioning filter. It is basically changed every 15000km, but the regulations of each car dealer are different. In fact, I think the most reliable way is to check it every time and change it if it is dirty. 3. The fuel filter is generally changed every 30000km, and there are differences between different car dealers. I personally think that a slightly longer time will not have much impact, but I want to tell you something dry. Note-The Spring Festival is coming soon, and many people have to drive back to the countryside for the New Year. Try not to go to those small gas stations to refuel. Some unscrupulous merchants have done something wrong. After refueling, the car will vomit and have diarrhea, and a series of problems such as engine fault lights, shaking, and refueling powerlessness will appear. 4. Maintenance of brake fluid. Generally, it is changed every 2 years and 40,000 km. How to say this? Many car owners will say that I have not changed it for five or six years. There is no problem. Why waste money to change it? The editor wants to say that because brake fluid is water-absorbent, the brakes will become soft over time, the braking distance will become longer, and it is very uncomfortable to drive. There are many specific ways, which will be explained in the future, so I will not go into details here. 5. Maintenance of spark plugs

When the rear windshield is blocked, you will lose part of your rear view when driving on the road or reversing, which greatly reduces driving safety. Therefore, the rear Used Car wipers are equally important. The rear Used Car wipers of this model have three gear adjustments, namely slow, medium and fast. When encountering foreign objects blocking the view, the Used Fuel Car wipers should be sprayed forward or backward before the Used Car wipers work, so that the friction resistance of the entire Used Fuel Car wiper movement process can be reduced. So as to achieve the purpose of extending the life of Used Car wiper blades and preventing the glass from being scratched by foreign objects. Wiper blades are consumables. One-time purchase does not guarantee a lifetime benefit, so the service life of Used Car wipers should be extended through correct operation. Many people will ask, how long should Used Car wipers be replaced? Generally speaking, they should be replaced in one to two years. But our suggestion is: the effect of Used Car wipers is significantly reduced after hanging, so they should be replaced. And developing good usage habits can also help reduce scratches on the front windshield, so why not?

When charging a new Electric Car for the first time, it is not necessary to discharge the electricity before charging. Lead-acid batteries have no memory effect. It is generally recommended to charge the battery pack when the remaining capacity is 30% to 40%. It is generally not recommended to exceed 12 hours. In theory, the smaller the charging current, the better. Because the current is small, the smaller the crystals generated by the reaction, the more complete the reaction, and the more electricity can be stored. Moreover, the smaller the current, the smaller the heat of the battery, the less likely the plate is to deform, and it will not cause the effective material on the plate to fall off. The dedicated smart charger uses decay current charging, that is, a larger current is used at the beginning of charging. As the battery voltage rises, the charging current automatically decreases until the voltage reaches about 13V and the charging stops automatically. On rainy days, New Car should be parked in a place sheltered from the rain for charging, because water is a conductor. If you charge an Electric Car in the rain, you may get an electric shock; when charging an Electric Car, you should also pay attention to the positive and negative poles of the charger. If the positive and negative poles are reversed, the battery may be damaged. Therefore, strict attention is required in this regard.

Electric Car use electric motors instead of fuel engines and are driven by electric motors without the need for automatic transmissions. Compared with automatic transmissions, motors have simple structures, mature technologies, and reliable operation. Traditional internal combustion engines can limit the speed when efficiently generating torque to a narrow range, which is why traditional internal combustion engine vehicles require large and complex transmission mechanisms; while electric motors can efficiently generate torque in a fairly wide speed range, and do not require gear shifting and transmission devices during the driving of New Car. They are easy to operate and have low noise. Compared with hybrid vehicles, Electric Car use a single source of electricity, and the electronic control system greatly reduces the internal mechanical transmission system of the vehicle, has a simpler structure, and also reduces the energy loss and noise caused by the friction of mechanical parts, saving space and weight inside the vehicle. The motor drive control system is the main executive structure of Electric Car during driving. The drive motor and its control system are one of the core components of Electric Car (battery, motor, electronic control). Its driving characteristics determine the main performance indicators of vehicle driving, and it is an important component of Electric Car. The three major categories of Electric Car, fuel cell vehicles (FCVs), hybrid Electric Car (HEVs) and Electric Car (EVs), all use electric motors to drive the wheels. Choosing a suitable electric motor is an important factor in improving the cost-effectiveness of various Electric Car. Therefore, it is

1. Difference in service life The service life of the battery is the most concerned point for consumers when purchasing. At present, the average service life of lead-acid batteries is about 2 years, and the number of cycles is between 300 and 500 times; the average service life of graphene batteries is about 3 years; lithium batteries have a longer service life, with a cycle number between 700 and 1000 times, and the battery can be replaced every 4 years. In the past two years, the spontaneous combustion caused by Used Car batteries is mainly caused by Used Electric Car equipped with lithium batteries, especially many small workshops that privately make lithium batteries. Because the density of lithium batteries is large and the heat resistance is poor, if it is overheated, such as in summer or charging for too long, exceeding the load temperature, it may cause spontaneous combustion, especially inferior lithium batteries should be more cautious in safety. Lead-acid batteries are relatively stable and generally rarely spontaneously combust. 2. Difference in safety performance Degree, it may cause spontaneous combustion, especially inferior lithium batteries should be more cautious in safety. Lead-acid batteries are relatively stable and generally rarely spontaneously combust. 3. Warranty difference The warranty period of Used Car batteries is an important standard that car owners can refer to when exchanging for other batteries. The warranty periods of lead-acid batteries, graphene batteries, and lithium batteries are very different. Generally, lithium batteries have the longest warranty period. 4. Battery maintenance tips Plug in

When going to work in the morning, you often see many elderly people or parents driving Used Car to send students to school, but this kind of Used Electric Car often fails. Let us learn about the common faults of Used Car. The noise of Used Car is a common problem. The main reasons are large bearing clearance in the motor, motor rotor sweeping, loose and falling magnets, axial movement inside the motor, oxidation, ablation, oil pollution, uneven surface of the brush motor commutator, and loose commutator segments. The failure of the instrument panel to display is also a common fault of Used Car. The main reason for the failure is that there is no voltage between the positive and negative leads of the instrument, the wire or connector is short-circuited, or the instrument is damaged. If the Used Electric Car is powered on, the wheels will turn, and the incremental speed is very fast. This fault is called flying car, which is mostly caused by the poor contact cycle of the ground wire of the turn handle, or it may be a controller failure. The out-of-control horn of the Used Electric Car is mostly caused by damage to the horn, damage to the switch, or short circuit of the connecting wire or connector. These aspects are mainly checked during maintenance.

1. Use the original optional charger when charging, otherwise it will easily affect the life of the power battery or even cause damage. 2. Please use the specified lubricant. 3. Please slow down and drive carefully on rainy days or on roads with water accumulation. If the motor system is damaged by water due to wading, it will not enjoy the quality assurance service. If you treat it well, it will treat you well. Just pay a little attention to these matters that must be paid attention to, which can help you use Used Car better and keep your Used Car as good as new. 4. Please do not change the structure of Used Car or add accessories other than the plateau design (such as adding leaf springs, adding electrical equipment, etc.) without authorization, otherwise the faults caused by them will not enjoy the quality assurance service. 5. Used Car are prohibited from overloading and speeding. Try to avoid sudden braking, as well as emergency braking when driving at high speed. Please pay attention to ensure that the tire pressure is within the specified value range. 6. When driving, avoid sudden starting and sudden acceleration to prevent safety accidents. The charger must use original accessories, otherwise it is very likely to cause the Used Electric Car to fail to work properly. 7. When the Used Electric Car actually travels 2000-2500km, mandatory maintenance must be carried out, and then three routine maintenance must be carried out every 1000km.

Used Car are energy-saving and environmentally friendly, safe and reliable, low-cost, comfortable and flexible, and have many advantages, such as no pollution and low noise. Compared with internal combustion engine vehicles, Used Car do not produce emission pollutants when working, and the noise generated by the drive motor when working is also less than that generated by the internal combustion engine. Used Car have high energy efficiency, and their energy utilization efficiency has exceeded that of gasoline engine vehicles, especially when running in the city, the car stops and starts, and the driving speed is not high, Used Car are more suitable. Used Car do not consume electricity when they stop. During the braking process, the motor can also be automatically converted into a generator to realize the recycling of energy during deceleration braking. Used Electric Car have a simple structure and are easy to use and maintain. Used Car have a simpler structure than internal combustion engine vehicles, with fewer operating and transmission parts, and less maintenance work. When using AC induction motors, the motor does not require maintenance, and Used Electric Car are easy to operate.

The battery life has also been greatly improved. The life of lithium-ion batteries in Used Car depends on the charging method. Under normal circumstances, if the battery is fully charged and the vehicle is driven until it is 100% discharged, if it is recharged, the number of cycles is about 1,000; if 50% of the battery power is used and then recharged, the charge and discharge cycle becomes 5,000 times; if everyone charges as they use, the maximum charge and discharge cycle is 8,000 times under normal use. It is said that the current battery life can be used for about 20 years. (1) Battery performance depends on the battery management system Another "key" to determining battery performance is the battery management system (BMS). The BMS is usually designed to be integrated with the battery and is also included in the integrated power control unit (EPCU). It monitors the battery's charge and discharge status, and when the battery detects an abnormality, it automatically connects or disconnects the battery power through a relay (a device that opens and closes other circuits in certain circumstances). It also allows the battery management to reduce performance at low temperatures. (2) The drive motor achieves self-charging Another major component of an Used Electric Car is the "motor". It is actually part of the engine, converting electrical energy into kinetic energy and storing it in the battery. The same is true for deceleration while driving, which is called a regenerative braking system. Currently, some Used Car such as Hyundai, Kia, and General Motors are equipped with devices that can gradually adjust regenerative braking. (3) Speed ​​reducer is equivalent

1. Used Car are energy-saving and environmentally friendly, green and pollution-free. Used Car do not cause pollution during operation, unlike Fuel Car that emit gases such as nitrogen dioxide, which is beneficial to environmental protection. 2. Used Car can also be charged at night when electricity consumption is low, making full use of electricity resources and balancing the quality of power supply in the power grid. On the one hand, it can save costs. In addition, it can also produce good social benefits and obvious environmental benefits. 3. Used Car have a simple structure and are easy to operate and maintain. It is convenient for middle-aged and elderly people to learn, and its speed regulation system can also complete very stable speed regulation, run smoothly, and ensure safe and stable driving. 4. Used Car have a reverse gear driving function. Compared with Used Electric Car, reverse driving can be easily completed, and there are voice prompts, which is very practical in narrow alleys and lanes.

Now more and more people are using Used Electric Car in life. Compared with traditional fuel vehicles, they are more environmentally friendly, so they are more popular. So how many kilometers can an Used Car like this run? Let's give you a brief introduction today. 1. Used Car (BEV) refer to vehicles that use on-board power as power, use motors to drive wheels, and meet the requirements of road traffic and safety regulations. At present, Used Car can run up to about 500 kilometers, and most Used Car can run more than 200 kilometers. 2. After the Used Electric Car is proposed, the power must be replenished in time to keep the battery in a full state. During use, the charging time must be accurately grasped according to the actual situation, and the charging time must be grasped by yourself according to the usual frequency of use and mileage. During normal driving, if the power meter indicates that the red and yellow lights are on, you should go to charge. 3. If only the red light is on, you should stop running and charge as soon as possible. Excessive discharge will shorten the battery life. The charging time should not be too long, otherwise it will form overcharging and make the vehicle battery hot. Overcharging, over-discharging and undercharging will shorten the battery life. During the charging process, if the battery temperature exceeds 65°C, charging should be stopped. 4. The battery must not be placed in a sealed container, close to an open flame, thrown into a fire or immersed in water, and is strictly prohibited from direct exposure to the sun. During the use of Used Car, it is forbidden to step on the accelerator (throttle) hard. T

The increasing popularity of Used Car has made more and more people pay attention to their maintenance issues. Although Used Car have obvious advantages in maintenance compared to traditional fuel vehicles, this does not mean that the importance of maintenance can be ignored. How to properly maintain Used Car is the key to ensuring their long-term and safe operation. So do you know how to maintain Used Car? The maintenance of Used Car is different from that of traditional fuel vehicles. It pays more attention to the maintenance of battery packs, motors and electronic control systems. First of all, the battery pack is the core component of Used Car, and its performance directly affects the vehicle's cruising range and service life. Therefore, regularly checking the health of the battery pack, replacing damaged battery cells, and keeping the battery pack clean and dry are important parts of Used Electric Car maintenance. Secondly, the motor and electronic control system are also key parts of Used Electric Car. The motor is responsible for converting the electrical energy of the battery pack into mechanical energy, while the electronic control system is responsible for regulating the energy conversion between the battery pack and the motor. Regularly checking the operating status of the motor and electronic control system, cleaning related components, and replacing severely worn parts can effectively improve the performance of Used Car and extend their service life. In addition, the regular maintenance items of Used Car cannot be ignored. For example: regularly changing the oil and filter, checking the brake system and suspension system, etc., these maintenance items also apply to Used Car.

1. After picking up a Used Electric Car, it must be recharged in time to keep the battery fully charged. To avoid damaging the battery, over-discharge, under-charging and over-charging are prohibited during use. Charge in time on the day after use, and the longest time shall not exceed 3 days. 2. During the use of Used Electric Car, it is forbidden to step on the accelerator (throttle) hard. The speed should be increased slowly, otherwise it will seriously affect the battery life and even burn out the motor. 3. In daily use, Used Electric Car should try not to drive to the maximum mileage. The best mileage is 1/3-2/3 of the longest mileage. (For example, for a car with a maximum mileage of 150km, it is best not to exceed 100km in daily use, which can greatly extend the battery life and reduce the cost of battery use.) 4. When the Used Car is not in use, the battery needs to be fully charged and stored, and recharged once a month to avoid long-term power loss and lead to sulfation of the battery plate. 5. The charger used with the vehicle must have sufficient accuracy and voltage and current stabilization performance and pass the company's technical inspection and certification. It is strictly forbidden to use chargers with poor quality, low price and poor aging resistance, otherwise it will damage the battery. 6. The battery must not be placed in a sealed container, near an open flame, thrown into a fire or immersed in water, and must not be exposed to direct sunlight. 7. Gel batteries are acidic solutions. If they get on your skin or clothes, rinse them with clean water immediately. 8. The ambient temperature during charging should be between 10℃-30℃, and g

Due to the continuous tightening of my country's policy on the purchase of gasoline vehicles, choosing Used Car is the general direction of consumers who have not yet bought a car, because Used Car are supported by policies. In addition, Used Car are usually equipped with relatively High-end technological hardware configuration is indeed a good choice. On the other hand, people living in small third- and fourth-tier cities have a love-hate attitude towards Used Car. Used Electric Car are subsidized when purchasing, and maintenance is effortless, and battery charging is not troublesome. Although long-distance travel and battery life are a headache, the more deadly problem is the attenuation coefficient of Used Car batteries. At the same time, this is also a problem that all potential customers are afraid of. The attenuation coefficient of rechargeable batteries is regular. Used Car battery packs are often considered to be very fragile and easy to attenuate. This is not the case. The ternary lithium battery is a very regular and rule-based type of lithium battery, as long as it is used properly, the attenuation coefficient rate can achieve very good control. In order to ensure the rights and interests of consumer groups, our country has long established perfect standards for Used Car rechargeable batteries, mandating that the car battery pack must have a warranty period of 8 to 12 years. During this period, if the rechargeable battery has a decay coefficient rate More than 20%, replacement or repair costs are borne by the manufacturer. With the protection of international standards, consumer groups do not have to worry about economic losses due to the attenuation coefficient of the batter

My country's auto industry is going through a period of adjustment. Under the trend of declining passenger car sales, the industry is seeking new market growth. In the downturn in the auto market in the first half of the year, Used Electric Car market has risen against the trend. The scale in the next few years will increase. expand further. However, due to the large reduction in subsidies this year, the growth rate of the Benben E-star market has shown a sharp slowdown in the past two months. Although the Benben E-star has developed rapidly in the past few years, the current product price/performance ratio is still difficult to match. Compared with fuel vehicles, Used Car are mainly sold in cities with limited traffic and purchase restrictions. my country's Chang'an Used Car market is facing huge external challenges, mainly reflected in market competition and corporate system strength. my country's Chang'an Used Car industry has a certain first-mover advantage, but in recent years, the electrification trend has become the development consensus of the global automobile industry , has begun to vigorously enter the Used Car market in my country. These brands have accumulated a certain amount of brand appeal through years of car manufacturing technology and technology, which will bring challenges to my country's car companies. In addition, there is also the problem of insufficient internal power. At present, the technical economy of Used Car in my country is not completely comparable to that of traditional fuel vehicles, and there is also a certain gap with international advanced Used Car. The performance of power batteries still cannot fully meet the demand. Some key com

After the winter, many online hailing drivers of Used Car felt that the battery life of the vehicles was lower than before, and the batteries did not seem to be particularly durable. Therefore, someone asked the editor in the background that it was not something wrong with his car. Otherwise, there are many factors that affect the continuous voyage and charging time of Used Electric Car in winter. Most of the power batteries currently on the market are lithium batteries. For lithium batteries, low temperature will affect the activity of the positive and negative electrode materials of the battery, the internal resistance of the battery, and the charge and discharge voltage of the battery. In other words, the lower the temperature, the lower the activity of the electrode material, the less the lithium ions in the electrolyte move, and the higher the energy driving their movement. In this case, the appearance is that the battery capacity is low. up. However, this reduction in capacity is temporary, and it can return to normal when the temperature rises and the discharge conditions improve. 2. Related to driving habits When driving in winter, try to drive at a constant speed to maintain the health of the battery. Especially when starting or going uphill with people, it is recommended that drivers try to avoid slamming on the accelerator, which will cause high current discharge. Moreover, if the brake utilization rate is too high, a large part of the energy will be wasted by braking. For the Used Electric Car with energy recovery function, the higher the energy recovery function is set, the stronger the deceleration effect of the vehicle. The decelerating effect causes

At present, the world's energy and environmental systems are facing great challenges. As a major player in oil demand and carbon dioxide emissions, vehicles need to undergo subversive transformation. At present, the development of new energy electric vehicles in the world has established a consensus. In the long run, Used Electric Car promotion including pure Used Car and hydrogen fuel cell technology will be the actual technical direction of Used Car. In the short term, Gasoline-electric hybrid power and electrified hybrid power will be crucial connecting lines. The production, supply and sales of Used Car in my country continue to grow.  With the continuous improvement of the three electric technologies, more and more application scenarios are beginning to try to use Used Car, from the initial use of new energy technologies for small and light vehicles in the urban freight logistics industry, to gradually expanding to A large number of application scenarios, such as the new energy technology of large vehicles such as environmental sanitation industry, municipal construction freight logistics industry, seaport transportation industry and mining transportation industry, have been recognized for the development prospects of Used Car, especially the prevalence of battery replacement methods , Bringing a broader application scenario to the new energy technology of large vehicles, Used Car products are also more colorful and complete. The development trend of Used Electric Car is based on various factors that affect the development of the Used Car industry, and summarizes the characteristics of the overall operation and development trend of the Used Electric Car industry in the future. It combines the advanta

From the perspective of the global development of Used Car, its power sources mainly include lithium-ion batteries, nickel-metal hydride batteries, fuel cells, lead-acid batteries, and capacitors, among which capacitors are mostly in the form of auxiliary power sources. The main reason is that these battery technologies are not fully mature or have obvious defects. Compared with traditional cars, there are many gaps in cost, power and cruising range. This is also an important reason for restricting the development of Used Electric Car. Lead-acid battery: Lead-acid battery has a history of more than 100 years and is widely used as a starting power source for internal combustion engine cars. It is also a mature Used Electric Car battery, which has good reliability, easy-to-obtain raw materials, and low price; the specific power can basically meet the power requirements of Used Electric Car. But it has two major disadvantages; one is that the specific energy is low, and the mass and volume occupied are too large, so the mileage of a single charge is short; the other is that the service life is short and the cost of use is too high. Ni-MH batteries: Ni-MH batteries are alkaline batteries. Ni-MH batteries have a long cycle life and high energy density, but they are expensive and have memory effects. The foreign company that produces Used Electric Car Ni-MH batteries is mainly a joint venture between Ovonie, Toyota and Panasonic. Ovonie currently has two unit batteries of 80A·h and 130A·h, with a specific energy of 75-80W·h/kg and a cycle life of more than 600 times. This kind of battery is used in several Used Electric Car vehicles, one of which can travel 345 kilometers on a single charge, and one

The value chain of the Used Car industry is being innovated, the traditional rules of the game are being challenged, broken and rebuilt, and it is shifting from product competition to service competition, from single-link competition to business model system comprehensive capability competition, and from intra-industry competition to cross-industry competition. Used Car are facing enormous pressure to survive. The decline of subsidies, overcapacity and the influx of new car manufacturers are intensifying competition. From the perspective of its own profitability, on the one hand, costs are rising; on the other hand, the profit model has yet to be reconstructed, and there is great uncertainty in new profit sources. Therefore, how to deal with challenges and break through is a must-solve problem for Used Electric Car companies. 1. Used Car and fuel cell vehicles will jointly dominate the development of China's Used Car market. Pure electric models will be the mainstream products in the passenger car market, and hybrid models are just a transition. Fuel cell vehicles will be developed first in the field of commercial vehicles, and it will be difficult to promote them to the passenger vehicle market in the short term. 2. Intelligence, networking, and humanization will become the core competitiveness of products, and users will no longer worry about battery life and charging convenience. With the continuous development of battery technology and the continuous improvement of energy density, it is an inevitable trend to increase the cruising range of Used Electric Car. In addition, a survey of consumers found that 60% of high-end car owners and 89% of low-end car owners believe that U

The reason why Used Car are called elderly scooters also vividly reflects the main aspects of current needs. Two big changes, one is that living standards have improved, this is a fact; the importance of Used Car can be realized. One is that today's society has entered an aging society, and this is also the current situation. Nowadays, people`s living radius has become larger and cities have become larger, so short-distance travel has become a necessity for the elderly. Shopping for groceries, medical treatment, and even transporting grandchildren to and from school are likely to be these common daily tasks. Application, the elderly scooter just fills the gap in this short-distance travel tool. Therefore, the market is developing rapidly. In addition, it is difficult for many people to get a driver's license, and Used Electric Car do not require a driver's license due to the delay in the introduction of standards. Therefore, the market is a bit strange, but that is the current status quo. Everyone will get old, so reasonably solving the problem of short-distance travel for the elderly is something that today's society needs to jointly deal with. We cannot blame the elderly alone, nor is it purely a problem of the management department. It is true that Used Electric Car are involved in a wide range of things. If you want to do a good job Not a very simple matter.
