During the use of Used Electric Car, in order to ensure the normal operation of Used Electric Car, it is necessary to carry out daily maintenance on Used Electric Car. Routine maintenance is an important part of giving full play to the efficiency of Used Car, reducing driving accidents, saving maintenance costs, reducing energy consumption and prolonging the service life of Used Car. It is what every driver needs to do before and during driving. The main content as follows: 1. Before driving in the rainy season, you must first do a pre-driving inspection, mainly to check whether the wiper and the defogging function of the Used Electric Car air conditioner are normal. 2. In general, the driving speed in rainy days should not exceed 60KM/H. In case of heavy rain, try not to drive. If driving, the speed should not exceed 20KM/H. 3. When the Used Electric Car breaks down and cannot be driven during the rainy season, it should pull over and wait for the tripod to be rescued, and self-repair is prohibited. 4. When driving on a muddy road, do not slam on the accelerator or brake pedal to avoid sideslip. 5. Please do not drive into deep water to avoid short leakage circuit accidents. 6. When the Used Electric Car is soaked in stagnant water, it is not allowed to continue driving. The power should be cut off quickly and leave the vehicle. Try not to contact the metal of the vehicle body to avoid electric shock. ① Check the fastening of main components such as steering, brake, suspension and transmission. ② Check the vacuum pipe for air leakage. ③ Check whether there is oil leakage in the drive axle main reducer, steering mechanism and va

In daily life, Used Electric Car are our main means of transportation. We often use Used Electric Car, and there will be a lot of dust and dirt on Used Electric Car. How should we clean and maintain our Used Electric Car? The editor has summarized a few points for everyone, hoping to help you. 1. When our Used Electric Car are covered with dust, we should scrub them frequently. When we scrub Used Electric Car, we should not splash water on them. Because there are many circuits in Used Electric Car, if the circuits are wet, it will affect the use of Used Electric Car. It may damage Used Electric Car. 2. When we clean Used Electric Car, we should use a rag to wring it half dry and then scrub the Used Electric Car slowly. We can first use a wet rag to wring it dry and scrub the whole body of the Used Car. Change a few basins of water for the dirtier places, and be patient and scrub slowly.

Don't replace the charger of Used Electric Car casually, and don't remove the speed limit of the controller. Chargers of various manufacturers generally have personalized requirements. Don't replace the charger casually when you are not sure. If the control computer board requires a long range, it must be equipped with multiple chargers for charging in different places. The charger that is charged during the day should be used with another supplementary charger, and the original charger should be used at night. Although removing the speed limit of the controller can increase the speed of some vehicles, it will not only reduce the safety of the vehicle, but also reduce the service life of the battery. Generally, there are instructions on protecting the charger in the instruction manual. Many users do not have the habit of reading the manual. They only think of looking for the manual after some simple problems occur, so it is very necessary to read the manual first. In order to reduce costs, chargers are basically not designed to withstand high vibration, so chargers are generally not placed in the trunk and basket of electric bicycles. In special circumstances, it is necessary to move, and the charger needs to be packed with foam plastic to prevent vibration and bumps. Even if your range requirement is not long and you can use it for 2 to 3 days after charging once, it is still recommended that you charge it every day, so that the battery is in a shallow cycle state and the battery life will be extended. The sulfidation process begins after the battery is discharged. After 12 hours, obvious sulfidation appears. Timely charging can prevent serious sulfidation. If it is not charged in time, these sulfi

In fact, every time before or during operation, you must ensure observation, testing, and listening. Observation means carefully observing whether every important component on the car is damaged. Testing means completing multiple test starts to detect whether the car's control system is normal. Then listen. Of course, it means carefully monitoring whether there are abnormal sounds when the vehicle is started or running. For example, if the noise is too loud, it can be judged whether the motor and rear axle are in good condition. When you suddenly find that the battery life of an Used Electric Car has dropped to a great extent while running, and it can only travel for more than ten kilometers, it is very likely that there is a problem with a battery in the battery pack of the Used Electric Car. In such a situation, you should find after-sales service to complete the inspection in time to prevent failures at the critical moment of operation. In the operation link of the battery, it is found that the charging time of the battery has been extended a lot. This is probably caused by battery aging. You can find a technician to complete the inspection. Hereby remind some consumers that the number of deep charging and discharging of Used Car batteries is limited. In the operation link, the charging time should be mastered according to the operation situation. Excessive charging, discharging and insufficient charging will reduce the battery life. When an Used Electric Car is not used for a long time, it is best to charge it once a month. The battery should be fully charged before storage. Used Car should never be stored when the battery is low.

To put it simply, the external circulation of Used Electric Car is to get the air inside the car outside, and then replenish the fresh air outside into the car. The internal circulation of the car is to prevent the outside air from entering the car, and only use the existing air in the car for circulation, so that there is no need to heat the cold air outside the car. In winter, when the temperature difference between the inside and outside of the car is relatively large, the internal circulation of the car is obviously more conducive to heat preservation. Experiments have confirmed that if the internal circulation of the car is used during damage, the cruising mileage of the car can be minimized to a great extent. Under the same test conditions, the cruising mileage of the experimental car can be reduced from 50% to about 15% under relatively poor conditions. If the blower blows less air, it will also reduce external consumption. In addition, the good insulation, good workmanship, and small gaps of the Used Car itself can also help. In winter, not only do air conditioning and seat heating consume a lot of energy, but cold weather also affects the performance of the battery. In order to ensure the stability of Used Electric Car in terms of mileage and driving force, behaviors that consume a lot of energy such as sudden acceleration and high-speed driving should be actively avoided. At the same time, it is also necessary to make use of the power acquisition system of the car as much as possible to help the car acquire more energy by reducing the number of times the Used Car brakes are pressed.

An Used Electric Car is a car powered by electricity. It is usually powered by a high-speed rechargeable battery or a fuel cell. Do you know how to charge an Used Electric Car? Let's take a look at the charging methods of Used Car. Battery charging equipment is one of the indispensable subsystems of Used Car. It converts the power of the power grid into the power of the on-board battery of Used Car. There are different ways to classify Used Electric Car charging equipment, which can be generally divided into on-board charging devices and non-on-board charging devices. Used Car can be charged by the traditional charging method of constant voltage and constant current. Just plug the plug of the on-board charger into the power socket in the parking lot or at home to charge. It can be directly powered by the low-voltage lighting circuit. The charging power is small and is powered by a standard grid power supply with a specification of 220V/16A. Used Car should not be charged with fast charging as much as possible. Using fast charging will accelerate the attenuation of the vehicle battery pack. In the fast charging state, high power and high current charging will indeed cause certain irreversible attenuation to the battery pack. Long-term use of fast charging will cause damage to the battery of the Used Electric Car. Therefore, everyone needs to charge slowly with a suitable charging power.

Used Electric Car refer to vehicles that use onboard power as power, use motors to drive wheels, and meet the requirements of road traffic and safety regulations. Let's take a look at the maintenance and care methods of Used Electric Car. Used Car maintenance requires checking the cleanliness of the charging parking space, whether there are any debris, and whether there are any flammable and explosive objects around. Check whether there are foreign objects on the surface of the charging pile; secondly, check whether the power supply and communication line connection of the charging pile are normal; check whether the fire protection facilities at the charging position meet the relevant regulations and requirements, and check the maintenance records. Maintaining Used Electric Car also requires regular cleaning of dust and dirt on the battery cap, and keeping the battery dry and clean to prevent the battery from discharging itself. The battery should be installed after being removed and charged, and the battery should be fixed on the Used Car to avoid vibration damage during driving. In addition to daily maintenance, Used Electric Car should also be periodically maintained and maintained after driving a certain distance to keep the vehicle in good operating condition. In addition to completing daily maintenance, low-speed Used Electric Car also need to check whether the battery is qualified; whether the insulation resistance of each component of the electrical system meets the specified requirements.

Used Electric Car refer to vehicles that use onboard power as a power source and use motors to drive wheels. Nowadays, Used Electric Car are increasingly used in our lives. Used Electric Car use electric motors instead of fuel engines, which are low-noise and pollution-free. The space and weight occupied by electric motors, fuel and transmission systems can be used to compensate for the demand for batteries; and Used Car do not have the noise generated by internal combustion engines, and the noise of electric motors is also smaller than that of internal combustion engines. Used Electric Car use electrical energy, and there is no exhaust gas during driving, which does not pollute the environment; because they use a single electrical energy source, they save the engine, transmission, fuel tank, cooling and exhaust system, so the structure is simpler. Used Electric Car are more convenient to drive. At present, Used Car are in one gear, which means that there is almost no need to operate them. The speed of forward movement mainly depends on the strength of your acceleration, so it is more convenient to drive and easier to get started.

1. What to do if the car does not move after being fully charged: When you think that the Used Car has been fully charged, but the car does not move after starting, Solution: Check whether the power indicator is fully charged, and secondly, check whether there is noise during operation. If the noise is very loud, it may be a problem with the motor or the control board. This requires choosing a regular Used Electric Car repair shop WeChat or replacing new parts. 2. Sometimes when driving an Used Car out, you find a "squeak, squeak" noise, how to deal with it Solution: This situation may be caused by a problem with the rear axle of the car. Check whether the rear axle of the car is loose and whether the screws are loose. Then try your best to tighten the rear axle of the car and tighten the screws. 3. What to do if you find that the brakes do not stop when you step on them Solution: In order to reduce costs, some Used Car manufacturers choose low-end Chinese accessories, such as low-end brand brake systems, which are naturally unstable. If you step on the brakes when driving an Used Car, but the car cannot stop, you should not be afraid of danger and immediately turn off the Used Car's power door lock, which is actually the key lock. Of course, this works on flat roads. If it is on a steep slope, the car will run down due to inertia even if it is turned off.

Maintenance of Used Electric Car. Generally, the rain in the city contains acidic substances, and these rainwater will corrode the car paint. Therefore, it is recommended to wash the car in time after the rain. You can also choose maintenance items such as polishing, waxing, coating, sealing glaze, and crystal coating that have a protective effect on the car paint, so as to prevent the damage of acid rain from corroding the car. At the same time, it is recommended to lubricate and dehumidify the door locks, door hinges, etc., and check and replace the wiper blades as appropriate. Maintenance of electrical control system. In rainy seasons, due to the damage of factors such as car wading, rain and high air temperature, it is easy to cause the entire vehicle electrical control system of Used Electric Car to be damp. The entire vehicle circuit should be checked in time, especially the various plugs and exposed electrical equipment component connectors, even the various connectors of high-voltage wiring harnesses, to complete the corresponding dehumidification operation. Maintenance of the chassis system of Used Electric Car. Due to factors such as car wading, the steering, braking and other systems should be checked, and lubrication, dehumidification and rust prevention tasks should be done well. In addition, please pay attention to the waterlogging spots in various districts of Shenzhen and drive safely, especially those car owners who have not purchased water crossing insurance. When driving, you should be more careful to avoid low potholes and be careful to avoid the roads below.

1. Used Electric Car do not have a good solution to environmental problems. Although the country strongly advocates power lithium batteries as the power source of Used Electric Car, due to their relatively high prices, many manufacturers use lead-acid batteries as power in order to obtain higher profits. The service life of lead-acid batteries is about 2-3 years, and the replacement cycle is slightly shorter. The cost of recycling discarded lead-acid batteries is high, and pollutants such as lead and sulfur will be produced. 2. The quality cannot be guaranteed. my country does not have good management regulations for Used Electric Car, and no matter what company, there is a lack of strict quality control work processes, so the quality of many Used Electric Car cannot be guaranteed. When the circuit of the whole vehicle is worn or there is water, a short circuit fault may cause a fire, threatening the life safety of the public. 3. Affecting traffic management. The Used Car sales market is mainly in towns and counties. Most users are elderly people who do not have a driver's license, and most users are not very clear about traffic regulations. They often run rampant when driving Used Electric Car, affecting traffic management. 4. The range is limited and battery charging is inconvenient. Used Electric Car are powered by electricity and generally have a shorter range. Currently, there are not enough charging stations in my country. Once the electricity is exhausted, Used Electric Car will not be able to continue driving, causing a lot of trouble for people.

1. What to do if the car does not move after being fully charged: When you think that the Used Electric Car is fully charged, but the car does not move when it is started. Solution: Check whether the Used Car power indicator is fully charged, and secondly, check whether there is a noise when running. If the noise is loud, it may be a problem with the motor or control board. This requires WeChat or replacement of new parts at a regular Used Electric Car repair shop. 2. Sometimes when driving an Used Car out, you find a "creaking, creaking" noise. Solution: This may be a problem with the rear axle. Check whether the rear axle can fall off and whether the screws can fall off. Then try your best to tighten the rear axle and tighten the screws. 3. If you find that the brake is continuously pressed during braking. Solution: In order to reduce costs, some Used Electric Car manufacturers still choose low- and medium-end accessories from China. For example, the braking system of low- and medium-end brands is naturally unstable. If you step on the brake while driving an Used Electric Car, but the car cannot be stopped, you must remain calm and turn off the electronic lock immediately, which is actually the key. Of course, this is feasible on flat roads. If it is downhill, the Used Electric Car will run down due to inertia after it is turned off. You can only jump out of the car or grab the square plate to adjust the car to a safe and flat road and then turn off the electronic lock.

Compared with hybrid Used Electric Car, Used Car use motors instead of internal combustion engines, which are low-noise and zero-pollution. The space and time weight occupied by motors, fuel and transmission devices can be used to compensate for battery requirements; and because of the use of a single electric energy source, the electronic control system is greatly simplified compared to hybrid Used Electric Car, reducing costs and also compensating for the price of battery parts. Compared with gasoline vehicles, Electric Car are more compact, with fewer operating and mechanical parts and less maintenance. When using AC induction motors, does the motor need maintenance? More importantly, Used Electric Car are easy to operate. At the same time, the energy of the braking system and downhill can be recovered to improve energy utilization; research on Used Electric Car has found that its energy utilization efficiency has exceeded that of gasoline vehicles. Especially in urban operation, vehicles stop and go, and the driving speed is not too high, Used Electric Car are more suitable. Used Electric Car do not consume electricity when they stop. In the braking system, the motor can automatically convert into a generator set to realize energy reuse during braking and deceleration.

1. Regular charging and maintenance Regular charging and maintenance of Used Electric Car can effectively reduce battery damage caused by power loss, and can also improve the performance indicators of the entire new energy vehicle. When not in use for a long time, the battery should be charged and maintained every month. If it is not convenient to fully charge and discharge, you can fully charge it when the power is below 10%, which can also play a certain role. 2. Pay attention to tire pressure When the tires of Used Car are kept at a higher air pressure, it will not only reduce the level of bumps during driving, eliminate the discomfort caused by objects such as stones, but also reduce the friction resistance between the tires and the road surface, so it has the effect of improving the cruising range. 3. Pay attention to the battery operating temperature The battery should be kept at 0-40 degrees Celsius as much as possible. High or low will also affect the battery cell, especially long-term high temperature will cause great harm to the battery cell, and relatively low temperature will also cause a sharp drop in cruising range. 4. Regular maintenance of lubrication standards Although the mechanical system of Used Car is much more streamlined than that of fuel vehicles, better lubrication standards are still a prerequisite for comfortable, environmentally friendly, energy-saving and safe driving.

1. New Car batteries cannot work with electricity. When repairing the charging part and replacing a new charging fuse, the 220V power plug must be unplugged first. Every time you stop, you must turn off the main power switch, pull out the key, turn the gear switch to the neutral position, and pull up the handbrake. 2. When charging, try to avoid contact with children, and try to carry out in areas where children cannot touch. 3. When a fire is caused by an accident or other reasons, the main power switch should be turned off immediately. 4. Since pure Electric Car equipped with lithium batteries are more prone to fire accidents, do not drive recklessly. The situation of reckless driving of battery vehicles is also very serious. 5. When using Electric Car, regularly maintain electrical components to ensure that they are not exposed to water and dust.

(I) Technical level: Although domestic automobile enterprises have responded strongly to the R&D and production of Electric Car, the models with high technology content and mass production are limited, and as the competition of pure Electric Car begins to intensify, the R&D cost is too low and the innovation ability is insufficient, which directly affects the level of New Car technology with independent intellectual property rights in my country; (II) Battery level: "Power supply" is the "technical shortcoming" of the future development of Electric Car. There are currently two major problems: one is that the cost of rechargeable batteries is high, the specific energy of rechargeable batteries is low, and the battery life of Electric Car after charging is short. Will there be a real lithium battery recycling, leasing and re-production industry chain in the future New Car market? Third, the rechargeable battery ports are different, just like the charging ports of mobile phones of different brands are different. The uncertainty of "standards" will have a great impact on the development of battery vehicles, etc. (III) Energy level: The investment in Electric Car is more expensive than that of diesel vehicles. Its application of power engineering requires the construction of power stations, power transmission and distribution equipment, intelligent charging stations, and battery factories.

Pay attention to heat dissipation when charging. Never charge in the sun in summer. All Electric Car batteries should be charged frequently. The charging time should not be too long and should not exceed twelve hours. In addition, the depth of discharge has a great relationship with the life span, that is, how much power is left in your battery. This is also the reason why you charge frequently. When starting, carrying people, and going uphill in New Car, please use the pedals to assist, and try to avoid instantaneous high-current discharge. High-current discharge can easily lead to lead sulfate crystals, thereby damaging the physical properties of the battery plates. It is strictly forbidden to store Electric Car batteries in a low-power state. Low-power state means that the battery is not charged in time after use. When storing batteries in a low-power state, sulfation is likely to occur. Lead sulfate crystals adhere to the plates, blocking the ion channels, causing insufficient charging and a decrease in battery capacity. The longer the battery is idle in a low-power state, the more serious the battery damage. Therefore, when the battery is idle, it should be recharged once a month, which can better maintain the battery in a healthy state. The ambient temperature for charging Electric Car batteries is about 25℃, and it should be kept dry, ventilated, and without direct sunlight. Therefore, it is a very wrong practice for many Electric Car owners to push the vehicle back to the room for charging. It is not only a threat to their own safety, but also not good for the vehicle battery. Many people have the habit of using New Car. They usually wait until the power is off befor

Electric Car are divided into AC Electric Car and DC Electric Car. Electric Car are usually referred to as vehicles that use batteries as energy sources, and convert electrical energy into mechanical energy movement through controllers, motors and other components to control the current size to change the speed. Before work, the brakes, horns (alarms), lights, battery voltage, and current must be checked. If there are any abnormalities, they should be repaired or replaced. It is forbidden to force operation when the machine is not in normal condition. Pay attention to the charging time and resolutely avoid charging for too long. Since a large part of electric bicycles do not have overcharge protection function, continuing to charge the battery after it is fully charged is very likely to cause high temperature of the battery, and such high temperature is also very likely to cause fire accidents. Comply with road traffic safety laws and regulations. When riding an New Car on the road, you must understand the road traffic laws and regulations, and you must not violate the regulations, such as driving in the opposite direction, speeding, or running red lights, and you must not cross the road or change lanes suddenly at will, otherwise it may cause dangerous accidents.

Electric Car are pure Electric Car that are powered by batteries (batteries) and driven by motors (DC, AC, series excitation, external excitation). Let's learn about the service life of Electric Car shared by New Car manufacturers. Battery life, the battery life of Electric Car is affected by many factors, such as manufacturer, battery quality, size, capacity and environment. Under normal circumstances, the battery life of Electric Car is usually 2 to 4 years, and the distance is about the same. The environment in which Electric Car are used is also one of the factors affecting the life. For example, the environment in which the vehicle is parked, the road conditions, the weather environment, etc. are all factors that affect the life of Electric Car. The service life of Electric Car is generally between 3 and 5 years, but if the owner maintains it properly and uses the car gently, it can be extended to 10 years or even longer. In order to protect the battery vehicle, it is necessary to pay attention to daily care and maintenance, such as sun and rain protection, avoid bumpy and rugged roads, and match high-quality chargers.

New Car are more environmentally friendly in daily use and are increasingly popular with the public. But for Electric Car beginners, charging is indeed a skill that needs to be learned and mastered, so how can we charge correctly and reasonably? Let's learn about how long it usually takes to charge an Electric Car from Electric Car manufacturers. Charging time varies depending on the model and power: the charging time of New Car of different models will be different. Generally, we can learn about the charging time through the Electric Car manual or by asking after-sales service personnel. In addition, the power of the Electric Car is also an important factor in determining the charging time. On the premise of ensuring stable charging, the charging time required for an Electric Car when the power is low will be shorter than when the power is full. Charging time is affected by the charger and charging method: the charging time of an Electric Car is also related to factors such as the power of the charger, the environment and temperature during charging. For example, the charging time of an ordinary household socket will be longer than that of a charging station because the charging station has higher power. When charging an Electric Car, the charger will adjust the charging flow and charging voltage by itself. Some chargers that are maintained in time support charging methods such as fast charging, slow charging, and timed charging. At the same time, an uninterrupted and stable circuit environment should be maintained during the charging process to prevent the charging efficiency of New Car from being affected by factors such as circuit overload and current fluctuations. The charging time
