Now, with the country's continuous promotion of
Used Electric Car and news reports that some European countries have announced that they will suspend the sales of
fuel vehicles around 2035, more and more car owners choose Used
Electric Car as their second car for their families. However, as a new thing, many people don't know how to maintain
Used Car. In fact, when it comes to maintenance, Used Electric Car mainly do a good job in battery maintenance.
① How to charge
During normal driving, if the meter shows red and yellow lights on, it should be charged. If only the red light is on, stop the operation and charge the battery as soon as possible, otherwise the over-discharge of the battery will seriously shorten its service life. The charging time should not be too long, otherwise it will cause overcharging and make the battery overheat. Overcharging, overdischarging, and undercharging will shorten battery life. Generally, the average charging time of the battery is about 8-10 hours. The ambient temperature range for vehicle charging is 0C-45C. When the ambient temperature is lower than 0°C or higher than 45°C, please do not charge the vehicle.
② How to maintain the battery
One is that deep discharge needs to be carried out regularly, about once every 2 months, which is conducive to activating the characteristics of the battery, and can also slightly increase the capacity of the battery, which is very beneficial to the battery. Second, charge it every day. Most chargers are actually about 97%~99% charged after the indicator light is fully charged. Although a power difference of 1% to 3% has little effect on battery life, it will constitute an undercharged battery pack. So when the battery light shows full, let it charge for as long as possible. Charging the battery every day can keep the battery in a shallow cycle state, which is beneficial to prolong the service life of the battery.
In addition, when we charge or maintain the battery, we should strictly refer to the battery operating instructions. We cannot charge the battery or modify the charging device with a non-matching charging cable without permission. After 2-3 months of normal operation, the battery should be properly maintained and various functions of the battery pack should be tested.
③What should the car do if it is not used for a long time?
Batteries don't have to be slowly discharged for long periods of time until they fail. Therefore, the car should be started every once in a while to charge the battery. If you find it bothersome, remove the two electrode wires from the battery. All you need to do at this point is remove the positive and negative leads from the poles. First remove the negative wire or the connection between the negative pole and the chassis of the car, then pull out the other end with the positive symbol.
The battery has a certain service life and must be replaced after a certain period of use. When replacing, the above sequence should be followed, and when connecting the electrode lead, the sequence is just the opposite, first connect the positive pole, then connect the negative pole.
④Prevent large current discharge
Used Car should try their best to prevent the accelerator from accelerating under pressure when starting, carrying people and going uphill. Lead sulfate crystallization will occur during instantaneous high-current discharge, thereby damaging the physical function of the battery board.
5. What are the symptoms of battery problems?
If the mileage of the Used Electric Car suddenly drops by more than ten kilometers in a short period of time, it is likely that at least one battery in the battery pack has a problem. At this time, please check, repair or assemble in the 4S mall in time. This prolongs the life of the battery pack, maximizing your savings.
Of course, we ourselves should also pay attention to cultivating car habits to prevent problems before they happen. Good driving habits are also a kind of maintenance and life extension of the battery. In addition, we should also pay attention to the dry and ventilated charging environment, avoid heavy rain and sunlight, let the battery run or charge in a good environment, and reasonably control the charging time.
In general, we should carefully understand the functions of Used Electric Car, especially the functions of the battery, clearly grasp the charging time and maintenance date, and do a good job in order to prolong the service life of the battery and realize the real green travel!
