Analysis of the maintenance and precautions of lithium-ion battery electric vehicles

1. It is forbidden to lose power. Idle batteries are strictly prohibited from being in a power loss state when they are stored. The state of power loss means that the battery is not charged in time after use. When the battery is stored under the power-deficient state, sulfation is easy to occur, and the lead sulfate crystals adhere to the electrode plate, which will block the electric ion channel, resulting in insufficient charging and a decrease in battery capacity. The longer the idle time in the power-deficient state, the more severe the battery damage. Therefore, when the battery is not in use, it should be recharged once a month to better maintain the battery health. 2. Regular inspections. During use, if the continued mileage of the electric vehicle suddenly drops more than ten kilometers in a short period of time, it is very likely that there is a problem with one of the batteries in the battery pack. At this time, you should go to the sales center or agent maintenance department for inspection or grouping in time. This can relatively extend the life of the battery pack and save your expenses to a large extent. 3. Preventing high-current discharge When electric vehicles start, carry people, or go uphill, try to prevent violent stepping and acceleration, resulting in instantaneous high-current discharge. High-current discharge can easily lead to the appearance of lead sulfate crystals, thereby damaging the physical properties of the battery plates. 4. Correctly grasp the charging time. During use, you should accurately grasp the charging time according to the actual situation, refer to the usual frequency of use and mileage, and grasp the frequency of charging. During normal driving, if the electricity meter indicates that the red and yellow lights are on, it should be charged; if only the red light is left on, stop running and charge as soon as possible, otherwise the battery will be over-discharged and its life will be seriously shortened. After fully charged, the running time is short, and the charging time should not be too long, otherwise it will cause overcharging and make the battery heat up. Overcharge, overdischarge and undercharge will shorten the battery life. In general, the average charging time of the battery is about 10 hours. If the battery temperature exceeds 65°C during the charging process, stop charging. 5. Prevent exposure to the sun. It is strictly forbidden to expose electric vehicles to the sun. An excessively high temperature environment will increase the internal pressure of the battery and cause the battery to lose water, cause the battery activity to decrease, and accelerate the aging of the electrode plate. 6. Prevention of plug heating during charging. 220V power plug or charger output plug loose, contact surface oxidation, etc. will cause plug heating. Excessive heating time will cause plug short circuit or poor contact, damage the charger and battery, and bring you loss. Therefore, when the above situation is discovered, the oxide should be cleaned up or the connector should be replaced in time. Seven, the cleaning of electric vehicles The cleaning of electric vehicles should be carried out in accordance with normal car washing methods. During the cleaning process, attention should be paid to prevent water from flowing into the charging socket of the vehicle body and prevent short circuit of the body line. In the following cases, it will cause the paint layer to peel off or cause corrosion of the body and parts, and the vehicle must be cleaned immediately. --When driving along the coast; --When driving on a road sprinkled with antifreeze; --When it is stained with grease and other sundries; --When driving in an area where the air contains a lot of dust, iron filings or chemical substances When the electric vehicle is manually cleaned in a cool place, wait until the body temperature drops below 40 degrees Celsius, and then clean it. - Use a hose to wash away loose dirt; - Use a neutral car washing agent to clean the vehicle. The cleaning agent should be mixed according to the manufacturer's instructions. Use a soft cloth soaked in the cleaning fluid, and do not rub hard to avoid damage to the paint 8. Frequently check the tire pressure to keep the tire pressure at the correct tire pressure; check the tire pressure every two weeks or at least every month; incorrect tire pressure will cause power consumption, short driving distance, and reduce driving comfort. Reduce tire life and reduce driving safety; Statement: Some pictures and content of articles published on this site are from the Internet, if there is any infringement, please contact to delete the previous article: Battery cycle life and precautions for use
