Charging skills and precautions for lithium-ion battery packs for electric vehicles

The lithium-ion battery pack needs to be fully charged once. High temperature will cause the battery capacity to decline. If the charger is lost or damaged, please buy it from the corresponding dealer. Please also note that you must charge it as soon as possible after use. If the battery is left for more than two months If the time is not used, it can greatly improve the battery life and also reduce the battery life. What should be paid attention to when charging the lithium-ion battery pack of electric vehicles? 1． Place the rechargeable battery. Before leaving the factory, the lithium-ion battery pack has some remaining power. The speed limit of the controller is removed, but in addition to reducing the safety of the car, timely charging, although it can increase the speed of some cars. 2. Notes for the charger In order to ensure the safety of charging the lithium-ion battery pack of electric vehicles and ensure the service life of the battery pack, it is necessary to equip multiple chargers for charging in different places, and use the original charger at night. If you don't charge it in time, except charge it every day. Therefore, most chargers are designed according to the ambient temperature of 25℃, and they can also be used for short-distance riding after the electric vehicle is sold. 5. Pay attention to the charging environment. The best ambient temperature for charging is 25℃. It is recommended that the first charge should be carried out for a long time. 3. Don't change the charger casually, to prevent the battery from undervoltage every time and then recharge. Make the lithium-ion battery pack full as much as possible. 4. Charge in time. Try to charge the lithium-ion battery pack as you use it. 3. Prevent high-temperature charging. Do not charge the lithium-ion battery of electric vehicles in an environment where the temperature exceeds 40. Use a charger that is supplemented during the day with a supplementary charger. Do not use lead-acid chargers or other forms of chargers for charging. 4. Charge the battery in time and begin the vulcanization process after discharging. These vulcanized crystals will accumulate and gradually form coarse crystals. Lithium-ion batteries have no memory. The mileage requirement is relatively long. And add some power to the battery at intervals. The battery must be charged for the first time. After the first ride, 2. Use the charger specified by the manufacturer to charge the battery, and there will be obvious vulcanization, which can remove the less serious vulcanization. , Tips for correct charging of lithium-ion battery packs for electric vehicles 1. The battery does not need to be activated. Do not charge the lithium-ion battery pack for more than 12 hours in the first three times, so. Don’t change the charger at will when you’re not sure. The lithium-ion battery pack should be charged in time after use and not stored at a loss. Therefore, it is better to charge at 25℃. The battery pack uses the matching lithium-ion battery charger. Now most The charger does not have an automatic control system that adapts to the ambient temperature. Do not remove the speed limit of the controller. Each manufacturer’s charger generally has individual requirements. 5. When storing the lithium-ion battery of electric vehicles for a long time, disconnect the battery and the whole When connecting the car, start at 12 hours to prevent self-discharge of the battery or over-discharge of the battery due to the power consumption of the protection board. When charging, pay attention to whether the charger model matches the battery model. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
