What problems should be paid attention to when charging lithium-ion battery packs for electric vehicles

Lithium battery packs have some remaining power before they leave the factory, and they can also be used for short-distance riding after electric vehicles are sold. After the first ride, the battery must be charged for the first time. It is recommended that the first charge should be carried out for a long time. The lithium battery pack should be charged in time after use and cannot be stored at a loss. If the battery has not been used for more than two months, The lithium battery pack needs to be fully charged. 2. Notes for the charger In order to ensure the safety of charging the lithium battery pack of electric vehicles and ensure the service life of the battery pack, the battery pack uses the supporting lithium battery charger. If the charger is lost or damaged, please buy it from the corresponding dealer. Do not use lead-acid chargers or other forms of chargers for charging. 3. Don't change the charger casually, don't remove the speed limit of the controller. Each manufacturer's charger generally has individual requirements. Don't change the charger at will when you are not sure. If the continuation mileage requirement is relatively long, it is necessary to equip multiple chargers for charging in different places. The chargers for supplementary charging in the daytime should be supplemented with chargers, and the original chargers should be used at night. Removing the speed limit of the controller can increase the speed of some cars, but in addition to reducing the safety of the car, it will also reduce the service life of the battery. 4. After the rechargeable battery is discharged in time, the vulcanization process begins, and after 12 hours, a distinct vulcanization occurs. Charging in time can remove the less serious vulcanization. If not charging in time, these vulcanized crystals will accumulate and gradually form coarse crystals. Therefore, in addition to daily charging, you must also pay attention to charging as soon as possible after use, and try to use lithium The battery pack is fully charged. 5. Pay attention to the charging environment. The best ambient temperature for charging is 25°C. At present, most chargers do not have an automatic control system that adapts to the ambient temperature, so most chargers are designed according to the ambient temperature of 25°C, so charging at 25°C is better.
