What are the precautions for charging lithium battery packs for electric vehicles?

What should be paid attention to when charging lithium battery packs for electric vehicles? 1. The rechargeable lithium battery pack has a part of the remaining power before leaving the factory, and it can also be used for short-distance riding after the electric vehicle is 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 not stored under power 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. Do not change the charger casually, do not remove the speed limit of the controller. Each manufacturer's chargers generally have individual requirements. Do not change the charger at will when you are not sure. If the continuation mileage 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. The vulcanization process began after the rechargeable battery was discharged in time, and obvious vulcanization appeared after 12 hours. Charging in time can remove non-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 use lithium as much as possible. The battery pack is fully charged.
