The destruction of lithium iron phosphate battery packs for electric vehicles includes the following aspects：
1. The battery maintenance board is damaged, and the above electronic components are intensive and difficult to repair.；
2. The battery maintenance board is intact, and the function of a single battery is even worse, and it is not easy to find.;
3. The battery maintenance board is intact, and individual batteries should be checked for short circuits.
In short, after the failure of the lithium iron phosphate battery of an electric vehicle, it is usually difficult to repair after the failure, and the technical personnel of the lithium iron phosphate battery manufacturer will solve it, or replace the lithium iron phosphate battery pack of the same type of electric vehicle.
Repair the battery with an electric vehicle battery charger: the charging voltage, current, and model and specifications of the electric vehicle battery of the electric vehicle charger match.Therefore, car chargers cannot repair battery packs, and may use higher-power electric vehicle chargers.
Example: 1. The specification of the electric vehicle battery pack is 48V20AH, which can be charged and repaired with a 60V20AH battery charger; 2. The 48V12AH battery pack can be charged and repaired with a 48V20AH battery charger.
Maintenance principle: The important reason for the failure of the battery function is that the battery has been vulcanized, and the battery manufacturer's after-sales maintenance of the battery.All kinds of battery repair instruments and repairers on the market use high-power charging equipment to remove vulcanization and repair batteries with high current and high voltage.Therefore, individual chargers with power supplies have the function of removing sulfur from the battery.
