What are the ways to repair lithium battery packs for electric vehicles

1. Reconfiguration: After the entire battery pack is damaged, we often perform charge and discharge tests on the lithium battery packs of electric vehicles. During the inspection, it is often found that 50% of the batteries in a group of batteries are not damaged. The reason is that in the series-connected battery pack, individual batteries lag behind, resulting in a decline in the function of the entire battery pack, so that the function of the entire battery pack is reduced. 2. Water replenishment: A replenishment of the battery used for the lithium battery of electric vehicles for about 4 months can prolong the service life of the battery and extend the time evenly to more than 3 months. It should be noted that after each refilling, the battery is in an overcharged state to turn the battery from a quasi-lean liquid to a lean-liquid state, and this overcharge is good for improving the battery capacity. 3. Eliminate vulcanization: use battery repair equipment to eliminate vulcanization of the battery. 4. Particle generator: The particle generator is connected in parallel to the battery to repair the battery. This method is better for repairing the lithium battery pack of electric vehicles, but because the repair is relatively thorough, if there is no over-discharge, the possibility of battery vulcanization is often completely eliminated for the continued use of lithium batteries for electric vehicles. 5. Comprehensive repair method: regular inspection of lithium batteries for electric vehicles, timely desulfurization and water replenishment, single battery charging and reconfiguration. The battery description, if it is maintenance-free, generally do not add water. If you want to add water, first test the electrolyte density of the electric vehicle battery itself, and select the corresponding concentration or no concentration of water to supplement according to different situations, so that the battery capacity can be increased or the service life can be extended.
