Analyze the repair method of electric vehicle lithium battery pack

Repair methods for electric vehicle lithium battery packs 1. Regrouping: After the entire battery pack is damaged, we often perform charge and discharge tests on electric vehicle lithium battery packs. During the inspection, it is often found that 50% of the batteries in a set of batteries are unbalanced. No damage. 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: Replenish the battery that has been used for about 4 months in the lithium battery pack of electric vehicles, which can extend 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: Take the particle generator in parallel with the battery to repair the lithium battery pack. This method is better for repairing lithium batteries in 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 in electric vehicles. 5. Comprehensive repair methods for lithium battery packs for electric vehicles: regular inspections are adopted for lithium battery packs for electric vehicles, desulfurization and water replenishment are carried out in time, and single batteries are charged and reconfigured. 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.
