Lithium batteries of electric vehicles are generally composed of at least ten or more lithium batteries connected in series, with a built-in battery protection board, which is completely different from lead-acid batteries . packs (the quantity is small and there is usually no protective panel). If a fault occurs, non-professional technicians usually cannot resolve it.
Damage to electric vehicle lithium batteries generally includes the following situations:
1. The battery protection panel is damaged. The electronic components in it are densely packed and generally. difficult to repair.
2. The battery protection panel is intact. If the performance of individual batteries deteriorates, it is not easy to find it.
3. The battery protection panel is in good condition. Ifsome batteries are short circuited, please check it.

How to repair lithium batteries for electric vehicles:
Reconfiguration:
Once the assembly battery is damaged, We often carry out charge and discharge tests on lithium batteries for electric vehicles. During inspection, it is often found that 50% of the batteries in a battery bank are not damaged. The reason is that in a series connected battery, the individual batteries lag behind, leading to a drop in performance of the entire battery, which leads to a drop in performance of the entire battery.
Hydration:
Replenishing water to electric vehicle lithium batteries that have been used for approximately 4 months can extend battery life to an average of more than 3 months. It should be noted that afterWhenever water is refilled, the battery is in an overcharge state to convert the battery from a "near-liquid-poor" state to a "liquid-poor" state, and this overcharge is beneficial to increase the battery capacity . .
