How to repair lithium battery circuit if it is broken

1. First determine the working voltage of the lithium-ion battery, which is generally 48V or 24V. The single-transmission voltage should be consistent. If there are different voltages, it means there may be a problem with the battery. . 2. However, it should be noted that the repair method of lithium-ion batteries for electric vehicles is generally only suitable for slight sulfation. If the sulfation is significant, the battery should be replaced with a new one. Relevant Knowledge: 1. Due to the memoryless nature of lithium-ion batteries, the battery must be charged regularly and quickly after each ride or daily if the lithium-ion bike has been left for more than two months. must be recharged. A full recharge. If the battery plate is softened, discharge the battery to 10.5V then use a light bulb to deeply discharge it for 1-5 hours. Then use an activatorto activate and repair. There is some chance that an electric vehicle's lithium-ion battery can be repaired, but if the situation is serious, it can only be replaced with a new one. 2. Multi-series and multi-parallel method: generally, a DC power supply is used to connect low-voltage batteries in series one by one, or a load meter is used to connect high-voltage batteries in series one by one to lower the voltage to achieve the battery voltage balance effect; If the voltage difference is tens of millivolts, charging or discharging is not easy to use, otherwise it will be easy to charge high or low. is very impractical; it is also inefficient and cannot repair multiple sets of lithium batteries in a day.
