How to repair lithium batteries for electric vehicles?

How to repair the lithium battery of electric vehicle? 1. First judge the working voltage of the lithium battery, usually 48v or 24v. Then find the node of each battery pack to measure whether the single-pass voltage is normal. In general, the single-pass voltage should be the same. If there are different voltages, It proves that there may be a problem with the transfer battery pack. 2. The battery sulfation failure can be repaired with a repairer. By measuring the battery status, positive and negative variable frequency particle waves are continuously emitted during the charging and discharging process. After about 15 hours, the hardened battery can be removed after crystallizing. Lead sulfate. But it should be noted that the repair method of lithium battery for electric vehicles, which is generally only suitable for slight sulfation. If the sulfation is severe, replace the battery with a new one. 3. Battery plate softening failure. After the battery is discharged to 10.5V, use a bulb to discharge it deeply for 1 to 5 hours. Then use the activation instrument to activate the repair. In this way, there is a certain chance that the lithium battery of electric vehicles can be repaired, but if the situation is serious, it can only be replaced with a new one. 4. Multi-string and multi-parallel method: Generally, the low-voltage battery is supplemented in series with a DC power supply, or the load meter is used to reduce the voltage of the high-voltage battery in a series to achieve the effect of battery voltage balance; If the voltage difference is tens of millivolts, the charging or discharging is not easy to operate. If someone is guarding it, it will easily charge up or down. Obviously this method of repair is very inconvenient; the efficiency is also low, and several groups of lithium cannot be repaired in a day. Battery.
