Repair method of electric vehicle battery

After a period of use, the battery capacity of electric vehicles will decline. Water loss, imbalance, sulfation and plate softening all affect the battery life. Here are some ways to repair the battery

1. Water loss     It is necessary to replenish water for the electric vehicle battery, which can prolong the service life of the battery. It is suggested to use medical disposable syringe, which is easy to use and measure. The water replenishing tool should not use any metal equipment. The metal needle should be removed from the syringe and a plastic tube should be used.

2. Imbalance     Find out the capacity, voltage, self discharge, internal resistance of the battery and use them together.

3. Sulfation     The vulcanized battery was repaired by Coty. The fuzzy digital control theory was used to measure the state of the battery. At the same time of charging and discharging, the positive and negative frequency conversion particle waves were continuously emitted. In 10 to 20 hours, the hard lead sulfate which crystallized in the battery was removed.

4. Plate softening     After discharging the battery to 10.5V, deep discharge with a bulb for 1-5 hours. Then, the activation instrument was used to activate and repair.
