What are the common defects and repair methods of lithium-ion batteries?

The common defects and repair method of lithium-ion battery, the common defects of lithium-ion battery of electric cars: (1) no display of electric car, no output of the battery, no charging of the battery, etc. (2) Charger failure lead to charging failure. The battery cannot be fully charged. The charger doesn't change the charging light. Charging time becomes shorter or longer. (3) The lithium-ion battery has normal voltage, but is out of power for short distance. After stopping it for a while, it can work again. The cycle life sometimes is normal, sometimes is abnormal. (4) The protection board of lithium-ion battery itself is damaged, and affects that the lithium-ion battery can't work normally. The battery protection board is not working, which damages part of the battery cell.

Electric lithium battery repair methods

1. To match groups: the whole cell loss after ring, we tend to electric lithium battery charge and discharge test, a group tend to be found in the inspection in 50% of the battery is not damaged. Its reason is in series battery pack, the individual battery behind the form a complete set of functional decline, so that the whole battery.

2. Hydrating: lithium batteries used in the electric battery for about four months a hydrating, can prolong the service life of the battery, prolong the time averaged more than 3 months. It should be noted that, every time after filling water, batteries are used is in a state of charging the battery from the "quasi barren solution" to "barren solution" state, and the charge is beneficial to improve the battery capacity.

3. Eliminate sulphide: using battery repair equipment, to remove sulfide the battery.

4. The particle generator: take a particle generator in parallel on the battery, the battery repair. This kind of method to repair electric lithium battery is better, but because of the repair is complete, so, if there is no discharge, for continuous use of electric lithium battery, is often completely eliminate the possibility of a battery sulfide.

5. Comprehensive repair method of electric lithium battery: lithium-ion batteries need for regular electric inspection, and sulfuring and hydrating in time. Charge the single battery and set up the battery pack again. If it is a free maintenance, generally do not need to add water. If you need to add water, first check the electrolyte density of electric vehicle battery, and choose proper concentration or no concentration of water supplement according to the different situation, in order to increase battery capacity or prolong cycle life.
