How to detect and repair the lithium battery of electric vehicle?

Professional electric vehicle lithium battery pack inspection method 1. After the battery is fully charged, connect the battery, ammeter, and resistance wire. 2. The internal circuit of the battery is open. Some electric vehicle lithium battery packs have an internal open circuit, which is manifested as the battery has voltage and no current, and the vehicle has electricity and the motor does not rotate. If the vehicle is normal after replacing a set of new batteries, it is a battery problem. Repair method of electric vehicle lithium battery pack 1. Regrouping: After the whole group of batteries is damaged, we often carry out charge and discharge inspections on electric vehicle lithium battery packs. During the inspection, it is often found that 50% of the batteries in a group of batteries are unbalanced. No damage. The reason is that in the series-connected battery pack, individual batteries lag behind, resulting in a decline in the function of the entire battery, so that the function of the entire battery is reduced. 2. Water replenishment: replenishing the lithium battery of the electric vehicle that has been used for about 4 months can extend the service life of the battery by an average of more than 3 months. It should be noted that after each replenishment of water, the battery is in an overcharged state to turn the battery from a quasi-lean liquid to a lean-liquid state, and this overcharge is beneficial to increase the battery capacity. 3. Eliminate vulcanization: use battery repair equipment to eliminate vulcanization of the battery. 4. Particle generator: Take the particle generator in parallel with the battery to repair the battery. This method is better for repairing lithium battery packs for electric vehicles, but because the repair is relatively thorough, if there is no over-discharge, the possibility of battery vulcanization is often completely eliminated for the lithium batteries of electric vehicles that are used continuously.
