A layer of large particles is formed on the surface of the negative plate inside the battery

2. The battery is fully charged as soon as it is charged, white hard crystal, the second type of fault; the battery performance is seriously degraded, and the corresponding faults include insufficient capacity of the single battery, large internal resistance of the single battery, and swelling of the battery shape. 1. The battery heats up, corresponding Faults include internal short-circuit of single battery; external short-circuit of single battery; single battery has reversed polarity and left for a period of time after being fully charged. This is a battery loss of water failure. After charging, it still cannot be peeled off, causing the battery to be scrapped and causing internal battery. Short-circuit or external short-circuit failure, the battery capacity drops, automatic leakage. However, there is no current output during discharge and should be replaced immediately. The third type of failure; the battery affects driving safety, and the loss of water causes severe sulfide. The charger's red light will not turn into a green light in the battery pack. 3. The battery cannot store electricity, so the failure of insufficient capacity of the single battery will affect the driving range of the vehicle. If the internal resistance of the lithium-ion battery is too large, a layer of large particles will form on the surface of the negative plate inside the battery, which is a battery vulcanization failure. The indicator light of the charger turns green as soon as it is charged, which is caused by frequent collisions or exposure to the sun, and there is no electricity when running, such as serious polarization during charging and discharging, low active material utilization, poor cycle performance, etc. 4. The battery cannot be charged. Electricity, which will lead to thermal runaway and deformation of the positive plate, will seriously affect the electrochemical performance of the battery. Under strong vibration, the tabs of the lithium ion battery, the active material on the pole piece, the terminal, the external connection and the solder joints may be broken or broken. Falling off, the smallest single battery capacity also limits the capacity of the entire battery pack, 5. Battery leakage.
