The sudden power outage of the Pacific Automotive Network battery is because its voltage is not sufficient, the power has been discharged and it is time to recharge it. 1. Determine the cause of the lithium battery failure and repair the lithium battery to determine whether it can be repaired or not. 2. Repair the lithium battery after water enters the battery. The cell voltage will not last long and can usually be repaired. That is, if you find that the battery cannot be used normally, you should find a professional for repair. time.
If you find a battery with a large voltage difference, you should first determine whether it is caused by the protection plate or the battery core, for example, in a 10-string battery , 9 of them; are 3.85 V, and a single string is 3.85 V. The string voltage is 2.55 V. AWith such a significant voltage difference, this is probably due to the self-consumption of the batteries in the chain.
The easiest way is to remove a nickel plate from the chain and throw it away for a long time. The battery cell with the voltage drop is broken, and you can only find a replacement one (of course the replaced one). the battery will be Cores must come from the same manufacturer and have the same basic parameters); another way is to repair the lithium battery by subtracting and merging (for example, 10 series and 5 parallel batteries are replaced with 10 series and 4 parallel batteries).
The length of time the battery has been used can be used to determine whether it has maintenance value. If it only lasts a year or two, it can be repaired. If it has been used for 4 or 5 years. will have no maintenance value. You can also judge whether it has maintenance value viabattery. When discharging to 10A, the voltage drop is very large, which indicates that the battery life of this battery has been reduced and there is no maintenance value. .
If the battery pack is tested before discharging and the voltage of each string is essentially around 3.80 V, but when the entire pack is discharged the cell voltage drops to 3.2V and the discharge time is short, it means the battery has not been repaired. Value Lithium Battery Repair.
