What kind of electric vehicle battery is scrapped?

The electric vehicle battery is the energy source of the electric vehicle, and it is a kind of consumable. How to determine that the electric vehicle phone is scrapped? The author tells you.　　1. The battery’s storage capacity is less than 60%. After maintenance, there is no obvious improvement, and it can basically be scrapped.　　Reason: During the use of lead-acid batteries, the performance will be greatly reduced after the capacity decays to about 60%. The components inside are basically deteriorated, the capacity decay gradually accelerates, and the charge and discharge capacity will soon be completely lost.　　2. It will be fully charged in a short time, and it will be out of power after riding less than a few kilometers.　　Reason: The battery is aging or a single cell in the battery pack may be out of order, resulting in the overall battery storage capacity is small, easy to charge, of course, the cruising range is also very short.　　3. When the battery is charged or used, its shell becomes severely hot and hot.　　Reason: The cause of heat generation is that the active material on the electrode plate is severely peeled off, the internal resistance increases, and the heat generation increases. At this time, if you open the battery safety valve to check, you will see that the electrolyte is black, and it cannot be repaired if it is seriously invalid. At this time, the battery self-discharges quickly, and sometimes it runs out soon after charging.　　4, the swollen battery or the outer shell is deformed and cracked.　　Due to long-term high-current charging or overcharging, the battery bulges, and some of the bulged battery plastic shells are squeezed and broken. Such batteries can no longer be brought back to life simply by repairing.　　 Therefore, users of electric vehicles should always pay attention to the maintenance of the battery. When there is a problem with the battery, they must find a professional repair shop for inspection and repair. If the battery must be replaced, the battery must be selected.
