What are the problems with lithium batteries for electric vehicles?

There are five major problems with lithium batteries for electric vehicles. Pay attention to 1. Overcharge will cause battery bulge; 2. Overdischarge will damage the battery life, and the damage caused is irreversible; 3. Excessive current during discharge will also cause damage to the battery. Damage, this damage is also irreversible; 4. Electric vehicle lithium battery packs are composed of multiple batteries in series and in parallel, which requires high consistency of the batteries, even though the manufacturers have made electrical The battery pack is used for a long time, but the voltage of each string of batteries will be inconsistent due to battery errors during long-term use, resulting in a decrease in the energy output to the entire set of battery packs, and then a sudden power failure during use , Sudden decrease in schedule, unsatisfactory charge, and incomplete discharge. 5. Lithium batteries have very high environmental conditions for use. If the temperature is too high or the temperature is too low, the self-discharge rate of the lithium battery will be much higher, especially the high temperature will greatly reduce the battery life.
