Why can't lithium batteries be overcharged and overdischarged?

Lithium batteries cannot be overcharged to ensure excellent performance. Regardless of lead-acid batteries or lithium batteries, try to prevent the charging time from being too long, and the charging time should not exceed 8 hours, and try not to attack violent collisions or contact with high-temperature objects. Especially for lithium batteries, the charging time is too long, or waiting until the battery is completely used up before charging is not the correct method. Since lithium batteries have no recall effect, the amount of each charge will not affect the battery's energy storage. On the contrary, assuming that the charging time is too long, it will affect the consistency of the battery pack, thereby affecting the service life. And this reduction in life span is not a recovery, so you should be especially careful not to fill it too full, claiming that 80% is the best. The discharge is the same. There must be a little electricity during the charging time of the battery, and the electric vehicle will not charge if it is not running, so the impact on the battery life is the same. In addition, after the battery is completely discharged, the customer should charge it as soon as possible to prevent charging in a low temperature environment. Assuming that the electric bicycle is not to be charged for a long time, remember to charge it when needed. This not only prolongs the service life of the battery, but more importantly, ensures the safety of the battery function. The safety of electric vehicles is guaranteed from the date of purchase. Therefore, to ensure the safety of electric vehicles during use, customers should start paying attention now when purchasing. At present, the maintenance system of ordinary manufacturers is more complete, and the line data and the interface of each component are more standardized. Customers should not be greedy for cheap, and must choose electric models from regular manufacturers or well-known brands. In addition, customers should also pay attention to the standard operation of electric vehicles and batteries during use to prevent overcharging and overdischarging. The electric vehicle battery adopts a cooling method after heating, and can be charged only after the temperature of the electric vehicle battery returns to normal. The location of the electric vehicle battery device should be as good as possible to ensure good heat dissipation, overheating should be found to be charged in time, and the charger and electric vehicle battery should be checked. When the depth of discharge of the electric vehicle battery is shallow or the ambient temperature is high, the charging time should be shortened. After the electric vehicle battery is discharged to the intermittent voltage, the continuous discharge is called overdischarge. Over-discharge will seriously damage the electric vehicle battery, and the function and cycle life of the electric vehicle battery are very unlucky. In general, when buying an electric car, customers not only have to consider factors such as price and length of travel to judge the quality of a car, but also the contact with line data and parts. The battery should not be short-circuited with the battery, or special care should be taken when using the equipment. The tool should choose the heat preservation method. The battery other than the accessory should be electric. After inspection, there is no short circuit. After all, even in the electric vehicle battery, the wiring standard should be insulated to prevent breaking Stack compression attack, the only way to make electric vehicles safer and more durable to use.
