Correctly charging and discharging electric batteries can extend their service life.

The new national standard is uniformly equipped with lithium batteries as the standard for electric vehicles. As the 'new heart' of electric vehicles, lithium batteries have begun to show their vitality with various advantages. However, compared with the old lead-acid batteries, the cost of lithium batteries is still much higher, and the durability of lithium batteries is always inferior to that of lead-acid batteries, so the correct use of lithium batteries for electric vehicles can prolong its service life as much as possible. . Our daily operation is to charge the battery. Correctly charging the lithium battery is also one of the most direct ways to extend the battery life! Electric vehicle lithium battery manufacturers will explain how to correctly charge electric vehicle lithium batteries. 1 Charging a new battery When charging a lithium battery for the first time, the lithium battery is in a low-capacity self-discharge state when it leaves the factory. Lithium batteries that have been left for a period of time will enter a sleep state (low activity). At this time, the capacity is lower than the normal value, and the use time is shortened accordingly. The capacity loss caused by this situation is that the ions can be reactivated by charging and discharging several times. Some people think that after the lithium battery is activated, it needs to be charged for more than 12 hours, and can be activated by repeated charging 3 times, but in fact this is a huge mistake after all. This is very correct for nickel and lead-acid batteries. , But for lithium batteries, overcharging or overdischarging will cause different degrees of damage to lithium batteries! In fact, the activation of lithium batteries is very simple and does not require special methods. Normal capacity can be restored after 3-5 times of normal charging. 2 When to charge lithium batteries Many users still stay in the state of using lead-acid batteries. This is also a deep-rooted cognitive problem. Many people think that it is better to charge lithium batteries when electric vehicles are exhausted. Because lithium batteries have the number of times of charge and discharge, the use of lithium batteries should be extended in this way as much as possible. However, the results are always surprising. In reality, the under-charge and under-discharge of lithium batteries is a way to keep lithium batteries active for a long time. This is exactly the opposite of lead-acid batteries. The memory function of lead-acid batteries forces users to charge them as soon as possible after the battery runs out. However, if the battery power of the lithium battery electric vehicle has been insufficient, then you should stop and charge the battery as soon as possible, because excessive discharge will directly cause the damage of the lithium battery. In severe cases, the entire battery pack may fail. 3 Overview of Lithium Battery Charging So we need to use the lithium battery correctly and use the correct method to charge the lithium battery. In addition, the activation of the lithium battery for electric vehicles does not require a special method, but according to the standard time and procedures for charging. In the normal use of electric vehicles, lithium batteries will be naturally activated. When the electric vehicle displays a warning that the battery is low, it should start charging in time.
