How to charge lithium-ion batteries for electric vehicles

1. Charging a new battery Generally, the life of a lithium-ion battery starts from the moment it leaves the factory, and it is in a low-capacity self-discharge state. After the battery is left for a period of time, it will enter the dormant state. At this time, the capacity is lower than the normal value and the use time is also shortened. The capacity loss caused by this self-discharge is reversible and can be recovered by charging the battery. This process is like when a person is stationary, energy consumption is at a low level, but there are still a small amount of cell tissue working to ensure the normal operation of the human body. Regarding the charging of lithium-ion batteries, there is a misunderstanding that the first charging time of lithium-ion batteries must exceed 12 hours, and it can be activated after repeated charging three times. In fact, overcharge and overdischarge will cause varying degrees of damage to lithium-ion batteries, and this statement is also for traditional nickel batteries. Lithium-ion battery activation does not require special methods. Generally, the battery can be activated after 3-5 normal charge and discharge cycles to restore normal capacity. 2. When is the lithium-ion battery charged? Many people think that the electric car is charged when it is dead. In fact, yes, because the number of charging and discharging of lithium-ion batteries is limited, the lithium-ion batteries should be used up as much as possible to recharge. But it must be implemented in accordance with actual life requirements. The remaining power of the electric car later than today is not enough to support tomorrow's journey, and the conditions for charging are not available the next day, then it should be charged in time. In fact, the principle of insisting on using up the remaining power of the battery and recharging is not an extreme practice of using the battery completely. If the electric vehicle is still not charged until it is unable to drive after a warning that the battery is too low, the battery may be over-discharged and the voltage may be too low, shortening the battery life.
