Introduction to lithium battery pre-charging use

Since lithium batteries have a high energy ratio, if they enter the fast charging mode directly, they will damage the lithium batteries, affect their service life and may cause safety hazards. When the lithium battery is charged, because the battery may be damaged when the current is too large, it is pre-charged first, and the active material is activated first, and then the battery is charged normally. Although the current lithium battery has a built-in circuit protection board in the design process, the chance of overcharging and overcharging is usually very small, but if the battery is not precharged at first, it will bring many hidden dangers, such as the failure of the protection board and a long time. When the battery is over-discharged, it will cause difficulty in the recovery of the active material. It is necessary to charge the battery to 2.5V to 3.0V with a small current and then convert it to a fast charge. The pre-charged small battery can effectively deal with the charging problem of the over-discharged battery. Therefore, experts recommend that consumers correctly understand the importance of lithium battery pre-charging. The reason why lithium battery has the pre-charging function during the design process is that this is the purpose. Therefore, newly purchased batteries must be pre-charged and selected appropriately. The constant current value is for charging the battery.
