Lithium battery custom manufacturers: introduce to you what are the characteristics of lithium batteries
Lithium battery (lithium battery manufacturer) charging precautions and charging principle:
1. Charging
The safe working voltage range of lithium batteries (customized lithium batteries) is 2.8~4.2V. Below or higher than this voltage range, the lithium ions in the battery will become very unstable and may even cause accidents. To ensure that the battery is within the safe range , Need a dedicated charger. Although the lithium battery has a protective plate, the charger should be unplugged after it is fully charged.
Second, activate
Before charging the lithium battery (custom manufacturer of lithium battery), the charger will use a small current to supply power to the battery, and at the same time detect the battery voltage change, and gradually increase the current until the set value. This process can be seen as an activation or test charge.
Three, constant current transformer charging
The charger charges the battery with a constant current. As the battery voltage increases, the charger also increases the charging voltage to speed up the charging speed.
Four, variable current and constant voltage charging
When the battery reaches 4.2V cut-off voltage, the battery is only charged about 70% (not fully charged) at this time. At this time, the charger continues to charge the battery with a constant voltage and gradually decreasing current until the value is less than 0.1A and the battery voltage continues to rise before stopping charging.
