Soft Pack polymer lithium battery as a lightweight and flexible battery type, it is widely used in mobile devices, electric vehicles, energy storage systems and other fields. The correct charging method is crucial to the performance, service life and safety of soft-packed polymer lithium batteries. This article will introduce how to choose the best charging method to ensure the best performance and safety of the Soft Pack polymer lithium battery.

1. Common charging methods of soft pack polymer lithium battery:

• constant current charging: Charge to the set voltage value with a fixed current.

• Constant voltage charging: After reaching the set voltage, the constant voltage is maintained for charging.

• Constant current and constant voltage charging: Constant current charging is adopted first, and when the battery voltage reaches the set value, it is switched to constant voltage charging.

2. How to choose the best charging method:

• consider battery specifications: Different types of soft-packed polymer lithium batteries may have different charging methods of recommend, and the best method should be selected according to the manufacturer's suggestions.

• Charging rate: According to the battery charging rate guidance, select the appropriate charging current and voltage to ensure that the charging rate is within the range of recommend.

• Battery Status: For new batteries and batteries that have been used for a period of time, the charging method may be different, and the appropriate charging method should be selected according to the battery status.

• Ambient temperature: Under high temperature or low temperature environment, the charging characteristics of soft pack polymer lithium battery will be different, and the appropriate charging method should be selected according to the ambient temperature.
