Charge and discharge parameters of polymer lithium ion battery

The charge and discharge parameters of polymer lithium-ion batteries Polymer lithium-ion batteries have the same charge and discharge characteristics as ordinary lithium-ion batteries, but the specific parameters are slightly different. According to the current general technical level of polymer lithium-ion batteries, it is necessary to set the charge-discharge and self-discharge process parameters. Charging, 1. The lithium-ion battery charger used for charging should meet the three-level characteristics of lithium-ion battery charging, and have and complete the three stages of pre-charging, constant current charging and constant voltage charging. Therefore, the original charger is the best choice. 2. Ambient temperature: 0~40℃. 3. Charging cut-off voltage: 4.2v Even if multiple batteries are charged in series, a balanced charging method should be used to ensure that the voltage of a single battery does not exceed 4.2v. 4. Charging current: 0.2c for non-emergency use, generally less than 1C. Second, discharge 1. Ambient temperature: Discharge is the working state of the lithium polymer battery, and the required temperature at this time is -20~60℃. 2. Discharge termination voltage: The current standard is 2.75v, some can be set to 3V. 3. Discharge current: Polymer lithium ion batteries also have large current and large capacity types. The current of polymer lithium ion batteries that can be discharged with high power should be controlled within the product specifications. 3. Self-discharge is generally considered to be between 40% and 60% of the storage capacity of lithium polymer batteries. Of course, this is not always possible. Spare lithium polymer batteries will also have self-discharge, and long-term self-discharge will cause over-discharge. Therefore, prepare with both hands. 1. Regularly charge, maintain 3.6v to 3.9v voltage. Li-ion batteries have no memory effect and can be recharged at any time. 2. In order to ensure that the voltage at the discharge terminal is not destroyed, if an alarm of insufficient power occurs during use, the corresponding equipment should be decisively stopped.
