What are charging efficiency and discharge efficiency?


Charging efficiency refers to the measure of the amount of chemical energy consumed by a Battery during its charging process into a chemical energy that the Battery can store. Mainly affected by the Battery process, formulation and battery operating environment temperature, the higher the general ambient temperature, the lower the charging efficiency.


Discharge efficiency refers to the ratio of the actual electric quantity discharged to the end point voltage under a certain discharge condition and the rated capacity. It is mainly affected by factors such as discharge rate, ambient temperature and internal resistance. Under normal circumstances, the higher the discharge rate, the discharge The lower the efficiency. The lower the temperature, the lower the discharge efficiency.
