at a specified temperature to ensure the normal operation of a cell.

Terms and definitions:

1 Cell: Basic unit device that converts chemical energy directly into electrical energy, including electrodes, membranes, electrolytes. Ratio of constant-current charging capacity: the ratio between the charging capacity of a cell chargedto3.65V at a certain ratio under the condition of 0% SOC at room temperature and the charging capacity under the standard charging method. Maximum continuous charging current: The maximum current allowed for continuous charging of acell at
a specified temperature to ensure the normal operation of the cell.

First charge in  GOTION 3.2V 27A cell according to 7.2 method; store at 55 ℃± 2 ℃ for 5 h at the specified temperature; then discharge at the specified temperature with 1C current, discharge to 2.0 V, measure the discharge capacity(Ah)and discharge energy (Wh), The ratio of that to the discharge capacity and discharge energy (accordingto7.3)at room temperature is the capacity/energy retention rate at high temperature. According to this method, the discharge capacity at hig. You can also check out 100a cell.
