7.Cell temperature rise for CATL 280Ah battery cell

The temperature rise refers to the surface temperature of the cell after discharge minus the surface temperature of the cell before discharge. The measurement of the temperature rise of the cell should be carried out in a room where the ambient temperature is relatively stable and the space is large enough. For each cell temperature measurement, a calibrated temperature sensor that records time data should be selected.

No.	Parameter	Specification	Condition
2.5.1	Continuous dischargetemperature rise	≤10°C	The cell is discharged in the standard discharge method.
2.5.2	Pulse dischargetemperature rise	≤5°C	The cell is discharged at 500A for 10 s under any state ofcharge.
