4.4.3 Cell Swelling Force
The inherent characteristics such as the rebound of the electrode thickness may lead to cell
expansion during use which generates force on the clamp.,and the force increases with the
attenuation of the cell capacity.The cell swelling force at BOL and EOL(60%SOH)is shown
below:
Table 16 Cell swelling force parameters
Swelling Force
BOL
≤3000 N
70%SOH
≤40000 N
60%SOH
≤50000 N
Customer shall fully consider the influence of the cell swelling force when designing the module.
4.4.4 Recommended Temperature Collection Points
The recommended temperature collection points are the poles or code when collecting temperature
of the cell surface.
