The objective of this profile is to demonstrate the discharge pulse power (0,1 s, 2 s, 10 s and 18 s) and regenerative charge pulse power (0,1 s, 2 s and 10 s) capabilities at various SOC. The test protocol uses constant current at levels derived from the supplier's maximum rated discharge pulse current, Idp,max. In agreement with the customer, this value may be reduced. Only in the case where the DUT reaches the discharge voltage limit during discharge, shall the current be reduced such that the battery terminal voltage is maintained at the discharge voltage limit throughout the 18 s discharge pulse. The current of the regenerative charge pulse shall be kept constant and shall be calculated as 75 % of the discharge pulse current. Only in the case where the DUT reaches during charging the charge voltage limit, shall the current be reduced such that the battery terminal voltage is maintained at the charge voltage limit throughout the 10 s regenerative charge pulse. The test profile shall consist of an 18 s discharge pulse followed by a 40 s rest period to allow the measurement of the cell polarization resistance. After the 40 s rest period, a 10 s charge pulse with 75 % current rate of the discharge pulse shall be performed to determine the regenerative charge capabilities. After the charge pulse, a rest period of 40 s shall follow
