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 (for timing and current, see Table 5 and Figure 2). NOTE For the testing of battery systems, the BCU delivers, e.g. depending on actual temperature and SOC of the DUT, the maximum allowed operating limits of the DUT via bus communication to enable the test bench equipment to maintain the DUT at all times in specified operating conditions. For the testing of battery packs, the supplier is requested to deliver all necessary operating limits for the DUT in order to adjust the test bench equipment to maintain the DUT at all times in specified operating conditions.
