Where Cfade is the capacity fade, in per cent; Crt,tx is the 1 C capacity at current test; Crt,t0 is the rated 1 C capacity at BOL. 7.10.2.2 High-energy battery system The procedure delivers two sets of test procedures, dedicated to battery systems used in dynamic discharge applications followed by a complete charging procedure, see 7.10.2.2.1, and for battery systems used in dynamic discharge applications followed first by a charge sustainable operation within a moderate SOC swing and then followed by a complete charging procedure, see 7.10.2.2.2. Supplier and customer shall agree on the relevant test procedure based on the dedicated application requirements for the battery system. 7.10.2.2.1 Battery systems for dynamic discharge applications7.10.2.2.1.1 Preparation During the test, it is necessary to maintain the DUT temperature by its cooling equipment within a temperature range between RT and 40 °C (i.e. RT during rest periods, certainly higher during operation). If requested by the supplier, additional rest periods can be placed between the cycles in order to keep the DUT within the designated temperature range. The cycle test is performed by combining two test profiles: one is the “dynamic discharge power profile A”, where the amount of discharged energy is significantly lower than the “dynamic discharge power profile B”. The profiles are shown in Figure 9 and Figure 10. The data of the profiles are shown in Table 30 and Table 31 accordingly.
