The cycle life test is performed by

The cycle life test is performed by combining two test profiles, one is the "discharge-rich profile", where the discharge amount is slightly larger than the charge amount, as shown in table 26 and Figure 6, and another one is the "charge-rich profile", where the charge amount is slightly larger than the discharge amount, as shown in table 27 and Figure 7.The SOC swing range shall be defined by the customer; otherwise, the cycle life test shall be performed between 30% and 80% SOC.By combining the two profiles, the SOC swing range can be utilized over the cycling test. The cycle life test shall be started from the upper limit of SOC with the discharge-rich profile and once SOC reaches the lower limit or the battery voltage reaches the lower voltage limit specified by supplier, the profile shall be switched to the charge-rich profile and continued until the upper SOC limit or voltage limit is reached.
