The SOC limit for altering the profile can be detected by one of the following:SOC calculated, i.e. by the BCU;number of cycles (SOC per cycle equal to 1.944%)ampere hours, counted by external measurement;battery voltage upper and lower limit defined by the supplier.After 22h of cycling, 2h of rest shall be taken to allow certain equilibrium whihin the cell chemistry and to bring all cells to a voltage balanced status (this is normally performed by the integrated cell voltage balancing circuitry), followed by the performance check.
