Impact of Discharge Duration on the Battery Power Output

6 Impact of Discharge Duration on the Battery Power Output 

The power output of the battery is zero at the beginning of the duration and remains low during the discharge duration not exceeding the first 2 min., as illustrated by the data presented in Table 6.16. The power output remains fairly constant, particularly in the case of a 20 kW battery over the discharge duration ranging from 3 to 13 min., as shown in Table 6.16. 

These data indicate that the battery power output remains fairly constant over the discharge duration ranging from 2 to 12 min., which represents about 60% of the duration in each case. The battery loses output power by approximately 50% between the last 2 min.
