The battery will be tested at an ambient temperature of 20 + 5 ° C (68 + 9 ° f)
1. Without the limitation of power supply of overcurrent protection device:
Output UOC: UOC ≤ 30V; 30V
b) ISC outputs the maximum current under any non capacitive load, including short circuit.
c) S maximum output power, with non capacitive load, including short circuit.
d) If the protection is through electronic circuit or positive temperature coefficient device, measure ISC and s for 5 seconds after load application, or 60 seconds in other cases. If multiple protective measures are provided, such as a combination of electronic circuits and positive temperature coefficient devices, the 60 seconds of ISC and s are measured under applied load or no fault.
2. Under the limitation of power supply with overcurrent protection device:
Output UOC: uocs20v; 20V
a) UOC open circuit battery voltage is disconnected from all load circuits.
c) S (VA) - the maximum output VA after 60 seconds of operation under any non capacitive load (including short circuit).
d) During the measurement, the current limiting impedance still exists in the circuit, but the overcurrent protection device is bypassed.
e) The current rating of overcurrent protection devices is based on fuses and circuit breakers, which open the circuit within 120 seconds and the current is equal to 210% of the current rating specified in the table.
Note: the reason for using overcurrent protection device bypass for measurement is to determine the available energy that may cause overheating during overcurrent protection device operation.
