2.2 Battery Pack Electrical Characteristics

No.	Items	Standards	Testing Methods
1	Internal Impedance	Impedance ≤20mΩ	Under 20±5℃ Environment Temperature , the Usage Frequency of Fully Charge( 1KHz) , Use AC Internal Impedance test machine to test
2	Nominal Capacity	200Ah	Rest for 0.5~1 hour after fully charge, Using electrical loader to connect with the battery output port, and discharge with constant current 0.2C till it can’t discharge. Do the cycle three times, if there is one time that the discharge time is equal or more than 285minute , you can stop.
3	Short circuit protection	No load ability after short-circuit .comeback capability of loading after remove the lead away,	Short the pack with the lead (<50mΩ). If remove the lead away, connect the electronic loader with P+, P- of protection board again, so load ability comes back.
4	Allowed Maximum continuous charge Current	200A	charging with 200A for more than 0.5h and the added temperature of battery pack less than 20℃.
5	Allowed Maximum continuous discharge Current	200A	Discharging with 200A for more than 0.5h and the added temperature of battery pack less than 20℃.

6	Over Current Protection	500-800A	Using electron load connect with output side, discharge with 500A for about 2sec Discharge with 800A for less than 20 millisecond,
7	the delay time of over current protection	10.0-50.0ms	Using electron load connect with output side, discharge with more than 800A and record the voltage wave of output side with oscillograph . Numerating the time of voltage from wave to zero for voltage
7	cycle life	Discharge Capacity ≥80%	Discharge it with the current of 50A to the cut-off voltage, and store it for 15min.Charge a battery with the current of 50A, then keep the voltage and current constant and continue to charge it until completed . After storing the battery for 15min. The test is to be conducted as per the above cycles. The cycle should be 1000 times. At the 1001 times discharge capacity should not be less than ≥80% with 20A.
8	Discharge Temperature Characteristics	The ratio between discharge capacity and charge capacity should be not less than the following value	At 20±5℃ discharge the battery with the current of20A to the cut-off voltage and record charge capacity. Store the battery at the following temperature for 2h and discharge the battery with 20A to the cut-off voltage.
		Discharge Current	Discharge Temperature
		Discharge Current	-20℃	0℃	25℃	55℃
		0.2C	60%	80%	100%	95%
9	Charge Retention	remain capacity≥90%	At 20±5℃ completely charge and store it for 28days,and then discharge it with 20A to the cut-off voltage. (We suggest charge the battery every three months)
10	Over Discharge Protection furbish	Charging With20A	Charge the battery with 20A for 5min and measure the output voltage (≥16V)of the battery pack. The battery should have load.
