5. Battery Pack Electrical Characteristics

 

5.1 Testing Conditions (Unless Specially Requirements)

Temperature:20±5℃ Related Humidity: 45~75%

Atmosphere Pressure: 86~106kPa

The testing items under the Shipment Voltage(12.8-13.6V )

 

5.2 Battery Pack Electrical Characteristics

 

No. Items Standards Testing Methods
1 Internal Impedance
Impedance ≤50mΩ
Under 20±5℃ Environment Temperature , the Usage Frequency of Fully Charge( 1KHz) , Use AC Internal Impedance test machine to test
2 Nominal Capacity 75Ah 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 5A charging with 5A for more than 0.5h and the added temperature of battery pack less than 20℃.
5 Allowed Maximum continuous discharge Current 30A Discharging with 30A for more than 0.5h and the added temperature of battery pack less than 20℃.

 

 

6. Reliability Test

 

6.1 Testing condition (Unless Special Requirements)

Temperature:20±5℃ Relative Humidity: 45~75%

Atmosphere Pressure: 86~106kPa

All testing under full capacity(13.2-13.6V)

 

6.2 Reliability Test

 

No. Items Standards Testing Methods  
1 Vibration Testing The appearance of battery should not leakage, break or explosion Fix a charged battery on a vibrating table, vibrate it for 90 minutes in three mutually perpendicular directions at the 0.8mm resonance. The frequency is to be varied at the rate of 1hz/min between 10 and 55 hertz.  
2 High Temperature Discharge Testing The battery should be no remarkable breakage, distortion. Discharge time should not less than 255mins Place a full charged battery under the environments of 55℃ for 2 hours. Discharge it at the current of 200mA to the cut-off voltage. Then keep it at 20℃±5℃ for 2 hours.  
3 Low Temperature Discharge Testing The battery should be no remarkable breakage, distortion. Discharge time should not less than 180 minute Place a full charged battery under the environments of -20℃ for 15-24 hours. Discharge it at the current of 200mA to the cut-off voltage. Then keep it at 20℃±5℃ for 2 hours.  
4 Constant Humidity & Temperature Testing The battery should be no remarkable breakage, distortion. Discharge time should not less than180mins Place a full charged battery under the environments of 40℃ and 90% - 95%RH for 48 hours. And keep it in the room temperature for 2 hours. Then discharge it at the current of 200mA to the cut-off voltage.
5 High & Low Temperature Storage The battery should be no remarkable breakage, distortion. And charge/discharge normally Place a full charged battery in a oven with 55±2℃ for2 hours, then keep it under 20±5℃ for 4hrs, then place it in a oven with -20±2℃ for 2 hours, then keep for 4 hours under 20±5℃, cycle as high temperature-normal temperature-low temperature-normal temperature-high temperature for 10 times
 

7. BATTERY PACK SAFETY TEST 

 

7.1 Testing condition (Unless Special Requirements)

Temperature:20±5℃ Relative Humidity: 45~75%

Atmosphere Pressure: 86~106kPa

All testing under full capacity(13.2-13.6V)

 

7.2 Battery Pack Safety Test  

 

No. Items Standards Testing Methods
1 Short-Circuit The battery should be no remarkable breakage, distortion. And charge normally. Use a resistor with less than 0.05Ω to make the battery short circuit for 1 hour. The appearance and characteristics are normal.
2 Over Discharge Protection Test The battery should be no remarkable breakage, distortion. Appearance and charge are normal. Discharge the battery at the rate of 20A with the load of 30Ω for 24h . Charging for 10sec with specified adapter , and check the voltage(≥8.0V)
3 Impact Test The battery should be no explosion or catch fire Place a full charged battery on a flat and put a stainless steel stick (Diamond 7.9mm) in the middle of the battery upright . Beat the steel stick with 9.1Kg
