3. Electrical Characteristics & Test Condition.
@Ambient Temperature 25±5℃ & Humidity 45%~75%.
@50% SOC @1kHz AC internal resistance test instrument
After Normal charge, discharge @0.33C current to the end of discharge voltage.
|3||Short circuit protection||
Auto cutoff load when short circuit
Connect the positive and negative of this battery pack through a lead with 0.1Ω resistance.
|4||MAX charge Current||100A||Charging with this current for more than 0.5h and the added temperature of battery pack less than 20℃.|
|5||MAX discharge Current||100A||Discharging with this current for more than 0.5h and the added temperature of battery pack less than 35℃.|
Cycle life (DOD%100)
|≥2000cycle||Discharge with the current of 0.5C until it can’t discharge, and then rest it for 1h. Charge the battery following CC(0.33C)/CV(14.6V) mode to full capacity, and then rest it for 1h. Repeat above process until full charged capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.|
|-20℃||70%||At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage and record charge capacity. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage.|
|8||Charge Retention ability||remain capacity≥96%||
After normal charge, store the battery @25±5℃ for 28days, then discharge capacity @0.33C,the retention capacity accord with criterion.
4. Circuit Protection
The batteries are supplied with a LiFePO4 Battery Management System (BMS)that can monitor and optimized each single prismatic cell during charge & discharge, to protect the battery pack overcharge, over discharge, short circuit. Overall, the BMS helps to ensure safe and accurate running.
