3. Test Conditions
3.1 Standard Test Conditions
3.1.1 Unless otherwise specified, all performance tests is required conducted at temperature 25℃±2℃, Humidity less than 45%~75%RH.
3.1.3 Unless otherwise specified, the tested product is required unused within two month after outgoing.
3.2 Standard Charge Mode
"Standard Charge" means at 25±2℃ charge to limit voltage with 0.33C constant current, then charge with constant voltage until current less than 0.02ItA.
3.3 Quick Charge Mode
" Quick Charge" means at 25±2℃ charge to limit voltage with 0.5 C constant current, then charge with constant voltage until current less than 0.02ItA.
3.4 Standard Discharge Mode
"Standard Discharge" means at 25±2℃ discharge to the cut-off voltage with 0.33C current.
3.5 Quick Discharge Mode
"Quick Discharge" means discharge to the cut-off voltage with 0.5C current.
4. Product Performance
After Normal charge, discharge @0.33C current to the end of discharge voltage.
@50% SOC @1kHz AC internal resistance test instrument.
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.
Cycle life @DOD100%
After Normal charge, discharge @0.33C current to the end of discharge voltage. Repeat above process until discharge capacity reduce to 80% of initial value.
Capacity @specified temperature
Capacity @ 25℃
Capacity retention rate
|After normal charge, store the battery @25±5℃ for 28days, then discharge capacity @0.33C, the retention capacity accord with criterion.|
|3.8||Heating function||Low temperature charging heating||
Heating opening condition
Below the charging temperature protection -2℃
Temperature is greater than -30℃ (allowed to open the heating film the lowest temperature)
Satisfy the above two conditions to start heating
Heating closing condition
Stop heating if the temperature is greater than the ending temperature of heating;
The discharge state stops heating;Under low temperature protection, stop heating after heating for more than one hour.
5. Protective circuit specification
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.
