4. Electrical performance test

Serial number	Project	Standard	Test methodology
1	Room temperature discharge performance	Discharge capacity/nominal capacity × 100%. 0.5C ≥100% 3C ≥95%	At 1 standard atmosphere, the ambient temperature is 20°C±5°C, and the relative humidity is ≤75%RH, the battery is charged at 0.5C standard constant current and constant voltage 25.2V, cut-off current of 0.02C, battery at 20°C±5°C, respectively 0.5C, 3C current discharge until the discharge termination voltage is 15.6V. Three cycles are allowed, and when one of the criteria is met, the requirements are met.
2	Room temperature charge retention capacity	Remaining capacity ≥ nominal capacity × 90% Recovery capacity ≥ nominal capacity × 95%.	The battery is charged at 0.5C standard constant current and constant voltage at 25.2V, the cut-off current is 0.02C, left open for 28 days, and discharged at 0.5C to 15.6V, measuring the remaining capacity of the battery; 0.5C/0.5C measures the recovery capacity of the battery. Can be cycled three times when there is once the standard is met, the requirements are met.
3	Cycle life	Capacity ≥80% × initial capacity	Perform a 0.5C charge/0.5C discharge cycle, and after 800 cycles, measure the remaining capacity of the battery. Perform a 0.5C charge/3C discharge cycle, and after 500 cycles, measure the remaining capacity of the battery.
4	Low temperature discharge performance	Capacity ≥80% of nominal capacity	After the battery is charged at 0.5C standard constant current and constant voltage, it is left at -20°C for 8h, and discharged to 15.6V at 0.5C to measure the remaining capacity of the battery.

5	High temperature discharge performance	Capacity ≥98% nominal capacity	After the battery is charged at 0.5C standard constant current and constant voltage, it is left at 55°C for 4h, and discharged to 15.6V at 0.5C to measure the remaining capacity of the battery.
6	Self-discharge	Capacity ≥ Nominal Capacity ×100% Storage 1 Month ≥92%	The initial capacity of the battery was measured, after the battery was charged as standard, the initial state before storage was recorded, and after 1 month of storage at room temperature, the final state of the battery was measured, and then the discharge capacity of the battery was recorded 3 times at 0.5C/0.5C.
