 Test quality 

 

1, We are not only sell batteries, but also provide expertise to help customer design their own custom batteries.

2, For the raw material: We used Ni1/3Co1/3Mn1/3 positive pole material for electric bike battery. The name is Ternary Li ion battery (Li-NiCoMn). It has high energy density, deep cycle performance, long cycle life (>1000times 1.0C, IEC standrad) and with lower cost. It is the newest generation Li-ion rechargeable battery for high power applications, such as EV car, E-scooter and E-bike.

3, Strict Quality Control: Cell test and battery pack test before producing & delivering.

As usual, we produced a batch of cells, and need do below test firstly.

a) capacity test, b) high current discharge test, c) low temperature test, d) cycle performance test, e) short circuit test, f) overcharge test, g) crush test, h) impact test, i) vibration test, j) hot test.

After the cell is passed test, we will build the pack as below procedure.

a) inner resistance test, b) capacity grading, c) cells welding, d) cells combination, e) welding BMS & cable, f) high & low temperature test, g) charging & discharge test, 10times cycle. h) packing, i) drop test, j) delivery.
