Lithium for Rechargeable Battery Pack 12.8V40Ah for E-car

 

 

 

Battery modules

 

32 32650-5Ah cells,8 parallel and 4 serial, make a battery.

 

Circuit Protection Board

   The protection board, provides protection against overcharge, and short circuit, through monitoring single string of cells. Also i t enables every battery pack to obtain independent balancing function.

 

Charge/ discharge standards

• Cell adopted: 32650-5Ah.
• Constant charge current: 0.2 C₃A -1 C₃A is the best. cell max voltage <3.9V.
• Constant discharge current:cell min voltage> 2.0v
• Rapid charge capability: Max. charge current1C₃A;temperature increase falls within 15°C is normal while over 15°C will affect the se rvice life of cell.

1) Safety: Currently the safest Li-ion battery, non-incinerated under over voltage of 40V charge, non-explosive under piercing.  

2) Environmentally friendly. Non-toxic materials.  

3)Powerful.

4)Long cycle life: 2000 cycles remain 80% capacity. Other Li-ion battery is only 300-500 cylces. Ni-Cd /Ni-MH and Lead battery is also only 300-500 cycles.
