Battery pack structure:
1 )Battery modules
184 32650-5Ah cells,8parallel and 23serial, make abattery.
2) Protective board
The protection board, provides protection against overcharge, and short circuit, through monitoring single string of cells. Also it enables every battery pack to obtain independent balancing function.
3)Charge/ discharge standards
Cell adopted: 32650-5Ah
Constant charge current: 0.2 C5A -1 C3A is the best. cell max voltage﹤3.9V.
Constant discharge current: cell min voltage> 2.0v
Rapid charge capability: Max. charge current1C5A;temperature increase falls within 15°C is normal while over 15°C will affect the service life of cell.
Charge and discharge curve:
Storage and Transportation:
1.Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
2.During transportation,50% SOC must be kept to ensure that short circuit, appearance of liquid in the battery or immersion of battery in liquid never occur.
3.Battery should be kept at -20℃～45℃ in warehouse where it's dry, clean and well-ventilated.
4.During loading of battery, attention must be paid against dropping, turning over and serious stacking.
