1. Instruction of the Battery Pack Structure
(1) Battery modules
52 cells, 4 parallel and 13 serial to make a battery module
50 cells, 5 parallel and 10 serial to make a battery module
The BMS 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 for cell
Cell adopted: 18650 2200mAh-3400mAh cells
Constant charge current: 0.2 C 2A -2A is the best charging current, single cell max voltage<4.3V
Constant discharge current: 15-30A is the best discharging current, single cell min voltage> 2.75V
Rapid charge capability: Max charging current 0.5C.
2. Storage and transportation
(1)Based on the characters of cells, proper environment for transportation of 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 -20ºC~45ºC in warehouse where it is dry, clean and well-ventilated.
(4)During loading of battery, attention must be paid against dropping, turning over and serious
3. Warnings and Tips
