,(Battery pack structure)

1(Battery modules)

30PCS CBB 36130170-50AH cells,2 parallels and 15serial, make a battery.

2 Battery Management System
,,,,,.
The protection board, provides protection against overcharge, and short circuit, through monitoring single string of cells.

3 charge and discharge standard

•  
• Cell adopted: CBB 36130170-50AH
• :
• Constant charge current: 0.5CA is the best. cell max voltage<3.65V.
•  
• Constant discharge current: 0.5CA, cell min voltage> 2.5v

,(performance):
 

No.	Project	Standard	Testing method
1	Discharge performance in normal temperature	Discharge capacity /standard capacity×100% 0.5CA ≥100%	Charge with 0.5CA standard charge in the condition of temperature 25ºC±5ºC,relative humidity 45%~80% (if there is no especial statement,the charging way is same as this), rest for 10min,separated discharge with 0.5CAto cut-off voltage 37.5V,cycles for three times,One cycle capacity arrive standard, that's to say it is qualified.(The below as the same);
2	Charging keep ability in normal temperature	Rest capacity≥standard capacity *90%	After standard charging,store at 25ºC±5ºC for a month, and then discharge to cut-off voltage 37.5V by 0.5CA. Then measure the capacity of cell.
3	Charge protection strategy test	Charging protection when maximum single cell voltage > 3.65V	,.Charging protection when maximum single cell to voltage 3.65V.
4	discharge protection strategy test	Discharge protection when minimum single cell<2.5V	. After the 0.5CA standard charge full of electricity, then 0.5CA discharge to the termination voltage 37.5V, to confirm the battery discharge protection the minimum single cell voltage
5	Cycle life	Capacity≥ Standard capacity *80%	0.5C Charge&Discharge cycle at 80%DOD,cycles for 4000 times.
6	Storage performance	Capacity can be kept ≥80% Storage for 12months.	After standard charged,let it rest for 12 months as a open circuit, discharging it until 37.5V by 0.5CA, and then measure the leftover capacity. Measure its recovery capacity by 0.5 CA /0.5CA . Undertake 3 cycles, it passes when one cycle meets the standard.

 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 -20ºC~45ºC in warehouse where it's dry, clean and well-ventilated.
 

1. During loading of battery, attention must be paid against dropping, turning over and serious stacking.

. (Warnings and Notices)
,,,:
In order to prevent the battery leaking, getting hot and exploding, please pay attention to preventing measure as following:
 (Warning !)

•  
• Never throw the battery into water, keep it under dry, shady and cool circumstance when not use.
