In January , 2010, our company, Shandong Hipower new energy group, send 48V100 AH LifePO4 Battery Pack to Shanghai for battery performance tesing.
With testing data automatic generated by testing machine, I could make offer some pictures, the original Excel documents is about 25M,
With the whole Pack discharging, Testing machine logged all 16 pcs of 3.2V 100A cells discharging status, which marked with different colors, to show the consistency of wole battery pack, curves are automatic generated from data in EXCEL,
3 pictures I could offer, in continuous discharge of 3C, 2C, 1C,
That means battery pack continuous discharge current is 300A ,200A , 100A.
3C continuous discharge curve (3.2V 100AH, in 22'C temperature)
2C continuous discharge curve (3.2V 100AH, in 22'C temperature)
1C continuous discharge curve (3.2V 100AH, in 22'C temperature)
At end I also put discharge curves comes from datasheet, that means if the battery performance can not match those curves, customer could directly asking for replacement or send it back with total free.
0.5C discharge curve from battery pack datasheet(48V 100AH battery pack, in 22'C temperature)
battery performance in different temprature(3.2V 100AH, 0.3C Discharge )
