电池容量150AH。标称电压3.2V,串数15
设计容量应该填多少?
Star Xu:
Design capacity has both current capacity and power capacity. See the technical reference manual sections 9.2 and 17.26. The design capacity value in defaults is 4 cells x 3.6V x 4400 mAh = 63360 mWh = 6336 10mWh
Design Voltage is explained more with the command 0x19, see the technical reference manual 17.27. It is the cell voltage.

15*3..2*150000=7200000 寄存器溢出了,怎么处理?

回复 BMS:
就算是100mWh 也是溢出了哦,另外请问一下,100mWh / 10mWh在那个寄存器设置,BQ78350

回复 BMS:
bq78350-r2支持IPSCALE ,但是最大*10,您的容量太大,FCC最大值65535,单位10mWh,scale*10,最大值就是6553500mWh,您的容量7200000mWh还是超出范围,

回复 Star Xu:
我也知道超出范围,那改如何处理?
BMS:
回复 Star Xu:
介绍不是可以最大支持320A,320AH的嘛?

回复 Star Xu:
规格书最大的值是32767何来65535?
Star Xu:
回复 BMS:
抱歉,FCC最大值是65535
