72V 200AH LifePo4 battery pack for pure electric car, Motive Batteries
3 units 24V 200AH in serires to attain 72V 200AH battery pack.
LiFePO4 battery structure
Protection in 7 aspects
Against vibration, water ingress, high temperature, low temperature, dust ingress, creepage , short circuit
3 features
Light in weight, small in dimesion, attractive in visual appearance
1)Long cycle life (2000 cycles) is several times greater than Ni-MH, Ni-Cd or SLA.
2) Non-Toxic, environmentally-friendly product.
3) High safety
LiFePO4 is an intrinsically safer cathode material than Lithium-ion since exothermic reactions can not occur in batteries based on this material
LiFePO4 cells do not incinerate or explode under extreme conditions
4) Good performance in high-current discharge cycles.
5)offter full solution of battery+BMS +charger, which can protect from overcharge , overdischarge, overheat
336V 100AH battery need 9voltage modules. 105 in series and 20 in parallels.
One BMS include voltage module+current module+current sensor+Host+display+wiring harness
BMS function
1)state of charge(SOC)
2)Voltage of the pack
3)Voltage of the lowest and highest cell
4)Temperature of each box
5)Max charge current
6)Max discharge curretn
7)State of health(HOS)
8)Voltage of individual cells
9)Resistance of the pack and individual of cells
BMS advantages
Lossless shift balancing
SOC with high accuracy
Anti-jamming
Wireless data transmission
Automobile grade interface
Convenient installtation and maintenance
Heat management
Inspecition of capacity of cell
