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

72V 140AH battery need 2 voltage modules.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
