LiFeBATT Battery Management

LiFeBATT has two different approaches to battery management in order to provide the most optimum solution for the application

1. BMS circuit boards• Used for small applications up to 100 amps

2. VMS circuit boards• Used for large applications over 100 amps

© 201444

LiFeBATT Battery Management

BMS Circuit Boards• Used for applications up to 100 amps• The BMS boards have Mosfet switches on the

board that can switch up to 100 amps

VMS Circuit Boards• Use in conjunction with external contactor relays

that can switch from 100 amps to 1000 amps or more

• An Intermediary Module (IM) with microprocessor control is used to control the contactor relays

Lithium Battery Charging Methods

• Charge each cell individually via wires going to each cell

• Shunt current away from the high cell group via the balance tap

• Shut off charge and bleed current off the high cell group until it’s discharged a bit, then resume charging
