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

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
