  • Automotive: EV, HEV, PHEV
  • "Mules" and proof-of-concept products
  • Specialty vehicles
  • Marine
  • Aviation: EV
  • V2G and V2H
  • Distributed energy
  • Peak shaving
  • Power back-up: UPS


This standard Li-Ion BMS controller performs these functions:

  • Manages the cells in the battery pack
  • Measures the battery pack current
  • Reports the status of the battery pack
  • Requests charging and discharging limits
  • Drives contactors and handles precharge
  • Controls cooling

Distributed: electronic assemblies are mounted on cells

  • Mechanically matched with cylindrical, pouch or prismatic cells
  • Minimal wiring (no "spaghetti"); individual cell voltage and temperature
  • Controller communicates with Cell Boards on cells, and with external system

Ideally matched to Li-Ion cells

  • Lithium-ion Polymer(LiPo)
  • Standard lithium-cobalt-oxide (LiCoO2)
  • Lithium-Manganese-Nickel-Cobalt (LiMnNiCo)
  • Nano-phosphate / lithium-iron-phosphate / lithium-ferro-phosphate (LiFePO4)
  • Lithium-manganese-oxide (LiMnO2)
  • Not compatible with lithium-titanate cells (Altair Nano)
  • Not compatible with lithium-sulfur cells (SIon Power)

Ideally matched to plug-in vehicles

  • Compatible with most chargers, motor drivers
  • CAN bus, ignition line input, 12V power

Performs monitoring, evaluation, communication, balancing and protection

  • Monitors the voltage and temperature of each set of parallel cells, and the pack current
  • Evaluates SOC (State Of Charge), DOD (Depth Of Discharge), and SOH (State Of Health)
  • Calculates the pack's internal resistance
  • Determines appropriate CCL (Charge Current Limit) and DCL (Discharge Current Limit)
  • Detects any abnormal conditions and sets a fault accordingly
  • Communicates through a serial port and through a CAN bus, reporting above data
  • Balances the charge through dissipation of excessive energy in most charged cells
  • Protects against over and under-voltage, over and under-temperature, over-current
  • Optional HV Front End tests for loss of isolation and end of precharge current (using a precharge resistor, not supplied)
