Lithiumate HD Master Overview

 

Professional distributed Li-Ion BMS

  

 

 

Lithiumate HD master

 

This BMS monitors, evaluates, balances and protects a Li-Ion battery pack.

  • Off the shelf, plug-and-play
  • For professional applications: commercial grade, metal case (not sealed)
  • Distributed (a cell board is mounted on each cell: measures voltage and temperature, balances the cell)
  • Minimum number of wires in HV pack, single wire to adjacent cell boards
  • For large packs: up to 255 cells (~ 900 V), in up to 16 banks, and up to 16 strings in parallel
  • Supports all cell form factors: prismatic, small & large cylindrical, pouch
  • Supports mid-voltage Lithium-ion chemistries:
    • Lithium iron phosphate (LFP): LiFePO4 , LiFeYPO4
    • LiCoO2 (LCO) - Lithium cobalt oxide
    • LiMn2O4 (LMO) - Lithium manganese oxide
    • LiNiMnCoO2 (NMC) - Lithium nickel manganese cobalt oxide
    • LiNiCoAlO2 (NCA) - Lithium nickel cobalt aluminum oxide
  • Protects cells from over current, under/over voltage, under/over temperature
  • Dissipative (passive) balancing (top balance)
  • Sophisticated, digital technology: reports each cell's voltage and temperature
  • CAN communications
  • Fully configurable, field programmable
  • Cable mount Hall Effect current sensor
  • Contactor drivers with precharge
  • Optical isolation between pack and low voltage circuit
  • Pack isolation loss detection (optional)
  • Graphics User Interface

General description of the professional distributed Li-Ion BMS

 

Ideally matched to work in high power Li-Ion battery packs

  • Up to 255 cells in series (~840 V), no limit to cells in parallel, isolated
  • No limit to cells in parallel, up to 600 A (higher currents available)
  • Includes contactor drivers, a cooling fan interface and an interlock input

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)

 

Applications

  • 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
