Lithiumate pro
Professional distributed Li-Ion BMS
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 256 cells (~ 900 V), in up to 16 banks
- Supports all cell form factors, and most Lithium chemistries
- 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 and RS232 communications
- Fully configurable, field programmable
- Cable mount Hall Effect current sensor
- Contactor drivers with precharge
- Pack isolation loss detection (optional)
- Compatible with most chargers, motor drivers

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 a 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)
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)
