Description technique

Cell’s management

  • Management of 10 lithium cells in series, compatible with all cell technologies (NMC, LiFe, LiPo…)
  • Management of 1 NTC temperature sensor
  • Measurements accuracy:
    • Cell voltages: +/- 40 mV
    • Temperatures: +/- 1°C

Protections

  • Over-current software protection:
    • several configurable levels during charge and discharge phases
  • Overdischarge, overcharge, overtemperature protection
  • Short circuit hardware protection (electronic fuse):
    • Above 45 A for more than 100 µs

Balancing

  • Passive balancing with a 35 mA bypass current

Power box

  • Integrated power box with MOSFET technology:
    • 15 A continuous current in discharge
    • 30 A maximum peak current in discharge
    • 17 A continuous current in charge
  • Bidirectional current measurement with +/-5 % accuracy
  • Precharge circuit included on the BMS

Smart functions

  • SOC and SOH estimation
  • Management of a switch to wake up the battery
  • Automatic detection of the charger connection with wake up of the BMS
  • Advanced self-diagnostic of the board
  • Communication by CAN bus 2.0B
  • Advanced supervision software
  • Black box integrated with defaults history storage, life counters and timestamp
  • BLE: Bluetooth Low Energy / RFID (optional)
  • Data saving on SD Card

Power supply/consumption

  • Supply of the BMS directly on the battery pack
  • Very low consumption in sleep mode: < 60 µA

Mechanical Format
