Description technique

Gestion des cellules

  • Management of 7 or 8 lithium cells in series*, compatible with all cell technologies (NMC, LiFe, LiPo…)
  • Management of 4 NTC temperature sensors:
  • 2 digital measurements used by the software
  • 2 analog measurements used by the hardware redundancy
  • Measurements accuracy:
  • Cell voltages: +/- 5 mV
  • Temperatures: +/- 1°C


  • Hardware redundancy for voltage and temperature measurements in order to reach a high level of safety (SIL2 of EN61508 standard)
  • Overcharge and undercharge, tunable by software
  • Overtemperature and undertemperature, tunable by software
  • Overcurrent: 2 levels in discharge, 1 level in discharge, tunable by software
  • Short circuit hardware protection (resettable electronic fuse):
    • Above 41 A for more than 100 µs


  • Passive balancing with a 200 mA bypass current per cell

Power box

  • Integrated power box with MOSFET technology:
    • 40 A continuous current in charge/discharge
    • 40 A maximum peak current in charge/discharge
  • Bidirectional measurement of the battery current
  • Precharge circuit included on the BMS
  • No heatsink required
  • Integrated 12V isolated power supply to power an external controller

Smart functions

  • SOC and SOH calculation
  • Advanced self-diagnostic of the board
  • Communication by CAN bus 2.0B (opto-isolated)
  • Possibility to manage the motor controller and the charger
  • Advanced supervision software
  • Black box integrated with defaults history storage and life counters
  • Possibility to connect two packs in parallel

Power supply/consumption

  • Supply of the BMS directly on the battery pack
  • Low consumption in sleep mode: < 500 µA

Mechanical format

  • 100 mm x 180 mm x 12 mm
  • Can be potted to be used in harsh environment
