This device reads out cell data from Battery Cell Controller IC and populates this, readable, on the CanBus (BGTW Firmware).

For BMS functionality buy the BMS firmware version. BlueBMS for vehicles usages and ESS BMS for Energy storage communications and functions.

This device is the bigger brother of the CMC MAX.


By using multiple transceivers this BMS reads out cell data from
multiple OEM batteries. The BMS version of the firmware controls relays and hybrid inverters etc. The BGTW firmware populates data on the CanBus.

This device allows connecting 6 complete KONA Packs of 64kw.
The total connected storage capacity will then be 384kwh.

The device carries*:

  • 3 MAX ports; ( allowing approx. 30 CMC’s per channel);
  • 2 Isolated CANBus interfaces ;
  • 5x Digital outputs*;
  • 3x Analog / Digital Inputs;
  • Isolated RS-485*;
    • Modbus slave support (or TCP Master with converter);
  • ISO Spi interface*;
  • support for IO modules (with PWM outputs);
  • Devices can be daisy chained for even more capacity;
  • no limit on inverter support;

With these IO’s the BMS controls your installation in BGTW mode the IO’s are CanBus readable/writable.

The product comes with a PEAK CAN or BUSMUST Interface  Compatible software suite. Consisting of a firmware updater (over CanBus) and a BMS Studio.

The studio permits to configure/test/verify and monitor the installation.

Customer changes and or wishes can be discussed, please contact us :).

Firmware choices**:

  • BlueBMS = Firmware dedicated to vehicles; support for chargers for example;
