CMC MAX Gateway / BMS / ESS Controller

 369,99 525,49 ex VAT

By using a MAX17841 this device communicates with the Battery Cell Controller IC on the internal module electronics and populates readable data on the CanBus (BGTW firmware). By installing one of the BMS firmwares this device becomes a BMS usable for EV’s or for ESS. (Compatible with several batteries like Hyundai Ioniq & Kona, KIA Niro, Corsa-E and Peugoet e-208 CATL battery modules) contact us to discuss your project needs / wishes.


The CMC MAX is a device from the value-line.
It communicates with slave modules and or batteries equipped with onboard CMC’s. Depending on its firmware it will can help you with communication and or become a BMS.

The data is populated on the CanBus (BGTW Firmware)

  • Cell data;
  • Balancing commands;
  • Temperatures;

By installing the BMS firmware this device becomes a BMS** with the following functions:

  • Contactor control;
  • Charge/Discharge rate;
  • Temperature monitoring;
  • Balance monitoring & control;
  • Charger control*;

The device could carry*:

  • 1 TX/RX port;
  • 2 CanBus interfaces;
  • Digital Inputs;
  • Digital outputs (current sinking);
  • Further IO depends on config:
    • Analog Inputs;
    • PWM outputs (push/pull) low power (optional);
    • LIN BUS (optional);
    • RS-232 (optional);
    • RS-485 (optional);
  • max. 30kw inverter support;

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 test/verify/monitor the installation.

Firmware choices**:

  • BGTW = bare metal CANBus data and commands;
    • For OEM integrators;
  • BlueBMS = basic BMS Firmware;
    • If you don’t need Hybrid Storage inverter communications;
  • ESSBMS = BMS Firmware dedicated to support communications with Hybrid Storage inverters (current list);

Customer changes and or wishes can be discussed :).

* Because of current market conditions configurations of the device may vary; discuss your needs upfront with us.

** This product is continuously improved; expect regular updates which increase functionality.
