Inside the BMS

Hover or tap a point on the unit to see what sits behind it.

  1. Houses the electronics for the pack. The 72V 200A Premium BMS is designed with a fire-resistant enclosure and automotive-grade components.

    • Fire-resistant design
    • Automotive-grade
  2. High-current MOSFET topology switches the pack, with an intelligent pre-charge circuit that limits inrush into capacitive loads.

    • 120A / 200A continuous
    • Pre-charge
    • Fail-safe disconnect
  3. An STM32 microcontroller runs SOC/SOH estimation, protection logic and the CAN, BLE and RS485 stacks.

    • STM32
    • CAN 2.0B
    • BLE 5.0
    • RS485
  4. Per-cell voltage and temperature measurement feeds active balancing, moving charge between cells to keep the pack uniform.

07 / Fleet intelligence

Every pack in the fleet, in one view.

The Battery Telematics Unit streams cell-level data to the cloud, so operators see state of charge, state of health and temperature per vehicle and act before a fault becomes downtime.

  • Cell-level visibility

    SOC, SOH, voltage and temperature for every pack, refreshed every 1 to 60 seconds as configured.

  • Predictive alerts

    Anomaly detection and degradation trends flag packs before they cost you uptime.

  • Remote diagnostics and OTA

    Inspect a fault and push BMS and telematics firmware without a workshop visit.

  • Open APIs

    REST APIs and MQTT telemetry plug into your fleet-management system or ERP.
