  • EV telemetry

    Speed, RPM, load, torque and GPS position, read from the CAN bus.

  • Battery SoH / SoC

    State of health and charge for each pack, with alerts before a fault becomes a breakdown.

  • Multi-brand gateway

    Connects inverters, battery packs and energy systems from different manufacturers.

  • Analytics & reports

    Energy modeling and scheduled reports for planning.
