What CANOpener talks to

BMS

Battery Management (BMS)

Supports Dilithium, Tesla Classic Model S/X modules, and Zeva. View voltages of all battery cell groups, monitor balancing status, and configure audio alarms for high/low voltage limits.

HV Charger

High Voltage Battery Chargers

Supports Thunderstruck TSM2500 and Elcon CANbus chargers. Monitor real-time charging voltage, charge current commands, and charge state.

Inverter

Motor Controllers

Retrieve live telemetry from your Hyper-9 (SME) motor controller including motor/inverter temperatures, RPM/speeds, and health status. Also supports Kelly and Warp controllers.

Sensor

Current & HV Sensors

Supports LEMCab and Isabellenhütte IVT-S current and high-voltage sensors for real-time Amps, Amp-hours (Ah), Watt-hours (Wh), and accurate State of Charge (SOC) calculations.

GPS

GPS Navigation & Telemetry

Supports AEM GPS units for speed, trip distance, derived driving range, estimated charge completion time, and real-time efficiency metrics.

Wi-Fi & OTA

Web Server & Customization

Includes an integrated Wi-Fi web server for live wireless telemetry on phones or laptops. Software is under active development and can be tailored for your specific vehicle build.
