The VCU300 can manage up to four inverter/motor systems, communicate with three independent CAN bus networks, and it can be used on direct-drive and indirect-drive EV setups. Please refer to the Supported Applications Tab for supported Motors, Inverters Battery Management Systems (BMS) and other EV devices.

• Accessory control of cooling pumps, cooling fans, lights and more
• CAN message translation for BMS, inverter, PDUs, and other CAN accessories
• Closed-loop motor speed regulation for indirect drive transmission applications
• Diagnostics and fault detection including CAN message timeouts, thermal limits, contactor, and inverter enable cross-checks
• Dynamic torque limits that maximize safety and optimize performance
• Input characterization including accelerator pedal, brake switch, PRND switches, and other driver/vehicle inputs
• Motor torque management dependent on vehicle operating states and other driver-selectable modes
• Primary functions of the AEM VCU300 include:
• Redundancy and arbitration features for all safety-critical inputs
• Startup and shutdown sequencing of high voltage components, including independent contactor control for each inverter system
