AEM EV Has Released Its VCU200 Vehicle Control Unit


AEM EV has released its VCU200 Vehicle Control Unit (PN 30-8000). AEM EV’s VCU200 is built on OEM hardware and features OEM quality strategies to provide the highest level of reliability, and more importantly, safety for both the programmer and end-user.

AEM EV Vehicle Control Units (VCUs) are the missing link for high-performance EV street-conversion and motorsports applications. They allow the calibrator to create customized torque management strategies applicable to a wide range of EV systems and component combinations. They integrate EV systems and unify the tuning experience providing conversion and motorsports-ready features that are presented in a high performance, modern and customizable interface.

The VCU200 in default configuration can manage a single inverter/motor system, communicate with up to four independent CAN bus networks, and it can be used on direct-drive and indirect-drive EV setups. Multiple motor control systems may be possible depending on the application.

Primary functions of the AEM VCU200 include:

  • Input characterization including accelerator pedal, brake switch, PRND switches, and other driver/vehicle inputs
  • Redundancy and arbitration features for all safety-critical inputs
  • Startup and shutdown sequencing of high voltage components, including independent contactor control
  • CAN message translation for BMS, inverter, PDUs, and other CAN accessories
  • Motor torque management dependent on vehicle operating states and other driver-selectable modes
  • Closed-loop motor speed regulation for indirect drive transmission applications
  • Dynamic torque limits that maximize safety and optimize performance
  • Accessory control of cooling pumps, cooling fans, lights and more
  • Diagnostics and fault detection including CAN message timeouts, thermal limits, contactor, and inverter enable cross-checks
  • IP6k7-rated enclosure (dustproof and waterproof)
