Product Overview
AEM Programmable EV Vehicle Control Unit, Universal, 196-pin connector, 3 CAN, 4-Motor Control, IP67k Aluminum Enclosure
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 motorsports- and conversion-ready features presented in a high feature, modern and customizable interface. Be In Control with AEM EV.
AEM EV's VCU300 is built on OEM hardware and features OEM quality strategies. Combined, these provide the highest level of reliability, and more importantly, safety for both the programmer and end-user.
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.
Primary functions of the AEM VCU300 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 for each inverter system
- 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
The AEM EV VCU300 features a waterproof aluminum enclosure (IP69K, -40C - 105C) and has a 196 pin connector. It is built on OEM hardware with OEM control strategies and uses proprietary AEMcal software for programming.
The VCU300 can control up to four independent electric motors/inverters and link 3 independent controller area networks (CAN bus). A base set of hardware features is shown below. Actual features are application dependent.
