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.
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.
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-ch
Give your conversion the modern performance of a new electric vehicle. From first-class systems to quality components, Legacy kits have all the essentials you’ll need to transform your vehicle into a sustainable steed.
