Implementation of a Supervisory Control System for an Electric Vehicle

This paper, describes the design and development of a Supervisory Control System (SCS) for an Electric Vehicle (EV) developed by The Applied Electronics Group. The SCS was implemented on a Panel PC, and the Controller Area Network protocol was used as the communication interface with the Traction Controller. This scheme allows implementing the complete control of the EV as two-level architecture, where the SCS works as a high-level controller coordinating the low-level subsystems (traction, batteries, etc.).
