EV Courses at Portland State

Portland State University has an electric vehicle course sequence. It was developed by Mike Butts and  Dan Hammerstrom. The first course in the sequence, EV1, will be offered this Winter term and the second course, EV2, in the Spring.

Although the primary emphasis is on electric drive, the course is taught as an application of embedded computing. As one of the engineers of the Toyota Prius put it, “It’s all about the software.”

The course uses the Arduino as the primary embedded computing platform:

The sequence also spends time on power electronics and Lithium-ion batteries.

EV1 – Introduction to electric drives and drive control, with emphasis on brushless DC and induction machines, which are the most are relevant to electric vehicles. The topics covered include: switch mode power electronics, brushless DC motors, induction machines, and an introduction to battery technology and management. Laboratory: Matlab/Simulink, experiments with the Power-pole board and a motor workstation based on the Arduino microcontroller.

EV2 – Study of electric vehicle systems. Topics include vehicle dynamics, weight and power trade-offs, electric drives and electronic control, system design, regenerative braking, hybrid drives, and energy storage technologies, including batteries, ultra-capacitors, and fuel cells. There will be an electric bicycle project, involving the design, implementation, and performance analysis of a BLDC/Li-ion drive system. Tasks include selection of motor and drive and energy storage, hardware and software development of Arduino-based controller, charger and BMS, system implementation and measurement.
