Mouser takes a look at the use of ruggedized measurement sensors in the designs of EV Formula E racing cars.
Formula E auto racing is not just a favorite spectator sport among auto hobbyists, but as a performance innovation hub, the sport continually contributes to the advancement of battery electric vehicles (BEVs)—or EVs, for short. The electronic systems in EV racers are complex in several ways. Today’s high-end racers contain over 60 embedded semiconductor processors, and when fully instrumented, they also include many sensors, telemetry, and data acquisition components that communicate environmental data. This complex system of components operates in extreme environmental conditions, such as temperature, vibration, pressure, and radiation, which means the system of electronics must have protection while operating at top performance in small spaces.
This article explores the four key types of extreme conditions that EV race car’s experience and how electronic measurement sensors play a role in monitoring and communicating vital data about these conditions. This article will also share design techniques and insights on how to protect these valuable electronic sensors and ultimately improve an EV racer’s overall design, safety, and performance.
