Propulsion and battery electronics carry a safety argument as well as a performance one. The interesting work is usually in the fault paths rather than the nominal case.
What this usually involves
- Sensorless BLDC and field-oriented control for propulsion
- ESC design, including the protection that decides what happens when a phase shorts
- Battery management, cell balancing and the thermal behaviour that governs both
- CAN and LIN integration into a vehicle network you do not control
