Automated vehicles require sensors and computerprocessing that can perceive the surrounding environment andmake real time decisions. These additional electrical loads expandthe auxiliary load profile, therefore reducing the range of an automated electric vehicle compared to a standard electric vehicle.

Furthermore, a fully automated vehicle must be fail-safe fromsensor to vehicle control, thus demanding additional electricalloads due to redundancies in hardware throughout the vehicle.

This paper presents a review of the sensors needed to makea vehicle automated, the power required for these additionalauxiliary loads, and the necessary electrical architectures forincreasing levels of robustness.
