Abstract

Refueling control techniques for a fuel cell electrified vehicle (FCEV) involve providing an electrified vehicle control unit (EVCU), a fuel cell propulsion system (FCPS), and a controller area network (CAN) therebetween, providing a set of hardwire wakeup lines connecting from the EVCU to each of the FCPS and other primary modules, and configuring the FCPS to act as a primary controller during refueling operations of the FCEV where a fuel is provided to the FCEV via a fuel hose and a fuel supply system. The EVCU is configured to act as a secondary controller during the refueling operations such that it and the other modules connected via the set of hardwire wakeup lines are able to transition to an asleep state to save low voltage power during the refueling operation.
