POWER SINK CONTROL SYSTEM FOR A VEHICLE

A control system for a vehicle includes data processing hardware and memory hardware in communication with the data processing hardware. The memory hardware stores instructions that when executed on the data processing hardware cause the data processing hardware to perform operations. The operations include receiving, at a propulsion controller, power generation, comparing, via the propulsion controller, battery data with a state of charge threshold, and executing, based on the comparison of the battery data, a power sink protocol including at least one mode control via a fuel cell system. The operations also include generating, based on the at least one mode control, at least one of a compressor command and a valve command via an airflow system and regulating, via the at least one generated compressor command and the valve command, an airflow of the airflow system.
