Energy Management Strategy of Fuel Cell Electric Vehicles Using Model-Based Reinforcement Learning With Data-Driven Model Update

Fuel cell electric vehicles use fuel cells as their main power source; the vehicle is driven by an electric motor, and have an electric battery as a secondary power source that stores regenerative braking energy and assists driving. To reduce the hydrogen fuel consumption by using these fuel cells a...
