Fuel economy evaluation of fuel cell hybrid vehicles based on equivalent fuel consumption

► We present a new fuel economy evaluation method for fuel cell hybrid vehicles. ► The method is related to the Minimum Principle-based optimal control. ► We present a rule-based strategy based on the FCS efficiency characteristic. ► We evaluate the fuel economy of the rule-based strategy in terms of the method. ► We compare the rule-based strategy to the optimal control by the method.
