Optimal Power Distribution of Fuel Cell Electric Trucks via Convex Programming

This article develops optimal power distribution strategies for the fuel cell electric truck. Based on the power system models of the non-plugin fuel cell electric trucks, a convex programming problem is formulated to optimize the power management between a fuel cell system and a battery pack. At the same time, the power following and thermostat control strategy for the fuel cell electric truck, is implemented. The hydrogen consumptions are systematically investigated under the China heavy-duty commercial vehicle test cycle and the China-world transient vehicle cycle. Finally, based on the developed control strategy, we examine the power distribution of the fuel cell electric truck under different drive cycles.
