Joint Component Sizing and Energy Management for Fuel Cell Hybrid Electric Trucks

This paper proposes a cost-effective way to design and operate fuel cell hybrid electric trucks (FCHETs) where chance-constrained optimization is formulated. The aim of the introduced problem minimize summation component cost operational with consideration (FC) degradation cycle life energy buffer. We propose decompose into two sub-problems that are solved by sequential convex programming. delivered power satisfies cumulative distribution function wheel demand, while truck can still traverse driving cycles similar speed travel time without delivering unnecessarily high power. allows downsize powertrain components, including machine, FC A case study considering different buffer technologies, supercapacitor (SC), lithium-ion battery (LiB), capacitor (LiC) investigated in set trucking applications, i.e. urban delivery, regional construction, long-haul. Results show rating machine drastically reduced when satisfied probabilistic sense. Moreover, configuration LiB as has lowest expense but LiC carry more payload.
