Fuel cell vehicle energy management strategy based on the cost of ownership

Abstract

This study presents a novel energy management strategy (EMS) which outperforms the published strategies developed for an international technology challenge, IEEE Vehicular Technology Society (VTS) Motor Vehicles Challenge 2017. The objective of the strategy is to minimise the cost of ownership of a low-power (15 kW) fuel cell (FC)-battery electric vehicle. Both the fuel consumption cost and power sources degradation costs are combined to represent the total cost of ownership. The simple adaptive rule-based strategy optimises the FC operation during low-traction power operation and switches to battery charge-sustaining operation for high traction power operation. This minimises fuel consumption and increases the lifetimes of the FC and of the battery. The strategy is then compared with the EMS of the 2015 Toyota Mirai, and the challenge vehicle model is modified to capture the learnings from the Mirai. Finally, a cost-benefit analysis for a plug-in FC vehicle is considered in order to improve FC lifetimes and to reduce costs for short drive cycles.

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

“…The FC is considered as always in "ON" state and thus the start/stop-cycle-based degradation is ignored. To prevent the FC system operating at relatively low and high power, the state of degradation (SoD) in the baseline model at time instance t is defined as the integration of the degradation rate over time [45], [46]. This is mathematically expressed as…”

The Role of Hydrogen in Achieving Long Term Japanese Energy System Goals

“…Hydrogen, or Fuel Cell Vehicles (FCV), have the potential to provide long term sustainable transport options [15], having the potential to displace conventional gasoline vehicles as their design and efficiency improves over time [16]. Overall cost of ownership is also an important factor as hydrogen competes directly with electrification of the transport sector [17]. Depending on the nature of the national transport sector, hydrogen may be a less efficient option.…”

Fuel cell‐based topologies and multi‐input DC–DC power converters for hybrid electric vehicles: A comprehensive review

“…The FCs are interconnected to the motor via controlled power electronic components [31][32][33]. The key component of FCHEVs is an FC, auxiliary energy source, power electronic converter, and the motor unit [34][35][36][37][38]. A lot of configurations are available to interconnect elements with the energy management scheme [39,40].…”
