“…Before a component sizing exercise can take place, the designers must first determine which components will be used in the hybrid powertrain. Although it is possible to use a fuel cell as the sole power source on the vehicle, hybridisation with batteries is much more common [16][17][18][19][20][21][22][23][24][25][26][27]. This allows transient loading to be absorbed by the battery, increasing the lifetime of the fuel cell, and allowing it to operate more efficiently [28][29][30].…”

The size of the fuel cell and battery of a Fuel Cell Hybrid Electric Vehicle (FCHEV) will heavily affect the overall performance of the vehicle, its fuel economy, driveability, and the rates of fuel cell degradation observed. An undersized fuel cell may experience accelerated ageing of the fuel cell membrane and catalyst due to excessive heat and transient loading. This work describes a multi-objective design exploration exercise of fuel cell size and battery capacity comparing hydrogen fuel consumption, fuel cell lifetime, vehicle mass and running cost. For each system design considered, an individually optimised Energy Management Strategy (EMS) has been generated using Stochastic Dynamic Programming (SDP) in order to prevent bias to the results due to the control strategy. It has been found that the objectives of fuel efficiency, lifetime and running cost are largely complimentary, but degradation and running costs are much more sensitive to design changes than fuel efficiency and therefore should be included in any optimisation. Additionally, due to the expense of the fuel cell, combined with the dominating effect of start/stop cycling degradation, the optimal design from an overall running cost perspective is slightly downsized from one which is optimised purely for high efficiency.

“…In recent years, severe energy shortage and environmental pollution has prompted researchers to focus on how to improve the efficiency of construction machinery and exhaust emissions . Especially, with the rapid development of the whole electric car, if construction machinery can use the similar structure, the efficiency of construction machinery can be improved greatly and the emission of conventional internal combustion engine may disappear completely.…”

In this paper, a new type Electric Hydraulic Actuator(New EHA) adopted variable displacement pump is presented to enhance the dynamic response of EHA. This system combines the advantages of electric with hydraulic systems and it is easy to be integrated with the whole electric system, which is a promising tendency to save energy and enhance control performance. Firstly, the basic principle and the difference with the traditional EHA are introduced. Moreover, the mathematical model is constructed. Then, the controller by using the fuzzy algorithm is designed. Finally, the simulation and experiment for the New EHA are investigated, both of the results show the effectiveness of the New EHA.

“…In addition, the CO tolerance of HT‐PEM means that they can be used in conjunction with hydrocarbon fuel reformers without complex gas clean‐up procedures, thus increasing the feasibility of the use of hydrocarbon fuels on board fuel cell vehicles. Despite the advantages of HT‐PEM, there is little evidence describing their use in vehicles; previous reports are limited 2–5. HT‐PEM, is not as advanced a technology as LT‐PEM, has been run for fewer operating hours, and there are fewer manufacturers making them.…”

High temperature polymer electrolyte membrane (HT-PEM) fuel cells offer some advantages over their low temperature equivalent, but there have been relatively few reports into their use in vehicles. This paper describes the power train design and operation of a fleet of Microcab H2EV vehicles. The power train consisted of a HT-PEM fuel cell coupled via a DC/DC convertor to a lithium iron phosphate traction battery, which was then connected to two Lynch motors. The integration and operation of all the major power train components is described. Also described here is the vehicle control unit that uses digital and analog communications to provide overall management of the vehicle. Details are given of all the safety systems designed into the vehicle. Some data describing the performance of the H2EV power-train during typical drive cycles is presented, which shows that the system was functional. It is concluded that HT-PEM fuel cell light vehicles are viable, but the heating and cooling time of the fuel cell needs to be significantly reduced.
