This paper describes a vehicle simulation, originally designed for a hybrid (battery and fuel cell) short urban distances, which can be used to estimate the hybrid vehicle battery, fuel cell and/or hybrid system (both systems working together) range. The simulation model is a function of many mechanical and physical variables that depends not only on the vehicle but also on the ground. It includes the simulation of each of the elements that make up the ecological scooter, so much the driving system whose main element is an electric motor, as the energy storage system whose main element is an acid lead battery fed by a hydrogen fuel cell. An analysis of energy efficiency and operation of the vehicle is made. This Project is framed in a context that seeks an environmentally friendly alternative to current motorcycles in order to reduce polluting emissions, more precisely greenhouse gases, encouraged by the Kyoto Protocol. From simulation environment, some all these tasks can be performed. The application of this numerical model is to help to conceptual design and unit sizing of a real life-service battery, fuel cellhydrogen and hybrid vehicle, and permits to predict the vehicle range and hydrogen and energy consumption. Results of simulations both driving cycles and real routes test are presented. Some aspects as CO2 emission saving, hydrogen consumptions an many other have been considered.

“…It has been found that the bus with a smaller FC and larger energy storage actually surpassed the other bus for most of the degree of hybridisation optimising factors. It has been shown in References [16][17][18][19] that the degree of hybridisation is heavily dependent on the expected duty cycle. In References [8,20,21], it has been found that when selecting the energy storage for the FC hybrid system, SCs are much more effective in shielding batteries from high current loads and can respond quicker to dynamic load when compared with batteries.…”

“…As such, the sizing of a SC based on the acceleration power requirements is not an appropriate method when considering SCs; instead, sizing for the energy storage capacity to meet the energy requirements required to level the load demands is of greater importance. The work presented in References [16][17][18][19] also considers batteries as the energy storage system, although there are similarities between the role of SCs and batteries in a hybrid system the considerations necessary for sizing these components substantially different. In References [8,20,21], FC/SC/battery hybrid systems are proposed, where the implementation of three different systems changes the dynamics of the control strategy and will impact upon the system design and control strategy.…”

Fuel cells (FC) are a clean energy source that are capable of powering a vehicle’s electrical energy requirements whilst providing zero operating emissions. In this study, a full-scaled computer model FC/supercapacitor (SC) hybrid has been developed to investigate the performance of the hybrid propulsion system under real-world performance conditions. A control strategy focused on maintaining a constant FC output at a user-defined value has been developed and applied to the FC/SC hybrid model. Driving cycles collected from a practical double-decker bus have been utilised to evaluate the developed model. It has been demonstrated that the proposed control strategy is capable of maintaining a constant and stable FC output while meeting a real world dynamic load. Based on the obtained results, a general strategy to identify the degree of hybridisation between the FC and the SC in a FC hybrid system has been developed and demonstrated.

“…The secondary energy source is used to enhance the scooter driving range, improve the performance at cold starts, and reduce overall system costs [21]. State-of-the art power system architecture combine PEM FC with lithium batteries [22]. The main advantage of using a battery over supercapacitor is that they provide a larger storage capacity.…”

The need for zero emission drive is a global necessity that can contribute to mitigate greenhouse gas emissions. In this context, fuel cell hybrid electric vehicles are increasingly attracting interest by governments, companies and academia. While parked they can operate as power generation units, given the proper connection to the electricity grid via vehicle-to-grid integration (V2G), or even power appliances directly (Vehicle-to-Load, V2L). In this study, we analysed the use of a hydrogen fuel cell electric scooter in combined driving, V2G and V2L mode. V2G resulted in the most efficient mode of the three, while V2L led to higher degradation rates. The measured average cell voltage degradation rate was 209 mV/h for driving mode, 356 mV/h for V2G and 648 mV/h for V2L. The insights provided in this study are useful to develop new, optimized and specifically targeted energy management systems for power generation of hydrogen hybrid electric drive vehicles.
