Influence of Battery Technologies on Sizing of Hybrid Fuel Cell Sources For Automotive Applications

The design of the Energy Storage System (ESS) is a very complex task which consists to define the optimum of the weight, volume, cost and ensures as possible longer lifecycle of the whole system. The aim of this paper focuses on studying the influence of battery technologies on the ESS design with tacking into account the auxiliaries' components. Also we confirm via this work that the additional weight of the components increases the power and energy consumption. For this reason, it is necessary to prove that the designed storing system can guarantee the vehicle supply after the integration of the hydrogen tank, fuel cell system and batteries. Furthermore, the effect of the battery's technology on the storage system characteristics is carried out using numerical simulation. The sizing results show that considerable gains have been achieved in terms of cost, weight and volume using Ultra High Power (UHP) technology.
