Tool for energy storage system synthesis

摘要

An essential part of Hybrid Electric Vehicles (HEVs) and Electric Vehicles (EVs) is the Energy Storage System (ESS). This paper describes a tool, named Tool for Energy Storage System Synthesis (TESSS), that automatically transforms ESS demands to cost-effective ESS design candidates. The following statements characterise the tool: Mathematical modelling and optimisation are essential ingredients. The handled ESS technologies are batteries of various types, supercapacitors and combined ESSs. Combined ESSs include both battery and supercapacitor cells. The optimal design is pointed out by a cost function and requirements. The cost function includes investment cost, wear cost and costs due to energy losses. Examples of requirements are minimal power, maximum package volume and voltage. TESSS is user friendly and extremely computation efficient owing to its compiled C code. To exemplify the practical use of the tool, two case studies are also presented in this paper.
