Legislation influence and raising environmental awareness lead to significant growth in demand for zero emission buses . Among the newly registered eco-friendly public transportation vehicles the electric buses have the largest market share. Public Transport Operators are looking for the vehicles being able to meet the transportation system requirements with the lowest possible cost of ownership. Batteries used in the electric buses are the most expensive component both in terms of buying and their replacement. In order to maximize the battery lifespan it is crucial to maintain the proper temperature of the electrochemical cells. The crucial part responsible for transfering the heat between cells and the coolant is a heat exchanger. The standard method applied for a cold plate design is to use metal alloys, however due to research it may be not the most advantageous solution. Based on the research works conducted by Solaris Bus & Coach S.A., the specific polymers being able to replace metal alloys for heat exchangers purposes were selected. In this paper the authors will present the results of study allowing the usage of polymer materials for lightweight and cost-effective cold plates.
