TECHNICO-ECONOMIC ASSESSMENT OF BATTERIES FOR ELECTRIC ROAD VEHICLES

This paper is in two parts. In Part 1 an economic analysis is made of the overall operating costs of four electric road vehicles (car, two vans and a truck) and compared with the costs for the equivalent internal combustion engined (ICE) vehicles. It is shown that, at currently projected production rates and costs, electric vehicles are unfavourable unless national ICEV taxes and EV subsidies are taken into account. The cost analysis reveals different characteristics for each of the four vehicles. For the truck, a substantial reduction in battery price or a doubling of its assumed life would make a notable impact on the overall economics. On the other hand, for the smaller vehicles price is relatively unimportant. In Part 2 of the paper an outline design study has been made for an all-solid-state lithium E.V. traction battery based upon an extrapolation of the laboratory results for small-scale cells obtained in the project to date. With a bipolar battery design it is shown that very high energy densities (425 Wh/kg and 500 Wh/1) are potentially attainable at realistic power densities. It is not yet possible to cost such batteries realistically, but preliminary calculations, using the current materials of construction, indicate a materials only cost of proportional pound 30/kWh for the battery modules. To reduce this figure significantly it will be necessary to lower the cost of the lithium salt in the polymer electrolyte and of the intercalation compound in the cathode. An ultimate target of pound 20-25/kWh for the materials cost seems feasible. This analysis focusses the objectives for future research.
