The energy storage capacity problem and accumulation of electric power in electric traction unmanned vehicles

Abstract

At present the development of ground vehicles using engine technologies in the automotive industry on the basis of electric drive is actualized to solve the following issues: climate change, improved air quality and reduced dependence on fossil fuels. Along with the support of government agencies for the development and implementation of this type of vehicles, incentives and incentive programs for consumers are introduced, which give an understanding that the production of new types of energy saving machinery will also be global. It is known that the main problem of the spreading of such vehicles is directly related to the system of storage and accumulation of electricity necessary for traffic functioning. The article provides an analytical study of the current ways of accumulating and storing energy in modern vehicles and which are used by various automakers to find out the strengths and weaknesses in them. The chemical composition of the most widespread and actually used lithium-ion storage devices in comparison with a traditional type of fuel - gasoline has been considered. The mass of substances involved in obtaining energy was determined by calculation. An analytical comparison of the energy density per kilogram and the actual price of the energy source for today were given according to information provided by distributors of world manufacturers. The carried out analytical research allowed to reveal the most perspective at present types of storage devices taking into account mass, power consumption and cost. Such information is useful in the design of vehicles while developing energy accumulation and storage systems.
