A battery is a device that converts chemical energy into electrical energy and vice versa. batteries for hybrid, plug-in hybrid, and electric vehicles. specifications used to characterize battery nominal and maximum characteristics. pack that consists of individual modules and cells organized in series and parallel.
âA battery is a device that is able to store electrical energy in the form of chemical energy, and convert that energy into electricity,â says Antoine Allanore, a postdoctoral associate at MITâs Department of Materials Science and Engineering ..You cannot catch and store electricity, but you can store electrical energy in the chemicals inside a battery.â. There are three main components of a battery: two terminals made of different chemicals (typically metals), the anode and the cathode; and the electrolyte, which separates these terminals.
