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.
Batteries. Batteries use a chemical reaction to do work on charge and produce a voltage between their output terminals. The basic element is called an electrochemical cell and makes use of an oxidation/reduction reaction. An electrochemical cell which produces an external current is called a voltaic cell.atteries.
