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.
A battery stores CHEMICAL energy.    Then, when a circuit is connected to it, the chemical energy is  converted into ELECTRICAL energy (called charge, measured  in â¦coulombs) which is sent around the circuit as a flow  of electric current (called coulombs per second, which  has been given the international unit name ampere).
