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.
When the battery powers an appliance, the electricity converts back into work as heat, light, sound or rotation of a motor. Solar cells convert light energy into electricity, and dynamos/generators convert mechanical energy into electricity. Batteries convert chemical energy into electricity.Converting energy into electricity requires the ability to use simple tools, and a basic understanding of mechanics.hen the battery powers an appliance, the electricity converts back into work as heat, light, sound or rotation of a motor.
