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.
It's important to remember that a battery does not store electricity, but. rather it stores a series of chemicals, and through a chemical process electricity is. produced. Basically, two different types of lead in an acid mixture react to produce an. electrical pressure called voltage. This electrochemical reaction changes chemical. energy to electrical energy and is the basis for all automotive batteries. This Automotive Series. 12-volt Lead Acid.
