Why do Electric Cars Still Use 12-Volt Batteries in 2022?

A A A
12-volt batteries are used in cars to power lights, radios, and other accessories. The car’s engine generates electricity that is sent into the battery by a cable called an alternator. Electric cars don’t have engines generating electricity for their 12-volt batteries—instead, they use motors powered by energy from lithium-ion or nickel-metal hydride batteries. This article will explain why electric cars still need 12-volt batteries even though they don’t need them for propulsion.

What Are 12-Volt Batteries?

A 12-volt battery is an electrical source that stores energy in the form of chemical energy. A standard automotive battery contains six electrochemical cells containing two electrodes (one positive, one negative). Two plates are immersed in sulfuric acid with the cathode plate coated in lead dioxide, and the anode plate consists of porous sponge lead. The chemicals in the battery react, producing electrical energy and lead sulfate. As the battery is discharged, the chemical reaction produces electricity, and when it is charged, it needs electricity to recharge. This chemical reaction takes place inside a 12-volt car battery.
