Electric vehicles have been on the market for over a decade, but for most car shoppers it's still a new and unfamiliar technology, and that goes double for the battery packs that power them.
Instead of burning fuel, electric cars rely on a lithium-ion battery pack. Although it may look like a single unit, it's actually made up of thousands of individual cells, all working together to power the electric motor that drives the wheels.
EV batteries are referred to as packs because they typically consist of several battery modules that, in some cases, can contain hundreds of individual cylindrical battery cells that are the same shape as common AA and AAA batteries.
As a fundamental part of any EV or PHEV, the battery pack is a fascinating piece of technology. It can quite possibly be called the heart of an electric vehicle since it provides power to electric motors and determines the range, performance, and energy consumption.
Four main kinds of batteries are used in electric cars: lithium-ion, nickel-metal hydride, lead-acid, and ultracapacitors. Lithium-ion batteries are the most common type of battery used in electric cars. This kind of battery may sound familiar – these batteries are also used in most portable electronics, including cell phones and computers.
