This video explores the mechanics of EV batteries, explaining energy storage and transfer processes, the types of EV batteries, and how they power electric motors. It also discusses the science behind battery efficiency and performance.

The driving force behind an electric vehicle is its battery pack. The battery pack in an EV sends electricity to a controller, which runs the car's electric motor or motors. The battery is made up of electrochemical cells with negative and positive electrodes. When the negative and positive electrodes are connected, the negative electrodes flow to the positive side. This flow is electricity. As this process slows down, the voltage produced by the battery drops. Thankfully, EV batteries are rechargeable. There are 3 different kinds of batteries used in today's hybrid and electric cars. Lead-acid batteries are the oldest form of rechargeable battery that are still on the market. The name comes from the combination of lead electrodes and acid that is used to generate electricity. They're used in EVs only to power secondary features, like the infotainment system or driver assistance features. Nickel metal hydride batteries have a much longer life than lead-acid batteries and are widely used in hybrid and plug-in hybrid vehicles. They're easy to recycle because they don't contain toxic metals. Lithium-ion batteries hold their charge longer. They are expensive and require proper handling when being recycled, but their capacity and power output make them the battery of choice for electric cars. Lithium-ion batteries are easy to recharge and are extremely durable. If treated properly, they can often last longer than the car itself. Thanks for watching.
