How Do Electric Vehicle (EV) Batteries Work?

What is an Electric Vehicle?

In modern times, electric vehicles (EVs) are an up-and-coming transportation option. So, this may lead many to wonder – what is an electric vehicle? Well, let’s begin with some basic information. Firstly, an electric vehicle, or EV, is an automobile that runs on electric power. Depending on the type, it can be a hybrid or strictly electrical. The hybrid versions use electric motors in combo with a gasoline engine. On the other hand, strictly electrical vehicles use only batteries and electric motors. These vehicles were questionable years ago but are the way of the future. Using only electricity, these cars are faster and more efficient than conventional vehicles. So, moving forward, this knowledge may lead to the next question – how do electric vehicle (EV) batteries work?

How Does the Battery Work?

So, you’re wondering how do electric vehicle (EV) batteries work? Or, maybe you’re not. Either way, let’s take a dive into the concept. The purpose of any battery is to store energy within a chemical compound inside a physical container. Basically, this begins with an elementary particle – the electron. The electron is a charged particle that allows the movement of energy. Electrons allow for the building of voltage potential; hence a charged battery can motion power to the vehicle. As electrons depart, the battery power dissipates until it can no longer operate at the requested level. To charge a battery, simply plug it into the grid using the correct adapter by the manufacturer.

So, how does the battery relate to the electric motor? Well, the battery stores the energy for the electric motor. But it begins with a control scheme. With a full battery, the battery can turn on the controller, which controls power dispersion in the vehicle. The controller determines how much power to send to the electric motor(s), this allows for control of acceleration and velocity of the vehicle. Without the controller, the battery would most likely be sent into full throttle every time the gas pedal is set downwards. So, obviously, a controller allows for proper voltage and current to produce power. Do note, voltage multiplied by current is equal to power. So, an ampere and a volt combine to create a watt of power!

EVs are the Future of Transportation

In the future, EVs will be a normal visual statement on the streets worldwide. A statement of the modern age, of a cleaner future. Obviously, EVs are environmentally friendly, but nothing that exists is free of some type of pollution. For instance, battery production doesn’t help improve the environment, but the lack of gasoline fuel exhaust does. So in the end, the battery’s life and usage will probably outweigh the alternative. Many manufacturers, including Audi, BMW, and Mercedes are working toward electric futures. Either way, hopefully this article helps with an understanding of EVs and their battery operation. In the end, can you now answer the question – how do electric vehicle (EV) batteries work? If not… read again!
