EV Tech Simplified: Here’s How Power Flows In An Electric Vehicle

Electric vehicles have been rapidly growing and gaining popularity not just in the Indian market, but also worldwide. With more and more EVs turning up on the road, have you wondered how exactly the power and electricity flows through an EV? Well we have the answers for you, so read on.

An electric vehicle setup is rather complex with multiple components playing different but important roles. Now what’s basic here is the fact that the electricity is generated from the battery pack, which goes to the motor, which consequently gets the electric vehicle moving.
For that process to function, there are a bunch of electronic components that facilitate the flow of power and electricity throughout the electric vehicle.

The most important device in the functioning is a motor controller also called the electronic speed controller (ESC) which basically controls and regulates the power flow from the battery pack to the motor in an electric vehicle.

The process involves the motor controller, which has several microcontrollers, receiving control signals from the throttle and braking of the vehicle and delivering the requested amount of power to flow in a timely manner to the motor, consequently achieving a certain speed on the vehicle. For instance, when the brake is applied on an electric vehicle, the throttle input is cut off immediately, consequently getting the vehicle to a halt.

Most of the motor controllers also possess the functionality of regenerative braking. In this phenomenon, the motor controller re-routes the excess power from the motor to the battery pack further recharging it. Bear in mind, that this only occurs when the battery is not fully charged.
Electric vehicles with regenerative braking technology have motors that act as generators when the brakes are applied or when the throttle is let go. During this situation, the power to the motor is cut off. As the motor shaft slows down, this rotational motion is converted into electricity by the generator.
