Most people have heard about electric vehicles yet few truly understand how they work. Electric vehicles are extremely efficient machines that consume minimal energy. Instead of relying on fossil fuels for propulsion, electric vehicles make use of electricity and storing energy in a set of batteries. Batteries power the vehicle’s motion and auxiliary systems, like lights and windshield wipers. Electric vehicles look exactly like traditional vehicles except there is no exhaust system or gas tank. The battery pack is typically located beneath the vehicle or in its trunk.
Electric Vehicle Power
The three primary components of electric vehicles are the battery, electric motor and controller. When the vehicle is turned on, the electric current moves from the battery to power the electric motor. Electric vehicles also feature links between the controller and accelerator known as variable potentiometers. These devices communicate with the controller, telling it exactly how much power it should supply. When the accelerator is pressed in-full, maximum power is provided. Zero volts are delivered when the accelerator is released.
The engineers who designed electric vehicles should be applauded for incorporating regenerative braking. This term refers to the charging of the electric vehicle’s battery when the driver presses the brakes. This phenomenon occurs as a result of the forward momentum created when the vehicle moves. This energy is redirected to the battery when the brakes are pressed, allowing the vehicle to recoup some of the energy used during the acceleration process.
Electric Vehicle Charging
Many people think the electric vehicle charging process is an onerous ordeal. Charging an electric vehicle is just like charging any other electronic device, except on a larger scale. Electric vehicles are charged with a special charging cable that delivers between 120 volts and 240 volts of current, depending on the type of home charging system used. The actual charging takes place at the driver’s home charging space or a public charging station. Here’s how it works: An electric current moves to the charger. Once the current reaches the charger, it is converted into a format that the vehicle’s battery can absorb and current is transferred to the battery where it is stored for future use.
