How Does Electric Vehicles Engine Work ?


An electric vehicle is a vehicle driven by one or more electric motors. Externally, electric cars look exactly like petrol ones. The only thing that emits an electric vehicle during its movement is the almost complete absence of sound when the engine is running. But though, outwardly gasoline and electric cars are very similar, they differ significantly according to the principle of their work. Let’s answer the question “How Does Electric Vehicles Engine Work” more detailed.

Electric Vehicles Engine Work Principles

Under the hood of an electric car, instead of a gasoline engine, an electric motor is installed, which receives power from the batteries. Batteries serve as a fuel tank and provide.

The electric motor provides the energy needed to move the vehicle. The electric vehicle is equipped with an engine control unit, which regulates the currents in the network between the pump and the motor.

All other components in the electric car are practically the same as in the gasoline: gearbox, brakes, airbags, etc.

Electric Motors and Batteries

The electric motor is the heart of an electric vehicle, its main driving force. The principle of electromagnetic induction (the phenomenon associated with the appearance of an electromotive force in a closed loop when the magnetic flux changes) is based on the electric motor. The electric motor provides electricity by converting electrical energy into mechanical energy. The efficiency of a modern electric motor is about 90%.

The main characteristics of the electric motor are power, maximum torque, voltage, current, and speed.

To complete the electric car can use, both electric motors of direct current, and alternating. Each of these engines has its advantages and disadvantages. The DC motor can operate from a power supply of 96V-192V. The AC motor is a three-phase AC motor.

Recently, the use of motor-wheels in electric vehicles has become quite popular. Thanks to the combination of a conventional wheel and an electric motor in one design, a good handling of the vehicle is ensured.

Some AC motors are able to operate in the generator mode when braking the vehicle, thereby generating electrical energy that is stored in the batteries and is then used for vehicle movement (regenerative braking function). The system of regenerative braking allows increasing the range of the electric vehicle’s run up to 15%.

The main sources of energy in electric cars are battery batteries. The relatively high price of batteries is the main reason why gasoline cars still predominate in the world. Reducing the cost of batteries would greatly enhance the popularity of electric transport technologies.
