How does an electric car work?

As the name suggests, an electric car works with an electric motor and no longer with an internal combustion engine.Electromotes are today in all domestic halk machines and nothing new: washing machine, dryer, hair dryer, mixer….all have electric motors.

Especially with the mobile motors, which are independent of the power grid, the biggest problem was (and is ) to provide sufficient electricity and to get it again.As a result, nupt-independent engines have long been quite “powerless,” they consume too much electricity.

Effizeintere Motofen and powerful batteries, however, have brought about a change.

The graph shows the different components of the electric and internal combustion engine cars and shows significant differences.

The three main components of an electric car are:

  • Electric motor

An electric motor converts electrical energy into mechanical energy (movement). This requires the force of a magnetic field.

This occurs as soon as electric current flows through a conductor (such as a wire). When current flows through the coil, the rotor becomes an electromag- net. Due to the interaction with the magnetic field of the stator, the electromagnet begins to rotate.

The electric motor has a much higher efficiency than a conventional internal combustion engine.For this reason, driving accounts for a much higher proportion of the energy spent in the electric car than in the internal combustion engine.

The principle of energy recovery is making the electric car even more efficient.Braking produces kinetic energy, which is converted into electrical energy in the electric motor instead of as heat. This principle is also called recuperation.

There are different types of electric motors that are used:

In the Tesla, a three-phase asynchronous machine (three-phase induction machine) is a three-phase machine in which the rotor (also runner) runs the rotary field of the stator as a generator and as an electric motor.Three-phase current is a special form of alternating current.

  • Controller

They convert the direct current of the batteries and the usable current around us acts as a medium between the motor and the batteries and ensures that enough energy arrives on the motor.Between the controller and the accelerator pedal, some stzeur elements are installed. These give the controller information about how much energy it needs to release. If the accelerator pedal is not actuated, there is also no energy flow or Flow. When actuated, however, adequate electricity is released.

  • batteries/batteries.

An electric car draws its energy from a rechargeable battery installed in the car.However, these batteries not only supply the engine with the required power, but also all other electronic elements of the car.

A battery (mulator) is a rechargeable battery that chemically stores energy and is rechargeable.In modern electric vehicles, lithium-ion batteries are used for energy storage. A single cell of a lithium-ion battery delivers a voltage of almost four volts. Electric cars can currently be operated with these batteries:

Lithium-ion battery

Lithium-ion batteries provide good performance and a high range, making them more expensive.They are lighter and conduct lead lead lead lead lead to lead to lead icleas as well as nickel-metal hydride. Smartphones or digital cameras are also operated with the same type of battery.

Lead acid battery

This type of batteries is the most popular and cheapest.A big advantage is that they are 97 percent recyclable.

Nickel-metal hydride batteries

They cost far more than lead acid batteries, but offer significantly more power overall.

The Tesla Model 3 uses the latest generation of lithium-ion cells, which the automaker manufactures together with a Japanese manufacturer.

In the case of an electric car, it makes sense to have all the wheels driven by an electric motor.

Conventional all-wheel drives require complex mechanical connections to distribute the driving force from the engine to the four wheels.This is easier to represent with the electromor: MAn takes several small motots and brings them to the axes.

The dual-engine disdriver, which works with two motors, controls the torque on the front and rear wheels separately.

On the video it is also explained very well.
