Types of Electric Vehicles:

To meet various driving requirements, there are three different types of electric vehicles. They come in three varieties: all-electric, plug-in hybrid electric, and fuel cell electric.

1. All-Electric Vehicles:

Instead of using gasoline, all-electric vehicles (also known as EVs or BEVs) have a sizable battery that powers one or more electric motors. As new models are released, all-electric vehicle ranges increase from 80 to more than 300 miles. When compared to gas-powered vehicles, all-electric vehicles require less maintenance (such as oil changes, smog checks, spark plug changes, and replacing a catalytic converter or other parts that wear out and break down).

2. Plug-in Hybrid Electric Vehicles:

Plug-in hybrid electric vehicles (PHEVs) provide both gas-only and electric-only driving—even at relatively high speeds. Plug-in hybrids can travel 20 to 55 miles on electricity alone and emit no emissions while doing so, and they do so with smaller batteries than battery electric vehicles. When the car’s electric range is exhausted, it switches to gas and continues to operate as a typical car would.

3. Electric vehicles with fuel cells:

All-electric or plug-in hybrid vehicles use electricity to power their engines, but fuel cell electric vehicles (also known as FCEVs) use electricity differently. Its power system is made up of a stack of numerous cells that chemically combine hydrogen gas from the car’s tank and airborne oxygen to create electricity.

Fuel cells have a driving range of 300–400 miles on a single tank and can be refueled at hydrogen fueling stations, which are more prevalent in California. This process takes about five minutes.

Components of an Electric Vehicle:

Let’s have a look on the components of an Electric Vehicle:

1. Battery (all-electric auxiliary):

The auxiliary battery powers the vehicle’s accessories when it has an electric drive.

2. Charge port:

To charge the traction battery pack, the vehicle can attach to a charging cable using the charge port.

3. DC/DC converter:

The DC/DC converter, which is used to operate the vehicle’s accessories and recharge the auxiliary battery, converts higher-voltage DC power from the traction battery pack into lower-voltage  DC power.

4. Electric traction motor:

The wheels of the vehicle are propelled by an electric traction motor, which draws energy from the traction battery pack. Motor generators that are both drives and regenerators are used by some automobiles.

The traction battery is charged using the onboard charger, which transforms incoming AC power from the charge port into DC power.

5. Onboard charger:

To charge the traction battery, the onboard charger converts incoming AC power from the charge port to DC power.

Additionally, while the pack is being charged, it keeps track of battery characteristics like the voltage, current, temperature, and state of charge by communicating with the charging apparatus.

6. Power electronics controller:

Controlling the electric traction motor’s speed and torque, the power electronics controller regulates the flow of electrical energy supplied by the traction battery.

7. Thermal system (cooling):

This system maintains a safe operating temperature range for the engine, electric motor, power electronics, and other parts.

8. Traction battery pack:

Electricity is stored in the traction battery pack, which the traction motor will use.

9. Electric Transmission:

The electric traction motor drives the wheels by transferring mechanical energy through the transmission.

How does an Electric Vehicle Work?

• The idea behind how electric cars operate is that electric energy is converted into mechanical energy, which is then used to create kinetic energy and permit motion in a vehicle.
• Instead of a traditional internal combustion engine, EVs have an electric motor. Thus, conventional fuel (petrol/diesel) is replaced by electric energy. Electrical energy is converted into mechanical energy by electric motors.
• EVs function like automatic vehicles. Both forward and reverse are options. When an electric car is put into “drive,” it accelerates similarly to an automatic vehicle.
• For the electric motor, power is converted from the DC battery to AC.
• The controller receives a signal from the accelerator pedal and changes the frequency of the AC power from the inverter to the motor to change the speed control of the vehicle.
