An electric car has a very simple setup than a combustible engine car. There are only a handful of primary components that make an electric car run. If you want to get into the electric car industry, take a quick look:


Here is what a car actually is:


Its a box of seats that run on wheels. Now to run a car on wheels, earliest people used muscle power by getting cars towed by horses and bulls. Then combustion engine was invented which used blasts to turn the wheels.


Then Elon Musk arrived and we all know what happened. The electric car industry was revolutionized. His brand Tesla sells the most technologically enhanced and some of the most expensive electric cars in the world right now. Everyone knows this guy. Why?

Because he not only took a giant step towards lowering the carbon emission by making electric cars fashionable, but also made a very popular business out of it.


Now if you think that you should get into the electric car industry because that is the future, or you would like to do your due part saving mother Earth, let me show you the way. I am going to explain everything you'd ever like to know about electric vehicles, beginning from how they work, and the innovations in the respective industry.


So coming back the main topic, here are the components of an electric car...


  1. Traction battery pack (TBP): This is the pack of Li-on batteries that stores Direct Current which you need to run your car.

  2. Inverter: This device converts DC stored in the traction batteries into AC which is used by the traction motor to run your car.

  3. Controller: Much like an accelerator, this determines the amount of DC to supply from the TBP to the inverter and finally to the motor.

  4. Traction motor: This motor gets supplied with AC from the inverter. This motor is connected to the transmission which is connected to the wheels making the wheels move. Traction motor converts Electrical energy into mechanical energy.

  5. Transmission: This is the gearbox which is connected to the wheels. The traction motor is not connected to the wheels directly, but via the transmission.

  6. Power socket: This supplies traction battery with AC which gets converted with the help of the inverter and gets stored in the traction battery pack as DC.

  7. Thermal system: This is needed to cool the components such as the TBP, traction motor etc.

  8. Additional battery: Battery which stores DC to supply to the accessories of the car.

Here the the pictures of the components you can quickly see. (link)
