How do electric cars work? Main components of the electric car – Technical blog in Hindi

Nowadays, due to rising gasoline and methane prices, everyone is looking to electric cars as an alternative. The popularity of electric vehicles is increasing by the day, so let us know how electric vehicles get you from place to place. As electric car production costs decline and charging infrastructure improves, electric vehicles (EVs) are the first people to avoid soaring petrol, diesel and gas prices or to reduce their environmental impact. But how do those electric cars actually work? Let us know!

Electric vehicles (EVs) are a growing industry. The global number of electric vehicles on the road is projected to increase from 8 million in 2019 to 50 million by 2025 and to close to 140 million by 2030. Many large automakers are adapting to selling electric vehicles.

Electric vehicles are similar to petrol and diesel cars. Some models also have non-functional fake grids. But the real difference between electric vehicles and petrol-diesel cars lies under the hood.

parts of electric vehicles

Electric vehicles have no engine, radiator, carburetor or spark plugs. Where there is normally an engine, some electric vehicles have a front trunk. Electric vehicles (EVs) may function differently from conventional vehicles, but they have a similar set of systems.

Key components for electric cars

Exhaust system for electric vehicles (exhaust system for electric vehicles)

Often people or new drivers are curious about how much vibration or noise the electric vehicle makes. This can be measured by the fact that when an electric vehicle stops at an intersection, only the control panel lights up to let drivers know it is still on. With zero tailpipe emissions, electric vehicles help mitigate a major cause of climate change.

Batteries for electric vehicles

Electric vehicle batteries store energy that aids in driving the vehicle. The battery is actually a package of several small lithium-ion battery modules, which in turn are made up of individual battery cells (about the size of an AAA battery). These batteries are linked together in electrical circuits to provide maximum power in the most efficient way.

The battery is one of the most expensive parts of electronic vehicles, so work is done very quickly on battery technology, so as to reduce the cost of the most expensive part of electric vehicles, and the energy density of the battery is also increased.

One danger of lithium-ion batteries is “thermal runaway”, which can cause fires. To prevent this, the battery pack is cooled with a thermal management system and protective casing.

The engine

An engine in an electric vehicle converts electricity into mechanical energy. When electricity is sent from the battery to a stationary part of the motor (stator), it creates a magnetic field that causes the rotating part to rotate.

The rotating rotor creates mechanical energy that uses a gear to spin the car’s wheels. The higher the power, the faster the rotor spins and since there is no shifting between gears in electric vehicles, the transitions between acceleration and deceleration are smooth.

While a petrol or gas car can have only one combustion engine, an electric vehicle can have multiple engines, which operate independently. A dual-motor vehicle has one motor for starting and stopping city driving and the other motor (often called an induction motor) for driving at high speed.

how to drive an electric vehicle

The difference between electric and gas cars affects how they are driven, powered and maintained.


Electric vehicles are known for their rapid acceleration and instant forward propulsion.

Torque is the force that produces rotation in a car’s engine. Since petrol or gasoline engines start at low revs and move through a gear shift, it takes some time for them to reach maximum torque.

While in an electric vehicle, maximum torque is reached immediately by pressing the accelerator. Some electric vehicles have the highest 0-60 acceleration, which is especially useful when entering freeways, crossing slow-moving vehicles, and avoiding accidents.

To brake

When a driver applies the brakes in an electric vehicle, “regenerative braking” draws energy from the movement of the vehicle. This electricity is fed back to the battery, so no energy is wasted.

Driving in regenerative braking mode means that every time you take your foot off the accelerator, the vehicle slows down faster than a petrol or petrol car. Regenerative braking allows for “one-pedal driving”, where the brake pedal is used less.


An electric vehicle, along with most of the large, heavy batteries found at the base of the electric vehicle, will have a lower center of gravity than gasoline-powered cars. This improves its handling when cornering and in slippery road conditions. This makes rollovers less frequent, improving the safety of the car.


Even faster charging electric vehicles gas Or it takes longer than it takes to fill the gas tank. However, 80 percent of electric vehicle charging is done overnight at home, similar to the way we charge a phone, so the charging speed is great for long-distance travel and for those who can’t charge. at home, much more relevant.

Refueling of electric cars

Repair of electric vehicles

Electric vehicle versus a mechanical device computer on wheels (computer on wheels). Like digital device manufacturers, some EV manufacturers send software updates over the air to improve the efficiency of their vehicles or to add new features. This not only prolongs the life of the vehicle, but also reduces its operating costs.

Even when drivers don’t try, electric vehicles continue to improve and become more efficient. This means that electric cars can increase in value over time and improve their stability.

Frequent questions

1. How many types of electric vehicles are there?

There are generally four categories of electric vehicles:

  1. Battery Electric Vehicles (BEVs), which are fully electric;
  2. Hybrid (HEV), plugless cars equipped with batteries and fuel tanks;
  3. Plug-in Hybrid Electric Vehicle (PHEV), the intermediate point between a hybrid vehicle and an electric vehicle;
  4. and hydrogen electric vehicles (fuel cells), unusual vehicles that run on hydrogen.

2. Where can you charge an electric car?

Electric cars can be recharged at home (even using only a standard 120-volt outlet) or at public charging stations.

3. How often do electric cars need to be recharged?

Most electric vehicles can travel 250 to 350 miles on a single charge and need to be charged continuously at 20% to 80%. While many people charge their cars at night, this is too frequent according to some experts who say that too frequent charging can shorten battery life.

4. How long do electric cars last?

Electric cars are so new to the mainstream that it’s hard to tell how long they last. In general, they should last 10 to 20 years.
