What is Hybrid Electric Vehicle ?

What is meant by hybrid electric vehicles?

A hybrid electric vehicle (HEV) is a type of vehicle that uses both an electric engine and a conventional internal combustion engine.

This type of vehicle is considered to have better performance and fuel economy compared to a conventional one.

Definition - What does Hybrid Electric Vehicle (HEV) mean?

Techopedia explains Hybrid Electric Vehicle (HEV)

There are different types of HEVs, namely, series hybrids, parallel hybrids and series-parallel hybrids.

HEVs usually have the following properties:

Auto-start/auto-shutdown - To avoid wasting energy during idle time, the engine of a hybrid electric vehicle automatically shuts down and starts as soon as the accelerator is touched.

Regenerative braking - Considered one of the salient features of HEVs,

the energy wasted during braking and coasting is converted and stored in the battery, which is then used by the electric motor.

Electric motor assist - By helping the engine during passing, accelerating or moving up a hill,

the electric motor allows the engine to be made smaller and more efficient in nature.

An electric car is one that runs on, and is ‘charged up’ with, electric power

The advantages of HEVs include:

Petrol or diesel is never used to refuel an electric car.

Oil consumption is less than that of conventional vehicles.

The electricity that powers an electric car is stored in batteries before being used by electric motors to drive the car’s wheels; the addition of an fossil fuel engine would make it a hybrid.

Carbon-based emission is lower, which makes HEVs more eco-friendly.

Hybrid cars, meanwhile, have electric elements to their powertrains but cannot be considered ‘electric cars’ due to the presence of a petrol engine

This also helps conserve non-renewable resources like petroleum products.

This has caused some confusion recently, not least because certain manufacturers are very keen to describe as "electric" a car which still burns fossil fuels to move; misleading at best, and deceptive at worst.

Maintenance costs are lower than those of conventional vehicles.

Electric cars are becoming commonplace thanks to certain financial advantages, including government grants and the lower cost of “filling up” compared to a tank of petrol.
