Come let’s explore hybrid electric cars, such vehicles are driven by an internal combustion engine joint with one or two electric motors that use power via batteries. Mild hybrids—also known as micro hybrids—use a battery as well as an electric motor to provide power to the vehicle and enable the motor to shut off when the vehicle stops, which indeed is very helpful full improving fuel efficiency.

Difference Between Mild Hybrids and Full hybrids EVs
Hybrid electric cars can be either full or mild hybrids, and full HEVs can be designed with series or parallel configurations.

Mild hybrids—also known as micro hybrids these car systems cannot power the whole vehicle by using electricity only. Generally, these cars are less expensive than the full hybrid but come with fewer fuel economy benefits in comparison to full hybrids.

Full hybrids come with more powerful electric motors and bigger batteries, which are able to provide power to the car if you wanted to travel for short distances and at low speeds. Cars are costlier than Mild Hybrids but offer more fuel economy benefits.

Invigorate Braking
Hybrid electric cars don’t require any plug-in charging in their place, the vehicle uses internal combustion and the engine regenerative braking to charge. The vehicle gets power generally lost during braking via the electric motor as a generator and storing the power in the battery.

Are all hybrid cars can be charged by Regenerative Braking? No not all-electric and hybrid vehicles do this, plug-in hybrid models need added energy from an electricity source to recharge larger batteries. 

Environmental Impact of Hybrid Cars

As we all know hybrid cars run on diesel and petrol and have combustion engines, then how these vehicles are better than conventional cars, since these cars also contain electric motors that support the engine, such cars are way more fuel efficient and emit less harmful gases into the environment. 

Nickel–Metal Hydride Batteries Best Suited for HEVs
If we talk about the batteries, Nickel–Metal Hydride Batteries are most suited for the hybrid electric car, as it offers higher durability, low cost, and better safety features than Li-ion batteries. The extensive of these batteries by Toyota Motor Corporation is also supported in the sales of NiMH battery-fitted HEVs.
