Can Hybrid Cars Run On Electricity Only

By | July 31, 2022

A hybrid auto works by utilising both a petrol-powered internal-combustion engine (ICE) and an electric motor that is powered past a battery. There are also diesel hybrid cars, but these are far less mutual – petrol hybrids are like birds, diesel ones are a bit more like dodos.

If the thought “How does an electrical car work?” has ever crossed your mind, the answer is quite unproblematic: they are vehicles that accept a rechargeable battery pack that powers an electrical motor, completely doing away with the demand for fossil fuels and their harmful emissions.

What is a hybrid auto and how hybrid cars work is a tiny chip more complicated.

Hybrid machine technology is usually divided into three primary types: a mild hybrid (likewise known as power-help hybrids and bombardment-assisted hybrid vehicles or BAHVs), a hybrid electrical vehicle (HEV) and a Plug-in Hybrid Electric Vehicle (PHEV).

Each take different-sized battery packs, different ways those battery packs are charged and dissimilar ways in which the Water ice and electrical motor work in conjunction with each other to power the car.

Hybrid engines consist of a traditional ICE and an electric motor powered past a hybrid auto battery, although in a BAHV the onetime is the main source of ability, while the latter is usually used simply when the motorcar is coasting, braking, or stopped.

While some hybrids have an electrical-simply mode, BAHVs exercise not – the electrical motor is only used to mildly assist the car’southward combustion engine and is never relied on fully as the machine’south main source of power.

BAHVs may too employ regenerative braking, a process where kinetic energy that’s created from the car slowing down can either be stored away for later in the battery, or tin be used to power the electric motor direct.

The electric motor in a BAHV is usually mounted between the internal-combustion engine and transmission, taking the place of the torque converter.

A BAHV will reduce your fuel consumption and emissions, but non by a whole lot – you’ll want a HEV or PHEV if y’all desire to make any kind of meaningful difference to the amount of petrol you lot use and the emissions your car creates.


A full hybrid places a bit more emphasis on the use of the bombardment-powered electric motor, meaning both it and the battery itself volition exist a bit larger compared to what you’ll find inside a BAHV.

HEVs make use of regenerative-braking technology to recharge the car’due south battery and power the electric motor, forgoing the need to ever have to plug-in the bombardment to charge it (more than on that later).

There are varieties of HEVs, however, that use the Ice to turn an electrical generator, which tin either recharge the vehicle’s battery or straight power the electric motor.

In an effort to farther reduce emissions, many HEVs (like many cars in general) also use a finish-get-go function where the ICE is shut downwards whenever the motorcar is idle (if y’all’ve ever heard a car’south engine cut out then quickly restart over again while you’re waiting at traffic lights, that’due south what’s going on).

HEVs typically use the Ice as the primary source of power while the battery-powered electric motor acts equally a kind of “power heave” to assist during different driving weather condition, like when the vehicle requires rapid dispatch.

HEVs are becoming increasingly pop due to their ability to reduce emissions and save on fuel costs when compared to traditional ICE vehicles.


These types of hybrids practice exactly what you call up they practice: they plug in to an external electric power source to accuse upwards their bombardment packs, rather than relying on other forms of free energy-generating engineering, similar regenerative braking.

The battery pack and electric motor is typically a much more substantial part of a PHEV, meaning they’re bigger, heavier and take longer to charge compared to the smaller batteries y’all’d find in a HEV or BAHV.

The do good, though, is that the battery offers the PHEV a sizeable range of electric-only running (and thus zero-emission motoring).

This besides reduces the “range anxiety” experienced by EV drivers worried their battery will run out of accuse while they’re in transit, as the petrol engine is e’er there on standby to kick in and take over should the battery go depleted.

PHEVs aren’t completely green, due to the fact they still employ the use of an ICE from time to time, and the electricity they employ can often be generated using harmful fossil fuels.

Renewable, nil-emission electricity generated by ways such as wind power, solar energy or hydroelectricity can likewise be utilised, yet, to further reduce the impact of a PHEV.

The future of hybrids

Hybrid vehicles are expected to keep growing in popularity in the coming years, with hybrid sales projected to go along rising until they peak in 2027 with a global marketplace value of $792 billion.

There’s also a decent gamble that hybrids using lithium-ion batteries volition eventually be superseded past full-electric cars that use a hydrogen fuel cell, simply that applied science is still some years abroad from hitting the consumer market in a meaningful way.
