What is a Plug-In Hybrid Electric Vehicle?

A PHEV’s power source can largely be stored electricity when traveling in populated areas. For instance, a luminous PHEV operator may travel entirely on electricity to and from work, plug the car in to recharge at nightfall, and be ready for a further all-electric journey the following day. 

The vehicle is powered by the internal combustion engine when the battery is mostly discharged while accelerating quickly, or when there are heavy heating or cooling demands. The converse is also applicable for some large PHEVs; at the job site, energy is used to run auxiliary equipment or control the cabin’s climate.

Plug-In Hybrid Electric Vehicle

A possible solution that utilizes electricity to replace a sizable portion of fleet petroleum usage is Plug-In Hybrid Electric Vehicles (PHEVs). It is an HEV that can refill its fuel cell storage using power from an external source (such as the power system for electricity). 

The car can then operate in a charge-depleting (CD) mode, lowering the system’s state-of-charge (SOC), and replacing the propellant that would have been used otherwise with electricity. The usual liquid fuel used by PHEVs is petroleum (gasoline or petrol), but other options like hydrogen or biofuels are also available.

Types of Plug-In Hybrid Electric Vehicles

There are two different plug-in hybrid setups.

Types of Plug-in Hybrid Electric Vehicles

Series Plug-in Hybrid: In this setup, the vehicle’s only source of propulsion is electricity. As long as the battery charge is sufficient, the car operates entirely electrically. The engine starts the electric motor when the battery is depleted of power. The series plug-in hybrid might not require conventional fuel on short trips and at moderate speeds.

Parallel Plug-in Hybrid: In this configuration, the car is propelled in practically all situations by both its internal combustion engine and electric motor. Usually, only at slower speeds can the car run entirely on electricity.

Components of Plug-In Hybrid Electric Vehicle

The essential components of a Plug-in Hybrid Electric Vehicle are listed below.

Working principle of Plug-in Hybrid Electric Vehicles

PHEV vehicles work in the same way as conventional hybrid vehicles generally. The bigger battery pack that has to be connected to an external electrical source, is the primary distinction.

Advantages of PHEV

The following are some of the PHEV benefits.

Disadvantages of PHEV

Plug-in Hybrid Electric Vehicles have the following drawbacks.


Mode of Operation The vehicle is propelled by a combination of an IC engine and an electric motor. An electric motor helps the traditional Internal combustion engine run more efficiently or function better. The car is driven by an electric motor.
Emission levels Compared to gasoline and diesel automobiles, they emit fewer greenhouse gases. Lesser carbon footprints than those of traditional cars. There are no pollutants from their tailpipes.
Charging The recharging period is less since battery packs are more compact. There is no requirement for recharging because the battery pack is charged while the car is moving due to regenerative braking or a generator. Battery packs in BEVs are bigger. Thus, the charging time extends.
Price High Low Low

Top Plug-In Hybrid Electric Vehicles

The Top PHEV list here:

  1. Tesla Model Y
  2. Renault Zone
  3. BMW i3
  4. BYD Tang
  5. Tesla Model 3
  6. Chery eQ
  7. BYD Qin
  8. BAIC EU-Series
  9. Tesla Model X


Reduced carbon emissions are one of the significant advantages of PHEVs. Plug-in hybrids significantly reduce vehicle pollution because automotive emissions are the main cause of the rising pollution levels. 

PHEVs can operate in purely electric mode with no emissions when their battery packs are larger. Additionally, the car’s carbon emissions are greatly reduced while operating in hybrid mode.

In general, PHEVs are the subsequent right approach after EVs to reduce car emissions.
