Plug-in-Hybrid Electric Vehicle (PHEV) is a type of hybrid EV that combines power sources such as an electric motor and an internal combustion engine (ICE) along with a large battery. The battery can be charged using an electrical outlet. It can also be done using the charging station, by the ICE, or through regenerative braking. When the vehicle brakes, the electric motor works as a generator, using the energy from braking to recharge the battery.
Once the battery is fully charged, the Plug-in-Hybrid Electric Vehicle (PHEV) works on electric power only, and there is no need for gasoline. As the charge starts depleting, the vehicle automatically shifts its function to the hybrid mode where the electric motor and internal combustion engine operate together. If the charge of the battery further drops and gets empty, the PHEV works like a traditional non-plug-in hybrid vehicle and ICE acts as a source of power.
What are the Types of Plug-in-Hybrid Electric Vehicle (PHEV)?
PHEVs can be classified into two types, series, and parallel PHEVs.
1. Series PHEV: Here, the car operates on electric power until the battery charge is depleted. Then the engine supplies power to the electric motor. This type of vehicle may not require conventional fuel during driving at low speeds and short distances.
2. Parallel PHEV: Both the electric motor and engine are connected to the wheels and work together to propel the vehicle forward. If you are driving at a slow speed, electric-only mode is available.
Therefore, Plug-in-Hybrid Electric Vehicle (PHEV) offers the benefits of hybrid cars, including fuel and cost efficiency, and can also operate purely on electric power. There are certain PHEVs that can cover more than 70 miles of electricity. Moreover, during typical driving conditions, PHEVs have the capacity to store adequate electric charge to reduce their dependence on diesel fuel or gasoline. In this way, PHEVs potentially consume less gasoline resulting in significant annual savings.
