By 2030, it’s projected that there will be more than 26 million electric vehicles (EVs) in the U.S., according to the Edison Electric Institute (EEI). However, many potential EV drivers have range anxiety and are concerned about being limited by the range of an electric vehicle and insufficient EV charging infrastructure. For this reason, plug-in hybrid electric vehicles (PHEVs) are a popular alternative because they offer some of the same advantages as electric vehicles without the same range of issues.
Because this is a major automotive industry trend, solar and EV charging station installers must understand PHEV meaning and how plug-in hybrids work to help educate potential customers.
PHEV Meaning: What is a Plug-in Hybrid?
A plug-in hybrid electric vehicle (PHEV) is a type of hybrid car that combines a gasoline-powered internal combustion engine with an electric motor and rechargeable battery. The PHEV meaning refers to the ability to plug the vehicle into an external power source, allowing it to charge the battery and drive on electricity before switching to gas.
Unlike conventional hybrids, which rely primarily on the engine and regenerative braking, plug-in hybrids can be charged at home or at public EV charging stations, making them more flexible for short, electric-only trips. This design explains what a PHEV car is and why many drivers see it as a bridge between traditional hybrids and fully electric vehicles.
PHEV Working Principle: How Electricity & Gas Work Together
Understanding the PHEV working principle helps explain how plug-in hybrids balance electric driving with gasoline backup.
Dual Power Sources: PHEVs use both an internal combustion engine and an electric motor powered by a rechargeable battery. The vehicle automatically switches between electricity and gasoline, or combines both, depending on driving conditions. This is central to how a PHEV works.
Electric-Only Range: Most PHEVs can operate on electricity alone for a limited distance, known as the PHEV electric range. This allows many daily trips to be completed with zero tailpipe emissions before the car begins to use gas.
Plug-In Battery Charging: Because a plug-in hybrid can connect to an external power source, drivers can charge a PHEV at home using a standard outlet or a Level 2 charger. Public charging stations also support how plug-in hybrids work in real-world driving.
Regenerative Braking: Like other electrified vehicles, PHEVs use regenerative braking to capture energy during deceleration and convert it into electricity. This improves efficiency and helps recharge the battery while driving.
How Do Plug-In Hybrids Work in Real-World Driving?
Plug-in hybrid electric vehicles use both electricity and gasoline to power the vehicle. A PHEV can drive on electric power alone for a limited range, then automatically switch to gas once the battery is depleted. Drivers who charge consistently can complete many daily trips using electricity, with gasoline available for longer drives.
Plug in hybrid automobile owners often appreciate the ability to charge at home. The most popular options are a Level 1 charger using a standard wall outlet or upgrading to a Level 2 charger with 240 volts. Drivers may also charge their PHEVs using commercial EV charging stations at shopping centers, gas stations, or parking lots. These public charging stations will continue to gain popularity as PHEV adoption increases.
Key Components That Make Plug-In Hybrids Work
Understanding how PHEVs work starts with the systems that manage energy between electricity and gas.
Internal Combustion Engine (ICE): The gasoline engine provides power when the battery charge is low or when additional performance is needed. This ensures the vehicle can travel beyond the electric-only range without relying on charging infrastructure.
Electric Motor: The electric motor powers the vehicle during all-electric driving and can work in tandem with the gasoline engine to improve fuel efficiency. It allows short-distance trips to be powered solely by electricity, reducing fuel consumption.
High-Capacity Battery: The battery stores the electricity that powers the electric motor. Unlike regular hybrids, PHEVs can be plugged in to recharge this battery, providing longer electric-only driving ranges.
Onboard Charger: This component allows you to recharge the battery by plugging into a standard electrical outlet or a dedicated charging station. It’s a key part of how plug-in hybrids work, enabling the electric motor to function independently.
Regenerative Braking System: When you brake or slow down, the regenerative braking system captures the energy that would otherwise be lost and uses it to recharge the battery. This helps maximize efficiency during driving.
Power Electronics Controller: This manages the flow of energy between the battery, the electric motor, and the internal combustion engine. It ensures that power is used efficiently and effectively during different driving conditions.
Is There a Standard Definition of PHEV Meaning?
The PHEV meaning refers to a type of hybrid vehicle with a rechargeable battery that can be plugged into an external power source for additional electric range. While the general concept is standardized, variations in specific features and capabilities among different models may exist, contributing to nuanced interpretations of PHEV meaning in the automotive industry.
PHEVs Explained: Plug-In Hybrids Vs. BEVs and Traditional Hybrids
Not all EVs are created equal. To understand how PHEVs work, let’s distinguish between BEVs, HEVs, and PHEVs.
Plug-In Hybrid Vs. BEV
Battery-electric vehicles (BEVs) run exclusively on electricity and do not have gas tanks or internal combustion engines. Popular models include the Chevy Bolt, Tesla Model Y, Tesla Model 3, Ford Mustang Mach-E, VW ID.4, Kia EV6, Rivian R1T, and the Ford F-150 Lightning.
The most obvious difference between BEVs and PHEVs is that PHEVs offer a gasoline engine as backup when the battery’s electric charge is depleted. This could help quell some range anxiety and offer a more predictable driving experience. However, PHEVs usually have smaller batteries and a shorter all-electric range.
Hybrids Vs. Plug-In Hybrids
HEVs, also called “conventional hybrids,” and PHEVs are very similar, except that PHEVs typically have higher-capacity batteries and charging capabilities. This enables the car to have an electric range that requires no gasoline or fuel. A standard hybrid electric vehicle (HEV) without plug in abilities doesn’t run for significant amounts of time with only electricity, except at very low speeds or when stopped. This hurts the fuel economy of conventional hybrids and causes the car to consume more fuel.
Pros & Cons Of Plug-In Hybrids
PHEVs certainly have their advantages and disadvantages. Let’s explore both.
Pros Of Owning A PHEV
For drivers who charge regularly, hybrid plug ins can significantly reduce their tailpipe emissions and fuel costs. Typically, the more the hybrid runs in electric mode, the greater the fuel savings. Households with solar energy systems can charge their PHEVs with solar electricity.
Many people are concerned about the environment and the impacts of greenhouse gas emissions on climate change. The more the car runs in electric mode, the less air pollution there is. Also, some PHEVs qualify for a federal tax credit of $3,750 to $7,500, making them more affordable to car shoppers.
However, recent policy changes have impacted these incentives. President Trump's executive order, "Unleashing American Energy," has halted the disbursement of unspent funds from the Inflation Reduction Act (IRA), affecting various clean energy initiatives, including tax credits for electric vehicles.
Given the evolving nature of these policies, it's advisable to consult the latest IRS guidelines or a tax professional to determine current eligibility for PHEV tax credits.
Cons For PHEVs
Some drivers may not have convenient access to an EV charger or find charging inconvenient. This is especially problematic for people who live in multi-unit buildings. If a PHEV isn’t charged, the driver will miss out on the advantages, and the car will get similar gas mileage as a typical hybrid vehicle.
PHEVs also typically have larger batteries than HEVs, resulting in higher-cost vehicles. This means some of the battery's capacity will be wasted if it does not run on electricity regularly.
