PHEV Meaning: How Plug In Hybrids Work

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 is a type of hybrid vehicle that combines an internal combustion engine with an electric propulsion system. PHEVs are set apart from traditional hybrids because they can be plugged into an external power source to charge their electric battery.

PHEVs Explained

Dual Power Sources: PHEVs have both an internal combustion engine (typically fueled by gasoline or diesel) and an electric motor powered by a rechargeable battery.

Electric-Only Range: PHEVs can operate on electric power alone for a certain distance, depending on their battery capacity. This electric-only range allows for zero-emission driving during short trips.

Plug In Battery Charging: PHEVs can be charged by connecting to an external power source, such as a standard electrical outlet or an EV charging station. This allows drivers to charge the battery and use electric power for some driving.

Regenerative Braking: Like other electric vehicles, PHEVs often utilize regenerative braking, where energy generated during braking is captured and used to recharge the battery.

How Do Plug In Hybrids Work?

PHEVs operate using both an electric motor and a gasoline engine. They can drive a set distance on electric power alone before switching to gasoline once the battery is depleted. Drivers who charge regularly—at home or on the go—may rely mostly on electricity for daily trips.

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.

Here's a more detailed breakdown of the key components unique to how plug-in hybrids work:

Internal Combustion Engine (ICE): This traditional gasoline engine kicks in when the battery's charge is low or during high-demand driving situations. It allows the vehicle to extend its range beyond what the electric motor alone can achieve.
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. Other Electric Cars?

Not all EVs are created equal. To understand how PHEVs work, let’s distinguish between BEVs, HEVs, and PHEVs.

BEV Vs. PHEV

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.

FAQs on How Plug In Hybrids Work & PHEV Meaning

This section answers frequently asked questions about how plug in hybrids work, including their key features, benefits, and differences from other vehicle types.

What does PHEV mean in cars?

PHEV stands for plug-in hybrid electric vehicle. This type of vehicle features both an internal combustion engine and a rechargeable battery that can be charged from an external power source. PHEV meaning includes the ability to drive on electric power alone for a limited range before switching to gasoline or combining both for optimal efficiency.

How Long Does It Take To Charge a PHEV?

The charging time for a PHEV depends on several factors, including the battery pack capacity, the battery's current charge state, and the charging infrastructure.

Level 1 Charging (120V): This is the slowest charging method and typically uses a standard household outlet. Charging times can vary, but it may take around 8 to 12 hours to charge a fully depleted PHEV battery fully.
Level 2 Charging (240V): This is a faster charging option, often found at public charging stations or installed at home. Charging times for Level 2 can range from 1.5 to 3 hours, depending on the PHEV's battery capacity and the current charge level.
Level 3 Charging (DC Fast Charging): Many PHEVs do not support Level 3 charging, but for those that do, it can significantly reduce charging times. If a PHEV is compatible with the fast-charging infrastructure, Level 3 charging can charge it in just minutes.

Do PHEVs Require Special Maintenance?

PHEVs share many maintenance needs with conventional vehicles but also require attention to their electric components. Routine service should include engine upkeep, battery health checks, and software updates. Proper maintenance ensures both the gasoline engine and electric motor function efficiently for long-term performance.

How Does the Regenerative Braking System Work in a PHEV?

The regenerative braking system in a PHEV captures kinetic energy while braking and converts it into electricity, which is then stored in the vehicle’s battery. This process is integral to how a plug in hybrid works, as it enhances overall efficiency by replenishing the battery and extending the electric-only driving range. By recovering energy that would otherwise be lost, regenerative braking contributes to better fuel economy and reduced greenhouse emissions.

How Do PHEVs Protect The Environment?

Because PHEVs may often run from just the electric motor, they can significantly reduce tailpipe emissions. This means drivers won’t need to fill up as regularly either. However, the exact reduction in emissions depends on how frequently the car runs in electric mode.

If the driver never charges the car, it will emit a similar amount as an HEV without plug in abilities. However, when charged regularly with clean electricity, PHEVs can significantly reduce greenhouse gas emissions.

Keep in mind that the environmental impact of the PHEV depends on the power source for the electricity. For example, the positive effect diminishes if the electricity is generated from a coal power plant. On the other hand, charging a PHEV with wind or solar power significantly reduces carbon emissions. Also, to decrease the vehicle's environmental impact at the end of its lifespan, it’s important to recycle as many components as possible, including lithium-ion car batteries.
