11.5 Hybrid and Electric Vehicles

Today, many vehicles use electricity in addition to or instead of gasoline. These vehicles are designed to improve fuel efficiency, reduce emissions, and lower operating costs. The three main types are hybrid vehicles, plug-in hybrid vehicles, and electric vehicles.

Hybrid Vehicles

A hybrid vehicle uses both a gasoline-powered internal combustion engine and an electric battery. The battery helps power the vehicle, but a hybrid cannot be plugged in to charge. Instead, the battery is recharged through regenerative braking and by the engine during normal driving.

Regenerative braking is a system that captures some of the energy normally lost when the vehicle slows down and sends that energy back to the battery. Because the battery helps the engine, the vehicle uses less gasoline than a traditional gasoline-powered vehicle. This makes hybrid vehicles more fuel-efficient than standard internal combustion engine vehicles.

Plug-In- Hybrid Vehicles

A plug-in hybrid electric vehicle, or PHEV, also uses both a gasoline engine and an electric battery. However, a PHEV has a larger battery than a standard hybrid. This allows the vehicle to drive on electricity alone for a limited distance, usually about 10 to 30 miles, before the gasoline engine is needed.

Unlike a regular hybrid, a plug-in hybrid can be charged by plugging it into an electrical outlet or charging station. This makes PHEVs a good choice for drivers with short daily commutes, especially if the commute is within the vehicle’s electric-only range. For longer trips, the gasoline engine provides flexibility because the driver can refuel at a gas station as usual.

Electric Vehicles

Electric vehicles (EVs) run entirely on electricity. They do not have a gasoline engine, and they produce no tailpipe emissions because there is no combustion happening in the vehicle.  Because electric vehicles convert electrical energy directly to mechanical energy to turn the wheels, the are more efficient than internal combustion engines.  EVs are recharged by plugging them into the electrical grid.

Because electric vehicles have fewer moving parts than traditional gasoline-powered vehicles, they usually require less maintenance. For example, they do not need oil changes and have fewer engine-related parts that can wear out. However, EVs are often heavier than gasoline vehicles because of their large battery packs.

The Alternative Fuel Data Center provides helpful information about how hybrid vehicles, plug-in hybrid electric vehicles (PHEVs), and electric vehicles (EVs) work. Explore the site to learn about the main parts and systems in each type of vehicle.

Visit: The U.S. Department of Energy page How Do Plug-In Hybrid Electric Cars Work?

As you explore, look for: the battery, the electric motor, the gasoline engine, the fuel tank and the charging port.

Think about how these parts are needed in a hybrid, a plug-in hybrid, and an electric vehicle.

Where is the nearest EV fueling station to you? 

Many EV drivers experience range anxiety, especially on long trips. Range anxiety is the worry that the vehicle may run low on battery power before reaching a charging station, or that a charger may not be available or working.

To help with this, drivers can use apps and websites to find charging stations and plan their routes.

Use the Department of Energy Alternative Fueling Station Locator to find the nearest charging station or fast charger:

You can also use PlugShare’s Trip Planner to map out a road trip and see whether the trip could be completed in an electric vehicle:
