Parallel hybrid operation connects the engine and the electric motor to the wheels through mechanical coupling. Some PHEVs use transmissions that allow them to operate in either parallel or series configurations, switching between the two based on the drive profile. The two main configurations are parallel and series. Fuel-Efficient System Designīeyond battery storage and motor power, there are various ways to combine the power from the electric motor and the engine. Therefore, consistently charging the vehicle is the best way to maximize the electric benefits. If the vehicle is driven a shorter distance than its all-electric range and plugged in to charge between trips, it may be possible to use only electric power. For example, if the vehicle is never plugged in to charge, fuel economy will be about the same as a similarly sized hybrid electric vehicle. PHEV fuel consumption depends on the distance driven between battery charges. During braking, the electric motor acts as a generator, using the energy to charge the battery, thereby recapturing energy that would have been lost. PHEV batteries can be charged by an outside electric power source, by the internal combustion engine, or through regenerative braking. Some heavy-duty PHEVs work the opposite way, with the internal combustion engine used for driving to and from a job site and electricity used to power the vehicle's auxiliary equipment or control the cab's climate while at the job site. The internal combustion engine powers the vehicle when the battery is mostly depleted, during rapid acceleration, or when intensive heating or air conditioning loads are present. For example, a light-duty PHEV driver might drive to and from work on all-electric power, plug the vehicle in to charge at night, and be ready for another all-electric commute the next day. This makes it possible to drive moderate distances using just electricity (about 15 to 60-plus miles in current models), commonly referred to as the "electric range" of the vehicle.ĭuring urban driving, most of a PHEV's power can come from stored electricity. PHEVs generally have larger battery packs than hybrid electric vehicles. PHEVs have an internal combustion engine and an electric motor, which uses energy stored in batteries. Powered by Electric Motor and Combustion Engine Although PHEVs are generally more expensive than similar conventional and hybrid vehicles, some cost can be recovered through fuel savings, a federal tax credit, or state incentives. Medium- and heavy-duty vehicles can also be converted to PHEVs. There are several light-duty PHEVs commercially available, and medium-duty vehicles are now entering the market. PHEVs may also produce lower levels of emissions, depending on the electricity source and how often the vehicle is operated in all-electric mode. Using electricity from the grid to run the vehicle some or all of the time reduces operating costs and fuel use, relative to conventional vehicles. PHEVs can charge their batteries through charging equipment and regenerative braking. Plug-in hybrid electric vehicles (PHEVs) use batteries to power an electric motor, as well as another fuel, such as gasoline or diesel, to power an internal combustion engine or other propulsion source.
