As a DIY queen and budget build expert, I’m often asked about the different types of hybrid vehicles on the market. But what exactly are hybrids, and how do they work? In this article, we’ll break down the basics of hybrid technology and explore the different types of hybrids available.
Parallel Hybrids
Parallel hybrids are the most common type of hybrid vehicle. They use both an engine and an electric motor to power the wheels, together or separately. Toyota’s system, first introduced in a Japan-market Prius in 1997, uses two motors between the engine and front wheels, powered by a small battery pack. The “power split” part of the description means both sources come together to provide a single torque output to the wheels. Under light loads, at lower speeds, one or both motors can power the vehicle while the engine is off.
Series Hybrids
Series hybrids are simpler in concept. Whenever more power is needed than the battery can supply, a gasoline engine switches on to power a generator that recharges the pack. The key here is that the engine torque only powers the generator. It’s not mechanically connected to the wheels, which are powered only by electric motors. This setup is best at steady vehicle speeds, where the engine can operate most efficiently at preset engine speeds.
Plug-In Hybrids (PHEVs)
Plug-in hybrids (PHEVs) are a type of hybrid that can be charged from the grid. They have a larger battery that can be plugged in to recharge, allowing them to operate as an electric vehicle for some distance. The EPA range estimates for PHEVs go from as few as 7 miles to as many as 51 miles. Chevrolet popularized the plug-in hybrid concept with its 2011-2018 Volt, which offered nearly identical performance regardless of whether it was running on battery alone or acting as a regular hybrid after the battery charge was depleted.
Mild Hybrids
Mild hybrids have electric motors that aren’t powerful enough to propel the vehicle alone. They may sit between the engine and transmission, or be part of an integrated starter-generator system in which a beefier electric motor replaces both those components. Fuel economy benefits here are far less dramatic, and they may not even be marketed under the name “hybrid.” Recent mild-hybrid systems often run at 48 volts. They deliver more power than the vehicle’s 12-volt system but are far less expensive than full hybrid systems that operate at 280 to 400 volts.
In conclusion, hybrid technology has come a long way since its introduction. Understanding the different types of hybrids available can help you make an informed decision when shopping for a new vehicle. Whether you’re looking for a fuel-efficient ride or an environmentally friendly option, there’s a hybrid out there for you.
