Here Why Extended Range Electric Vehicles Make So Much Sense

One such alternative is the use of hydrogen fuel cells.

The Rise of Hydrogen Fuel Cells

Hydrogen fuel cells have been gaining traction in the automotive industry as a potential solution to the charging infrastructure problem. These cells convert chemical energy from hydrogen into electrical energy, producing only water and heat as byproducts. This makes them an attractive option for electric vehicles, as they can be refueled quickly and easily, without the need for a charging station.

Benefits of Hydrogen Fuel Cells

  • Zero Emissions: Hydrogen fuel cells produce no tailpipe emissions, making them an attractive option for environmentally conscious consumers.

    Instead, they provide power to the electric motor, which in turn powers the wheels. In other words, the EREV is a type of electric vehicle that uses an internal combustion engine to generate electricity, which is then used to propel the vehicle.

    The Basics of Onboard Auxiliary Power Units (APUs)

    What is an APU? An APU is a small, self-contained engine that generates electricity. In the context of EREVs, the APU is used to produce electricity that is then used to power the electric motor. The APU is typically a small, compact engine that is designed to be efficient and reliable. It is usually powered by a fuel source, such as gasoline or diesel. The APU is connected to the electric motor via a power transmission system. ### How Does an APU Work? The APU works by using a fuel source to generate electricity. The process involves the following steps:

  • The APU’s fuel source is ignited, producing a small amount of energy. The energy is then converted into electricity through a process called internal combustion. The electricity is then transmitted to the electric motor via the power transmission system.

    EREVs can charge their batteries from any power source, including solar panels, wind turbines, and even the sun’s rays.
