HEV stands for Hybrid Electric Vehicle. It refers to a type of vehicle that combines an internal combustion engine (ICE) with an electric propulsion system, allowing the vehicle to operate on both conventional gasoline or diesel fuel and electric power.
The term "HEV" typically refers to vehicles that are designed to have a greater reliance on the electric powertrain compared to conventional internal combustion engines. These vehicles aim to reduce fuel consumption, lower emissions, and increase overall energy efficiency.
In an HEV, the electric propulsion system includes a battery pack that stores electric energy and an electric motor that assists the combustion engine. The electric motor assists the engine during acceleration, deceleration, and during other situations where additional power is required. Additionally, these vehicles often use regenerative braking, which converts kinetic energy into electricity to recharge the battery.
HEVs offer several advantages over conventional vehicles. They provide improved fuel efficiency, as the electric motor assists the engine and reduces the reliance on fossil fuels. This results in lower carbon dioxide emissions and reduced environmental impact. HEVs also contribute to quieter operation, especially during low-speed and idle conditions, as they rely on the electric motor rather than the engine.
Overall, HEVs are considered a stepping stone in the transition towards more sustainable transportation options. They combine the benefits of both internal combustion engines and electric vehicles, delivering improved fuel economy and reduced emissions without the limitations of range anxiety associated with fully electric vehicles.
