While electrically powered vehicles are certainly more environmentally friendly, sometimes it’s not feasible to depend entirely on electricity. Hybrid cars combine the power of gasoline with the economic and environmental advantages of electricity. We’ll guide you through the different models available so you can get the best of both worlds. Hybrid vehicles are one that employs two or more separate forms of power, such as submarines that surface with diesel and sink with batteries. Pressurized fluid in mechanical hybrids is another way to store energy. The underlying concept behind hybrid cars is that various motors perform better at different speeds; the electric motor is better at providing torque, or turning power, while the combustion engine is better at keeping high speed (better than a typical electric motor). Switching from one to the other at the right time while speeding up results in a win-win in terms of energy savings, which translates to, for example, better fuel economy. An internal combustion engine and an electric motor that uses energy stored in batteries power hybrid electric cars. A hybrid electric vehicle’s battery cannot be charged by plugging it in. Instead, the battery is charged by the internal combustion engine and regenerative braking. Because of the additional power offered by the electric motor, a smaller engine may be possible. When the engine is halted, the battery may also power supplementary loads and decrease engine idle. These elements work together to improve fuel efficiency without losing performance.
