The Various Engine Configurations Possible For a Hybrid Car

Auto Tech Outlook | Tuesday, November 02, 2021

A hybrid electric vehicle's battery cannot be recharged through a socket. Rather than that, the battery is charged using regenerative braking and the combustion engine.

FREMONT  CA:  A hybrid electric vehicle combines an internal combustion engine (gasoline or diesel thermal engine) with more electric motors that run on stored energy. These engines can operate in tandem or sequence. This combination enables people to maximize the benefits of each source of energy while minimizing the drawbacks. This conserves gasoline and lowers pollution without compromising performance. Hybrid motorization systems can save fuel by shutting off the thermal engine. At the same time, the vehicle is parked, idling at a stoplight, or when the electric motor's energy is sufficient to operate the vehicle without aid from the thermal engine. While the vehicle is idling, the battery also supplies energy to the air conditioner and accessories. If necessary, the thermal engine is reactivated to offer additional acceleration power.

Automobile makers employ a variety of hybrid designs to accomplish a variety of goals.

Parallel hybridization in a hybrid vehicle

This is the most prevalent hybrid kind. Parallel hybrid configurations connect the electric motor(s) and thermal engine(s) to a single transmission that integrates the two energy sources. Automatic, manual, or continuous variation transmissions are available (CVT). Due to their connection to the powertrain, these two energy sources are said to operate in parallel.

The transmission type and the output power of the thermal engine are the primary determinants of the parallel hybrid's behavior (starting, accelerating, etc.). In principle, parallel hybridization enables the operation of both types of engines in response to the vehicle's speed. Typically, up to 30 to 50 kilometers per hour, the electric motor drives the axle, and after then, the thermal engine assumes control.

Serial hybridization in a hybrid vehicle

The electric motor(s) are the only ones that provide driving force to the wheels in this system. Because the thermal engine is not connected to the wheels, its sole purpose is to charge the electric motor's battery.

For instance, the thermal engine can route the electrical current to the electric motor or charge the battery that stores the energy. The electric motor moves the vehicle by driving the wheels via a transmission shaft or a set of motor axles. This hybridization technique is relatively uncommon. The thermal engine functions similarly to a generator, generating the electricity required to propel the vehicle forward. However, this gives a more accurate representation of an electric car's driving experience, with gentler and more forceful acceleration.
