Why Hybrid Electric Vehicles Need an Internal Combustion Engine

Hybrid electric vehicles (HEVs) combine an internal combustion engine (ICE) with an electric motor and battery system to enhance efficiency, performance, and range. This article delves into the necessity of an ICE in HEVs, discussing its role, benefits, and how it addresses the limitations of pure electric vehicles (EVs).

Extended Range

The primary function of an ICE in a hybrid vehicle is to extend its driving range. Unlike pure electric vehicles (EVs) that rely solely on battery power, HEVs can use the ICE to generate electricity, thus allowing the vehicle to travel further on a single charge. This is particularly useful for long-distance travel where charging stations are scarce.

Power Generation and Efficiency

The ICE in an HEV can also act as a generator, recharging the battery during driving. This function allows the vehicle to maintain battery levels without needing to be plugged in, offering users greater convenience. Moreover, the combination of an ICE and electric motor can optimize fuel consumption by using both power sources in tandem. The vehicle switches between power sources based on driving conditions, maximizing efficiency and minimizing emissions.

Performanceenhancing Benefits

One of the significant advantages of an ICE in an HEV is the improved performance it provides. The synergy between an electric motor and an ICE can deliver better acceleration and overall power. The electric motor can deliver instant torque, while the ICE can sustain higher speeds and provide power for extended durations.

Reduced Battery Size and Cost

The integration of an ICE in hybrid vehicles allows for the use of smaller batteries, reducing costs and weight. Smaller batteries can also lead to faster charging times, making the vehicle more practical for everyday use. This feature is particularly appealing for users who need a reliable, long-range vehicle without the need to completely switch to EVs.

Backup Power and Peace of Mind

Another crucial benefit of having an ICE in an HEV is the backup power it provides. In case the battery is depleted, the ICE ensures that the vehicle can still operate, offering peace of mind for drivers. This feature is especially important for long-distance travel and unexpected situations where electricity might not be available.

The Role of Internal Combustion Engines in Car Manufacturing

The necessity of ICEs in hybrid vehicles also reflects the industry's shift towards maintaining traditional engine and transmission manufacturing businesses. Car companies like General Motors (GM) faced a significant threat to their business models with the development of all-electric vehicles (EVs). However, the integration of ICEs into HEVs makes it easier for car buyers to gradually transition to electric technology while still familiarizing themselves with the benefits of hybrid technology.

The Shift Towards Battery Electric Vehicles (BEVs)

The next step in the evolution of hybrid vehicles is the plug-in hybrid electric vehicle (PHEV), which features a larger battery pack and a more powerful electric motor. PHEVs have become increasingly popular among individuals who wish to reduce their reliance on fossil fuels but are not yet ready to completely abandon ICEs. However, this phase of interest in PHEVs may be temporary as more people begin to appreciate the advantages of fully electric vehicles (EVs).

As the adoption of EVs grows and as drivers become more aware of the reduced maintenance, lower running costs, and increased reliability of electric vehicles, the rationale for hybrid vehicles using ICEs is likely to diminish. In the future, most new car purchases will likely be for fully electric vehicles, as users gravitate towards electric driving and the numerous benefits it offers.

Conclusion

The internal combustion engine in hybrid electric vehicles serves a crucial role in extending range, enhancing performance, and optimizing efficiency. As technology continues to advance and more drivers become familiar with the benefits of electric vehicles, the necessity for ICEs in HEVs may diminish. The transition to fully electric vehicles (EVs) represents a significant shift in how cars are designed and used, with electric propulsion becoming the norm in the future.
