Hybrid vehicle architecture represents a critical transitional technology in the evolution of transportation from conventional internal combustion engine (ICE) vehicles to fully electric vehicles (EVs). These vehicles combine elements of both powertrain types, leveraging the benefits of electric propulsion while retaining the flexibility and range of traditional engines. In the context of zero-emission vehicles, hybrids serve as an essential bridge, facilitating the gradual shift in consumer behavior, infrastructure, and technology readiness. A hybrid vehicle typically incorporates both an internal combustion engine and one or more electric motors, along with a battery pack to store electrical energy. The architecture can vary from mild hybrids, where the electric motor assists the ICE, to full hybrids that can operate entirely on electric power for short distances, and plug-in hybrids that offer extended electric-only range with the ability to recharge from an external power source. This layered architecture allows manufacturers and users to balance fuel efficiency, emissions reduction, and driving performance without fully committing to an all-electric platform. One of the most important ways hybrid architecture bridges the gap is by addressing range anxiety, a common concern among prospective EV buyers. While fully electric vehicles rely solely on batteries, limiting driving range per charge, hybrids can switch seamlessly between electric and ICE propulsion. For example, in city driving where speeds are lower and regenerative braking can effectively recharge the battery, the vehicle can operate almost entirely on electric power, producing zero tailpipe emissions. During highway or long-distance travel, the ICE can provide additional power, extending range without requiring frequent stops for recharging. This dual-mode operation introduces drivers to the benefits of electric mobility while mitigating one of the primary limitations of fully electric vehicles. The energy management system in a hybrid vehicle is a key component of its bridging role. By intelligently controlling when to use the ICE, electric motor, or a combination of both, hybrid vehicles optimize fuel efficiency and minimize emissions under different driving
