Fullhybrid

Fullhybrid, commonly written as full-hybrid or strong hybrid, refers to a category of hybrid electric vehicles (HEVs) whose propulsion can be provided by the internal combustion engine (ICE), an electric motor, or both. Unlike mild hybrids, full hybrids can drive the wheels using electricity alone for at least short distances and low speeds. Unlike plug-in hybrids, full hybrids do not rely on external charging; their battery is replenished primarily through the ICE and regenerative braking.

The propulsion system typically includes a battery pack, one or more electric machines, and a power-split device (often a planetary gearset) to manage power flow between engine, motor, and wheels. An electric motor can function as both motor and generator, allowing the ICE to be turned off when not needed and enabling electric-only operation under light or city driving conditions. The control system decides when to use electric power, the gasoline engine, or both, with the aim of improving fuel economy and reducing emissions.

Full hybrids are widely used in mainstream models from manufacturers such as Toyota, Lexus, and Honda. They are valued for fuel efficiency, especially in stop-and-go traffic, and for not requiring external charging. Limitations include higher purchase cost, added weight from the battery system, and limited electric-only range compared with plug-in hybrids. Overall, fullhybrids represent a approach to lowering consumption by integrating electric propulsion with traditional internal combustion propulsion.
