täishübriid

Täishübriid is an Estonian term that translates to "full hybrid" and refers to a vehicle that can be powered by both an internal combustion engine and an electric motor, with the ability to operate solely on electric power for a significant distance. This differs from mild hybrids, which typically rely on the electric motor to assist the gasoline engine rather than provide primary propulsion.

In a täishübriid system, the electric motor is usually more powerful and is connected to a larger battery pack than in a mild hybrid. This allows the vehicle to accelerate, cruise, and even travel at highway speeds using only electricity. The internal combustion engine can then be engaged when more power is needed, for longer journeys, or when the battery needs recharging. The transition between electric and gasoline power is typically seamless and managed automatically by the vehicle's control system.

The primary benefit of a täishübriid is its improved fuel efficiency and reduced emissions compared to conventional gasoline-powered vehicles. By utilizing electric power, especially in urban driving conditions with frequent stops and starts, the engine can be shut off, saving fuel and lowering pollutant output. The battery is recharged through regenerative braking, which captures energy normally lost as heat during deceleration, and by the internal combustion engine itself. Many täishübriid models also offer a plug-in option, allowing the battery to be charged from an external power source, further extending electric-only driving range.
