What is hybrid?

*A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle. The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors.

Is this a new technology?

*simple answer is  no because mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, as power is delivered both via an internal combustion engine or electric motor and the rider's muscles. A common example that can be seen in Srilanka is MADURUWA / මදුරැවා electric bicycle.

*there are five main types of hybrid engines  

> Parallel hybrid - In a parallel hybrid the single electric motor and the internal combustion engine are installed so that they can both individually or together power the vehicle.

Example-  Honda Insight.

> Mild parallel hybrid - These types use a generally compact electric motor (usually <20 kW) to provide auto-stop/start features and to provide extra power assist during the acceleration, and to generate on the deceleration phase (aka regenerative braking).

Example - Honda Civic Hybrid, Honda CR-Z

> Power-split or series-parallel hybrid - in a power-split hybrid electric drive there are two motors: an electric motor and an internal combustion engine. The power from these two motors can be shared to drive the wheels via a power splitter, which is a simple planetary gear set. The ratio can be from 0-100% for the combustion engine, or 0-100% for the electric motor, or an anything in between, such as 40% for the electric motor and 60% for the combustion engine. The electric motor can act as a generator charging the batteries.

Example - Toyota Prius, Lexus RX400h, RX450h, GS450h, LS600h and CT200h.

> Series hybrid - Series-hybrid vehicles are driven by the electric motor with no mechanical connection to the engine. Instead there is an engine tuned for running a generator when the battery pack energy supply isn't sufficient for demands.

> Plug-in hybrid electrical vehicle - Another subtype added to the hybrid market is the Plug-in Hybrid Electric Vehicle (PHEV). The PHEV is usually a general fuel-electric (parallel or serial) hybrid with increased energy storage capacity (usually Li-ion batteries). It may be connected to mains electricity supply at the end of the journey to avoid charging using the on-board internal combustion engine.
