The ideal combination of an electric vehicle (EV) and a hybrid vehicle (HV) is how Toyota Motor Corporation describes the Prius plug-in hybrid vehicle (PHV). Toyota is positioning this PHV as the ultimate vehicle that's environmentally friendly and has many uses due to its capability to utilize a diverse range of energy sources.
Toyota said that this Prius plug-in hybrid concept is its first brand to use a lithium-ion battery as the drive battery. It is a PHV concept model that can be charged from an external power source such as household electricity.
Because it has a lithium-ion drive battery rather than a nickel-metal hydride battery, the car can be charged many times higher. In other words, the cruising range in electric vehicle mode is longer than that of a Prius with a nickel-metal hydride battery.
If you compare the fuel efficiency, the third-generation Prius is 38km/l while that of the PRIUS PLUG-IN HYBRID Concept is at least 55km/l (target).
By charging from an external power source such as a household electrical outlet, the cruising range in electric vehicle mode is extended, maximizing the benefits as an environmentally-considerate vehicle. Since the cruising distance as an electric vehicle increases, this means that the environmental benefits to the regular Prius are surpassed.
The car has lower CO2 emissions as well as reduced consumption of fossil fuels. Well, you´d have to consider charging times. Using household electricity, the car is fully charged after 180 minutes at 100V and 100 minutes at 200V.
This full charge allows the electric vehicle (EV) to have a cruising range target of at least 20km. You get the best of both worlds since the car can operate as an EV for short trips and as a hybrid vehicle (HV) for longer ones.
