The invention discloses a power output device for a hybrid electric vehicle. The power output device comprises an engine, a generator, a first super-capacitor, a second super-capacitor and an electric generator, wherein the electric generator is used for working under driving of electric energy which is outputted by the first super-capacitor or the second super-capacitor; the power output device further comprises a first switching component, a second switching component and a vehicle controller; depending on a current working mode of the hybrid electric vehicle, the vehicle controller is used for controlling the first switching component to charge either the first super-capacitor or the second super-capacitor, and controlling the second switching component to discharge either the second super-capacitor or the first super-capacitor towards the electric generator so as to drive the electric generator to work. Furthermore, the invention discloses the hybrid electric vehicle. According to the power output device, the problem that the capacitance of the super-capacitor is low, and the mileage of the hybrid electric vehicle is improved; and in addition, the super-capacitor is used as an energy storing device of the car, therefore, the safety performance is high, the service life is long and the pollution is avoided.
Description
technical field [0001] The invention relates to the technical field of automotive power components, in particular to a power output device for a hybrid vehicle and a hybrid vehicle with the power output device. Background technique [0002] Hybrid Power Automobile (Hybrid Power Automobile) refers to the vehicle equipped with more than two power sources: storage battery, fuel cell, solar cell, generator set of diesel locomotive. At present, under the background of the pollution of fuel vehicles to the environment and the rising international oil prices, hybrid vehicles, as a branch of green new energy technology, can realize transportation energy by using its zero emission, low noise and relatively simple structure. The advantages such as diversification of sources have attracted more and more attention, and the market share has also increased year by year. [0003] Traditional hybrid vehicles use batteries as energy storage media, and use electricity instead of fuel to driv...
