Abstract

The invention discloses a micro-gas turbine range extender suitable for an electric vehicle. The micro-gas turbine range extender suitable for the electric vehicle comprises a centrifugal-flow compressor, a heat regenerator, a combustion chamber, an oil supply system, an ignition device, a turbine engine, an integrated starting / power generation integrated motor, a driving motor and a power battery; the centrifugal-flow compressor is coaxially driven by the turbine engine; the turbine engine is driven by fuel generated by the combustion chamber; waste gas in an outlet of the turbine engine transmits waste heat per se to pressurized air generated by the centrifugal-flow compressor through the heat regenerator; the integrated starting / power generation integrated motor is coaxially driven by the turbine engine; the driving motor can be supplied with power by the integrated starting / power generation integrated motor and / or the power battery; the power battery can receive electric energy fedback by regenerative braking of the driving motor and can be charged by using the integrated starting / power generation integrated motor when the power capacity is low; and the power battery can be charged by using an external common alternating current power supply wire when the electric vehicle is in a stopping state. According to the micro-gas turbine range extender suitable for the electric vehicle, problems of short endurance mileage, low energy density and long charging time of a pure electric vehicle are solved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a micro-combustion engine range extender suitable for electric vehicles. Background technique [0002] In recent years, pure electric vehicles have developed rapidly in China as motor vehicle emission control regulations have become more stringent. However, the shortcomings of its short cruising range and incomplete related supporting facilities have also been highlighted. The fundamental reason is that pure electric vehicles can only be charged after parking or entering the station. Contents of the invention [0003] In view of the above problems, the present invention proposes a micro-gas turbine range extender suitable for electric vehicles. When the vehicle-mounted rechargeable power battery cannot meet the mileage requirements, the micro-gas turbine range extender can provide electric energy for the vehicle power system. Improve its endurance. [0004] The technical mean...
