Abstract: A compressed air turbine DC power generator system, comprising: an aerodynamic turbine engine; a direct current generator (2) used for generating a direct current by using power output of the aerodynamic turbine engine as a driving input; and a control unit (3) used for controlling the rotating speed of the aerodynamic turbine engine to generate the power output and adjusting the output current and/or the output voltage of the direct current generator (2). The compressed air turbine DC power generator system is miniaturized and has high integration level, effectively overcomes the disadvantages such as low power density and great vibration noise of a power generation system with an internal combustion engine, and has a high industrial application value. The compressed air turbine DC power generator system can be used as an auxiliary power supply in the development process of an electric automobile, thereby effectively resolving the problem of range anxiety of a pure electric automobile.

Abstract: A portable and mobile power supply for an electric car. The power supply includes: a power generation unit (3); a system control and management module (15) configured to adjust an output power of the power generation unit, to output a direct current and a direct voltage capable of directly charging a power battery, to determine different charging control modes, to control the power generation output power of the power generation unit, and to control a charging voltage; a control panel (4) connected to the system control and management module; and a remote communication and GPS module (5) connected to the system control and management module, having a function of wireless remote communication and management and a function of supporting wireless positioning and switching by remote control, and being capable of remotely controlling the power generation unit to generate power and output the same to charge an in-vehicle power battery pack of an electric car.
