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 power supply system for an electric vehicle includes: a battery system including one battery pack or a plurality of battery packs connected in parallel which is/are controlled by a Battery Management System (BMS) to connected to and disconnect from a high-voltage DC bus of the electric vehicle, wherein the battery system powers the electric vehicle; a range extender (3) to generate a DC current so as to charge the battery system and/or power the electric vehicle; a controller (4) to control a power generating mode of the range extender (3), to control a connection status of each battery pack with the high-voltage DC bus of the electric vehicle, and/or to control a connection status of the range extender (3) with the high-voltage DC bus of the electric vehicle; and a plurality of switches arranged between each battery pack and the high-voltage DC bus of the electric vehicle, and/or between the range extender (3) and the high-voltage DC bus of the electric vehicle. A control method and an electric vehicle using the power supply system are also described. The parallel battery system is used together with the range extender to power the electric vehicle, featuring modularization, integration/easy maintenance, and high reliability.

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. The present disclosure enables a more reliable, precise, and flexible use of the mobile power supply, and even allows monitoring of the charging state via a mobile phone app; in addition, a user can rent, via a member network, the mobile power supply when needing to use an electric car to travel a long distance, and then return the mobile power supply after use.
