Description

CROSS-REFERENCE TO RELATED APPLICATION This is a 371 application of the International PCT application serial no. PCT/CN2021/081890, filed on Mar. 19, 2021, which claims the priority benefit of China Application No. 202010204976.6, filed on Mar. 20, 2020. The entirety of each of the above-mentioned patent applications is hereby incorporated by reference herein and made a part of this specification. BACKGROUND OF THE INVENTION Field of the Invention The invention relates to a green energy technique, in particular to a range extension system suitable for a transport. Description of Related Art An electric vehicle refers to a vehicle that uses a power supply to supply power to an electric motor, and the electric motor converts electrical energy into kinetic energy to propel the vehicle. At present, the electric vehicle has a certain popularity in the market. The electric energy adopted by the electric vehicle may come from ordinary batteries, lithium batteries, solid-state batteries, NiMH batteries, or a composite power supply system integrating fuel cells with ordinary batteries, lithium batteries, solid-state batteries, and NiMH batteries, and the range extension system includes the above and other devices and equipment that may increase the mileage of the vehicle, and of course also includes an range extension method for charging the battery. The fuel cell produces electrical energy via a chemical reaction between hydrogen and oxygen, which is then transmitted to the motor of the car and converted into kinetic energy to propel the vehicle. SUMMARY OF THE INVENTION In a transport (such as a pure electric car or a hybrid electric car or an electric scooter) that adopts an range extension system (such as a fuel cell power supply) known to the inventor, the supply of the fuel source may not be adjusted in real time according to the driving condition of the user, thereby causing unnecessary consumption of fuel and electric energy. The invention provides a range extension system including an range extension assembly, a fuel supply unit, and a second fuel storage device. The range extension assembly has a first fuel input portion and a second fuel input portion. The first fuel input portion is configured to receive a first fuel source. The second fuel input portion is configured to receive a second fuel source different from the first fuel source. The second fuel source and the first fuel source are mixed in the range extension assembly to generate an electrical output. The fuel supply unit is configured to provide the first fuel source to the first fuel input portion. The second fuel storage device is configured to store and provide the second fuel source to the second fuel input portion. In summary, the range extension systems of one or a plurality of embodiments of the invention may receive the first fuel source and the second fuel source via the first fuel input portion and the second fuel input portion, respectively. In turn, the first fuel source and the second fuel source are mixed in the range extension assembly to generate electrical output. In addition, in some embodiments, the first fuel storage device and the second fuel storage device may be used as supply sources of the first fuel source and the second fuel source, respectively. In some embodiments, the first fuel source control device and/or the second fuel source control device may suitably adjust the supply amount of the fuel source in real time according to different driving conditions of the user. In some embodiments, in the range extension system, fuel may also be provided directly and continuously from a gas storage cylinder to the range extension assembly via a first fuel source auxiliary control device and/or a second fuel source auxiliary control device when the user determines via a central control unit that power is insufficient and fuel needs to be provided. In some embodiments, when the load of the transport is higher, the gas storage cylinder may additionally add fuel to the range extension assembly via a first pressure balance valve and/or a second pressure balance valve of the range extension system, thereby increasing the power output of the range extension assembly. In some embodiments, the first fuel source may be provided by being configured with a blower; alternatively, the first fuel source may be selectively obtained from one of the blower and the first fuel storage device configured.
