DETAILED DESCRIPTION

[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] In the present disclosure, unless otherwise stated, the terms "first", "second", etc. are used to distinguish one element from another element and have no order or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limiting the present disclosure.

[0025] According to the specific implementation scheme provided by the present disclosure, Figures 1 to 3 As shown in the figure, a mobile charging vehicle is provided, including a vehicle body 5 and a gas turbine 1, a generator 2, a power battery 31 and an energy storage battery 32 arranged on the vehicle body 5, the gas turbine 1 is transmission-connected to the generator 2, the generator 2 is electrically connected to the power battery 31 through a first power supply circuit 41, and is electrically connected to the energy storage battery 32 through a second power supply circuit 42, and the power battery 31 and the energy storage battery 32 are respectively connected with a discharge port 51.

[0026] Through the above technical solution, in the mobile charging vehicle provided by the present disclosure, since the gas turbine 1 is adopted, the volume of the gas turbine 1 is smaller than that of the internal combustion engine, which is conducive to increasing the volume of the power battery 31 and / or the energy storage battery 32, and further conducive to increasing the endurance of the mobile charging vehicle. Here, the gas turbine 1 can charge the power battery 31 through the first power supply circuit 41, and charge the energy storage battery 32 through the second power supply circuit 42. Among them, when the mobile charging vehicle supplies power to an external vehicle, the discharge port 51 electrically connected to the power battery 31 and the discharge port 51 electrically connected to the energy storage battery 32 can charge an external vehicle respectively, thereby effectively improving the charging efficiency of the mobile charging vehicle. In addition, when only one external vehicle needs to be charged, one of the two discharge ports 51 can be flexibly selected. For example, when the power battery 31 has a high power level, the discharge port 51 electrically connected to the power battery 31 can be used to power the external vehicle. Similarly, when the power level of the energy storage battery 32 is high, the discharge port 51 electrically connected to the energy storage battery 32 can be used to power the external vehicle. Thus, the power guarantee performance of the mobile charging vehicle can be improved. Among them, the gas turbine 1 has the characteristics of small size and high output power, which can improve the charging efficiency of the power battery 31 and the energy storage battery 32 when the body space of the mobile charging vehicle is limited.

[0027] In the mobile charging vehicle provided in the present disclosure, as an exemplary embodiment, the energy storage battery 32 can be detachably connected to the vehicle body 5. In this way, when the vehicle that needs to be charged is located in an area where the mobile charging vehicle is difficult to drive, the energy storage battery 32 can be detached from the vehicle body 5 and transported to a designated area to increase the service radius of the mobile charging vehicle.

[0028] In the mobile charging vehicle provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 1 As shown in , a transformer 61 can be provided on the second power supply circuit 42, and the transformer 61 can also be connected between the energy storage battery 32 and the corresponding discharge port 51, and the second power supply circuit 42 is connected to the energy storage battery 32 and the generator 2, that is, the generator 2 and the energy storage battery 32 are both connected to the discharge port 51 through the transformer 61. In this way, when an external vehicle is connected to the discharge port 51 and needs to be charged, one of the energy storage battery 32 and the generator 2 can be selected to power the discharge port 51, and the voltage can be increased or decreased through the transformer 61 to meet the power transmission and application requirements when the external vehicle is charged. Therefore, the power guarantee performance of the mobile charging vehicle can be improved.

The intelligent fuel supply system controls the intelligent fuel supply system to provide the fuel flow required by the gas turbine 1 at different operating points according to the operating conditions of the gas turbine 1 provided by the controller. In the present disclosure, liquid ammonia is used as the fuel of the gas turbine 1. The liquid ammonia has stable chemical properties and is easy to transport. The product of the complete combustion of the liquid ammonia is pure and carbon-free, which can realize the green and clean energy supply of the gas turbine 1. In some other embodiments, the gas turbine 1 may also use other fuels, such as diesel, gasoline, aviation kerosene, etc., and the present disclosure does not make specific restrictions on this.

In addition, since the generator 2 is electrically connected to the power battery 31 through the first power supply circuit 41, the generator 2 may also supply power to the drive motor 72, or the generator 2 and the power battery 31 may supply power to the drive motor 72 at the same time, and the present disclosure does not impose any specific restrictions on this.

[0033] The gas turbine 1 has a fuel port 14 connected to the combustion chamber 12, and the diameter of the air inlet 13 can be larger than the diameter of the fuel port 14, so as to ensure that the mass ratio between air and fuel is in a suitable ratio as much as possible, thereby ensuring that the fuel is fully burned in the combustion chamber 12.

[0036] The mobile charging vehicle provided by the present disclosure has a plurality of driving modes to choose from when working. In the pure electric driving mode, only the power battery 31 provides electric energy for the drive motor 72. The electric energy of the power battery 31 is used to enable the drive motor 72 to drive the wheel 71 to rotate, thereby driving the mobile charging vehicle to travel; in the extended-range driving mode, the gas turbine 1 drives the generator 2 to generate electricity, thereby providing electric energy for the power battery 31.
