[0061] In this embodiment of the invention, for other descriptions of steps 201-202, please refer to the detailed description of steps 101-104 and optional embodiments in Embodiment 1. This embodiment of the invention will not repeat the descriptions.

[0062] As can be seen, the power supply vehicle implementing this embodiment of the invention can calculate the total output power of all AC / DC power devices when it detects simultaneous access to external AC / DC power. When it is determined that the total output power is greater than the maximum output power of the AC / DC power supply allowed by the AC / DC circuit in the power supply vehicle, it dynamically adjusts the number of AC / DC power devices connected to the AC / DC power supply and intelligently allocates some AC power devices to the power circuit converted by the inverter unit / rectified by the rectifier unit. This reduces the load pressure of a single type of power supply, solves the technical problem of the single power supply used by electric construction machinery, broadens the application scenarios of electric construction machinery, and helps to improve the versatility and compatibility of the power supply vehicle, as well as the efficiency of electric construction machinery in earthwork operations.

[0063] It is evident that implementation is as follows Figure 2The described power control method for the power supply vehicle can determine the power parameters of the input power supply and the corresponding power parameters of the externally connected electrical equipment when an externally connected input power supply is detected. The power supply vehicle uses a control unit to determine whether the power parameters match the power supply parameters. When the power parameters match, the power supply vehicle outputs power matching the power parameters to the electrical equipment through a power distribution unit. When the power parameters do not match, the input power supply is adjusted to a target power supply that matches the power parameters, and the target power supply is output to the electrical equipment through the power distribution unit. When an external AC / DC power supply is detected simultaneously, the total output power of all AC electrical equipment is calculated. When the total output power exceeds the maximum AC power output allowed by the AC circuit in the power supply vehicle, the number of AC electrical equipment connected to the AC power supply is dynamically adjusted, and some AC electrical equipment is intelligently allocated to the AC power circuit converted by the inverter unit. This method can solve the technical problem of the single power supply used by electric construction machinery, broaden the application scenarios of electric construction machinery, improve the versatility and compatibility of the power supply vehicle, and improve the efficiency of electric construction machinery in earthmoving operations.

Figure 3 As shown, the power control device of the power supply vehicle may include a determining module 301, a judging module 302, an output module 303, and a first adjustment module 304. The determination module 301 is used to determine the power parameters of the input power source and the power consumption parameters of the externally connected electrical equipment when an input power source is detected from an external connection.

[0065] The judgment module 302 is used to determine whether the power consumption parameters determined by the determination module 301 match the power supply parameters through the control unit.

[0066] The output module 303 is used to output power matching the power parameters to the electrical equipment through the power distribution unit when the judgment module 302 determines that the power consumption parameters match the power supply parameters.

[0067] The first adjustment module 304 is used to adjust the input power supply to a target power supply that matches the power consumption parameters when the judgment module 302 determines that the power consumption parameters and the power supply parameters do not match.

[0068] The output module 303 is also used to output the target power adjusted by the first adjustment module 304 to the electrical equipment through the power distribution unit.

[0069] It is evident that implementation Figure 3 The described power supply vehicle's power control device can determine the power parameters of the input power source and the corresponding power parameters of the externally connected electrical equipment when it detects an input power source. The control unit determines whether the power parameters match the input power source. If the power parameters match, the power distribution unit outputs power matching the input power source to the electrical equipment. If the power parameters do not match, the input power source is adjusted to a target power source that matches the input power source, and the target power source is output to the electrical equipment through the power distribution unit. This solves the technical problem of the single power source used in electric construction machinery, broadens the application scenarios of electric construction machinery, and thus improves the versatility and compatibility of the power supply vehicle, as well as the efficiency of electric construction machinery in earthmoving operations.

[0087] The judgment module 302 is also used to determine whether the first total output power calculated by the calculation module 306 is greater than the maximum output power of the DC power supply preset by the power supply vehicle.

[0088] The determining module 301 is also used to determine the target DC power equipment that needs to be redistributed based on the preset maximum output power of the DC power supply of the power supply vehicle when the judging module 302 determines that the first total output power is greater than the preset maximum output power of the DC power supply of the power supply vehicle.
