[0024] Example 1

[0025] like Figure 1-2 As shown, this embodiment proposes a high-voltage power distribution device for a pure electric washing and sweeping vehicle, which is suitable for a high-voltage power distribution system including a battery module, a user module and a central controller.

[0026] In the present embodiment, the user module in the high-voltage power distribution system of the pure electric washing and sweeping vehicle includes a left fan, a right fan, a high-pressure water pump and an oil pump. In order to facilitate the positioning of faults of various electrical equipment in the high-voltage power distribution system and the power distribution structure, so as to perform more intelligent power distribution control, the present embodiment proposes that the high-voltage power distribution device 1 is specifically composed as follows.

[0027] The high-voltage power distribution device 1 includes a controller module, at least four monitoring terminals, and a wireless communication module:

[0028] The controller module includes a left fan motor controller and a fuse FU1 connected thereto, a right fan motor controller and a fuse FU2 connected thereto, a high-pressure water pump motor controller and a fuse FU3 connected thereto, and an oil pump motor controller and a fuse FU4 connected thereto; it can be understood that the above-mentioned controllers and their corresponding fuses are located on the same path.

[0029] At least four monitoring terminals are correspondingly arranged at both ends of fuse FU1, fuse FU2, fuse FU3, and fuse FU4, and are used to obtain voltage information and temperature information of fuse FU1, fuse FU2, fuse FU3, and fuse FU4.

[0030] Furthermore, the monitoring terminal includes a voltage sensor and a temperature sensor for detecting the voltage information and temperature information of the above-mentioned fuse in real time, and the voltage sensor and the temperature sensor can be actively powered sensors, such as those supported by an external DC power supply or an AC power supply of the high-voltage power distribution system to work normally. The specific power supply method is not limited in this embodiment.

[0031] In this embodiment, when the pure electric washing and sweeping vehicle is used outdoors, the fuse is easily affected by the ambient temperature. The present application monitors the voltage and temperature information of each fuse in the circuit where each electrical equipment is located through a monitoring terminal to determine whether the fuse is working normally, or is damaged or blown.

[0032] Correspondingly, fuse FU1, fuse FU2, fuse FU3, and fuse FU4 can be matched with models of corresponding sizes according to the power of different electrical equipment. In addition, voltage sensors and temperature sensors can be adaptively selected according to the fuse models, and this application does not further limit this.

At the same time, it can be beneficial to the subsequent maintenance of the vehicle's high-voltage equipment, minimize fault nodes, and reduce the operating cost of the entire vehicle.

The high-voltage power distribution device 1 includes a battery input 11 provided on the outer shell, and the battery module is connected to the battery input 11 and supplies power to the power module through the controller module.
