Optionally, fig. 5 is a schematic diagram of a composition of another mobile charging vehicle according to an embodiment of the present utility model, where a thin solid line with an arrow in fig. 5 represents a communication connection, a thick solid line with an arrow represents a high-voltage electrical connection, and a thick dashed line with an arrow represents a low-voltage electrical connection. On the basis of the foregoing embodiment, referring to fig. 5, the mobile charging vehicle 100 further includes a power receiving seat 501, where the power receiving seat 501 is connected with the main dc converter 403, and is used for externally connecting with a power supplementing interface on the robotic arm 502 of the centralized power supplementing pile, so as to access to a power supplementing power supply. The main dc converter 403 is further configured to perform a third dc conversion on the power source accessed by the power receiving base 501, so as to generate a complementary power source that can directly charge the energy storage module 106. The connection between the power receiving pad 501 and the main dc converter 403 includes both a communication connection and an electrical connection.

Alternatively, with continued reference to fig. 5, based on the foregoing embodiments, the output voltage of the energy storage assembly 108 is charged by the desired charging voltage of the vehicle 404, illustratively, the output voltage of the energy storage assembly 108 is set between 750V and 1050V. The main dc converter 403 comprises a bi-directional non-isolated and output pure buck dc converter. By setting the output voltage of the energy storage assembly 108 to be higher than the voltage required by the charged vehicle 404, the dc conversion module can achieve external charging by only reducing the voltage in a pure manner under the condition of supplying power to the charging gun 104, thereby simplifying the IGBT structure and cost of the converter in the main dc converter 403 and reducing the weight, volume and cost of the entire main dc converter 403.

Optionally, with continued reference to fig. 5 based on the foregoing embodiment, the mobile charging car 100 further includes a serial screen 302, where the serial screen 302 is communicatively connected to the energy storage management system. The serial screen 302 may be used as a backup for the interactive screen 114 for debugging of later operation and maintenance personnel.

Optionally, with continued reference to fig. 5, the mobile charging vehicle 100 further includes a thermal management system 107, where the thermal management system 107 is electrically connected to the main dc converter 403, and the main dc converter 403 may perform a third dc conversion on the power provided by the energy storage module 106 to generate a liquid cooling power source, so as to supply power to the thermal management system 107. The thermal management system 107 is also communicatively coupled to a management component 109 that adjusts its state based on control signals from the management component 109. The thermal management system 107 is used for temperature adjustment of the whole vehicle device. The thermal management system 107 may include an air conditioner that may access the CAN communications of the entire vehicle and an air conditioner controller that is powered by the main dc converter 403. Illustratively, the thermal management system 107 may be a full vehicle integrated liquid cooling system, and may perform integrated liquid cooling for the energy storage module 106, the charging gun 104, the main dc converter 403, and the motor in the driving module 102.

Optionally, with continued reference to fig. 5 based on the foregoing embodiment, the mobile charging vehicle 100 further includes a low-voltage battery 503 and an auxiliary dc converter 504, where the auxiliary dc converter 504 is electrically connected to the main dc converter 403 and the low-voltage battery 503, respectively. In the power supplementing process, the auxiliary dc converter 504 may further dc convert the power supplementing power generated by the main dc converter 403 to generate a low-voltage dc power (i.e., a low-voltage power corresponding to the high-voltage power generated by the main dc converter 403) to supplement power to the low-voltage battery 503. In the normal operation process, if the low-voltage battery 503 has a low power, the auxiliary dc converter 504 may further perform dc conversion on the power source or other dc power sources output by the main dc converter 403, so as to generate a low-voltage dc power source to supplement power to the low-voltage battery 503. The low-voltage battery 503 is used to provide a stable low-voltage power supply for the low-voltage dc electrical appliance on the mobile charging vehicle 100, where the low-voltage dc electrical appliance may include a vehicle-end industrial personal computer 402, an interactive screen 114, a homing sensor 105, a controller in the driving module 102, a management system and a relay in the energy storage module 106, and an air-conditioning controller in the thermal management system 107.
