The communication interface 10 is communicatively connected to the vehicle control unit. That is, the power supply control system can interact with the vehicle control unit through the communication interface 10. Optionally, the power supply control system can be communicatively connected to the communication interface 10 via a CAN or LIN bus. The communication interface 10 is communicatively connected to the peripheral electrical device. When the peripheral electrical device is connected to the power supply control system, the parameter information of the peripheral electrical device can be transmitted to the vehicle control unit through the communication interface 10, and then the vehicle control unit transmits the vehicle information and the parameter information of the peripheral electrical device to the communication interface 10, thereby obtaining the vehicle information and the parameter information of the peripheral electrical device through the communication interface 10. The communication interface 10 is electrically connected to the processing unit 20, the processing unit 20 is electrically connected to the power conversion unit 30, the power conversion unit 30 is electrically connected to the power supply path of the inverter, and the power conversion unit 30 is electrically connected to the peripheral electrical device. The power supply path of the inverter refers to the power supply path after the power provided by the DC power supply is converted by the inverter. The processing unit 20 can determine whether the vehicle has an inverter based on the whole vehicle information. And the processing unit 20 can confirm the power supply information required by the peripheral electrical equipment based on the parameter information. When the processing unit 20 determines that the vehicle has an inverter based on the whole vehicle information and confirms that the peripheral electrical equipment requires AC power based on the parameter information, it controls the power conversion unit 30 to connect the power supply path of the inverter with the peripheral electrical equipment, thereby directly supplying power to the peripheral electrical equipment through the power supply path of the inverter, thereby realizing power supply to the peripheral electrical equipment that requires AC power, and improving compatibility. At the same time, when the vehicle has an inverter, AC power can be directly provided to the peripheral electrical equipment through the power supply path of the inverter, without the need to set an AC-DC conversion module in the power conversion unit, which is conducive to reducing production costs, and compared with a separately set AC-DC conversion module, the conversion efficiency of the converter in the vehicle is higher, and directly providing AC power to the peripheral electrical equipment through the power supply path of the inverter can provide higher conversion efficiency.

When the switching unit 31 is turned on, the power supply path of the inverter can directly supply power to the peripheral electrical device, thereby providing power to the peripheral electrical device that requires AC power. When the switching unit 31 is turned off, the power supply path of the inverter is in a cut-off state and cannot supply power to the peripheral electrical device.

[0037] When the processing unit 20 determines that the vehicle has an inverter based on the vehicle information and confirms that the peripheral electrical equipment requires AC power based on the parameter information, it controls the switching switch unit 31 of the power conversion unit 30 to be turned on, so that the power supply path of the inverter can directly supply power to the peripheral electrical equipment, thereby realizing power supply to the peripheral electrical equipment that requires AC power.

[0049] Continue to refer Figure 3 , in some optional embodiments, the power conversion unit 30 further includes a DC-DC conversion module 33;

[0050] The processing unit 20 is further configured to control the DC-DC conversion module 33 of the power conversion unit 30 to convert the power signal of the DC power supply and provide it to the peripheral electrical device when it is determined based on the parameter information that the peripheral electrical device requires a DC power supply.

[0056] Figure 4 This is a module diagram of another power supply control system provided by the present disclosure, refer to Figure 4 In some optional embodiments, the power supply control system further includes a monitoring module 40, which is electrically connected to the power conversion unit 30 and the communication interface 10, respectively. The monitoring module 40 is used to monitor the output status of the power conversion unit 30 in real time and report the monitoring data to the vehicle control unit through the communication interface 10;

[0057] The processing unit 20 is further configured to control the adjustment of the working state of the power conversion unit 30 according to the adjustment signal fed back by the vehicle control unit, so as to interrupt or maintain the power supply to the peripheral electrical equipment.

[0058] Specifically, the power supply control system also includes a monitoring module 40, which is electrically connected to the power conversion unit 30 and can monitor the output status of the power conversion unit 30 in real time. The monitoring module 40 is electrically connected to the communication interface 10, and the monitoring module 40 reports the monitoring data to the vehicle control unit through the communication interface 10.

[0059] The vehicle control unit generates an adjustment signal based on the received monitoring data, and feeds it back to the processing unit 20 through the communication interface 10. The processing unit 20 controls the adjustment of the working state of the power conversion unit 30 based on the adjustment signal fed back by the vehicle control unit to achieve the interruption or maintenance of the power supply to the peripheral electrical equipment. That is, when the monitoring module 40 monitors that the output state of the power conversion unit 30 is abnormal, the processing unit 20 controls the adjustment of the working state of the power conversion unit 30 to achieve the interruption of the power supply to the peripheral electrical equipment. Thereby, a closed-loop protection mechanism is realized to ensure the stability and safety of the power supply to the peripheral electrical equipment. For example, when the power supply path of the inverter is used to supply power to the peripheral electrical equipment, when the monitoring module 40 monitors that the output state of the power conversion unit 30 is abnormal, the processing unit 20 controls the switching unit 31 of the power conversion unit 30 to be closed, and the power supply to the peripheral electrical equipment is stopped.

[0060] Continue to refer Figure 4 In some optional embodiments, the processing unit 20 is also used to control the switching of the working states of the DC-AC conversion module 32 and the switching switch unit 31 in the power conversion unit 30 according to the adjustment signal fed back by the vehicle control unit when determining that the vehicle has an inverter based on the vehicle information and confirming that the peripheral electrical equipment requires AC power based on the parameter information.

[0061] Specifically, the power supply control system also includes a monitoring module 40, which is electrically connected to the power conversion unit 30 and can monitor the output status of the power conversion unit 30 in real time. The monitoring module 40 is electrically connected to the communication interface 10, and the monitoring module 40 reports the monitoring data to the vehicle control unit through the communication interface 10.

[0062] The vehicle control unit generates an adjustment signal based on the received monitoring data and feeds it back to the processing unit 20 via the communication interface 10. The processing unit 20 is further configured to control the switching of the operating states of the DC-AC conversion module 32 and the switching unit 31 in the power conversion unit 30 based on the adjustment signal fed back by the vehicle control unit, when it is determined based on the vehicle information that the vehicle has an inverter and when it is confirmed based on the parameter information that the peripheral electrical device requires AC power. That is, when the peripheral electrical device is powered through the power supply path of the inverter, if the monitoring module 40 monitors that the output state of the power conversion unit 30 is abnormal, the processing unit 20 controls the switching unit 31 of the power conversion unit 30 to close and controls the DC-AC conversion module 32 of the power conversion unit 30 to convert the power signal of the DC power supply and provide it to the peripheral electrical device, so as to ensure that the peripheral electrical device can be powered and avoid the failure of the peripheral electrical device to be powered due to an abnormality when the peripheral electrical device is powered through the power supply path of the inverter.

[0063] Continue to refer Figure 4 In some optional embodiments, the monitoring module 40 is electrically connected to the processing unit 20, and the monitoring module 40 is further configured to transmit local data and monitoring data to the processing unit 20;

[0064] The processing unit 20 is further configured to control the working state of the power conversion unit 30 according to local data and monitoring data when determining that communication is interrupted based on vehicle information, so as to interrupt or maintain power supply to peripheral electrical equipment.

[0065] Specifically, the power supply control system further includes a monitoring module 40, which is electrically connected to the power conversion unit 30 and can monitor the output status of the power conversion unit 30 in real time. The monitoring module 40 is electrically connected to the processing unit 20 and is also configured to transmit monitoring data to the processing unit 20. Simultaneously, the monitoring module 40 is also configured to transmit local data to the processing unit 20.

[0066] The processing unit 20 is also used to determine that the communication is interrupted according to the vehicle information, and to control the working state of the power conversion unit 30 according to the local data and monitoring data, so as to interrupt or maintain the power supply to the peripheral electrical equipment. That is, when the interaction between the power supply control system and the vehicle control unit fails and causes the communication to be interrupted, when the monitoring module 40 monitors that the output state of the power conversion unit 30 is abnormal, the processing unit 20 can directly control the adjustment of the working state of the power conversion unit 30 to interrupt the power supply to the peripheral electrical equipment. Thereby, a local closed-loop protection mechanism that does not rely on the vehicle control is realized, ensuring the stability and safety of the power supply to the peripheral electrical equipment. For example, when the power supply path of the inverter is used to supply power to the peripheral electrical equipment, when the monitoring module 40 monitors that the output state of the power conversion unit 30 is abnormal, the processing unit 20 directly controls the switching unit 31 of the power conversion unit 30 to be closed, and stops supplying power to the peripheral electrical equipment.

The power supply control system provided in the embodiment of the present disclosure includes a communication interface 10, a processing unit 20 and a power conversion unit 30. Among them, the communication interface 10 is communicatively connected to the vehicle control unit. That is, the power supply control system can interact with the vehicle control unit through the communication interface 10. Optionally, the power supply control system can be communicatively connected to the communication interface 10 via a CAN or LIN bus. The communication interface 10 is communicatively connected to the peripheral electrical equipment. When the peripheral electrical equipment is connected to the power supply control system, the parameter information of the peripheral electrical equipment can be transmitted to the vehicle control unit through the communication interface 10, and then the vehicle control unit transmits the vehicle information and the parameter information of the peripheral electrical equipment to the communication interface 10, thereby obtaining the vehicle information and the parameter information of the peripheral electrical equipment through the communication interface 10.

The inverter's power supply path refers to the power supply path after the inverter converts the power provided by the DC power supply. The processing unit 20 can determine whether the vehicle has an inverter based on the vehicle information. The processing unit 20 can also confirm the power supply information required by the peripheral electrical device based on the parameter information. When the processing unit 20 determines that the vehicle has an inverter based on the vehicle information and that the peripheral electrical device requires AC power based on the parameter information, it controls the power conversion unit 30 to connect the inverter's power supply path to the peripheral electrical device, thereby directly supplying power to the peripheral electrical device through the inverter's power supply path. This can achieve power supply to the peripheral electrical device requiring AC power, thereby improving compatibility. At the same time, if the vehicle has an inverter, AC power can be directly provided to the peripheral electrical device through the inverter's power supply path, eliminating the need to set an AC-DC conversion module in the power conversion unit, which helps reduce production costs. Compared with a separately set AC-DC conversion module, the conversion efficiency of the converter in the vehicle is higher. Providing AC power to the peripheral electrical device directly through the inverter's power supply path can provide higher conversion efficiency.
