Discharge SOC display method

The invention provides a discharge SOC display method, which is applied to an SOC setting display system, and comprises the following steps: when a multimedia host detects that a user triggers a threshold setting instruction for a discharge SOC, the multimedia host displays a setting interface, the setting interface comprises a control object for setting the threshold of the discharge SOC, and the control object is used for setting the threshold of the discharge SOC; the user sets the threshold value of the discharge SOC based on the control object; the multimedia host detects whether the user completes setting of the threshold value of the discharge SOC, if yes, the multimedia host sends a setting request to the ECU system, and the setting request carries the threshold value of the discharge SOC; and the ECU system outputs a discharge instruction to the power battery based on the threshold value of the discharge SOC, and outputs a discharge termination instruction to the power battery when the SOC value of t
