[0049] Example 4

[0050] Based on Examples 1, 2, and 3, in this embodiment, a fast-charge solenoid valve and a slow-charge solenoid valve are provided at the charging interface.

The first pressure relief speed is greater than the second pressure relief speed.

[0052] When a detection test is required, the control component controls the fast charging solenoid valve to quickly supply pressure to the pressure accumulator component at a first charging speed. When the pressure in the pressure accumulator component approaches a preset pressure value, the fast charging solenoid valve is closed, the slow charging solenoid valve is opened, and pressure is supplied to the pressure accumulator component at a second charging speed. When the pressure in the pressure accumulator component reaches a preset pressure value, the pressure accumulator component is maintained by the charging component. During the pressure maintaining process, if the pressure value in the pressure accumulator component is greater than the preset pressure value, the pressure is discharged to the outside at a second pressure discharge speed through the slow discharge solenoid valve, so that the pressure in the pressure accumulator component drops to the preset pressure value. When the detection test is completed, the pressure in the pressure accumulator component is quickly reduced at the first pressure discharge speed through the fast discharge solenoid valve.
