Kind Code:
A1
Abstract:
A hydrogen filling station control system and method, and a hydrogen filling station. The system comprises: a first compressor (101), a second compressor (102), a first storage tank (201), a measurement device, and a controller. The gas discharge pressure of the first compressor is less than the gas storage pressure of the first storage tank, and the gas discharge pressure of the second compressor is greater than or equal to the gas storage pressure of the first storage tank; the first compressor and the second compressor are connected to the first storage tank; the measurement device is used for measuring the pressure of the first storage tank; the controller is used for controlling the first compressor to inflate and pressurize the first storage tank, and when the pressure of the first storage tank is equal to a first preset pressure, controlling the second compressor to inflate and pressurize the first storage tank. The system can save the costs of compressors and reduce power consumption.
