The present invention discloses a full-voltage large-current load experiment platform for a mobile direct-current melting ice device. The full-voltage large-current load experiment platform comprises a high-power water resistance load; with the experiment platform adopted, the effectiveness of the constructed high-power water resistance load can be verified; the high-power water resistance load is connected into a circuit through a wire; the state of the melting ice device can be read directly through using a sensor and a computer; and therefore, a full-voltage large-current load test can be performed on the melting ice device under the condition that the melting ice device is not connected into the circuit, and the correctness of the installation of the melting ice device and the communication performance of the melting ice device can be judged.
