In a specific implementation, the electric vehicle is parked on the rigid transport deck of the electric vehicle transport ship, the power battery is located at the bottom of the electric vehicle body, and the temperature sensing device is attached to the transport deck at the corresponding position of the power battery via the magnetic module 14. The temperature sensing device can monitor the temperature at the corresponding position through the temperature sensing module 13 and can transmit the detected temperature data wirelessly to the corresponding monitoring terminal. After the transport is completed, the temperature sensing device can be easily retrieved from the transport deck by hand.

[0041] In one possible implementation, the magnetic module 14 includes a magnet block 141 and a magnetic fixing piece 142;

[0042] The bottom of the box body 11 is provided with a fixing groove 111;
