The invention provides a temperature control method for a liquid cooling over-charging pile in the technical field of charging piles. The temperature control method comprises the following steps: step S10, creating a thermal resistance model; step S20, performing parameter setting on the thermal resistance model to obtain thermal resistance parameters; s30, the liquid cooling over-charging pile obtains the line internal resistance, the output current and the environment temperature; s40, the liquid cooling over-charging pile calculates the fan opening degree, the pump opening degree and the theoretical gun head temperature based on the thermal resistance parameter, the line internal resistance, the output current and the environment temperature; s50, the liquid cooling over-charging pile starts charging based on the fan opening degree, the pump opening degree and the output current; and S60, in the charging process, the actually-measured gun temperature of the charging gun is collected through a temperature sampling circuit, and the output current, the fan opening degree and the pump opening degree are dynamically adjusted based on the actually-measured gun temperature, the theoretical gun head temperature and the maximum steady-state temperature of the gun head. The method has the advantages that the flexibility and convenience of temperature control of the liquid cooling over-charging pile are greatly improved, and the power consumption is greatly reduced.
