Abstract

The invention provides a heat dissipation control method and device and a charging pile and relates to the technical field of heat dissipation. The method comprises the steps of supplying power to heat dissipation equipment when to-be-charged equipment is connected with the charging pile; obtaining air inlet temperature and air outlet temperature of the charging pile and a real-time output power of the charging module; determining a working duty cycle of the heat dissipation equipment according to the air inlet temperature, the air outlet temperature, the real-time output power, the preset maximum temperature, preset allowable temperature rise and a preset rated power; and controlling the heat dissipation equipment to work according to the working duty cycle. The heat dissipation control method and device and the charging pile provided by the invention specifically have the technical effect of improving a utilization rate of system power.

Description

technical field [0001] The present invention relates to the technical field of heat dissipation, in particular, to a heat dissipation control method, device and charging pile. Background technique [0002] With the development of high-power charging technology, charging facilities will enter a new stage of rapid development. Due to the increase in charging power, the heat generated by the DC charger is also significantly increased. If the temperature rise is too high, the DC charger will reduce the output power, and the utilization rate of the system power will be low. How to balance the relationship between temperature rise and output power is a problem that must be solved for high-power charging. Contents of the invention [0003] The problem solved by the invention is that the utilization rate of system power in the prior art is low. [0004] In order to solve the above problems, in the first aspect, the present invention provides a heat dissipation control method, w...
