Underground garage charging pile system

Abstract

The invention provides an underground garage charging pile system, comprising a main control device, a main circuit, sub-circuits and branch circuits connected to each charging pile, wherein the maincontrol device is connected to the main circuit, the main circuit is connected with each sub-circuit, each sub-circuit is connected with each branch circuit, electric control switches are installed oneach sub-circuit and each branch circuit, the main control device is connected with each electric control switch to control the on-off state of each circuit, a plurality of temperature sensors are uniformly distributed along each sub-circuit and each branch circuit, the main control device is connected with each temperature sensor for collecting the heating temperature of each circuit, when the temperature rise collected by the temperature sensor on a certain circuit exceeds a threshold, the main control device controls to turn off the electric control switches on the corresponding circuits step by step until the temperature drops to a set value, and then turns on the electric control switches on the corresponding circuits step by step again. The underground garage charging pile system has the advantages that the design is scientific, electronic components on the circuits can be prevented from being burnt down, and potential safety hazards of a power grid can be reduced.

Description

technical field [0001] The invention relates to an underground garage charging pile system. Background technique [0002] With the popularization and promotion of electric vehicles, more and more people begin to buy electric vehicles as family cars. The construction and upgrading of underground garages are equipped with more charging piles, but the capacity of an underground garage is usually large, which can accommodate hundreds of vehicles. For automobiles, if each vehicle is powered, it will inevitably cause the overload of the power grid and cause hidden dangers to the safety of the power grid. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The purpose of the present invention is to address the deficiencies of the prior art, thereby providing an underground garage charging pile system with scientific design, avoiding burning of electronic components on the circuit, and re...
