It is usually installed at the power access point of the charging pile to monitor and record the power consumption of electric vehicle charging for billing and management; the electric energy meter cabinet usually includes an electric energy measurement device, a data transmission module and a data storage device. Through the electric energy measurement device, the power consumption of the charging pile can be monitored in real time, including the start and end time of charging, the electric energy consumption of charging and other information; the existing electric energy meter cabinets for charging piles still have some problems when in use.

[0003] The existing charging pile power meter cabinet is large in size. When it needs to be moved, it usually requires multiple people to lift and move it, which is time-consuming and labor-intensive. In addition, when the internal environment of the cabinet is humid, it may cause circuit leakage, which poses a safety hazard to the power meter cabinet. Therefore, we have made improvements to this and proposed a power meter cabinet for a charging pile. Summary of the invention

When only the fan 401 is working, the inside of the cabinet 1 can also be cooled. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0054] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
