Examination method that realizes DC charging pile electrical energy error verification function

Abstract

The invention aims to provide an examination method that realizes a DC charging pile electrical energy error verification function, and aims to solve the DC charging pile detection technical field; anintelligent charging gun with a built-in check meter is connected with the DC charging pile and a power load, and the check meter can obtain an electric energy signal of the power load; an electric energy pulse detector obtains an electric energy pulse signal of the DC charging pile; a computer can exchange data with the check meter and the electric energy pulse detector via a wireless mode, compares the data collected by the check meter with the data obtained by the electric energy pulse detector, thus verifying the electric energy quantity error. The advantages are that the method can solvethe problems that a conventional DC charging pipe examination device is large in size and heavy in weight, and solves the problems that conventional detection equipment cannot measure in a long timeand hard to remotely monitor.

Description

technical field [0001] The invention relates to the technical field of DC charging pile detection technology, in particular to a testing method for realizing the electric energy error checking function of the DC charging pile. Background technique [0002] Because of its good environmental protection performance and energy-saving features, new energy vehicles can effectively reduce the harm to the environment, which has become the development trend of the automotive industry. The energy supplement of pure electric vehicles mainly depends on charging stations. DC fast charging is due to its fast and efficient characteristics. It is gradually replacing AC charging and becoming the mainstream charging method of charging stations. Corresponding to it is the rapid construction of DC charging stations, and the installation of DC chargers is constantly increasing. DC measurement will become the inevitable trend of its trade settlement. [0003] At present, for the detection device...

AI Technical Summary

Problems solved by technology

[0003] At present, for the detection devices of DC chargers in the market, the solutions proposed by major manufacturers all have some common features: large size, heavy weight, long-term monitoring difficulties, remote monitoring, high energy consumption, etc.

[0004] For users, the testing equipment generally used in traditional charger testing is a calibrator, which generally needs to be connected to a load box for testing. Does not really reflect the performance of the charger

In addition, the traditional detection method uses the load box as the load, which will cause a large amount of energy consumption, which does not meet the national concept of energy saving, emission reduction, and green environmental protection.
