Electric energy billing device and new energy charging equipment

Abstract

The invention provides an electric energy billing device and new energy charging equipment, and the electric energy billing device comprises a voltage detection module, a current detection module, an electric energy statistics module, a control module, and a storage module. The voltage detection module is connected with the power input end of the new energy charging equipment and used for collecting input voltage information. The current detection module is connected with a power input end of the new energy charging equipment and is used for collecting input current information; the electric energy statistics module is connected with the voltage detection module and the current detection module and is used for calculating electric energy consumption information according to the input voltage information and the input current information; the control module is connected with the electric energy statistics module and the storage module and is used for calculating electric energy cost information according to the electric energy consumption information and the charging parameter information stored in the storage module and sending the electric energy consumption information and the electric energy cost information to the storage module for storage. Electric energy cost calculation can be realized in real time, power-off protection can also be realized, and information loss caused by power off can be prevented.

Description

technical field [0001] This article relates to the field of new energy electric vehicle charging, especially an electric energy billing device and new energy charging equipment. Background technique [0002] With the rapid development of the new energy electric vehicle industry, the charging capacity of charging equipment in new energy electric vehicles is also increasing. Therefore, higher requirements are placed on the accuracy, reliability and timeliness of charge billing. [0003] In the prior art, the charging equipment in the new energy electric vehicle does not integrate the billing function. If the charging equipment of the new energy electric vehicle wants to realize the billing function, it is generally used to calculate the charging amount with the help of a calculator or manually. Fee calculation. [0004] The above-mentioned billing method has the problem of large volume of industrial or civil meters, whether single-phase or three-phase, and the problem of limi...

AI Technical Summary

Problems solved by technology

[0006] This paper is used to solve the problem that the new energy charging equipment in the prior art uses the existing industrial or civilian electric meter to detect the charging amount, which makes it impossible to realize the billing function in real time

In addition, during the charging process, if the power supply is cut off, there is also the problem of easy loss of charging information.
