Electromobile charging management device with billing function and application thereof

Abstract

The invention relates to an electromobile charging management device with a billing function and application thereof. The device comprises an embedded controller, a printer, a card reader, a display, a touch screen, a power supply module, audio equipment, a power supply control module and a metering module, wherein the power supply control module is connected with the embedded controller through a CAN (Controller Area Network) interface, and the metering module is connected with the power supply control module through a 485 bus so as to transmit electric quantity to the power supply control module. Compared with the prior art, the invention has the advantages of realizing user identity identification, judging the validity of a card, metering charged electric energy, and billing and charging according to charging time interval and peak / valley electrovalence, is capable of identifying the power supply type (alternating current or direct current) through the power supply control system information acquired from the internal CAN, has friendly operation interface, and provides a user with operation platforms for charging mode setting, charging information query, charging bill printing and others operations.

Description

technical field [0001] The invention relates to a charging control system of an electric vehicle charger, in particular to an electric vehicle charging management device with a billing function and its application. Background technique [0002] Facing the huge challenges of energy and environment, the technological change of automobile energy power system has become the focus and core of automobile technology development, which provides a historical opportunity for independent innovation and leapfrog development of my country's automobile industry. Electric vehicles are powered by electricity, can achieve "zero emission" and have low noise, which is an important means to solve energy and environmental problems. The charger provides energy supply for the operation of electric vehicles. It is an important basic support for electric vehicles and an important link in the commercialization and industrialization of electric vehicles. It has a significant impact on the development ...

Problems solved by technology

[0004]However, most of the chargers currently developed are in the stage of theoretical research and experiments, and are mainly aimed at specific demonstration projects and specific models, with different technical indicators. A unified standard is formed, and its charging management is basically integrated inside the charger, with unclear definitions, incomplete functions, poor portability, and lack of generalization and standardization conditions, which is not conducive to the development of electric vehicle industrialization
