Electric vehicle charging facility remote monitoring system and method

Abstract

The invention provides an electric vehicle charging facility remote monitoring system and method. The system comprises a remote monitoring platform and a remote monitoring terminal. The remote monitoring terminal comprises a main control chip, an acquisition board, a power supply module, a 4G module, a CAN module, a temperature and humidity sensor, a smoke sensor, a voltage sampling unit, a current sampling unit and an SD memory card. The remote monitoring platform hardware comprises an information acquisition front-end processor, a database server and a WEB server; the remote monitoring platform software comprises a charging facility basic data monitoring module, an electric vehicle battery data analysis module, a message data monitoring module, a charging fault analysis module, a charging pile data analysis module and a charging pile use condition analysis module. According to the invention, data such as the output electrical quantity of the charging facility, the charging gun interface and the CAN message are fused, and the remote monitoring function of the operation state of the charging facility is realized by means of model establishment, big data analysis and the like.

Description

technical field [0001] The invention belongs to the technical field of charging facility monitoring, and in particular relates to a remote monitoring system and method for electric vehicle charging facilities. Background technique [0002] With the continuous growth of the electric vehicle application market, the scale of the supporting charging facilities is rapidly increasing. Charging facilities belong to system integration equipment, mainly including rectifier modules, main control units, contactors, charging guns, circuit breakers and other hardware and charging system software. Overall, the technology of the entire pile is still in the development stage, and the product maturity is not high. In addition, most of the charging stations are placed outdoors and operate online in an unattended manner, facing severe environments such as high temperature, high heat, and high salt. Even security incidents. [0003] At present, the operation and maintenance of charging facili...

Problems solved by technology

Charging facilities belong to system integration equipment, mainly including rectifier module, main control unit, contactor, charging gun, circuit breaker and other hardware and charging system software. Overall, the whole pile technology is still in the development stage, and the product maturity is not high.

In addition, most of the charging stations are placed outdoors and operate online in an unattended manner, facing harsh environments such as high temperature, high heat, and high salt. According to feedback from the current market situation, it is found that various charging faults and abnormalities occur in charging facilities during actual operation. even security incidents

[0003] At present, the operation and maintenance of charging facilities cannot realize real-time processing, and the corresponding response mechanism is not perfect, which leads to insufficient timely analysis and processing of charging faults and fault phenomena, and in the event of charging faults, car burning during charging and other accidents, there is a lack of technical means to restore complete charging Therefore, it is necessary to study a remote monitoring system and method that can transmit vehicle-pile interactive messages in real time and judge the operating status of charging piles.
