First, the smart charging pile scheme background


With the implementation and implementation of the new energy strategy and the implementation of the Guiding Opinions of the General Office of the State Council on Accelerating the Promotion and Application of New Energy Vehicles, the number of electric vehicles has continued to climb. The electric vehicle charging and replacing facilities that have been matched with it have taken the lead in construction, and have gradually formed an electric vehicle charging and replacing system that combines charging piles, charging stations, power stations, and other facilities.


Second, charging pile operation networking needs


With the rapid development of technology and the continuous influx of capital, new energy electric vehicle vehicles are developing rapidly. As the supporting infrastructure of electric vehicles, the charging pile is at the tuyere, and the prospect is huge. At present, the number of domestic charging piles is increasing day by day. With the rapid expansion of scale, it also brings a series of management needs, including:

1. The charging piles are scattered, and it is difficult for the owner to find the charging pile;

2, charging time is long, the owner waits for a long time;

3. The charging pile has a complicated structure and is difficult to maintain and manage;

4. The location of the charging piles is scattered, including the underground parking lot. The expressway may require a large number of charging piles, which is inconvenient to manage.

In order to help the charging pile enterprises to solve the above-mentioned actual needs, Shuncom proposed a smart charging pile to monitor the Internet of Things solution.

Third, Shuncom charging pile IoT monitoring solution overview


Shuncom charging pile monitoring IoT solution, with zigbee (LoRa), 4G and other wireless technologies, through wireless data transmission module, acquisition module, intelligent gateway and other Internet of Things devices, to achieve charging pile positioning, charging pile charging and discharging control, charging Pile status monitoring, environmental monitoring around the charging pile, unified management of multi-charge piles and other functions.

In view of the complicated structure of the charging pile, Shuncom uses a low-power zigbee (LoRa) wireless module embedded in the charging pile, and combines with the control system to collect the running data of current, voltage, power and power of the charging pile in real time. The downlink connection of the intelligent gateway is zigbee (LoRa) acquisition and transmission node, and the uplink connects the server and the terminal device through the WiFi/4G network. The collected real-time operation data of the charging pile is transparently transmitted to the terminal equipment platform through the intelligent gateway, and the unified management of the large-scale charging pile is realized through the platform.


Fourth, the composition of intelligent charging pile monitoring system

According to the regionality of the geographical location of the charging pile, it can be divided into two types: centralized type and discrete type. The data collected by each charging pile in each centralized area is transparently transmitted to the server and the cloud platform through the intelligent gateway.


Five, intelligent charging pile monitoring system IoT hardware solution


The intelligent charging pile monitoring system of electric vehicles mainly consists of four parts: sensing layer, transmission layer, application layer and terminal layer.

(1) sensing layer, including zigbee (LoRa) transmission node, data acquisition module, GPS module, current, voltage sensor, displacement sensor, infrared sensor, camera, etc.;

(2) Transport layer, including ZIGBEE+4G or LoRa+4G gateway devices, wireless connection devices, wireless transmission networks, etc.;

(3) The application layer is mainly a charging pile monitoring and management platform, which is responsible for monitoring and managing all connected charging piles;

(4) Terminal layer refers to smart phones, ipads, computers, PCs, etc.

Sixth, intelligent charging pile monitoring system function


1, charging pile status monitoring

The system uses the zigbee/LoRa module, data acquisition module, current, voltage sensor and other sensing devices to synchronously collect data such as current, voltage, switch status and protection status of the charging pile.


2, electric vehicle charging monitoring

Data collection such as input and output voltage, current, power, power factor, charging time, current charging mode, and charger failure status during charging.


3, image, video information collection

Each area is equipped with a camera to monitor the environmental information around the charging pile, to avoid the damage of the charging pile facilities, and to discover the equipment risks caused by the external harsh environment at the same time.


4, charging pile advertising screen multimedia advertising information release

According to the management platform, the content that the advertisement screen needs to be placed can be set.


5, asset positioning

Through the embedding of the GPS module, the position coordinates of each charging post can be clearly seen on the system platform map.


6. Centralized management of charging piles in decentralized layout

Through the terminal system management platform, centralized centralized management of remote large-scale charging piles can be realized, real-time control of terminal operating conditions, reduction of operating costs of charging pile enterprises, and improvement of service quality and economic benefits of operators.
