Description

Technical Field

[0001] The utility model relates to the technical field of charging station operation control, and in particular to a charging safety fence. Background Art

[0002] The structure of the existing DC charging pile includes a central processing module, a billing module, a card swiping module, an energy scheduling module, a human-machine interface module, a communication module, a charging interface and a guidance module. Its main function is to convert AC power into DC power to quickly replenish energy for electric vehicles.

[0003] There are two or more brands of DC charging piles at existing DC charging stations, and new ones are being added, resulting in two or more specifications of DC charging piles. All DC charging piles at the charging station are connected through cloud data, and the charging pile data is integrated into the charging station operation cloud platform for unified control. It is relatively cumbersome for the DC charging station operation platform to connect to different types of DC charging piles. At the same time, different display interfaces and control methods need to be developed for different DC charging piles. When abnormal situations occur during the charging process, there is no timely and effective way to control the charging piles. The specific technical problems that still need to be solved are as follows:

[0004] (1) There are differences in the communication protocols of DC charging piles from different manufacturers in existing charging stations. Different levels of development are required when connecting to the charging station operation platform. When different charging piles are added, the cloud platform needs to be redeveloped. The development reuse rate is low and the development cycle is long.

[0005] (2) The charging power of existing DC charging piles is mainly determined by the power demand of electric vehicles and the rated power of the charging piles. It is impossible to adjust the power of the charging station based on the actual operation of the DC charging station, which is dominated by the charging pile operation platform, and orderly charging cannot be achieved.

[0006] (3) During the charging process of existing DC charging piles, when abnormal conditions occur, electric vehicles and charging piles cannot limit power in a timely manner, thereby failing to ensure the safety and stability of the charging process. Utility Model Content

The charging safety fence uses the AC 220V power supply inside the charging pile. The charging safety fence is connected to the charging communication line inside the DC charging pile in an intrusive manner. It does not change the original DC charging pile line and does not affect the original function of the DC charging pile. It is reliable and safe.

[0030] Power module: HLK-PM03.

[0031] Rotary code module: MER-16H1.

[0032] The utility model discloses each functional module is connected according to the following mode and realizes relevant functions:

[0033] Referring to Figure 1 As shown in the drawing, the Lora communication module, power module, indicator light module and CAN communication module are connected with the main control module respectively, and the rotary code module is connected with the Lora communication module.

[0034] The CAN communication module is connected with the main control module through RS232 and SPI, can monitor the communication message of electric vehicle and charging pile in real time, realizes the charging power control of electric vehicle after receiving external control instruction, and guarantees the charging safety of electric vehicle.

[0035] The Lora communication module is connected to the main control module via RS232. The Lora communication module provides long-range wireless communication capabilities for the charging safety fence and supports uploading charging process messages to the Lora gateway in real time. At the same time, the Lora communication module also receives and parses commands from the cloud platform to remotely control and manage the electric vehicle charging process.

[0036] The main control module monitors the charging process of the electric vehicle in real time through the CAN communication module, monitors the relevant parameters in the charging process (such as current, voltage, power, etc.), processes the collected data, converts it into a standardized protocol and reports it to the Lora gateway, which then performs unified processing.

[0037] The indicator light module displays the real-time operating status and communication status of the current charging safety fence.

[0038] The power module provides the power required for the normal operation of the charging safety fence.

[0039] The rotary dial module supports manual adjustment of the communication address for the Lora communication module.

[0040] This utility model supports real-time monitoring of the communication status of electric vehicles and DC charging piles, and supports power regulation during the charging process to ensure smooth operation of the charging process; supports docking with DC charging piles of different brands and models, and realizes centralized management and regulation of charging piles; supports manual rotation of the dial to configure its own Lora communication address, reducing configuration steps and making debugging more intuitive.

[0041] After testing, the implementation of this utility model can achieve the following effects:

[0042] First, the charging safety fence can convert data from different DC charging piles into the standard data format of the operation platform, and report it to the Lora gateway of the charging station through wireless communication. The Lora gateway reports it to the operation platform. The operation platform performs unified data collection and control distribution for all charging piles in the DC charging station based on the standard data format, reducing the development workload.

[0043] Second, the charging safety fence can be installed intrusively inside the DC charging station, monitoring the communication messages between the electric vehicle and the DC charging station in real time. During normal charging, it will not affect the electric vehicle's charging process. When the overall charging station power needs to be adjusted, the operation platform sends control commands to each charging safety fence through the Lora gateway. The charging safety fence adjusts the vehicle's required charging power to the power limit required by the operation platform.

[0044] Third, the charging safety fence and Lora gateway use Lora wireless communication for networking, with a maximum communication distance of 3,000 meters. No additional communication cables are required. The charging safety fence comes standard with an address configuration dial.
