Problems solved by technology

First of all, the charging pile has the characteristics of many control points, wide area and scattered, and lacks the communication ability with the charging pile operation management platform
Secondly, the definition of DC charging in the current national standard is not detailed enough. Different car companies have different understandings of this standard. For example, if a company develops an interface for a specific model in a city, then the model will serve when charging. It is relatively easy, but like in Beijing, there are many models, so each manufacturer's DC charging interface is different, and the charging card cannot be used universally.
Third, the operators are uneven and the management is not uniform; the settlement methods are inconsistent and cannot be settled uniformly, resulting in a large number of charging piles being idle, which seriously hinders the development of new energy vehicles

Embodiment 1

[0084] The present invention takes the two-dimensional code charging method as an example, and describes the sequence of charging implementation of the charging pile connected to the platform, see Figure 4 ,Specific steps are as follows:

[0085] 1. Establish a physical connection between the vehicle and the DC charging pile: the user connects the charging socket of the electric vehicle to the charging handle of the charging pile.

[0086] 2. The mobile APP scans the QR code on the pile body to obtain the pile code and mobile phone number. Enter the charging amount on the charging interface, and you can choose fixed charging or regular charging. / "Charging progress" to query the charging progress.

[0087] 3. Click the "Start Charging" button of the App, and the mobile phone connects to the communication server of the platform through the WebService service, and sends data such as pile codes and mobile phone numbers to the communication server and saves them in the Web serv...

Embodiment 2

[0100] If charging piles from other manufacturers are connected, only a few simple commands are required to connect to the conversion module. That is to say, the charging pile can be connected to the platform by replying to the transfer module query command start-stop command, request command and receiving the charging information, and realizes the charging function by scanning the code or swiping the card.

[0101] Here we take the query command and reply between the charging pile and the conversion module as an example to illustrate.

[0102] 1) Query command (sent by the conversion module to the charging pile)

[0103] serial number value length Format illustrate 0 header sequence 2 hex 0xf0, 0x0f 1 frame length 1 hex 2 0x00 1 hex command code 3 device ID 2 U16 4 CRC16 2 U16 frame check

[0104] 2) Query command reply (idle)

[0105]

[0106] i. The conversion module issues a query command: 0xf0 ...

Embodiment 3

[0114] The platform can modify the server IP address of the adapter module through the protocol, or remotely restart the charging pile through the protocol. These commands are commands issued by the platform only for the transfer module, and modify the parameters of the transfer module. Take modifying the server IP as an example to describe in detail.

[0115] 1) Modify the parameters of the transfer module (from the platform to the transfer module)

[0116] serial number value length Format illustrate 0 4 hex command serial number 1 0x0004 2 hex function code 2 downlink interface 1 hex 0: 232 interface; 1: 485 interface (default is 0) 3 uplink interface 1 hex 0: GPRS / 3G / 4G; 1: Zigbee; 2: WIFI; 3: TCP / IP; (default is 0) 3 communication mode 1 hex 0: single pile mode; 1: concentrator mode; (default is 0) 4 Server IP 4 hex For example, the server IP is 219.234.134.250 server port 2 hex ...

Abstract

The invention relates to a system and method for connecting DC charging piles to a charging facility operation management platform. According to the invention, each DC charging pile is externally connected to an external conversion module, the DC charging pile and the corresponding external conversion module are connected and communicated through an RS232 or 485 interface, the external conversion modules convert communication protocols of various charging facility manufacturers into a platform unified communication protocol, and transmit information such as the charging state of the charging piles to the charging facility operation management platform in a wireless mode, the external conversion module can also receive instructions sent by the charging facility operation management platform, modify parameter setting of the conversion modules and forward the instructions to the corresponding charging piles so as to realize unified dispatching, interconnection and interaction of charging piles of various manufacturers. The technical scheme provided by the invention can shield a circumstance that interfaces of various manufacturers are different, the DC charging piles are connected to the charging facility management platform by adopting the consistent communication protocol, monitoring and network interconnection are implemented on isolated charging piles and pile groups, information interaction is performed, unified management, unified billing and settlement are realized for the charging piles of various manufacturers, and an operator can dispatch and give instruction to the charging piles in a cross-manufacturer manner.

Description

technical field [0001] The invention relates to a system and a method for connecting a DC charging pile, in particular to a system and a method for connecting a DC charging pile to a charging facility operation management platform. Background technique [0002] The development of electric vehicles caters to the trend of low-carbon economy, which is conducive to optimizing the energy consumption structure and building an eco-friendly city. Because of this, the development of the electric vehicle industry has received strong support from the government and is also favored by major companies. As we all know, there is too little infrastructure for electric vehicle charging piles at present, which is one of the important factors restricting the development of electric vehicles. The electric vehicle charging pile is the most important facility in the electric vehicle charging system. It is generally fixed on the roadside or in the parking lot. Using a special charging interface, t...
