Detailed Description
The invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, two centralized control boards, namely a first centralized control board and a second centralized control board, are used, wherein the first centralized control board manages one group of chargers, and the second centralized control board manages the other group of chargers. The 6 chargers form a first group of chargers, and the other 6 chargers form a second group of chargers. Each charger is used for charging the battery of the electric vehicle.
The structure principle of the centralized control board card is shown in fig. 2, the centralized control board card comprises an SOC controller 4, a CAN interface 5 and a monitoring system communication interface 6, the CAN interface 5 is connected with the SOC controller 4, and the monitoring system communication interface 6 is connected with the SOC controller 4. The SOC controller 4 employs a SOC chip commonly found in the market for implementing communication and control logic with the charging device and business logic with the monitoring system. The CAN interface 5 is a physical interface for communication with the charger. The monitoring system communication interface 6 is a physical interface for communicating with the monitoring system, and the specific interface form can be selected according to the actual monitoring system communication mode, such as ethernet, wifi, bluetooth, and the like.
Each charger is from a communication controller, as shown in fig. 3, the communication controller of the charger comprises an SOC controller 7 and a CAN interface 8, and the CAN interface 8 is connected with the SOC controller 7. The SOC controller 7 adopts a common SOC chip in the market, which is a core of the communication controller and is used for realizing communication logic with the centralized control board card. The CAN interface 8 is a physical interface with the centralized control board card, and the CAN interface 8 is connected with the CAN interface 5 through a CAN bus.
As CAN be seen from fig. 1, each charger is connected as a node to the CAN bus 3. The networking method is specifically described as follows:
and equally dividing the chargers in the power exchange station into two groups, wherein each group is controlled by 1 centralized control board card. Each group of chargers is connected with the centralized control board card through a CAN bus. The CAN communication has higher real-time performance and reliability, uses a differential twisted pair to transmit data, has better anti-interference capability and has stronger adaptability to working environment.
The CAN bus communication protocol CAN be customized between the charger and the centralized control board card and is used for information interaction and command control between the charger and the centralized control board card. The charger reports the running state, charging information, equipment failure and other information to the centralized control board. The centralized control board card stores the related information of each charger and forwards or stores the corresponding information according to specific requirements. The centralized control board card uniformly receives the command issued from the monitoring system, and issues the control command to the corresponding charger through the CAN bus communication protocol. The centralized control board card can automatically plan the use scheme of the charger according to the state of each charger, so that the whole charging system is more intelligent. When faults occur, fault equipment can be positioned at the centralized control board card rapidly, so that the maintenance of the charging system is more convenient and quicker.
The charging machines #1 to #6 controlled by the first centralized control board card and the charging systems #7 to #12 controlled by the second centralized control board card are independent two sets of charging systems, a mutual backup relationship is formed between the charging systems, and when one charging system fails, the other charging system can work continuously without being affected completely.
