The embodiment of the invention provides an energy management system and a charging station, and relates to the technical field of energy storage. The method comprises the steps that firstly, an Ethernet interface ammeter actively broadcasts ammeter information including own IP addresses and communication port numbers to a plurality of charging devices; secondly, the target charging equipment sends target equipment information including an IP address and a communication port number of the target charging equipment to the Ethernet interface ammeter according to the ammeter information; and finally, the Ethernet interface electric meter sends a communication request to the target charging equipment according to the target equipment information, so that communication connection is established between the Ethernet interface electric meter and the target charging equipment. Therefore, because the Ethernet interface electric meter sends the electric meter information in a broadcast mode, each charging device can receive the electric meter information and select whether to establish communication connection with the Ethernet interface electric meter or not according to own needs, so that communication faults caused by conflict between the Ethernet interface electric meter and the IP address of the charging device are avoided; and the efficiency and the accuracy of energy management are improved.
本申请实施例提供了一种能源管理系统及充电场站,涉及储能技术领域。首先以太网接口电表主动向多个充电设备广播包括自身IP地址和通信端口号的电表信息;其次目标充电设备根据电表信息,向以太网接口电表发送包括自身IP地址和通信端口号的目标设备信息;最后以太网接口电表根据目标设备信息向目标充电设备发送通信请求,以使以太网接口电表和目标充电设备建立通信连接。由此,因为以太网接口电表通过广播方式发送电表信息,所以每个充电设备都可以接收到电表信息并根据自身需要选择是否与以太网接口电表建立通信连接,从而避免了因以太网接口电表和充电设备的IP地址发生冲突而导致的通信故障,提高了能源管理的效率和准确性。
