An energy storage management system and method based on carrier communication

Abstract

The invention discloses an energy storage management system and a method based on carrier communication, which relate to the technical field of carrier communication and energy storage battery management. The system comprises: a plurality of node acquisition communication control modules and a data convergence processing terminal; The node collecting communication control module is used for collecting the voltage information and temperature information of the energy storage node connected with the node, and converting the collected information into the node uplink carrier signal and sending itto the power supply cable. A data convergence processing terminal receives a node uplink carrier signal sent by a communication control module collected by a plurality of nodes through a power supplycable, The power equalization parameter is generated based on the uplink carrier signal, and the power equalization parameter is converted into the terminal downlink carrier signal, which is sent tothe node acquisition communication control module through the power supply cable to control its output voltage. The invention saves the acquisition cable, makes the design structure of the energy storage system simple and clear, improves the stability of the system and is convenient for later maintenance.

Description

technical field [0001] The invention relates to the technical field of carrier communication and energy storage battery management, in particular to an energy storage management system and method based on carrier communication. Background technique [0002] Currently, energy storage systems use batteries as energy storage units. [0003] Traditional energy storage system management solutions (including battery management systems (BMS)) are based on specific battery management chips, which need to consider the characteristics of the batteries in the energy storage system (including battery types, production consistency, etc.), battery The series-parallel combination mode and the acquisition and control mode of the system. The system collects parameters such as battery voltage, temperature, and charge and discharge current, and completes the system-level management plan through the BMS control center. The advantage of the traditional solution is that the design is simple, th...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that the existing technology has the following defects: because of the distribution of batteries in the energy storage system, the collection points of the voltage and temperature of the batteries are relatively scattered, and the design of the collection board is generally small, and it needs to be distributed inside the energy storage system. Many acquisition lines and control lines, the distribution of wiring harnesses make the system design complicated, and the maintenance cost of the system is high, which eventually leads to the shortening of the service life of the system and the increase of cost
