Energy management system and method for household energy storage product

Abstract

The invention relates to the household energy storage product management field, and particularly relates to an energy management system and a method for the household energy storage product. The system comprises a communication port configuration unit, a data acquisition unit, a data processing unit, a display unit and a power distribution unit. The method can provide a configuration function for the communication port, a configuration function for a port communication protocol, data acquisition, data processing, display and power distribution functions. The energy management system for the household energy storage product is introduced to the traditional household energy storage system, modules such as a battery and an inverter only need to meet communication with the energy management system for the household energy storage product, the coupling of the system is reduced, and the system stability is enhanced at a design level.

Description

technical field [0001] The invention relates to the field of management of household energy storage products, in particular to an energy management system and method for household energy storage products. Background technique [0002] With the reduction of the cost of batteries and electronic equipment, more and more household energy storage products are used as household appliances and appear in thousands of households. Conventional household energy storage products have two components. The first one is composed of batteries, inverters, and photovoltaic chargers. The battery or inverter is selected as the host of communication and system strategies to realize power control and Data acquisition and processing; the second type consists of an inverter and an energy storage inverter, where the energy storage inverter integrates the functions of the inverter and the photovoltaic charger in the first type. The present invention only analyzes the household energy storage products...

AI Technical Summary

Problems solved by technology

1) In commonly used household energy storage systems, all components are connected by direct communication. For example, battery components need to communicate with inverters and photovoltaic chargers, and the coupling between components is high. When one of the components has a change requirement, the associated components need to be changed to varying degrees, which increases the difficulty of change and project cost, and reduces the response speed to market demand; 2) In order to meet market demand, frequent components The change is also detrimental to the stability of the components; 3) The utilization rate of the photovoltaic charger is not high. Batteries often avoid this working condition by limiting the output of photovoltaic chargers, but this strategy directly leads to the reduction of photovoltaic output energy and affects user benefits

[0004] To sum up, while the existing scheme increases the difficulty and cost of project development, it is not conducive to quickly responding to market demand, and reduces the stability of batteries, inverters and other components and the photovoltaic revenue of users
