Embodiment Construction

[0020] In the following, the present invention will be further described in conjunction with the embodiments.

[0021] As shown in Figure 1, an intelligent energy storage system includes a main controller, an energy consumption monitoring device, a battery pack, a charger, a battery management system, an inverter, and a cloud server. The main controller is provided with an operation display The screen, cloud server, energy consumption monitoring device, and battery management system respectively exchange data with the main controller. The working status of the charger and battery pack is controlled by the battery management system. The inverter is used for the input and output voltage conversion and current conversion of the battery pack. , The energy consumption monitoring device is used to monitor the input power parameters of the mains and the output power parameters to the load; the intelligent energy storage system adds the main controller, energy consumption monitoring devic...

Abstract

The invention belongs to the technical field of energy storage, in particular to a control method of an intelligent energy storage system. The control method comprises the following steps that Step I, a battery management system obtains the current status information of a charger and a battery pack and uploads the information to a cloud server; Step II, an energy consumption monitoring device monitors electric power parameters of mains input and load output and uploads the electric power parameters to the cloud server; Step III, the cloud server stores the obtained various kinds of information, analyzes the information, finally feeds the analyzed result back to a main controller and displays the analyzed result on an operating display screen; and Step IV, working parameters are set, the main controller controls an inverter to work according to a set inverter mode and sends instructions to the battery management system according to set corresponding time, and the battery management system controls the charging and discharging of the battery pack. The control method of the intelligent energy storage system can cause users to reasonably utilize electric energy resource and plays roles of filling valley and modulating peak to a power grid.

Description

Technical field [0001] The invention belongs to the technical field of energy storage, and specifically relates to a control method of an energy storage system. Background technique [0002] With the continuous and rapid development of the national economy and the continuous improvement of people's living standards, the demand for electricity is increasing. Although the country's power generation continues to increase, it cannot meet the needs of people's lives and the development of industry and agriculture. At the same time, there is also a contradiction in the actual electricity consumption: during the day, it is at the peak of electricity consumption, and the power supply is severely insufficient, which restricts the development of industries, such as industry, agriculture, commerce, and transportation; from 11 pm to 7 am The section is the low point of electricity consumption, and the excess electric energy cannot be used well, causing serious waste of resources. Based on ...
