Energy storage system

Abstract

The invention discloses an energy storage system, which comprises a series battery pack, a battery management module, a main control module and a touch screen module. The battery pack in series includes at least first and second battery packs, each battery pack includes at least one single cell battery, and the first and second battery packs are connected in series. The battery management module is connected to the series battery pack, and the battery management module is used to collect the power information of each battery pack in the series battery pack. The battery management module includes an active balancing module, and the active balancing module is used to control the first and second battery packs according to the power information. power balance among them. The main control module is connected with the battery management module for receiving power information. The touch screen module is connected with the main control module, and is used for receiving power information from the main control module and displaying a power information interface corresponding to the power information. Through the above method, the present invention can actively control the power balance among the battery packs in the series-connected battery pack, and can display the power of each battery pack in real time during the balancing process.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to an energy storage system. Background technique [0002] Solar photovoltaic power generation can reduce the use of non-renewable resources, and promote the application of solar photovoltaic power generation, which is of great significance to reduce the consumption of fossil energy and optimize the energy structure. The existing chassis-type home energy storage system is the most direct application of solar photovoltaic power generation. [0003] The energy storage system in the prior art can convert solar energy into electrical energy and store it in a battery pack, which brings great convenience to people's lives. However, the existing energy storage systems have at least the following deficiencies: [0004] 1. The energy storage system of the prior art generally adopts the passive balance of energy dissipation type when performing energy balance for each battery pack, which...

AI Technical Summary

Problems solved by technology

[0004] 1. When the energy storage system in the prior art balances the energy of each battery pack, it generally adopts an energy-dissipating passive balance, which brings about the problem of heat management, and the balance current is therefore limited to a small current range;

[0005] 2. The energy storage system of the prior art cannot visually display the power of each battery in real time
