Energy storage system

Abstract

The invention discloses an energy storage system. The energy storage system comprises a series battery pack, a battery management module, a main control module and a touch screen module. The series battery pack at least comprises a first battery pack and a second battery pack, each battery pack at least comprises a single battery, and the first battery pack and the second battery pack are connected in series. The battery management module is connected with the series battery pack, the battery management module is used for acquiring electric quantity information of each battery pack in the series battery pack, the battery management module comprises an initiative balance module, and the initiative balance module is used for balancing the electric quantity between the first battery pack and the second battery pack. The main control module is connected with the battery management module and used for receiving the electric quantity information. The touch screen module is connected with the main control module and used for receiving the electric quantity information from the main control module and displaying an electric quantity information interface corresponding to the electric quantity information. By adopting the energy storage system, the electric quantity balance among the battery packs in the series battery pack can be initiatively controlled, and the electric quantity of each battery pack can be displayed in real time in the balance 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
