Embodiment Construction

[0062] The present invention will be further described below in conjunction with specific embodiments with reference to the accompanying drawings.

[0063] It should be noted that components in the various figures may be shown exaggerated for the purpose of illustration and are not necessarily true to scale. In the various figures, identical or functionally identical components are assigned the same reference symbols.

[0064] In the present invention, unless otherwise specified, "arranged on", "arranged on" and "arranged on" do not exclude the presence of intermediates between the two. In addition, "arranged on or above" only means the relative positional relationship between two parts, and under certain circumstances, such as after the product direction is reversed, it can also be converted to "arranged under or below", and vice versa Of course.

[0065] In the present invention, each embodiment is only intended to illustrate the solutions of the present invention, and sho...

Abstract

The present invention provides a battery management system for managing a battery system. The battery system comprises a plurality of battery clusters, each battery cluster comprising a plurality of battery packs, and the battery management system comprises a plurality of battery cluster management systems, wherein each battery cluster management system is configured to manage the corresponding battery cluster; one battery cluster management system of the plurality of battery cluster management systems acts as a main management system to manage other battery clusters, and one or more battery cluster management systems other than the main management system act as the alternative main management systems.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a battery management system. Background technique [0002] As a cornerstone of the smart grid development process, the microgrid can economically and environmentally friendly access to a large number of renewable energy sources (such as photovoltaics, wind turbines, fuel cells, etc.). Due to the inherent intermittent and random characteristics of new energy generation such as wind energy and solar energy, it will have adverse effects on the safe and stable operation of the power grid. The development of energy storage technology can improve its operation quality. A reasonable and efficient battery management system plays a vital role in the life of the battery pack and the safety of the entire battery system. [0003] Microgrids can be grid-connected or isolated to improve power supply reliability. Layered control strategies are widely used in microgrids, that is, the lowe...
