Problems solved by technology

However, the energy storage system of the prior art has at least the following disadvantages: when the energy storage system of the prior art performs energy equalization on each battery pack, it generally adopts passive equalization of the energy dissipation type, which brings the problem of heat management Therefore, the balance current is limited to a small current range. When the load power of the energy storage system is large or the load power fluctuates instantaneously, the battery energy storage system cannot meet the power requirements of the load, resulting in the load not working normally.

The battery management module is connected to the battery packs connected in series and is used for collecting power amount information of each battery pack in the battery packsconnected in series. The battery management module comprises an active equalization module which is used for controlling the power balance between the first battery pack and the second battery pack according to the power amount information.

Description

technical field [0001] The invention belongs to the technical field of storage devices, and in particular relates to a high-efficiency electric energy storage device. Background technique [0002] 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 life. However, the energy storage system of the prior art has at least the following disadvantages: when the energy storage system of the prior art performs energy equalization on each battery pack, it generally adopts passive equalization of the energy dissipation type, which brings the problem of heat management Therefore, the balance current is limited to a small current range. When the load power of the energy storage system is large or the load power fluctuates instantaneously, the battery energy storage system cannot meet the power requirements of the load, resulting in the load not working properly.
