Description
technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to a distributed energy storage system using decommissioned batteries and a construction method thereof. Background technique [0002] With the continuous depletion of fossil fuels and the continuous deterioration of the environment, human beings are paying more and more attention to the utilization of renewable energy and the protection of the environment. In recent years, electric vehicles have gradually replaced traditional fuel vehicles, and the global electric vehicle market is growing rapidly. The sales and ownership of new energy electric vehicles are increasing, and the power batteries of electric vehicles need to be replaced when they decline to 80% of their initial capacity. The stock of electric vehicles continues to increase, and the power batteries that will be eliminated will also continue to increase. At present, new energy power batteries will en...
