It is an important part of the development of distributed energy, smart grid, and energy Internet in the energy storage system. It can realize peak load shifting and valley filling of electricity consumption, save energy, and can be used in battery swap stations. For example, the battery pack of a new energy vehicle has a long waiting time when charging.
