[0002] At present, the multi-energy storage system refers to a comprehensive energy storage system that integrates multiple energy storage technologies and methods. This system converts various forms of energy such as electrical energy, thermal energy, kinetic energy, etc. into storable forms by utilizing different physical or chemical processes, and releases them for use when needed.

[0003] Existing technologies have shown certain limitations when dealing with energy issues. They can often only store and convert a single or a few energy forms. Not only is the efficiency relatively low, but the flexibility is also insufficient. When faced with a variety of energy forms, it is often difficult to achieve effective integration and utilization, which directly leads to energy waste and a decrease in overall efficiency. In addition, in terms of safety, existing technologies have also exposed obvious shortcomings and lack a comprehensive safety control mechanism to ensure the safety of energy transmission and conversion processes. In this process, existing technologies may not be able to detect potential abnormal situations in a timely manner, let alone deal with them quickly, which greatly increases the probability of accidents.
