Description

Technical Field

[0002] Most existing energy storage containers are fixed, meaning they can only be installed on fixed foundations. They have complex structures, are heavy, and can only provide power in specific areas, resulting in poor mobility. For some special application scenarios where the charging location is far from the usage location, traditional fixed energy storage containers cannot meet the needs. Furthermore, traditional energy storage containers can only be lifted, without considering other transportation methods.
