Abstract: A highly integrated mobile energy storage system is provided, which includes a container and battery racks. The battery racks are arranged in two rows along a length direction of the container, and the two rows of the battery racks are arranged back to back. For each of the two rows of battery racks, a maintenance door is arranged at a wall of the container close to the row of battery racks. In a case that a battery rack needs to be maintained, it is just required to open the maintenance door to maintain the battery rack. Since the two rows of battery racks are arranged back to back, no maintenance passage is required, thereby reducing a floor space along a width direction of the container, thus reducing the floor space of the system.
