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.

First claim

The invention claimed is:

1. An integrated mobile energy storage system, comprising:
a container, wherein the container is provided with a wire hole at a corner; and
battery racks, wherein
the battery racks are arranged in two rows along a length direction of the container, and the two rows of battery racks are arranged back to back within the container,
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,
the maintenance door is configured to be opened to maintain the battery racks,
the wire hole comprises a first wire hole arranged in a base of the container and extending through the base of the container,
the wire hole comprises a second wire hole and a third wire hole,
the second wire hole is arranged in a wall along a width direction of the container and extends through the wall along the width direction of the container, and
the third wire hole is arranged in the wall along the length direction of the container and extends through the wall along the length direction of the container.

2. The integrated mobile energy storage system according to claim 1 , further comprising L-shaped fixed adapters, wherein one side of each of the L-shaped fixed adapters is fixed to an outer surface of a wall of the container, and another side of the L-shaped fixed adapter is used to fix the container to an operation place.

3. The integrated mobile energy storage system according to claim 2 , wherein the L-shaped fixed adapters are arranged on outer surfaces of walls along the length direction of the container, and for each of the outer surfaces of the walls, three L-shaped fixed adapters are arranged.

4. The integrated mobile energy storage system according to claim 1 , wherein the container is further provided with a device compartment, and a power conversion system (PCS) is arranged in the device compartment.

5. The integrated mobile energy storage system according to claim 4 , wherein the device compartment and a battery control panel (BCP) are arranged adjacent to each other along a width direction of the container.

6. The integrated mobile energy storage system according to claim 1 , wherein a heating, ventilation and air conditioning (HVAC) system is arranged on a wall of the container.
