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 having a pair of sidewalls that extend in a length direction of the container and a pair of sidewalls that extend in a width direction of the container; and
a plurality of battery racks positioned in the container,
wherein the plurality of battery racks are arranged in two rows along the length direction of the container,
each battery rack of the plurality of battery racks has a front side that is configured to be serviced and a back side,
the two rows of battery racks are arranged in a way that the back side of each of plurality of battery racks in one row faces and is immediately adjacent to the back side of each of the plurality of battery racks in the other row and such that the front side of each of the plurality of battery racks in each row faces a respective sidewall that extends in the length direction, and
a maintenance door is arranged on at least one of the sidewalls that extends in the length direction of the container, the maintenance door being configured to be opened to access the front sides of the plurality of battery racks to maintain the plurality of battery racks.

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 provided with a wire hole at a corner.

5. The integrated mobile energy storage system according to claim 4 , wherein the wire hole comprises a first wire hole arranged in a base of the container and extending through the base of the container.

6. The integrated mobile energy storage system according to claim 5 , wherein the wire hole further comprises a second wire hole and a third wire hole, and 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.

7. 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.

8. The integrated mobile energy storage system according to claim 7 , wherein the device compartment and a battery control panel (BCP) are arranged adjacent to each other along a width direction of the container.

9. 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.
