Abstract

An energy storage system is provided. The system includes an energy storage device including at least one battery module, a power adjuster that adjusts power of the energy storage device, a controller that controls the energy storage device and the power adjuster, a rack that accommodates the energy storage device, the power adjuster and the controller, the rack including at least one stationary coupler fixed to a movable unit and at least one support device that supports the energy storage system against the moveable unit.

First claim

What is claimed is:

1. An energy storage system comprising:
an energy storage device comprising at least one battery module;
a power adjuster configured to adjust power of the energy storage device;
a controller configured to control the energy storage device and the power adjuster;
a rack comprising at least one stationary coupler fixed to a vehicle and configured to accommodate the energy storage device, the power adjuster and the controller; and
at least one support device configured to support the energy storage system against the vehicle,
wherein the energy storage device provides energy for a specific function of the vehicle other than a driving function of the vehicle, and
wherein the controller establishes a communication connection with the vehicle and transmits a control signal to the vehicle via the communication connection for controlling the specific function of the vehicle.

2. The energy storage system of claim 1 , wherein the at least one support device comprises an anti-vibration device configured to couple to at least one damper for absorbing vibration of the vehicle.

3. The energy storage system of claim 1 , wherein the at least one support device comprises a caster configured to facilitate movement of the energy storage system with respect to the vehicle.

4. The energy storage system of claim 1 , wherein:
an upper portion of the rack is configured to accommodate the power adjuster;
a middle portion of the rack is configured to accommodate the controller; and
at a lower portion of the rack is configured to accommodate the energy storage device.

5. The energy storage system of claim 1 , wherein a portion of the rack in which the power adjuster is accommodated is thermally isolated from the energy storage device and controller.

6. The energy storage system of claim 5 , further comprising:
at least one ventilator configured to radiate heat from the isolated portion.

7. The energy storage system of claim 1 , the rack further comprises:
a ventilator for each of the at least one battery module.

8. The energy storage system of claim 1 , further comprising a user interface exposed externally from the rack and including at least:
a charge outlet configured to change one or more of the at least one battery module;
a discharge outlet configured to discharge power stored in one or more of the at least one battery module;
a vehicle interface configured to communicate with the vehicle;
an oil pressure interface configured to facilitate a specific function of the vehicle;
a circuit breaker configured to cut-off power of the energy storage system; or
a charge state display configured to display a charge state of the energy storage device.

9. The energy storage system of claim 1 , wherein the control signal limits movement of the vehicle and includes information indicating that one or more of the at least one battery module is being charged.

10. The energy storage system of claim 1 wherein the rack further comprises:
a first rack comprising a first stationary coupler fixed to the vehicle and configured to accommodate the energy storage device and the power adjuster; and
a second rack comprising a second stationary coupler fixed to the vehicle and configured to accommodate the controller.

11. The energy storage system of claim 10 , wherein:
an upper end of the first rack is configured to accommodate the power adjuster; and
a lower end of the first rack is configured to accommodate the energy storage device.

12. The energy storage system of claim 10 , further comprising:
at least one ventilator mounted to the first rack for each of the at least one battery module.

13. The energy storage system of claim 10 , further comprising:
a user interface exposed externally from the second rack and including at least:
a charge outlet configured to change one or more of the at least one battery module;
a discharge outlet configured to discharge power stored in one or more of the at least one battery module;
a vehicle interface configured to communicate with the vehicle;
an oil pressure interface configured to facilitate a specific function of the vehicle;
a circuit breaker configured to cut-off power of the energy storage system; or
a charge state display configured to display a charge state of the energy storage unit device.

14. The energy storage system of claim 13 , wherein the first rack and second rack are separate from each other and further comprising:
a power line configured to connect the first rack to the second rack.

15. The energy storage system of claim 1 , wherein the energy storage device further comprises a battery management system (BMS) configured to manage one or more of the at least one battery module.

16. The energy storage system of claim 15 , wherein the BMS is further configured to provide at least:
a protection control function of the one or more of the at least one battery module;
a lifecycle prediction control function of the one or more of the at least one battery module; or
a charge and discharge control function of the one or more of the at least one battery module.

17. The energy storage system of claim 1 , wherein the vehicle comprises a vehicle, a ship or heavy equipment.

18. The energy storage system of claim 1 , wherein the energy storage device further provides energy to the vehicle for driving the specific function such that carbon emissions and noise generated by the specific function are reduced.

19. An energy storage system comprising:
an energy storage device comprising at least one battery module;
a power adjuster configured to adjust power of the energy storage device;
a controller configured to control a vehicle to which the energy storage system is attached, the energy storage device and the power adjuster;
a rack comprising at least one stationary coupler fixed to the vehicle and configured to accommodate the energy storage device, the power adjuster, and the controller such that a portion of the rack in which the power adjuster is accommodated is thermally isolated from the energy storage device and controller;
at least one ventilator configured to radiate heat from the isolated portion of the rack;
a user interface exposed externally from the rack; and
at least one support device configured to support the energy storage system against the vehicle,
wherein the energy storage device provides energy for a specific function of the vehicle other than a driving function of the vehicle, and
wherein the controller establishes a communication connection with the vehicle and transmits a control signal to the vehicle via the communication connection for controlling the specific function of the vehicle.
