Abstract

Systems and methods for commissioning an energy storage system are disclosed. An example method for commissioning an ESS may include connecting a first energy storage system to an battery module, energizing, by the first energy storage system, the battery module, articulating one or more battery contactors within the first energy storage system to selectively couple the battery module to a power source, processing a battery contactor status of the one or more battery contactors to detect battery contactor errors, disengaging, responsive to not detecting any battery contactor errors, the battery module at the first energy storage system, and determining a status of the energy storage system.

First claim

What is claimed is:

1 . A method of commissioning an energy storage system, comprising:
connecting a first energy storage system to an battery module; energizing, by the first energy storage system, the battery module; articulating one or more battery contactors within the first energy storage system to selectively couple the battery module to a power source; processing a battery contactor status of the one or more battery contactors to detect battery contactor errors; disengaging, responsive to not detecting any battery contactor errors, the battery module at the first energy storage system; and determining a status of the energy storage system.

2 . The method of claim 1 further comprising processing an energy storage system status to detect one or more system errors.

3 . The method of claim 2 , further comprising correcting, autonomously in response to detecting the one or more system errors, the one or more system errors.

4 . The method of claim 3 , wherein correcting the one or more system errors includes commanding, autonomously in response to detecting the one or more system errors, a circuit breaker in the first energy storage system to reset.

5 . The method of claim 2 , wherein articulating the one or more battery contactors within the first energy storage system is performed responsive to not detecting one or more system errors.

6 . The method of claim 1 , wherein processing the battery contactor status of the one or more battery contactors to detect one or more battery contactor errors includes detecting at least one stuck battery contactor.

7 . The method of claim 6 , further comprising commanding, autonomously in response to detecting the at least one stuck battery contactor, the at least one stuck battery contactor to reset.

8 . The method of claim 6 , further comprising prompting, in response to detecting the at least one stuck battery contactor, a user to manually correct the at least one stuck battery contactor.

9 . The method of claim 1 , wherein energizing the battery module includes engaging a mechanism to couple the battery module to the first energy storage system.

10 . The method of claim 9 , wherein engaging the mechanism includes engaging one of a switch, a relay, a contact, and a keyway.

11 . The method of claim 1 further comprising:
transmitting energy from the first energy storage system to a subordinate energy storage system;
processing an energy storage system status of the subordinate energy storage system utilizing a processing unit of the subordinate energy storage system;
articulating one or more battery contactors within the subordinate energy storage system;
processing a battery contactor status of the one or more battery contactors within the subordinate energy storage system utilizing the processing unit;
determining a status of a plurality of energy storage systems; and
transmitting the status of the plurality of energy storage systems to the processing unit of the first energy storage system.

12 . An energy storage system comprising:
at least one contactor configured to be coupled to at least one corresponding battery module; a power conversion module configured to be coupled to a power source at a first connection and the at least one battery module at a second connection; and a battery management system configured to be coupled to the at least one contactor and the power conversion module, and configured to:
energize the at least one battery module;
articulate the at least one contactor;
process a contactor status of the at least one contactor to detect contactor errors;
disengage the at least one battery module responsive to not detecting any battery contactor errors; and
determine a status of the energy storage system.

13 . The energy storage system of claim 12 , wherein the battery management system is further configured to process an energy storage system status to detect one or more system errors.

14 . The energy storage system of claim 13 , wherein the battery management system is further configured to correct, autonomously in response to detecting the one or more system errors, the one or more system errors.

15 . The energy storage system of claim 14 , further comprising a circuit breaker, wherein the battery management system is further configured to command, autonomously in response to detecting the one or more system errors, the circuit breaker to reset.

16 . The energy storage system of claim 13 , wherein the battery management system is further configured to articulate the at least one contactor responsive to not detecting one or more system errors.

17 . The energy storage system of claim 12 , wherein processing the contactor status includes detecting at least one stuck battery contactor.

18 . The energy storage system of claim 17 , wherein the battery management system is further configured to command, autonomously in response to detecting the at least one stuck battery contactor, the at least one stuck battery contactor to reset.

19 . The energy storage system of claim 12 , wherein the battery management system is configured to engage a mechanism to couple the at least one battery module to the energy storage system.

20 . The energy storage system of claim 12 , further comprising a system level controller and at least one connection configured to be coupled to a subordinate energy storage system, and wherein the system level controller is configured to:
transmit energy from the energy storage system to the subordinate energy storage system; process an energy storage system status of the subordinate energy storage system; articulate one or more battery contactors within the subordinate energy storage system; process a battery contactor status of the one or more battery contactors within the subordinate energy storage; and determine a status of a plurality of energy storage systems.
