Energy storage system, cooling system, and related method

A method of controlling a temperature of an energy storage system, the energy storage system comprising:

• a storage container having:
• an enclosed compartment containing:
• one or more energy storage units and an enclosed compartment duct;
• an inverter cabinet containing an inverter, the inverter cabinet having one or more inverter cabinet inlets;
• and
• an inverter exhaust duct;
• and
• a transformer bay containing a transformer at a position laterally spaced from the enclosed compartment;
• and
• an air temperature control unit, attached to the storage container and configured to circulate conditioned air to the enclosed compartment via the enclosed compartment duct and to the inverter cabinet via the one or more inverter cabinet inlets, and to return air from the enclosed compartment and the inverter cabinet via an air temperature control unit return,
• the method comprising:
• starting flow of the conditioned air from the air temperature control unit;
• circulating the conditioned air through the enclosed compartment via the enclosed compartment duct such that the enclosed compartment duct receives the conditioned air and supplies the conditioned air to an interior of the enclosed compartment;
• circulating the conditioned air through the inverter cabinet via the one or more inverter cabinet inlets;
• and
• returning air that has passed through the one or more energy storage units in the enclosed compartment and air that has passed through the inverter cabinet and is exhausted by the inverter exhaust duct to the air temperature control unit via the air temperature control unit return.

A cooling system for an energy storage system, the energy storage system having:

• an enclosed compartment containing one or more energy storage units and an inverter cabinet containing an inverter;
• and
• a transformer bay containing a transformer,
• the cooling system comprising:
• an air temperature control unit, attached to the storage container and configured to output conditioned air and to return air from the enclosed compartment;
• an enclosed compartment duct, located in the enclosed compartment near the one or more energy storage units, and configured to receive the conditioned air from the air temperature control unit;
• one or more inverter cabinet inlets, located on a side of the inverter cabinet and configured to receive the conditioned air from the air temperature control unit;
• an inverter exhaust duct, located above the inverter cabinet, and configured to exhaust air from within the inverter cabinet back into the enclosed compartment;
• and
• an air temperature control unit return, configured to return air that has circulated through the one or more energy storage units in the enclosed compartment and air output by the inverter exhaust duct to the air temperature control unit.
