Cooling system and method for energy storage

An energy storage cooling system, comprising:

• at least one energy storage device;
• an ambient temperature sensor configured to generate an ambient temperature signal indicative of a temperature outside of the at least one energy storage device;
• a chiller system in fluid communication with the at least one energy storage device;
• a radiator system in fluid communication with the chiller system;
• a coolant circuit including a first flow portion for supplying coolant to the at least one energy storage device, a second flow portion for supplying the coolant to the chiller system, and a third flow portion for supplying the coolant to the radiator system such that an entirety of a coolant flow to the radiator system is received from the chiller system;
• and
• a controller configured to control an operation of the chiller and an operation of the radiator system based on the ambient temperature signal.

A method for temperature control of an energy storage system, the method comprising:

• supplying coolant from a chiller system within an interior of a housing of the energy storage system to control temperature of at least one energy storage device disposed within the housing, the housing of the energy storage system containing a radiator system and the chiller system;
• returning the supplied coolant to the chiller system;
• detecting an ambient temperature outside of the at least one energy storage device and outside of the housing of the energy storage system, the ambient temperature being a temperature associated with a location of the energy storage system;
• when the detected ambient temperature does not exceed a first ambient temperature threshold, activating a function of a radiator system and deactivating a function of the chiller system;
• and
• when the detected ambient temperature is greater than a second ambient temperature threshold that is higher than the first ambient temperature threshold, activating the function of the chiller system such that the function of the chiller system is activated at an ambient temperature that is different from an ambient temperature at which the function of the chiller system was deactivated.
