Claim 14:
15. A data center, comprising:
a lithium ion based battery coupled to information technology (IT) equipment; and
a cooling system having a primary cooling system, a secondary cooling system and a controller, wherein the controller is configured to perform operations, the operations including:
determining that the lithium ion based battery is inactive, and
in response to the lithium ion based battery being inactive,
a) maintaining, while the battery is inactive, a temperature of the battery at or below an optimal storage temperature of the battery the primary cooling system, wherein the optimal storage temperature of the battery is determined based on selecting from a plurality of storage temperatures each of which having computed a sum of i) a cost associated with a power consumption used to cool the battery, and ii) a cost associated with a degradation of a capacity of the battery, wherein the optimal storage temperature is selected from the plurality of storage temperatures based on having a lowest sum among the sums computed for the plurality of storage temperatures, and
b) in response to determining that the primary cooling system does not decrease the temperature of the battery, maintaining the temperature of the battery at or below the optimal storage temperature of the battery with the secondary cooling system which includes a compressor, while the battery is inactive.
