Benefits of technology

[0006]A method for cooling a battery system utilizing a cooling system in accordance with another exemplary embodiment is provided. The cooling system has a housing, a first evaporator, a first evaporator fan, and a condenser. The housing has a first enclosed portion and a second enclosed portion. The first enclosed portion is configured to receive a first battery module therein. The method includes recirculating air in a first closed flow path loop within the first enclosed portion utilizing the first evaporator fan. The first evaporator is configured to extract heat energy from the air in the first closed flow path loop to reduce a temperature level of the first battery module in the first enclosed portion of the housing. The method further includes receiving heat energy in a refrigerant from the first evaporator in a condenser disposed in the second enclosed portion of the housing and dissipating the heat energy utilizing the condenser. The method further includes recirculating the refrigerant through the first evaporator and the condenser utilizing a compressor disposed in the second enclosed portion.

Embodiment Construction

[0020]Referring to FIGS. 1-3, a power generation system 10 for outputting electrical power in accordance with an exemplary embodiment is illustrated. The power generation system 10 includes a battery system 20 and a cooling system 22.

[0021]The battery system 20 is provided to output electrical power. The battery system 20 includes the battery modules 24, 26. Each of the battery modules 24, 26 has a similar structure and includes a plurality of battery cell assemblies that can be electrically connected in series to one another or in parallel to one another. For purposes of brevity, only a portion of the battery cell assemblies in the battery module 24 will be described in detail. For example, referring to FIGS. 8-10, the battery module 24 includes battery cell assemblies 28, 29, 30, 31, 32, 33, 34, 36, 38, 40 and 42 and flow channel manifolds 60, 62, 64, 66, 68, 70, 72, 74, 76 and 78. Each of the battery cell assemblies has a battery cell therein that generates an operational voltage...

Abstract

A cooling system for a battery system and a method for cooling the battery system are provided. The cooling system includes a housing having first and second enclosed portions, and a first evaporator and a first evaporator fan disposed in the first enclosed portion that recirculates air in a first closed flow path loop within the first enclosed portion. The first evaporator extracts heat energy from the air in the first closed flow path loop to reduce a temperature level of a first battery module in the first enclosed portion. The cooling system further includes a condenser disposed in the second enclosed portion and fluidly coupled to the first evaporator, which receives heat energy in a refrigerant from the first evaporator and dissipates the heat energy. The cooling system further includes a compressor disposed in the second enclosed portion that recirculates the refrigerant through the first evaporator and the condenser.

Description

TECHNICAL FIELD[0001]This application relates to a cooling system for a battery system and a method for cooling the battery system.BACKGROUND OF THE INVENTION[0002]In a typical air-cooled battery pack, ambient air from ambient atmosphere is directed across battery cells in the battery pack and is subsequently exhausted from the battery pack. However, the typical air-cooled battery pack has a major challenge in maintaining a temperature of the battery pack within a desired temperature range.[0003]In particular, a maximum operating temperature of the battery cells can often be less than a temperature of ambient air utilized to cool the batteries. In this situation, it is impossible to maintain the battery cells within a desired temperature range in an air-cooled battery pack.[0004]Accordingly, the inventors herein have recognized a need for an improved battery cell assembly that minimizes and / or eliminates the above-mentioned deficiency.SUMMARY OF THE INVENTION[0005]A cooling system f...
