  • Publication number: 20140147709
    Abstract: A battery system having first and second battery cells and a cooling fin disposed between the first and second battery cells is provided. The cooling fin receives heat energy from the first and second battery cells and transitions a two-phase refrigerant into a gaseous refrigerant within an internal flow path. The compressor pumps the gaseous refrigerant into a condenser. The condenser transitions the gaseous refrigerant into the liquid refrigerant by extracting heat energy from the gaseous refrigerant.

  • Publication number: 20140120390
    Abstract: A battery cell assembly is provided. The assembly includes a cooling fin having a tube and a flexible thermally conductive sheet disposed on the tube. The tube has first, second, and third tube portions. The first and second tube portions are substantially perpendicular to one another. The third tube portion is substantially perpendicular to the first and second tube portions and extends between the first and second tube portions. The sheet is coupled to at least the first and second tube portions and has a first sheet portion extending between the first and second tube portions. The assembly further includes a battery cell disposed against the first sheet portion of the sheet of the cooling fin.

  • Publication number: 20130255293
    Abstract: A battery system and a method for cooling the battery system are provided. The system includes an evaporative cooling member, and a battery module having a housing, a battery cell, and a solid cooling fin. The housing holds the battery cell therein. The solid cooling fin has first and second panel portions. The first panel portion is disposed against the battery cell. The second panel portion extends through the housing and is disposed on the evaporative cooling member. The solid cooling fin conducts heat energy from the battery cell to the evaporative cooling member. The evaporative cooling member receives a gaseous-liquid refrigerant and transitions the gaseous-liquid refrigerant into a gaseous refrigerant utilizing the heat energy received from the solid cooling fin.

  • Publication number: 20130158913
    Abstract: A system and a method for determining charging and discharging power levels for a battery pack are provided. The battery pack has an enclosure holding a battery module therein. The system includes a computer that determines a temperature correlation value based on first and second temperature values associated with the battery pack. The computer determines a third temperature value indicative of a temperature level of a first battery cell disposed adjacent to the end of a housing in the battery pack based on the first temperature value and the temperature correlation value. The computer determines a desired charging power level for the battery pack based on the third temperature value.
