  • the present disclosure relates batteries and systems for cooling such batteries, and more particularly to a battery cooling system having a thermoelectric module and phase change material heat exchanger to cool batteries used to power electronic equipment, and related methods of cooling batteries.
  • Batteries are frequently used in power devices, such as uninterruptible power supplies.
  • the heat dissipated during use of such batteries, as well as during charging of the batteries, may lead to an increase in battery surface temperature, which can have severe effects on the life expectancy and performance of the batteries.
  • Performance issues and increased battery failure occur at higher ambient temperatures, which may increase warranty costs.
  • the batteries become too hot during use, battery life may be drastically reduced. Also, if the battery is too cold, it may be required to warm the batteries before charging. Thus, it is desirous to maintain batteries within a desired temperature range for optimum performance as well as optimum charging. Another issue is with uniform cooling of the battery cells. For example, one cell may be at an increased temperature with respect to other cells of the battery. If one cell charges faster than other cells, this may cause a decline in the discharge and charging efficiency, which in turn could affect the performance of the batteries.
  • a conventional refrigeration system is bulky and less reliable as it has moving parts requiring maintenance and repair/replacement (e.g., a compressor).
  • Another approach is to apply a phase change material (PCM) as blanket around batteries by absorbing peak or cyclic loads for many applications. This approach causes design complexities in implementation.
  • Yet another approach is to cool the batteries by a cooling unit employing a vapor compression system, which is either all "ON” or all “OFF.” Thus, when using such a cooling unit, there is no proportionality, so full power must be applied at all times.
