NOVELTY - The condensing system has a condensing device (70), which is arranged in a battery interior (30) and is in fluid communication with cooling fluid that enters a battery interior through inlet opening arranged in battery housing (20), and which causes moisture present in battery interior and stemming from environment to condense. The condensed moisture emerges into environment through an outlet opening (60) arranged on battery housing. Battery cells (40) are arranged in the battery housing which surrounds the battery interior.    USE - Condensing system for battery in motor vehicle (claimed) used on land, such as automobile, on water, and/or in air.    ADVANTAGE - The battery which is operating is cooled and moisture present in the battery interior, which enters the battery interior from the environment and is unwanted, is condensed in a targeted manner at a specific, uncritical location in the battery interior and discharged from the battery interior, and that it is possible to avoid condensed water from being deposited on battery cells and to avoid corrosion on battery cells or short circuit between the battery cells. An already existing cooling unit of e.g. air conditioning system, can be used as cooling unit of condensing device. The cooling or condensing unit can be additionally cooled by relative wind which strikes the cooling or condensing unit during movement of vehicle, if condensing unit is arranged within battery interior and/or cooling unit is arranged outside battery interior in a region which faces forward direction of travel of vehicle. The condensing device is surrounded by porous material, such that condensing device is in physical contact with the porous material, thus, moisture stored in porous material can assist the cooling process by virtue of evaporative cooling, resulting in reduced energy requirement for cooling of battery.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for condensing moisture in vehicle battery.
