Device for reduction of moisture in interior of housing of power unit e.g. lithium-ion battery used in motor vehicle, has first port fluidly connected to pressure vessel for introducing low moist working fluid into interior of housing

摘要

The device (1) comprises an electro-mechanical valve (20) having a first port (22) and a second port (24), in which the second port is fluidly connected with the first port at the entrance opening (16) of the housing (12) of the power unit (14). The first port is fluidly connected to a pressure vessel (26) for introducing low moist working fluid from the pressure vessel into the interior (10) of the power unit housing. A fluid dryer (28) is fluidically arranged in the pressure vessel. An independent claim is included for a battery.
