Customer ServiceEstablished solutions for this are e.g. vents and units with semi-permeable mem-branes. As gas enters the battery system interior, humidity can also enter. If the surface temperature of e.g. cooling plates falls below the dew point, condensation on those cold surfaces inside the system will occur.
To verify the computational approach employed in the present study, simulations were conducted on the condensation of water vapor within a vertical pipe with a 10 % mass fraction of water vapor in the air in the serpentine flow of moist air, as described by Poškas R et al.
To avoid water condensation the absolute humidity inside the system must be kept at a level which will prevent the crossing of the dew point curve at the lowest temperature inside the battery system. At the dew point, the air is saturated with water, the curve showing a relative humidity of 100% is the dew point curve.

Calculation tools for product dimensioning were developed. 1. Motivation Climate change is one of the major threats to mankind.
Under this operating condition, the area of the condensation region accounts for 31.96 % of the total monitoring area. Compared to the original liquid-cooled battery thermal management system, the proportion of the condensation area has significantly decreased by 39.68 %.
3. Humidity control To reduce the system complexity, two important functions – pressure balancing and emergency degassing – are com-bined into one unit. The unit has to ensure that no liquid water can enter the battery housing under all conditions. A PTFE membrane was validated for this application.
