Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery drying device is fully integrated into the battery housing, then the device structure is compact and space-efficient, but the device complexity increases and maintenance becomes more difficult
Solution Approach 1:
The battery drying device is segmented into a removable drying agent container and a housing integrated into the battery. This allows the drying function to be compact when installed while enabling easy removal for maintenance and replacement of the drying agent, thus resolving the contradiction between compact integration and maintenance difficulty.
2Productivity
If the drying agent continuously adsorbs moisture from the battery housing, then moisture removal efficiency is maintained, but the drying agent becomes saturated and requires regeneration, reducing operational duration
Solution Approach 1:
The system implements periodic action by allowing the drying agent to adsorb moisture during normal operation and then regenerating it at scheduled intervals or when saturation is detected. This periodic adsorption-regeneration cycle maintains continuous moisture removal efficiency while extending the overall operational duration of the drying system.
3Reliability
If the heating device is used to regenerate the drying agent, then moisture can be released from the drying agent, but energy consumption increases during the regeneration process
Solution Approach 1:
The system applies parameter changes by using controlled heating at specific temperature thresholds to trigger moisture release from the drying agent. By optimizing the heating temperature and duration parameters, the system achieves effective regeneration while minimizing energy consumption, thus resolving the contradiction between regeneration reliability and energy use.
4Productivity
If the connection opening allows free airflow between the drying housing and battery housing, then moisture can be efficiently removed, but liquid water can enter the battery housing, reducing safety
Solution Approach 1:
The connection opening is equipped with a membrane that acts as a selective barrier. This thin film structure allows gaseous moisture to pass through via diffusion and pressure equalization while blocking liquid water entry. This resolves the contradiction by maintaining efficient moisture removal through the membrane while preventing harmful liquid water ingress into the battery housing.

Implementation Method 1
An inlet opening (6) is provided in the drying housing (5), which is covered by a membrane (7) that keeps out liquid, in particular water, but could be permeable to water in the gaseous state
Implementation Method 2
A moisture adsorber means (10) is arranged in the flow path between the inlet opening (6) and the connecting opening (8)
Implementation Method 3
A heating device (11) is integrated into the moisture adsorber means (10), by means of which the moisture adsorber means (10) can be heated and adsorbed moisture can be released

AI summary
A battery drying device includes a membrane disposed external to a battery housing of a battery, and configured to prevent liquid water from passing through the membrane and to allow gaseous water to pass through the membrane, a moisture adsorber means disposed external to the battery housing and downstream from the membrane, and configured to absorb moisture in the gaseous water, and an adjustable connection valve disposed adjacent to the battery housing and downstream from the moisture adsorber means, and configured to, in a regular operation mode, be open and allow air from which the moisture is absorbed by the moisture adsorber means into the battery housing, and in a regeneration mode, be closed. The battery drying device further includes an adjustable regeneration valve interposed between the membrane and the moisture adsorber means.
