  "textContent": "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.",
