- the particles W3 in which the cooling water is vaporized are cooled in the cooler 141 and liquefied.
- the cooling water W1 liquefied in the cooler 141 flows into the cooling water tank 145 .
- the cooling water is firstly recovered from the charging housing 120, and the cooling water remaining on the outer surface of the battery pack 100 is vaporized and recovered, and the cooling water injected into the charging housing is recovered. can be recovered as much as possible. As a result, loss of cooling water can be prevented, and maintenance costs of the battery pack cooling device can be reduced.
- the cooling water on the surface of the battery pack can be completely removed.
- cooling water is firstly recovered from the charging housing, and the cooling water remaining on the outer surface of the battery pack is vaporized and secondarily recovered, so that the cooling water introduced into the charging housing can be recovered as much as possible.
