Abstract

An induction charging device for an electrically operated motor vehicle may include an emission protection arrangement and a charging arrangement secured to the emission protection arrangement. The emission protection arrangement may include a metal shield plate. The charging arrangement may include a magnetic plate facing the emission protection arrangement, at least one induction coil disposed in a charging housing, and an active cooling arrangement secured in the charging housing to transfer heat. The magnetic plate may be at least one of (i) at least partially ferrimagnetic and (ii) at least partially ferromagnetic. On a housing bottom side, the charging housing may include at least one cooling recess for the active cooling arrangement. The active cooling arrangement may include at least one cooling duct formed integrally in the cooling recess. The charging arrangement may further include a bottom side cover secured in a fluid-tight manner to the housing bottom side.
