Abstract

An induction charging device for a vehicle charging system may include a housing, a cooling device, a magnetic field conductor unit, at least one induction coil, and at least one heat conductance device. The magnetic field conductor unit may be configured to direct a magnetic field. The at least one induction coil may be configured to wirelessly transfer energy with a predetermined transmission power. The at least one heat conductance device may be arranged, with respect to an axial axis, between at least two components. The at least one heat conductance device may have an axial thermal conductivity with respect to the axial axis. The axial thermal conductivity of the at least one heat conductance device may vary at least partially with respect to at least one lateral axis that is aligned at least one of substantially perpendicularly and substantially transversely to the axial axis.
