The present invention relates to a wireless charger for charging a high voltage (HV) battery of a vehicle, comprising: a coil configured to wirelessly receive an oscillating magnetic field from an external transmitter, thereby generating an alternating current (AC); a ferrite disposed adjacent to the coil; a cooling channel disposed adjacent to at least one of the ferrite and the coil, the cooling channel configured to provide a flow of coolant; an electrical component configured for charging the HV battery based on AC; a metal cover separating the coil and the ferrite from the electrical components, at least one of the electrical components being disposed adjacent to the metal cover, where the wireless charger further includes a non-conductive portion configured to at least partially form a cooling channel and to separate the coil and the ferrite from the metal cover.

    本发明涉及一种用于对车辆的高压(HV)电池进行充电的无线充电器,包括:线圈,其被配置用于无线地接收来自外部发射器的振荡磁场,从而产生交流电流(AC);铁氧体,其邻近线圈布置;冷却通道,其邻近铁氧体和线圈中的至少一个布置,该冷却通道被配置用于提供冷却剂流;电气部件,其被配置用于基于AC对HV电池充电;金属盖,其将线圈和铁氧体与电气部件分离,电气部件中的至少一个与金属盖邻近布置,其中,无线充电器进一步包括被配置用于至少部分地形成冷却通道并且将线圈和铁氧体与金属盖分离的非导电部分。
