Abstract

The embodiment of the application provides a wireless charging substrate, a ground charging device and a vehicle-mounted charging device. A region obtained by connecting internals of the adjacent coils in a coil layer in the wireless charging substrate is the region with centrally distributed magnetic field energy, when a coverage region of a ferrite layer is corresponding to the region obtained by connecting internals of the adjacent coils in the coil layer, the ferrite layer can transmit the magnetic field energy produced by the coils more uniform and centralized, thereby realizing efficientwireless charging process.

Description

technical field [0001] The present application relates to the technical field of wireless charging, in particular to a wireless charging substrate, a ground charging device and a vehicle charging device. Background technique [0002] At present, the wireless charging system mainly includes off-vehicle power supply, ground charging substrate (Base pad, BPpad for short), vehicle charging substrate (Vehicle pad, VP pad for short), VCU (Vehicle control unit, vehicle control unit) and vehicle battery pack, etc. Among them, the VP pad and the BP pad form a coupling and achieve good charging when a certain coupling coefficient is satisfied. Ground charging substrates and vehicle charging substrates mainly include aluminum plates, ferrite and double D-shaped coils. When charging, one of the D-shaped coils of the ground charging substrate transmits the magnetic field energy generated after power-on to the other D-shaped coil through the ferrite, and then transmits it to the ground c...
