Abstract
A vehicle power system includes a coil that, in a first operational mode, receives power wirelessly from an external source, a first battery connected to the coil to receive power transferred from the coil while the coil is in the first operational mode, a second battery that receives power from the first battery, and a switch that switches the coil between the first operational mode and a second operational mode in which the coil receives power from the second battery and wirelessly transfers power from the second battery to an electrical load in the vehicle.
