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.
Claims20
A vehicle power system for a vehicle, comprising:
- 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.
A method of controlling a power system for a vehicle, comprising:
- receiving power, by a coil in a first operational mode, wirelessly from an external source;
- transferring power from the coil to a first battery while the coil is in the first operational mode;
- charging a second battery with power from the first battery;
- and
- switching the coil from the first operational mode to 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.
