Abstract
Wirelessly charging a vehicle battery may be performed using a plurality of charging coils. The offboard coils and the onboard coils may be spaced apart by different amounts, such that, when the vehicle is positioned in a vehicle charging space, at least one pair of an onboard coil and an offboard coil may still be substantially aligned for wireless charging, even when other coils are misaligned. The offboard coils may include sizes that are conducive to charge smaller capacity systems in some arrangements and are combinable to charge larger capacity systems in other arrangements. In addition, the use of relatively small coils may allow for flexibility in thermal management.
