1. A system for charging a vehicle, the system comprising:
a charging depot including a plurality of vehicle charging spaces, a vehicle charging space of the plurality of vehicle charging spaces comprising a longitudinal direction, along which a vehicle maneuvers when pulling into the vehicle charging space, and a lateral direction perpendicular to the longitudinal direction;
a first vehicle charging space of the plurality of vehicle charging spaces, the first vehicle charging space comprising a first offboard charging coil and a second offboard charging coil that are configured to substantially simultaneously induce current in onboard charging coils of a first vehicle and that are spaced apart from one another by a first distance in a first lateral direction of the first vehicle charging space; and
a second vehicle charging space of the plurality of vehicle charging spaces, the second vehicle charging space comprising a third offboard charging coil and a fourth offboard charging coil that are configured to substantially simultaneously induce current in onboard charging coils of a second vehicle and that are spaced apart from one another by a second distance, which is in a second lateral direction of the second vehicle charging space and is greater than the first distance.
