Devices such as vehicles, remote sensors, and so forth consume energy during operation. Described herein are systems, devices, and methods for transferring energy from an uncrewed autonomous vehicle to a vehicle such as a car. The uncrewed autonomous vehicle may locate the vehicle at a rendezvous location, and connect with the vehicle while the vehicle moves. Once the uncrewed autonomous vehicle connects to the vehicle, the uncrewed autonomous vehicle may transfer the energy to the vehicle.
