A charging amount calculation apparatus calculates an amount of power consumption by a battery for running along a running route and a during-running charging amount received by a power reception apparatus from at least one second power feeding facility. The charging amount calculation apparatus calculates a pre-running charging amount based on the amount of power consumption and the during-running charging amount.

A ground power supply apparatus for transmitting power to a vehicle by noncontact has: a plurality of power transmission apparatuses for transmitting power to the vehicle; at least one detection device for detecting a signal emitted from the vehicle using narrow range wireless communication; and a controller for controlling the power transmission apparatuses. The power transmission apparatuses are arranged in a road aligned in a direction of advance of the vehicle. One first detection device is arranged so as to enable detection of the signal at an upstream side from the most upstream power transmission apparatus. The control device controls transmission of power from power transmission apparatuses other than the first power transmission apparatus positioned the most upstream, based on the signal detected by the first detection device and power transmission result information at the power transmission apparatus positioned upstream of that power transmission apparatus.

A charge control system includes a lithium battery configured to provide lithium battery power to a set of electrical loads, a user signaling device, and control circuitry coupled with the lithium battery and the user signaling device. The control circuitry is operative to: (A) detect availability of charge from an external charger, (B) in response to detection of the availability of charge from the external charger and prior to controlling the external charger to adjust the amount of charge stored by the lithium battery, perform a set of pre-charging assessment operations, and (C) based on the set of pre-charging assessment operations, provide a user notification via the user signaling device, the user notification indicating whether the lithium battery is properly setup for charge adjustment. When the user signaling device generates the user notification, the user is informed that the utility vehicle is properly connected to the external charger.

Systems and techniques are provided for charging devices at a property using battery-charging drones. In some implementations, a monitoring system is configured to monitor a property and includes a battery-powered sensor configured to generate sensor data. The system includes a drone that is configured to navigate the property and charge the battery-powered sensor. A monitor control unit is configured to obtain a battery level from the battery-powered sensor and compare the battery level to a battery level threshold. Based on the comparison, the monitor control unit determines that the battery level does not satisfy the threshold. Based on the determination, the monitor control unit generates and transmits an instruction to a drone for the drone to navigate to the battery-powered sensor and charge a battery of the battery-powered sensor. The monitor control unit receives data from the drone that indicates whether the drone charged the battery of the sensor.

A method for orienting a power receiving coil of a vehicle relative to a power emitting coil of a wireless charging system for a vehicle. The method includes detecting a positioning of the vehicle at a charging location in which the power receiving coil detects reception of electromagnetic radiation emitted from the power emitting coil, performing a calibration sequence in which the orientation of the power receiving coil and/or the power emitting coil is varied according to a predetermined scheme, while registering the electromagnetic radiation reception of the power receiving coil, in response to the calibrations sequence, determining a desired relative orientation including relative angle between the power receiving coil and the power emitting coil for which the electromagnetic radiation reception of the power receiving coil is in a top range of the registered electromagnetic radiation reception.
