A GPU output from a ground power unit (GPU) can be converted to power suitable for starting a jet engine of an aircraft by an auto-transformer rectifier unit (ATRU) of the aircraft. Multiple ATRUs, each connected to a corresponding GPU, may output multiple ATRU outputs, and combining these multiple ATRU outputs can generate a combined power, which can satisfy the power requirements for starting a jet engine when they exceed what can be supplied by a single GPU. The combining is possible when the outputs of the ATRUs are synchronized, which can require generating and sharing a sync signal between the ATRUs that is synchronous with an ATRU designated as the master (i.e., reference) for the other ATRUs.

An aircraft adaptive battery charging system is provided. The adaptive battery charging system comprises: a battery system; a bidirectional converter, wherein the bidirectional converter is capable of an inverter mode and a rectifier mode; an alternating current (AC) motor; a number of controllable contactors that control electrical current between the battery system, bidirectional converter, AC motor, and a power source wherein the controllable contactors can be switched between a closed position to allow electrical current flow and an open position to prevent electrical current flow; a motor controller; a battery charging system controller configured to send control signals to the battery system, motor controller, and controllable contactors in response to system command signals; and a vehicle system controller that sends system command signals to the motor controller and battery charging system controller.

A system comprises a smart building with a vertiport zone and a complex zone; and a managing device. The managing device is configured to: establish movement route information, of the aerial mobility device in the vertiport zone, based on management information associated with a transport object or flight of the aerial mobility device. If the movement route information indicates to move to at least one designated area of the vertiport zone and a charging permission condition is satisfied, the movement route information is set to add a charging site as a layover point. The aerial mobility device is controlled to move to the charging site according to the set movement route information and to be charged. If the movement route information indicates to move to the complex zone, the aerial mobility device is controlled to move to an exit area of the vertiport zone approaching the complex zone.
