US 2025/0145307 A1 · BATTERY DRIVEN GROUND POWER UNIT WITH IMPROVED CONSTRUCTION, OPERABILITY, DURABILITY AND MAINTENANCE

Abstract

An airport ground power unit for supplying electric current to a parked aircraft and a related system and method. The ground power unit includes a first electric battery, an inverter for transforming an output current of the battery to an alternating output current to be supplied to the aircraft, and one or more first electronic switches for connecting and disconnecting the first battery to and from the inverter. The first switches are connected in serial to the first battery, and together connected to the inverter. A first controller unit controls at least one of the one or more first switches. The ground power unit further includes a second electric battery and second electronic switches for connecting and disconnecting the second battery. At least one of the second switches is controlled by the first or a second digital controller unit.

Dependent claims

A system for supplying electric current to an aircraft parked on the ground, comprising:

a battery ground power unit (1) configured to supply electric current to an aircraft parked on the ground, the battery ground power unit (1) including one or more batteries (30, 31), and an inverter (50) for transforming an output current of the one or more batteries (30, 31) to an alternating output current of the inverter (50) to be supplied to the aircraft;
a helper ground power unit (1′) including an alternating current output connector (191′);
and
an alternating current input port (190, 390.2);
wherein the battery ground power unit (1) is configured to be connected to the alternating current output connector (191′) of the helper ground power unit (1′) via the alternating current input port (190, 390.2), in order to route an alternating output current of the helper ground power unit (1′) via the alternating current input port (190, 390.2) to the aircraft.
