Abstract

A vehicle power supply system and method may include plural vehicle contacts extending along a vehicle. At least three of the vehicle contacts may be power contacts that receive different phases of three-phase alternating current electrical power from an off-board power supply system to power the vehicle. A first power contact of the power contacts may receive a first phase of the three-phase alternating current and a second power contact of the power contacts may receive a second phase of the three-phase alternating current while the vehicle has a first orientation relative to the off-board power supply system. The first power contact may receive the second phase and the second power contact may receive the first phase while the vehicle has a second orientation relative to the off-board power supply system.

Dependent claims

A vehicle power supply system comprising:

plural vehicle contacts extending along a top side of a vehicle, the plural vehicle contacts including at least three power contacts configured to receive electrical power from an off-board power supply system to power the vehicle, each of the power contacts configured to receive a different phase of three-phase alternating current of the electrical power,
a first power contact of the power contacts configured to receive a first phase of the three-phase alternating current and a second power contact of the power contacts configured to receive a second phase of the three-phase alternating current while the vehicle has a first orientation relative to the off-board power supply system, and
the first power contact configured to receive the second phase of the three-phase alternating current and the second power contact configured to receive the first phase of the three-phase alternating current while the vehicle has a second orientation relative to the off-board power supply system, the second orientation opposite the first orientation.

Dependencies are inferred from the claim text.
