Abstract
A power supply system can exchange electricity with a vehicle. The power supply system may include a first circuit rated at a lower first voltage that can provide the electricity to a starter battery and/or an auxiliary load onboard the vehicle. The system also can include a second circuit rated at a higher second voltage and that can provide the electricity to a propulsion battery capable of powering one or more traction motors of the vehicle.
Claims20
A power supply system configured to exchange electricity with a vehicle, the power supply system comprising:
- a first circuit rated at a lower first voltage and configured to provide the electricity to one or both of a starter battery or an auxiliary load onboard the vehicle;
- and
- a second circuit rated at a higher second voltage and configured to provide the electricity to a propulsion battery capable of powering one or more traction motors of the vehicle.
A power supply system configured to receive electricity supplied to a vehicle, the power supply system comprising:
- a first circuit and a second circuit each coupled to an alternating current (AC) bus;
- a plurality of power converter and battery pairs, with each of the power converters coupled to the alternating current bus and configured to convert alternating current from the alternating current bus to direct current (DC) and to supply the direct current to the respective battery.
A charging system configured to supply electricity to a vehicle, the charging system comprising:
- connectors configured to mate or couple with corresponding first and second vehicle connectors;
- a continuity circuit configured to mate or couple third and fourth vehicle connectors with each other and with a power supply system onboard a vehicle;
- a ground circuit that, when complete, electrically couples the power supply system of the vehicle to a ground reference that is off-board the vehicle.
A system, comprising:
- an external charger configured to supply electricity to a power supply system onboard a vehicle via connectors on a first lateral side or first end of the vehicle;
- a ground wire configured to couple the power supply system with a ground reference of an off-board charging system;
- and
- a continuity jumper configured to mate with and connect connectors on a second lateral side of the vehicle that is opposite the first lateral side or on a second end of the vehicle that is opposite the first end of the vehicle.
