Abstract
A vehicle, system and method of charging the vehicle. The vehicle includes a battery, a first electric motor coupled to the battery, a second electric motor coupled to the battery, and a switch for forming a circuit between a charging station and the battery through the first electric motor and the second electric motor. A processor controls a configuration of the switch and commences charging of the battery from the charging station through the first electric motor and the second electric motor.
Claims20
A method of charging a vehicle, comprising:
- forming a circuit between a charging station and a battery of the vehicle through a first electric motor of the vehicle and a second electric motor of the vehicle, wherein forming the circuit includes connecting the first electric motor of the vehicle to a battery disconnect unit via a first inverter and the second electric motor of the vehicle to the battery disconnect unit via a second inverter, wherein the battery disconnect unit includes a plurality of switches able to be configured in any one of a plurality of operational modes including a normal mode of operation, a first (standard) charging mode, and a second (increased power) charging mode, and wherein the plurality of switches in the battery disconnect unit can be reconfigured from any one of the plurality of operational modes to any other one of the plurality of operational modes;
- and
- charging the battery from the charging station through the first electric motor and the second electric motor.
A system for charging a battery of a vehicle, comprising:
- a first electric motor coupled to the battery;
- a second electric motor coupled to the battery;
- a battery disconnect unit connecting the first electric motor to the battery via a first inverter and the second electric motor to the battery disconnect unit via a second inverter, wherein the battery disconnect unit includes a plurality of switches able to be configured in any one of a plurality of operational modes including a normal mode of operation, a first (standard) charging mode, and a second (increased power) charging mode, and wherein the plurality of switches in the battery disconnect unit can be reconfigured from any one of the plurality of operational modes to any other one of the plurality of operational modes
- the plurality of switches forming a circuit between a charging station and the battery through the first electric motor and the second electric motor;
- and a processor configured to:
- control a configuration of the switch;
- and
