摘要： A vehicle includes an energy storage system (ESS) rechargeable using electrical power from an off-board AC power supply, a traction power inverter module (TPIM), one or two motors, and a controller. The TPIM has two inverters. The controller energizes designated semiconductor switches of the TPIM and designated induction coils of the motor to boost electrical power from the AC power supply for charging the ESS when the vehicle is not running. With two motors, a contactor allows induction coils of a first motor to be connected to the switches of the first inverter as an input filter, and an additional semiconductor switch is positioned between the ESS and an output side of the switches of the second inverter. A controller charges the ESS by energizing designated semiconductor switches of the TPIM and induction coils of the motor to charge the ESS without using an onboard battery charger module.

摘要： A vehicle includes a rechargeable energy storage system (RESS), an electric traction motor, a traction power inverter module (TPIM), a high-voltage direct current (HVDC) bus that electrically connects the RESS to the TPIM, a passive discharge circuit connected across the positive and negative rails of the bus, and a microprocessor. The circuit includes a semiconductor switch. The microprocessor provides an output signal at a first voltage level that opens the switch and prevents discharge of the HVDC bus when the microprocessor is operating normally, and at a default second voltage level that closes the switch in the presence of a predetermined vehicle condition to thereby discharge the HVDC bus. An optocoupler may receive the output signal, and a zener diode may be in electrical parallel with an output side of the optocoupler. The switch may be an insulated gate bipolar transistor or a thyristor in different embodiments.

摘要： A vehicle includes a motor, an alternating current (AC) power bus, a power inverter module (PIM), and a controller. The PIM includes a semiconductor die assembly with semiconductor power switches arranged in electrical parallel for delivering AC power to the motor via the bus. The controller determines an operating mode of the vehicle, selects and activates a designated one of the switches during a threshold low-current state of the PIM, and selects and activates all of the switches during a high-current state of the PIM. A PIM assembly for the vehicle includes the die assembly and controller. A method for optimizing energy efficiency of the vehicle includes providing the die assembly noted above, automatically determining the operating mode, and selecting and activating one of the switches when the operating mode corresponds to the threshold low-current state, and all of the electrical switches during the threshold high-current state of the PIM.

摘要： A high-voltage discharge circuit diagnostic system includes a high voltage DC link with a positive DC link and a negative DC link, a first resistor selectably connectable between the positive DC link and the negative DC link, and a second resistor connected between the positive DC link and the negative DC link. A control module connects the first resistor between the positive DC link and the negative DC link until the high voltage DC link discharges to a first voltage after which the control module disconnects the first resistor from between the positive DC link and the negative DC link to permit continued discharge of the high voltage DC link through the second resistor to a second voltage through an elapsed time period. The control module diagnoses a fault in the second resistor based upon the first voltage, the second voltage, and the elapsed time period.
