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 method for monitoring electric isolation of a high voltage DC bus to detect ground isolation faults includes monitoring voltage differentials between a positive DC electric power bus and a negative DC electric power bus and a chassis ground. Electrical isolation between each of the positive and negative DC electric power buses and the chassis ground is monitored using a ratio of the voltage differentials.

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.
