Abstract
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.
