Embodiment Construction

[0023] It should be appreciated that the drawings and description of embodiments of the charge transport system have been simplified to explain pertinent elements for clarity of understanding, while many other elements found in typical vehicle systems have not been depicted for the sake of brevity. Those skilled in the art may recognize that other elements and / or steps are desirable and / or necessary to practice the invention. However, since such elements and steps are well known in the art, and because they are not conducive to a better understanding of the present invention, a discussion of such elements and steps is not provided here.

[0024] The non-limiting embodiments described herein relate to charge transport systems. The charge transport system can be modified for various applications and uses within the spirit and scope of the claims. The embodiments and variations described herein and / or shown in the drawings are given by way of example only, and not limiting in sc...

Abstract

A charge transfer system includes an on-board vehicle motor system and a plug in supply. The on-board vehicle motor system includes a first motor including a plurality of stator windings, a second motor including a plurality of stator windings, a first inverter having a plurality of switch legs, a second inverter having a plurality of switch legs, a controller, and an on-board power supply. The plug-in supply is connected between at least one switch leg of the first inverter and at least one switch leg of the second inverter. The controller modulates the switch legs of the first and second inverters such that electric current flows through at least one stator winding of the first or second motor to charge the on-board power supply. The current flow can also alternate in phase with plug-in supply polarity to produce a stable stator flux vector angle preventing motor rotation during charge transfer.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 61 / 939,968, filed February 14, 2014, and U.S. Formal Application No. 14 / 562,399, filed December 5, 2014, which are incorporated by reference as if fully set forth. technical field [0003] The present invention relates generally to systems for recharging electrical storage devices, and more particularly to systems for discharging or supplying power from electrical storage devices mounted, for example, on vehicles. Background technique [0004] Many plug-in hybrid electric vehicles (PHEVs) have two electric motors. One motor may typically be used for traction and the other for power generation. There are other auxiliary motors in these vehicles (ie, air conditioning compressor and electric steering pump). These motors are typically three-phase permanent magnet motors, which are powered during operation by an on-board power source such as a battery...
