International Classification:

B60H 1/32
B60H 1/00

Abstract:

A vehicle system is described that includes a multi-phase rotary electric motor rotatably coupled via a rotatable member to an air-conditioning compressor, and a remotely located rechargeable energy storage system (RESS). The RESS includes a first power inverter that is electrically coupled to the multi-phase rotary electric motor via a plurality of electric power cables, a second power inverter that is electrically coupled to a second electric machine, a DC power source, and a chiller. A controller is in communication with and controllably coupled to the first power inverter and the second power inverter. The controller is operative to control the first power inverter to operate the multi-phase rotary electric motor in an open-loop control scheme.

Abstract:

A temperature regulation system for a battery is provided. The temperature regulation system includes an electrochemical cell, which may be in the form of a battery. The electrochemical cell includes a housing having a first side surface that extends from a first end to a second end, and a first temperature control chamber containing a dielectric fluid. The first temperature control chamber is located along the first side surface of the housing or along at least one of the first end or the second end of the housing. The dielectric fluid is in direct contact with the housing at the first side surface or at the first end or the second end.
