International Classification:

B60H 1/00
B60H 1/22
B60H 1/26
B60L 58/26
B60H 1/32

Abstract:

A vehicle thermal management system includes a vehicle heat pump system, a battery system coolant loop, a drive train coolant loop, and control electronics. The vehicle heat pump system includes a compressor, a cabin condenser, a cabin evaporator, a cabin blower, and a chiller. The battery system coolant loop is in thermal communication with a battery system and with the chiller and selectively in thermal communication with the drive train coolant loop. The control electronics control the components of the vehicle thermal management system to heat the cabin, cool the cabin, heat the battery system, cool the battery system, and cool the drive train. The control electronics may control the compressor to operate in an efficient mode or a lossy mode in which the compressor generates heat. The control electronics may also control the components of the vehicle thermal management system to precondition the battery.

International Classification:

F16K 11/085

Abstract:

A multi-port, multi-mode valve includes: a valve housing; multiple ports on the valve housing, a spacing between first and second ports being smaller than a spacing between third and fourth ports; and a stemshell positioned at least partly inside the valve housing, the stemshell having at least two channels configured for selectively coupling one or more of the ports to a selected at least other one of the ports.
