Abstract

Systems and methods are described herein for controlling heat flow between systems of an electric automotive vehicle. An automotive electric vehicle system includes a high voltage battery system including an enclosure, an electric powertrain system, a radiator, coolant lines that permit coolant flow between the high voltage battery system, the power train system and the radiator, one or more valves for routing coolant along the coolant lines, and a controller. The controller is configured to control the one or more valves to control the flow of coolant among a plurality of different, selectable coolant flow states involving the high voltage battery system, the powertrain system and the radiator.
