Vehicle platforms and thermal management systems, subsystems, and components for use therewith are described. Thermal management architectures and systems incorporate thermal management cycles for one or more of drive train, energy storage and passenger cabin systems. Thermal manage architectures are provided such that the flow of heating and cooling fluids through such thermal management cycles may be combined in various configurations. Systems having thermal management cycles for drive train (e.g., motor, transmission, etc.) and energy storage (e.g., battery) that may be operated through a combined heating/cooling fluid loop are also provided. Embodiments are also directed to systems having thermal management cycles for the HVAC that is fluidly isolated, but thermally coupled to one or both of the drivetrain and energy storage components. Heating/cooling loops for these thermal management cycles may be functionally linked through one or more valves such that the fluid flow through such cycles may be combined together, isolated from each other or mixed in various desired configurations.
