A modular air conditioning system for an electric vehicle is configured as an integrated module that performs in-vehicle air-cooling, in-vehicle air-heating, and battery cooling. The modular air conditioning system includes a dash panel making a division of the vehicle into a power electric (PE) system room in which a PE system for the vehicle is provided and a passenger compartment in which an occupant rides, and a housing provided to pass through the dash panel, wherein a heating and cooling module that supplies conditioned air to the passenger compartment, cools a battery for the electric vehicle, or cools the PE system is provided inside the housing.

A thermal management system includes a cooling liquid circulation flow path, a refrigerant circulation flow path and a first heat exchanger. The first heat exchanger includes a first heat exchange portion and a second heat exchange portion. The cooling liquid circulation flow path includes a first heat exchange assembly, a second heat exchange assembly and a first branch. The thermal management system has a heating mode. After passing through the first heat exchange assembly, one path of the cooling liquid flows to the first branch, and another path of the cooling liquid flows to the second heat exchange assembly. The cooling liquid after flowing through the first branch and after flowing through the second heat exchange assembly merge and then flow to the first heat exchange portion. As a result, the number of heat exchangers used by the thermal management system to recover waste heat is reduced.

A heat pump vehicle thermal system comprises a battery pack thermal system, a two-phase refrigeration system, and a power electronics thermal system. When the outer environment is cold relative to the interior of the vehicle (cold ambient), the heat pump thermal system is controlled in a first mode where the two-phase refrigeration system transfers heat generated by the power electronics thermal system to either the battery pack thermal system or to the cabin or to both. When the outer environment is hot relative to the interior of the electric vehicle (hot ambient), the heat pump thermal system is controlled in a second mode where the two-phase refrigeration system absorbs heat from the battery pack thermal system and the cabin and transfers the absorbed heat to the ambient environment. In the second mode, no heat generated by the power electronics is transferred to either the cabin or the battery packs.
