1. A temperature control system for an electric vehicle, comprising:
a cabin temperature control system configured to control flow of a refrigerant through one or more heat exchangers to control a temperature of a cabin of the electric vehicle;
a battery temperature control system configured to control the flow of a coolant through a plate heat exchanger to control a temperature of a battery system of the electric vehicle; and
a power electronics temperature control system configured to control a flow of coolant through one or more heat exchangers to control a temperature of one or more power electronics,
wherein, in a first configuration of the temperature control system, the battery temperature control system and the power electronics temperature control system are thermally isolated, and, in a second configuration, the battery temperature control system and the power electronics temperature control system thermally interact wherein in a first cooling mode the battery temperature control system is cooled using only the plate heat exchanger, and
wherein in a second cooling mode the battery temperature control system is cooled by both the plate heat exchanger and at least one of a plurality of inside air heat exchangers.
