Abstract: A thermal management system includes: a heat pump; an electric-powertrain water passage; an engine water passage; a first heat exchanger having a first heat exchange channel and a second heat exchange channel, and the first heat exchange channel being in communication with the heat pump; a battery cooling plate being in communication with the heat pump; and a control valve group being in communication with the electric-powertrain water passage, the engine water passage, and the second heat exchange channel. The control valve group is switchable between a first state and a second state. When the control valve group is in the first state, the engine water passage and the second heat exchange channel are in communication. When the control valve group is in the second state, the electric-powertrain water passage and the second heat exchange channel are in communication.
