Abstract: A heat exchange plate, a battery pack and a vehicle. The heat exchange plate comprises a first interface, a second interface, and a flow channel in communication with the first interface and the second interface. The heat exchange plate is configured to exchange heat for a battery, and the flow channel is configured to circle a working medium. When the heat exchange plate is used to cool the battery, the working medium flows into the flow channel from the first interface, and flows out from the second interface. When the heat exchange plate is used to heat the battery, the working medium flows into the flow channel from the second interface, and flows out from the first interface.
