The invention provides an integrated expansion kettle, a heat management system and an electric vehicle, and belongs to the technical field of electric vehicles. The integrated expansion kettle comprises a kettle body, a multi-way valve, a channel set and a water pump set, wherein the multi-way valve is fixedly arranged at the bottom of the kettle body and partially extends into the kettle body, and the channel set and the water pump set are fixedly arranged on the kettle body. The channel set comprises seven independent channels, and the independent channels are communicated with an inner cavity of the multi-way valve and the outside of the kettle body. The water pump set comprises three water pumps, water inlets of the water pumps are directly communicated with the independent channels in a one-to-one mode, and one to two independent channels are distributed among the water pumps. The multi-way valve is used for changing the communication state of the independent channels. The length and the number of pipelines of the heat management system can be reduced, heat loss can be reduced, the performance of the heat management system is improved, and the assembly and maintenance difficulty can be reduced.
