Thermal management system and vehicle

A vehicle having a thermal management system comprising:

• a first coolant circuit for a battery;
• a second coolant circuit for an electric motor configured to drive the vehicle;
• a multi-way valve configured to operate the first and second coolant circuits:
• in a first mode and in a first valve position of the multi-way valve, the first and second coolant circuits in series with one another or
• in a second mode and in a second valve position of the multi-way valve, the first and second coolant circuits in parallel with one another or
• in a third mode and in a third valve position of the multi-way valve, in which the multi-way valve assumes an intermediate position in which coolant flows of the first and second coolant circuits are mixed with each other as needed;
• an oil cooling circuit for additionally cooling the electric motor;
• and
• a heat exchanger that thermally connects the oil cooling circuit to the second coolant circuit.
