1. A thermal management system (2) for use in a vehicle, comprising:
a first cooling circuit (4) for cooling a battery (10); and
a second cooling circuit (6) for cooling an electric motor (12) configured to drive the vehicle,
wherein the first and second cooling circuits (4, 6) are configured to be connected to each other in three separate configurations comprising:
(a) in series by a multi-way valve (14) in a first mode of the thermal management system (2) and in a first valve position of the multi-way valve (14),
(b) in parallel in a second mode of the thermal management system (2) and in a second valve position of the multi-way valve (14), and
(c) in a third mode of the thermal management system (2) and in a third valve position, the multi-way valve (14) takes up an intermediate position in which coolant flows of the first and second cooling circuits (4, 6) are mixed with each other as needed.
