COOLANT SYSTEM FOR AN ELECTRIC VEHICLE, AND THERMAL MANAGEMENT SYSTEM

A coolant system for an electric vehicle for circulating a liquid coolant, comprising a plurality of components through which the coolant can flow. The components can be connected to one another, at least in at least one subset, in a coolant-conducting manner via valves and via coolant lines. Only a single multi-way valve and a single non-return valve are arranged in such a way that one of the components and another of the components can be fluidically connected to one another only via a further component, designed as a coolant pump, and via a predetermined switching state of the multi-way valve to permit a flow through the multi-way valve and the non-return valve independently of the rest of the components. A thermal management system is also provided.
