Abstract
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.
Claims13
A coolant system for an electric vehicle for circulating a liquid coolant, the coolant system comprising:
- a plurality of components through which the coolant is adapted to flow, the components being connectable to each other, at least in at least one subset, in a coolant-conducting manner with the aid of valves and with the aid of coolant lines;
- and
- a single multi-way valve and a single non-return valve being arranged such that one of the components and another of the components are fluidically connectable to each other only with the aid of a further component designed as a coolant pump and 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 a rest of the components.
