A coolant system for an electric vehicle having first and second heat generating components includes a fluid circuit that circulates a coolant therethrough and a coolant assembly. The coolant assembly decreases the temperature of a portion of the coolant to a first temperature and supplies the portion of coolant to the first heat generating component via a first supply branch of the fluid circuit, and decreases the temperature of a remaining portion of the coolant to a second temperature and supplies the remaining portion of coolant to the second heat generating component via a second supply branch of the fluid circuit. The system includes a first pump unit, arranged downstream of the coolant assembly in the first supply branch, that directs the portion of coolant to the first heat generating component, and a second pump unit that directs the remaining portion of coolant to the second heat generating component.
