The invention is directed to an automotive coolant supply device (10; 10'), with a traction battery coolant supply chamber (14) and a separate traction motor coolant supply chamber (16), and a flow restrictor element (20; 20') fluidically connecting the traction battery coolant supply chamber (14) and the traction motor coolant supply chamber (16) within the automotive coolant supply device (10; 10'), wherein the flow restrictor element (20; 20') defining a connection passage (25; 25') within a separating wall (12) being arranged between the traction battery coolant supply chamber (14) and the traction motor coolant supply chamber (16). The flow restrictor element (20; 20') provides a relatively low coolant and heat exchange between the coolant supply chambers (14, 16), but allows to applicate one single common coolant expansion reservoir for all coolant circuits of a battery electric vehicle.
