Device (100) for determining a coolant temperature of a cooling circuit (300), wherein the cooling circuit (300) is designed for sequential cooling of the power electronics of at least a first and a second electrical power component (510, 520). The device (100) is configured to receive and evaluate a signal that characterises the temperature of the power electronics of the switched-off second component (520) during operation of the first component (510), in order to determine the coolant temperature of the cooling circuit (300), and to receive and evaluate a signal that characterises the temperature of the power electronics of the switched-off first component (510) during operation of the second component (520), in order to determine the coolant temperature of the cooling circuit (300).
