Abstract

The present invention relates to a cooling system for an electric power unit for a vehicle (1). The electric power unit comprises an electric machine (2), an electric energy storage (4) for storing of electrical energy and power electronics (5) for controlling the flow of electrical energy between the electrical energy storage (4) and the electric machine (2): The cooling system comprises a high temperature cooling circuit (6) with a circulating coolant configured to cool the power electronics (5) and a low temperature cooling circuit (21) with a circulating coolant configured to cool the electric energy storage (4). The coolant cooling system is configured, at ambient air temperatures below a specific temperature, to cool the coolant in the high temperature cooling circuit (6) in a first radiator (8a) and the coolant in the low temperature cooling circuit (21) in a second radiator (8b). The coolant cooling system is configured, at ambient air temperatures above said specific temperature, to cool the coolant in the high temperature cooling circuit (6) in the first radiator (8a) and in the second radiator (8b), and to cool the coolant in the low temperature cooling circuit (21) by means of a refrigeration system (18).
