| 摘要 |
<p>The present invention relates to an arrangement and a method to control the temperature of an electric energy storage system (2) in a vehicle (1). The arrangement comprises a line circuit (5) which comprises a valve element (7, 7a, 16, 16a) and at least two parallel conduits (5b, 5c, 5k) which are arranged in a position immediately upstream of the electric energy storage system (2). One of the parallel conduits (5b) comprises a heating device (8) and another of the parallel conduits (5 c) comprises a cooling device (9), The valve element (7, 7a, 16, 16a) is adapted to lead the medium through the parallel conduit (5b), which comprises the heating device (8), at operating times when the electric energy storage system (2) has a temperature below a lower threshold value (tj), and to lead the medium through the parallel conduit (5c), which comprises the cooling device (9), at operating times when the electric energy storage system (2) has a temperature above an upper threshold value (t2).</p> |
