Description

Although the present invention has been illustrated and described in detail in the drawings and the preceding description, this description should be understood as illustrative rather than restrictive, and is not intended to limit the present invention to the disclosed embodiments. The fact that certain feature elements are described in different dependent claims does not in any way mean that combinations of those features cannot be used advantageously. While this application pertains to the invention described in the claims, the disclosure of this application also includes the following: 1. A prime mover circulation path (3) is provided, in which at least one drive prime mover (10), a first connection part (4), a heat sink (6), a second connection part (7), and a prime mover circulation path pump (9) are arranged in series. A battery line (19) comprising a chiller (21) and a bypass battery parallel circuit having a traction battery (24) and a battery bypass (25) in parallel with the traction battery in series with the chiller, wherein the chiller (21) has a battery line through which the flow of the cooling circuit (2) can pass while being separated from the battery line (19), The first connection portion (4) in the prime mover circulation path (3) is located downstream of the drive prime mover (10) and upstream of the heat sink (6), and the first connection portion (4) allows for the selective introduction of coolant into the battery line (19) using the first valve device (5). The second connection portion (7) is located downstream of the heat sink (6) and upstream of the drive motor (10), and a second valve device (8; 408) is located at the second connection portion (7), and the chiller (21) and the traction battery (24) can be connected using the second valve device to selectively pass coolant toward the drive motor (10) and/or to form an annular battery circuit (33). A third connection point (29) is provided between the battery line (19) and the prime mover circulation path (3), and the chiller (21) is positioned in the battery line (19) between the first connection point (4) and the third connection point (29). The third connection portion (29), the battery bypass (25), and the second connection portion (7) can form the first heat sink bypass (31). In automotive thermal management systems, It has a second heat sink bypass (32), which branches off from the motor circulation path (3) downstream of the drive motor (10) and upstream of the heat sink (6), and connects to the motor circulation path (3) downstream of the heat sink (6) and upstream of the drive motor (10). A thermal management system characterized by the following features. 2. The thermal management system according to claim 1, wherein an electric heater (20) is located in the battery line (19). 3. The thermal management system according to 1 or 2 above, wherein the second heat sink bypass (32) has no heat sink or heat source. 4. The heat management system according to any one of the above 1 to 3, wherein the second heat sink bypass (32) is connected to the second connection (7). 5. The thermal management system according to any one of the above 1 to 4, wherein a battery pump (22) is further arranged in the battery line (19). 6. The thermal management system according to any one of 1 to 5, further comprising a condenser line (17) extending between the second connection part (7) and the first connection part (4), wherein the condenser line (17) comprises a condenser (18), and the condenser (18) is separated from the condenser line (17) through which the flow of the cooling circuit (2) can pass. 7. The second valve device (8) is equipped with at least three switching positions, In the first switching position, the battery line (19) is connected in series with the drive motor (10). In the second switching position, the chiller (21) and the bypass battery parallel circuit are connected to form a closed, ring-shaped battery circuit (33), and the second heat sink bypass (32) is disconnected. In the third switching position, the chiller (21) and the bypass battery parallel circuit are connected to form a closed, ring-shaped battery circuit (33), and the second heat sink bypass (32) is connected in series with the drive motor (10). A thermal management system as described in any of items 1 to 6 above. 8. An automobile having a thermal management system as described in any of items 1 to 7 above.
