1. A thermal management system for a motor vehicle, comprising:
a motor circuit in which at least one drive motor, a first connection, a radiator, a second connection, and a motor-circuit pump are arranged in series;
a battery line comprising a chiller and, in series therewith, a bypass/battery parallel connection with a traction battery and with a battery bypass parallel thereto, wherein the chiller is configured to be flowed through from a refrigeration circuit fluidically separated from the battery line,
wherein the first connection is arranged in the motor circuit downstream of the drive motor and upstream of the radiator, and wherein the first connection comprises a first valve device configured to selectively introduce coolant into the battery line,
wherein the second connection is arranged downstream of the radiator and upstream of the drive motor, and wherein the second connection comprises a second valve device configured to selectively:
conduct coolant to the drive motor; and/or
connect the chiller and the traction battery to form a ring-like battery circuit,
a third connection between the battery line and the motor circuit, wherein the chiller is arranged in the battery line between the first connection and the third connection,
wherein a first radiator bypass is configured to be formed via the third connection, the battery bypass, and the second connection; and
a second radiator bypass that branches off from the motor circuit downstream of the drive motor and upstream of the radiator and opens into the motor circuit downstream of the radiator and upstream of the drive motor.
