  • Patent number: 11878606
    Abstract: A battery thermal management system for a vehicle having a drivetrain. The thermal management system includes: a high-voltage propulsion battery, a waste-heat source of the vehicle drivetrain, and a battery heating circuit configured for circulating a battery coolant. The battery heating circuit includes a pipe being routed in the vicinity of, and spaced-apart from, the waste-heat source and configured for conveying the battery coolant for enabling the battery coolant within the pipe to heat-up by heat-radiation emitted from the waste-heat source and/or heat-convection through air from the waste-heat source to the battery coolant, and the battery heating circuit is configured for conveying the heated battery coolant to the battery for enabling heating of the battery by the battery coolant.

  • Publication number: 20220260137
    Abstract: A method for performing rotational speed synchronisation of a first transmission component having a first initial rotational speed with a second transmission component having a second initial rotational speed, by means of a three-phase AC electric motor that is rotationally connected to the first transmission component, during a gear switch in a stepped gear transmission of a drive train having a switching mechanism enabling the stator windings of the AC electric motor to be selectively connected in star configuration or delta configuration. The method includes obtaining a command, or determining, that a gear switch should be performed; shifting the stator winding configuration of the AC electric motor to delta configuration, or ensuring that the stator winding configuration of the AC electric motor is in delta configuration; and controlling operation of the AC electric motor for accomplishing rotational speed synchronisation of the first and second transmission components.
