  • Publication number: 20250062706
    Abstract: A forced discharge apparatus for a high-voltage component may include a component unit connected to a power supply unit through a connector. The forced discharge apparatus may also include a forced discharge circuit connected between the power supply unit and the component unit. The forced discharge apparatus may also include a control unit configured to discharge the component unit through the forced discharge circuit such that a voltage of the component unit becomes below a target voltage in response to a detection that a back electromotive force generated from the component unit when the connector is separated.

  • Patent number: 11904656
    Abstract: A heat pump system control method for a vehicle includes a process (A) of operating a compressor of an air conditioner to cool or heat an interior of the vehicle while the vehicle is driving, measuring by a controller initial states of the compressor and a refrigerant based on data detected from a data detector, and monitoring the compressor, a process (B) of determining by the controller whether a current coil temperature of a motor unit provided in the compressor is higher than a coil specification temperature through the process (A) and operating a protection mode; and a process (C) of, when the process (B) is completed, calculating by the controller a slope of a coil temperature of the motor unit over time, determining whether the temperature slope is greater than zero (0) three times consecutively to stop the operation of the compressor, and terminating control.
