    摘要： A new energy vehicle, a vehicle-mounted charging device, a temperature measurement circuit, and a temperature measurement method. The circuit comprises: a first temperature sensor (TH1), which acquires a first analog quantity temperature signal of a positive electrode connection terminal; a second temperature sensor (TH2), which acquires a second analog quantity temperature signal of a negative electrode connection terminal; a third temperature sensor (TFH), which is provided in a housing of the vehicle-mounted charging device of the new energy vehicle and acquires an analog quantity ambient temperature signal of the vehicle-mounted charging device of the new energy vehicle; an analog-to-digital conversion module (10), which correspondingly converts the first analog quantity temperature signal, the second analog quantity temperature signal, and the analog quantity ambient temperature signal into a first digital quantity temperature signal, a second digital quantity temperature signal, and a digital quantity ambient temperature signal; and a micro-control unit (20), which corrects the first digital quantity temperature signal and the second digital quantity temperature signal according to the digital quantity ambient temperature signal. The accuracy of measuring the charging temperature of the vehicle-mounted charging device of the new energy vehicle can be improved.

    摘要： The present invention relates to a system (10) for monitoring a switchgear, the system comprising:
    - at least one temperature sensor (20);
    - a processing unit (30); and
    - an output unit (40).
    The at least one temperature sensor is configured to acquire temperature data for each location of at least one location of a switchgear (50) at n time points. The at least one temperature sensor is configured to provide the temperature data to the processing unit. The processing unit is configured to determine n-1 rates of change of temperature for one or more locations of the at least one location with respect to the n temperature data for the one or more locations at the n time points. The processing unit is configured to determine a state of the switchgear, wherein the determination of the state of the switchgear comprises utilization of the n-1 rates of change of temperature for the one or more locations and at least n-1 of the n temperature data for the one or more locations. The output unit is configured to output the determined state of the switchgear when the determined state of the switchgear is determined not to be normal or not to be healthy.
