  • Publication number: 20190223331
    Abstract: A monitoring apparatus has a control apparatus for monitoring a cooling apparatus for a power electronics arrangement. The control apparatus has an input and an output, which input is configured to receive a temperature signal from a temperature sensor, and to determine a temperature value depending on the temperature signal, and which output is configured to output an output signal. The control apparatus performs the following steps: ascertaining at least twice a temperature value and a time value assigned to the temperature value, ascertaining a difference quotient of the change in the temperature values to the change in the assigned time values, determining the state of the cooling apparatus of the power electronics arrangement depending on the ascertained difference quotient, outputting the output signal depending on the state in order to influence the power electronics arrangement.

  • Patent number: 10286791
    Abstract: A method for recognizing an over-temperature in a region of a charging socket of a motor vehicle without a temperature sensor. A temperature value is detected by means of a temperature sensor at an installation location of the temperature sensor that is different from the region. At least one configuration value of a current operating configuration in which the charging socket is operated is determined, and then a temperature reading for the region without the temperature sensor is generated by means of a characteristic map, which is designed for the purpose of including the temperature value and the at least one configuration value as input variables and of assigning the temperature reading to these input variables.

  • Publication number: 20190106007
    Abstract: A charging device for a vehicle is made available, which has two multi-pole connections, each of which can be coupled to a charging interface which is arranged on the vehicle. A power electronics module which is designed to convert alternating current into direct current is coupled to the two multi-pole connections. At least one measuring device which is designed to determine a parameter of the charging current is present at a pole of one of the two multi-pole connections during a charging process. An evaluation unit is coupled to the at least one measuring device and is designed to determine, on the basis of the parameter determined by the measuring device, whether the charging process is taking place by means of the first or by means of the second multi-pole connection.
