  • Patent number: 11376983
    Abstract: A traction battery charging station for charging a traction battery of a motor vehicle having an electric traction motor. The charging station includes a converter that feeds DC voltage into a pair of two charging lines during charging operation, a charging controller, and an insulation monitor having two measuring resistors that are each connected to a charging line and are able to be connected to protective earth via a respective resistor switch. The insulation monitor monitors the electrical insulation of the pair of charging lines with respect to protective earth during non-charging and during charging of the traction battery. A test mode controller has a non-restricted non-charging test mode in which one resistor switch is closed and the other resistor switch is open at the same time, and a symmetric charging test mode in which both resistor switches are closed at the same time or open at the same time.

  • Publication number: 20220190627
    Abstract: A method is provided for controlling a charging device (1) for charging energy stores (2). A charging electronics system (6) has a power electronics system (7). A cooling device (9) has at least one first temperature sensor (12) for ascertaining the temperature of a barrier layer of a power semiconductor in the power electronics system (7), at least one second temperature sensor (13, 14) for ascertaining the temperature of the coolant, means for determining input power and output power of the charging electronics system (6). At least the first temperature sensor (12) is monitored to ascertain a rate of change of the temperature of the barrier layer of the power semiconductors. The power loss of the charging electronics system (6) is controlled to limit the rate of change of the temperature of the barrier layer to ensure that a maximum temperature of the barrier layer is not exceeded.

  • Patent number: 11117485
    Abstract: A method for charging an energy storage element of a vehicle using a charging apparatus which provides a charging current (IL) and a charging voltage (U) at an operating point. The charging apparatus has a plurality of energy supply modules connected in parallel, having the following method steps: in an optimization step, a distribution of the charging current (IL) to the energy supply modules connected in parallel, in the case of which the charging apparatus has a maximum overall efficiency, is respectively determined for a plurality of predefined operating points; in a charging step which follows the optimization step, a distribution of the charging current (IL) to the individual energy supply modules of the charging apparatus, in the case of which the charging apparatus has a maximum overall efficiency, is selected on the basis of a predefined charging current (IL) and a predefined charging voltage (U).
