摘要： A method is provided for impedance-controlled fast charging of a stored electrical energy source of a working device, in particular of a stored energy source in a vehicle. In the method: a variable characteristic of an impedance of the stored energy source is detected; a present charging current for charging the stored electrical energy source is set as a function of the variable characteristic of the impedance; the present charging current is temporarily reduced with a steep edge by temporarily connecting a resistive load to the stored energy source and feeding the load using the stored energy source; and a voltage response of the stored energy source to the steep edge is detected as the variable characteristic of the impedance of the stored energy source and is used as the basis for setting the present charging current.

摘要： A diagnostic method and a diagnostic system for an electrochemical energy storage cell, and a vehicle including the diagnostic system. An electrical current due to an electrical connection between the energy storage cell and a central load is modulated at a first excitation frequency and is measured centrally. An electrical voltage at the energy storage cell is measured and a first impedance value is determined based on the electrical current and the electrical voltage. Also, a previously-known electrical current due to an electrical connection between the energy storage cell and a predefined cell-individual load is modulated at a second excitation frequency. The electrical voltage occurring at the energy storage cell is measured and a second impedance value is determined based on the previously-known electrical current and the electrical voltage. Diagnostic information is determined and output based on a comparison of the first impedance value with the second impedance value.

摘要： A heating device for a prismatic battery cell of a high-voltage battery of a motor vehicle includes two sheet-shaped heating elements to be arranged on two opposite lateral outer sides of a cell housing of the battery cell, and two connecting elements to be arranged on a housing cover of the cell housing. The connecting elements are electrically connected to terminals of the two heating elements. The connecting elements are flexibly formed, at least in certain regions, and as a result the heating elements are connected in a hinge-like manner. The heating device can be arranged by arranging the first heating element on the first lateral outer side of the cell housing, swinging the second heating element over the housing cover, and arranging the second heating element on the second lateral outer side on the cell housing.

摘要： A safety switch device connects a heating unit for at least one battery cell of a high-voltage battery of a motor vehicle to a power supply connection that provides a heating current for the heating unit. The device includes: a first controllable switching element arranged in a heating current transmission path, which is designed to receive a control signal supplied by a unit external to the high-voltage battery via a signal transmission path of the safety switch device and to generate heating current transmission between the heating unit and the power supply connection according to the received control signal; a separating unit arranged in the heating current transmission path, for interrupting the heating current transmission in the event of failure of the first switching element; and a transmission unit arranged in the signal transmission path, which is designed to transmit the control signal potential-free to the first switching element, for the galvanic separation of the high-voltage battery and the unit.
