摘要： The disclosure relates to a method for charging an intermediate circuit capacitor in an electric drive unit comprising an electric motor. The intermediate circuit capacitor is charged by an intermediate circuit current that is supplied by a battery. The output voltage of the battery is settable to one or more voltage values. A target value of the intermediate circuit current is determined, and an actual value of the intermediate circuit current is ascertained. The actual value of the intermediate circuit current is then compared with the target value of the intermediate circuit current. An optimal output voltage of the battery is determined on the basis of the comparison of the actual value of the intermediate circuit current with the target value of the intermediate circuit current. Then, the optimal output voltage of the battery is set.

摘要： The disclosure relates to a method for detecting a triggering of a security device. The security device is associated with a battery cell and is triggered if a security-critical situation is present in the battery cell. Initially an actual time path of a parameter of the battery cell is detected. At the same time, an expected time path of the parameter is determined, in particular using a model. Then, the actual time path is compared to the expected time path of the parameter. Finally, based on the comparison, it is determined whether to trigger the security device or not.

摘要： The invention relates to a traction battery having at least two serially connected battery modules, each of which has a first battery module pole, a second battery module pole, and at least one inserted series circuit and/or parallel circuit of battery cells. A first terminal of the series circuit of battery modules is connected to a first battery pole, while a second terminal of the series circuit of battery modules is connected to a second battery pole. According to the invention, at least one battery module of the at least two serially connected battery modules is a first battery module which has a first disconnecting device, a second disconnecting device, and a bridging device. When triggered accordingly, the first disconnecting device interrupts the connection between the series circuit and/or parallel circuit of battery cells and the first battery module pole, and when triggered accordingly, the second disconnecting device interrupts the connection between the series circuit and/or parallel circuit of battery cells and the second battery module pole. Furthermore, the first battery module pole and the second battery module pole are short-circuited via the bridging device inserted between the first battery module pole and the second battery module pole when the bridging device is triggered accordingly. Additionally or alternatively, at least one battery module of the at least two serially connected battery modules is a second battery module that has at least one charging and disconnecting device, a disconnecting device, and a bridging device. When triggered accordingly, the at least one charging and disconnecting device interrupts the connection between the series circuit and/or parallel circuit of battery cells and the first battery module pole and limits charging or compensating currents occurring when the battery module or the battery comprising the battery module is connected. Furthermore, when triggered accordingly, the interrupting device interrupts the connection between the series circuit and/or parallel circuit of battery cells and the second battery module pole, and the first battery module pole and the second battery module pole are short-circuited via the bridging device inserted between the first battery module pole and the second battery module pole when the bridging device is triggered accordingly.
