    摘要: The invention relates to a multi-voltage on-board power supply system for a motor vehicle having a hybrid or electric drive, comprising a dc-dc converter (DCDC), by means of which a high voltage level having a higher direct current different from earth and at least one first energy store (ES1) is connected to a low voltage level having a lower voltage different from earth and at least one second energy store (ES2). The multi-voltage on-board power supply system comprises a charging interface (S) for charging external devices. At least one converter phase of the dc-dc converter can be disconnected from the low voltage level and instead can be connected to the charging interface, and a third energy store (ES3) can be connected to the charging interface in order to supply the third energy store in the connected state with the lower voltage and to enable charging of the third energy store by energy flow from the first energy store to the third energy store.

    摘要: The invention relates to an energy-storage element diagnostic circuit for a cell group in a cell composite of an energy storage element, in particular an energy storage element in a motor vehicle electric system, said diagnostic circuit being connected to voltage terminals of the cell group. In said circuit, a specific voltage level and/or current is impressed upon a diagnostic conductor, which can then be used for the interrogation of at least one monitored operating parameter of the cell group and/or cell composite, if a cell group voltage at the voltage terminals of the cell group exceeds a first threshold level and/or if the cell group voltage fails to reach a second threshold level. A regeneration method is carried out on the basis of such flags, said method distinguishing whether or not a cell is defective.
