| 摘要 |
The invention relates to an on-board power supply for a vehicle having - a first on-board power supply branch (2), wherein the first on-board power supply branch (2) has a first energy store (3), - a second on-board power supply branch (4), wherein the second on-board power supply branch (4) has a second energy store (5), - an electrical resistor (18), wherein the electrical resistor (18) can be electrically coupled to a first connection (9) of the second energy store (5), - a voltage identification unit (20), wherein the voltage identification unit (20) is designed to identify - a first voltage value of a voltage of the second energy store (5), if the electrical resistor (18) is electrically disconnected from the first connection (9) of the second energy store (5) and to identify a second voltage value of the voltage of the second energy store (5), if the electrical resistor (18) is electrically coupled to the first connection (9) of the second energy store (5), - an internal resistance identification unit (21), wherein the internal resistance identification unit (21) is designed to identify a resistance value characterizing an internal resistance of the second energy store (5). |
