METHOD FOR CHECKING A CONNECTION BETWEEN A LOW-VOLTAGE SUPPLY SYSTEM AND A BATTERY, AND MOTOR VEHICLE |
摘要 |
Method for checking a connection between a battery (2) which supplies a low-voltage supply system (1) of a motor vehicle (12), the voltage of said low-voltage supply system being lower than the voltage of a high-voltage supply system (6) of the motor vehicle (12), and the low-voltage supply system (1), wherein a DC voltage converter (5) which is designed to interchange electrical energy between the high-voltage supply system (6) and the low-voltage supply system (1) connects the high-voltage supply system (6) to the low-voltage supply system (1), wherein the DC voltage converter (5) modulates the output voltage into the low-voltage supply system at a modulation frequency, wherein the current impressed by this and the voltage impressed by this are measured by the battery (2), and a resistance value is determined and evaluated with respect to at least one connection criterion according to which a connection fault is identified when at least one connection criterion is not fulfilled. |
