Abstract
A method for operating a battery sensor and a battery sensor, including a first and second battery sensor connections, load current connection, current measurement device for recording load current, and first and second measuring resistor elements. The first and second measuring resistor element series connected between the load current connection and the second battery sensor connection, a reference current circuit with at least one reference resistor. The reference resistor in contact with the first battery sensor connection and a contact point between the measuring resistor elements. The electrical resistance of the first resistor element determined by switching on the reference current and recording the voltage drops across the first and second measuring resistor element and the battery voltage, determining the reference current from the battery voltage quotient and electrical resistance of the reference resistor element, and determining the electrical resistance of the first resistor element from the recorded voltage drops.
