METHOD FOR OPERATING A CHARGE REGULATOR FOR AN ELECTRICAL ACCUMULATOR IN A MOTOR VEHICLE

The invention relates to a method for operating a charge regulator (LR, 40) for an electrical accumulator (S), particularly a battery (B) of a motor vehicle on-board power supply (100), which can be supplied with electrical energy by means of an electrical machine (30) that can be coupled to an inte...

Zusammenfassung:	The invention relates to a method for operating a charge regulator (LR, 40) for an electrical accumulator (S), particularly a battery (B) of a motor vehicle on-board power supply (100), which can be supplied with electrical energy by means of an electrical machine (30) that can be coupled to an internal combustion engine (112) in a direct or geared manner and comprises a rotor (32) and a stator (33) with at least one phase winding (U, V, W) producing phase signals (UU, UV, UW, lU, lV, lW), in which at least one value (WUu, WUd, WVu, WVd, WWu, WWd) is detected, which occurs at least once per revolution of the rotor (32) and is associated with at least one rising edge (FlUu, FlVu, FlWu) of the phase signal (UU, UV, UW, lU, lV, lW) or falling edge (FlUd, FlVd, FlWd) of the phase signal (UU, UV, UW, lU, lV, lW), and once a first nominal value (Usoll1) of the electrical accumulator (S) has been reached or exceeded, the charge regulator (LR) is controlled such that, following the occurrence of the at least one value (WUu, WUd, WVu, WVd, WWu, WWd), a current flow (I) from the electrical machine (30) into the electrical accumulator (S) is stopped. The invention also relates to a corresponding arithmetic unit which is configured for carrying out the method, and to a computer program for carrying out the method.
