Abstract
A method for operating a buck converter as a power source for electronics of a battery system, includes: operating the buck converter in a first mode in which the buck converter provides a first output voltage; receiving a first control signal; and in response to receiving the first control signal, operating the buck converter in a second mode in which the buck converter provides a second output voltage for a System Basis Chip of the battery system. The first output voltage has a first value in a range of a to b, and the second output voltage has a second value in the range of c to d, wherein b is less than c.

A method for operating a buck converter as a power source for electronics of a battery system, the method comprising:
- operating the buck converter in a first mode in which the buck converter provides a first output voltage;
- receiving a first control signal;
- and
- in response to receiving the first control signal, operating the buck converter in a second mode in which the buck converter provides a second output voltage for a System Basis Chip of the battery system,
- wherein the first output voltage has a first value in a range of a to b, and the second output voltage has a second value in a range of c to d, wherein b is less than c.
A battery system comprising:
- a plurality of battery cells;
- a buck converter comprising:
- a first input terminal connected to a first potential provided by the plurality of battery cells;
- a second input terminal connected to a feedback circuit;
- and
- an output terminal configured to output an output voltage;
- and
- a battery management circuit configured to be connected to the output terminal via a first switch,
- wherein the feedback circuit comprises a second switch connected in series to a first resistor, the second switch being configured to electrically connect the second input terminal to a second potential, and
- wherein the feedback circuit further comprises a third switch connected in series to a second resistor, the third switch being configured to electrically connect the second input terminal to the second potential.
