Vehicle power network management

A power distribution device, comprising:

• one or more memories;
• and
• one or more processors communicatively coupled to the one or more memories and configured to:
• obtain an engine speed of an engine, an alternator speed of an alternator, and a pulley ratio associated with the engine and the alternator;
• calculate a belt slip value of a belt coupled to the engine and the alternator based on at least one of the engine speed, the alternator speed, or the pulley ratio;
• detect a belt slip of the alternator based on the belt slip value and a slip threshold value;
• and
• decrease, in response to detecting the belt slip, a voltage setpoint of a converter connected to the alternator from an initial voltage setpoint to a target voltage setpoint.

A non-transitory computer readable medium including instructions stored therein that, when executed by one or more processors of a power distribution device, cause the one or more processors to:

• obtain an engine speed of an engine, an alternator speed of an alternator, and a pulley ratio associated with the engine and the alternator;
• calculate a belt slip value of a belt coupled to the engine and the alternator based on at least one of the engine speed, the alternator speed, or the pulley ratio;
• detect a belt slip of the alternator based on the belt slip value and a slip threshold value;
• and
• decrease, in response to detecting the belt slip, a voltage setpoint of a converter connected to the alternator from an initial voltage setpoint to a target voltage setpoint.
