Abstract
A vehicle may include a vehicle charging system having an alternator operatively coupled to an engine and a controller. The controller may be programmed to output a warning indicative of a vehicle charging system fault in response to a quotient of a voltage drop associated with the alternator and an output current of the alternator exceeding a threshold value while the alternator is operating in a steady state condition.
Claims20
A method of detecting a vehicle charging system fault comprising:
- in response to a quotient of a voltage drop associated with an alternator and an output current associated with the alternator exceeding a threshold value while the alternator is operating in a steady state condition, outputting for display a warning indicative of a vehicle charging system fault.
A method of monitoring a vehicle charging system comprising:
- outputting an alert indicative of a vehicle charging system fault in response to a connector resistance exceeding a threshold while a battery is under charge, wherein the connector resistance is based on an engine speed, an excitation current associated with a generator, and a difference between a voltage associated with the generator and a voltage associated with a power distribution point.
A vehicle comprising:
- a vehicle charging system having an alternator operatively coupled to an engine;
- and
- a controller programmed to output a warning indicative of a vehicle charging system fault in response to a quotient of a voltage drop associated with the alternator and an output current of the alternator exceeding a threshold value while the alternator is operating in a steady state condition.
