Abstract: Methods and systems for predicting a potential alternator failure in a motor vehicle are provided. The method includes determining a potential alternator undercharging condition if a duration between the maximum cranking voltage time stamp and the maximum device voltage time stamp is greater than an undercharging indicator duration threshold. Advantageously, an alternator may be repaired or replaced before it fails thus averting having the motor vehicle become inoperable.

Abstract: Methods and systems for determining an alternator condition in a motor vehicle are provided. The method includes receiving a maximum cranking voltage and a maximum cranking voltage time stamp from the motor vehicle over an asset interface of the telematics device; receiving a maximum device voltage and a maximum device voltage time stamp from the motor vehicle over the asset interface, and determining a potential alternator undercharging condition if a duration between the maximum cranking voltage time stamp and the maximum device voltage time stamp is greater than an undercharging indicator duration threshold. Advantageously, an alternator may be repaired or replaced before it fails thus averting having the motor vehicles inoperable.

Abstract: Devices and systems for determining an alternator condition in a motor vehicle are provided. The method includes performing a plurality of micro wakeups to capture voltage values during a cranking event, determining the maximum cranking voltage and its timestamp, detecting an ignition signal, determining the maximum device voltage and its timestamp, and determining a potential alternator undercharging condition if a duration between the maximum cranking voltage timestamp and the maximum device voltage timestamp is greater than an undercharging indicator duration threshold. Advantageously, an alternator may be repaired or replaced before it fails thus averting having the motor vehicles inoperable.
