Abstract
Apparatus, device, methods and system relating to a vehicular telemetry environment for monitoring vehicle components and providing indications towards the condition of the vehicle components and providing optimal indications towards replacement or maintenance of vehicle components before vehicle component failure.
Claims10
A method of monitoring a battery of a vehicle, the method comprising:
- receiving a plurality of voltage signals indicating a change in voltage of the battery at times associated with a plurality of crankings of a starter motor of the vehicle;
- determining, for each of the plurality of voltage signals, a maximum voltage and a minimum voltage of the voltage signal, to generate a plurality of maximum voltages and a plurality of minimum voltages for a time period;
- determining a variance in the plurality of minimum voltages for the time period;
- generating a prediction of a state of the battery based at least in part on the plurality of maximum voltages, the plurality of minimum voltages, and the variance of the plurality of minimum voltages.
