Abstract

A collection of computer software algorithms that ascertain the operational state of a vehicle'"'"'s starter battery.

Claims

2. A computer algorithm that measures the instantaneous voltage drop that occurs when an engine is started and uses this information along with the starting temperature and a history of previous start operations to ascertain the robustness of the starter battery.

1. A collection of computer algorithms that ascertain the operational state of a vehicle'"'"'s starter battery based upon claims 2-6.

3. A computer algorithm that measures the time to start an engine and uses this information along with the starting temperature and a history of previous start operations to ascertain the robustness of the starter battery.

4. A computer algorithm that measures the charge state of a starter battery based upon voltage, time from previous start operation and the battery'"'"'s temperature.

5. A computer algorithm that approximates a starter battery'"'"'s temperature based upon information read from a remote sensor.
