Integrated conductance and load test based electronic battery tester
First Claim
1. An electronic battery tester for testing a storage battery comprising:
- a first Kelvin connection configured to electrically couple to a first terminal of the battery;
a second Kelvin connection configured to electrically couple to a second terminal of the battery;
a forcing function configured to apply a time varying signal to the battery through the first and second Kelvin connections;
a load resistance RL configured to couple across the first and second terminals of the battery and draw a relatively large current therethrough; and
a microprocessor configured to test the storage battery as a function of a dynamic parameter measured through the first and second Kelvin connections in response to applied time varying signal and as a function of a response of the storage battery to the relatively large current drawn through the load resistance.

Abstract
An electronic battery tester for testing a storage battery includes first and second Kelvin connections configured to couple to the battery. A forcing function applies a time varying signal to the battery through the first and second Kelvin connections. Further, a resistive load is configured to couple across the first and second terminals of the battery and draw a relatively large current. The storage battery is tested as a function of a dynamic parameter measured through the first and second Kelvin connections and as a function of a response of the storage battery to the relatively large current drawn through the resistive load.
