2 Electrochemical Characterizations of Battery Interfaces. Electrochemistry is by definition the science of interfaces. Thus, our understanding of the SEI, its chemical nature and physical properties, is closely related to advances made in the description of the electrochemical properties of battery interfaces.
Without running extensive discharge tests, conductance can be used to rapidly and safely determine a functional battery’s state-of-health. Together with other battery information, conductance can also be used to detect cell defects, shorts, and open circuits which can cause early battery failure.
With the battery conductance tester, personnel can save time and money with more accurate results, quickly identify battery health, and uncover potential problems before an actual emergency. Batteries fail due to buildup on charging plates. This buildup disrupts the flow of energy increasing the batteries resistance to charge.
Initial conductance value for the most batteries can be provided by the battery manufacturer. If the batteries conductance value is not available it can be reasonably established by using the average of 20 to 30 measured conductance values provided they are the same type of battery, date code and state of charge.
Make sure the CCA setting is identical to the rating of your battery. When connecting the battery conductance tester to the battery ensure the positive (+) clamp attaches to the positive terminal, and the negative (-) clamp connects to the negative terminal. Make sure both clamps grip the terminals. A poor connection will prevent testing.
The resultant conductance measurement provides pertinent battery information without the need of bringing the battery to full discharge. As a battery discharges, its conductance and capacity are reduced with a simultaneous drop in power in a predictable manner due to the depletion of conductive active materials.
It provides a direct relationship to battery power parameters. Battery conductance is measured by evaluating the voltage response to a small, select frequency AC current signal briefly impressed on the battery. The resultant conductance measurement provides pertinent battery information without the need of bringing the battery to full discharge.
