Test methods range from taking a voltage reading, to measuring the internal resistance by a pulse or AC impedance method, to coulomb counting, and to taking a snapshot of the chemical battery with Electrochemical Impedance Spectroscopy (EIS).
To test a lithium-ion battery, most rapid-test methods excite the battery with pulses to observe ion-flow in the time domain. The results may not be as accurate as a charge/discharge/charge cycle test, but the battery can remain in service and testing times are significantly shorter.
Capacity Testing: Capacity is the amount of energy a battery can store and deliver. Learn how capacity testing measures the ability of a battery to hold a charge and provide power over time. Voltage Analysis: Voltage is a critical factor in determining a battery’s performance.
Battery testing is complex even for the sighted man but progress is being made. Better technologies will eventually immerge. Story of blind men trying to figure out an elephant through touch. The tale provides insight into the relativism and opaqueness of a subject matter, such as a battery.
No practical method exists to quantify all conditions of a battery in a short, comprehensive test. State-of-health (SoH) cannot be measured per se, it can only be estimated to various degrees of accuracy based on available symptoms. If the symptoms are vague or not present, a reliable measurement is not possible.
