Batteries Must Be Tested With High Accuracy To Ensure Their Proper Operation, especially because are Widely Used in our Daily Life.
The demand of Lithium-Ion Batteries increased from 2013 to 2023, as batteries are widely utilized in transportation, aerospace, defense industries, commercial industries, and also in addition in portable electronics devices.
This growing dependency on batteries, requires advancements in diagnostics, need to determine anomalies to prevent failures, to observe capacity loss in order to keep up reliability. Once the battery fades to set a capacity threshold, start to predict the end of the battery life span. In order for the electronic devices to operate as long as possible before running out of battery power, battery manufacturing companies put a lot of effort into maximizing the batteries’ life and performance.

Batteries can be dangerous as a result of the fact that they’ll store high amounts of energy and might explode, potentially causing serious accidents or injuries. However, we all have a tendency to use them daily, as an example, Lithium-Ion Batteries are used in energy storage applications like portable chargers.
Therefore, batteries must be tested with high accuracy to ensure their proper operation, well-developed battery testing should recognize all battery conditions and provide reliable results, even if the charge is low. This is a demanding request as a decent battery that’s solely part charged behaves in a similar way to a faded pack that’s fully charged.

At ETS Solutions Asia, we provide ETS Shaker Series with IPA Power Amplifier Technology which is designed to meet the requirement of Battery Testing and Shock Test Standards. The Vibration Controller software has also been developed to ensure the testing accuracy.
Battery Testing approach vary from taking a voltage examination to measure the internal resistance by a pulse or AC impedance technique to coulomb counting and taking a photo (snap shot) of the chemical battery with Electrochemical Impedance Spectroscopy (EIS). Capacity estimations by deciphering the chemical battery are a lot more complicated than digital monitoring by coulomb counting. Digging into the chemical battery involves proprietary algorithms and matrices that perform as lookup tables the same as letter of face recognition.
Reliable results are only potential once robust symptoms are present, but this is not often possible, particularly with unformatted lead acid batteries or packs that had been in storage. A decent battery force generally provides solid symptoms, but if are vague or not present, in that case means the battery has changed into a potato. This fools the system and therefore the battery becomes an outlier. Well-developed rapid test methods should properly predict nine out of ten. EIS has the potential to advance more and surpass other technologies.
