Thanks for the good questions that are relevant for this topic. If you need any more info, please feel free to contact us. 1. Does AC-IR measurement depend on the SOC of the lithium battery ? In general, the lower the SOC, the more significant is the influence on the measurement. Reproducibility would be significantly worse with a low SOC. Therefore, we recommend measuring at a higher SOC to achieve a more accurate AC-IR result. 2. Does AC-IR measurement depend on the temperature ? Yes, temperature changes could affect the measurement results. We would recommend keeping the ambient temperature in the measurement environment stable. In general, measurement results would be within the accuracy specifications of the instrument itself if measurements are executed within the stated temperature range of the instrument. 3. What is the model number (Hioki part number) of the single contact probe for the BT series battery testers shown in page 18 ? You can find a selection of HIOKI probes in our catalog (pages 22/23) that you can download from here: www.hioki.com/euro-en/download/37483 Please look out for example for L2100 or 9772 for your purposes.

@@hiokieurope Thank you very much. I hope this information will be helpful for those who work with batteries

Hello Isac, thank you for your question. The Model Number of the test fixture shown in the video is 9262. Hope that helps! Please contact us any time, if you any more requests. Kind regards, your HIOKI Europe Team

@@hiokieurope Thank you

@@isacdaimary9908 You're welcome!

Hello Athar's Chem, thank you for your question. Normally either one method can be used for impedance measurement of electrolytes. - Liquid-state: Use electrodes for liquid. - Solid-state: Fix in coin-shape, and then measure as coin-cell. We assume that the “FTO” is a conductive glass plate, and that you would like to use it as the electrodes. However, we are not in the position to talk about gel-state DUT measurement, because we do not have any leads/fixtures which are suitable to measure it. Possibly, our forthcoming item (in the near future), Slurry measurement system might be of your help. If you need further help, please let us know, where you work, so our local partner can contact you. Thank you!

Hi! Please send an email to hioki@hioki.eu and our engineers will be happy to help you

You're welcome!

Glad it was helpful! Kind regards, HIOKI Europe Team

Our pleasure! Kind regards, HIOKI Europe Team

Yes you can use the data logger in server rooms to measure for example temperature and humidity wired or wirelessly. Some other applications that are mainly automotive related, however can be used for other applications as well: 1) Measurement on Li-Io cells in vehicles. Beside logging the cell voltages, the temperature around the battery can be measured, too. Depending on the configuration of our data logger, up to 120 measuring points can be recorded at the same time in this application. 2) Measurement of strain on vehicles during operation. The sensors can be attached to the appropriate locations on the vehicle. Data can be sent and recorded wirelessly to the main device. 3) Temperature measurement in the vehicle. Here, up to 210 measuring points inside and outside the vehicle can be measured, depending on the configuration of the system. 4) Temperature measurement of the brakes of a vehicle. Similar to application example 3), temperatures can also be measured and recorded at up to 210 measuring points. We would be happy to sit down and talk further about your specific needs, just send an email to hioki@hioki.eu.

Glad you enjoyed it! Kind regards, HIOKI Europe Team
