About the lithium-ion battery analysis web service technology
Our lithium-ion battery analysis web service allows you to obtain analysis results on battery characteristics, degradation status, resistance increase factors, and more via an API. This is achieved by simply sending your lithium-ion battery charging data to Murata.
The charging curve analysis method employed in this web service is an evaluation technique that acquires information on the battery capacity, internal resistance, internal battery status, and other elements by analyzing the voltage changes (charging curve) obtained during battery charging. You can grasp the battery characteristics and degradation status quickly and accurately just by sending the charging data (logging data during charging) to Murata.
Furthermore, this web service combines this charging curve analysis method with Murata's many years of experience in battery materials and design. As a result, it enables utilization in a wider range of applications than ever before. It will also make it easier to develop various battery-data-driven applications and solutions.

Feature
Contributes to the development of highly reliable products through highly accurate battery analysis data and degradation safety assessments
Murata combines our unique knowledge with the charging curve analysis method that analyzes voltage changes (charging curve) in batteries during charging. This enables to obtain various information with high accuracy regarding the internal status of batteries and the degradation mechanisms, including reductions in the positive and negative electrode capacities, charging imbalances between the positive and negative electrodes.
Moreover, based on the above analysis results, we are currently developing a function to enable the evaluation of the safety of the battery degradation status. Realizing this will lead to the elimination of unsafe batteries. Therefore, we expect this service to contribute to the design and provision of highly reliable products and services.
We are developing a function to be able to grasp the safety of batteries by judging safe degradation and unsafe degradation.
Furthermore, we can also provide battery discharging simulations (discharging curve estimations for each discharging rate) based on the analysis results.
You can utilize this data in ways such as estimating the driving range and operating time of EVs and other vehicles.Please flick to see
It is also possible to conduct battery discharging simulations (discharging curve estimations for each discharging rate) by analyzing the charging data. -
Feature
Possible to introduce at low cost
When you send battery charging data to the server managed by Murata, we will analyze the charging data and send the results back to you.

FAQ
The data is acquired at the same time as the battery is charged. The analysis is then completed in a few seconds after the battery charging is complete.
Specialized battery knowledge is not required. Please feel free to contact us about the methods of introducing this service and utilizing the analysis results.
The main benefits of the charging curve analysis technique are considered to be the following:
- If you have chargers, charging/discharging devices, or other equipment, it is possible to obtain the data necessary for analysis. Therefore, there is no need to newly introduce expensive diagnostic equipment.
- Various types of information can be obtained in relation to the battery degradation mechanism. This makes it easier to manage batteries based on the degradation mechanism.
- This evaluation technique is based on the principles of batteries (chemical reaction of the positive and negative electrodes). Therefore, there is no need to build an inference model that uses large amounts of historical data. Moreover, it is possible to easily ensure the robustness of the analysis.
It is possible to determine whether the degradation is safe or unsafe. This is helpful in reducing fire risks, evaluating the potential for reuse, and planning safety measures.
