Overview of developed products and technologies

This technology is a multiple impedance measurement method to establish a safety diagnosis suitable for lithium secondary batteries.

This multiple AC impedance method enables measurement of many characteristics simultaneously in a short time, and provides a visualization (3D) and database service for the results.

The same method (observation of changes in resistance and output voltage) as that used for lead-acid batteries is currently used for safety diagnosis of lithium secondary batteries used in electric vehicles and stationary storage batteries, but this is not sufficient for diagnosis due to differences in operating principles and battery materials. Our measurement method enables safety diagnosis suitable for lithium rechargeable batteries.

[Core technologies]
Advanced basic knowledge and experience with electrochemistry, and battery prototyping, evaluation, and analysis technologies

Experience, knowledge, and know-how related to effective evaluation technology for battery characteristics (AC impedance and DC pulse measurements)

Features and points

The state of health (SOH) and state of life (SOL) of each cell in a module can be analyzed and evaluated instantly and accurately with a pseudo-equivalent circuit.

This makes it possible to optimize battery operating conditions and create deterioration countermeasures for each application, thereby extending the service life of the batteries in use.

It has both measurement and diagnostic functions, as well as multiple functions for simultaneous measurement of the relevant characteristics of individual batteries that constitute a module battery and batteries that are integrated together.
