Diagnostic Battery Management
Battery diagnostics has been lagging. Performance transparency in batteries must be equal or higher than in fossil-burning fuel.
Cadex realizes the importance of batteries and is developing rapid-test technologies that assesses capacity noninvasively. Capacity is the leading health indicator.

Turning Battery Diagnostics into Household Names
In the last few years, multiple battery test methods have emerged, each with benefits and limitations. The Battery Diagnose Pyramid illustrates new and old technologies.
Patented Rapid Test Methods by Cadex
Dynamic Response
Dynamic Response has successfully been used in battery analyzers to rapid-test batteries, a method that checks ion-flow in Li-ion as a function of battery health.
U.S. Patent 10,302,709; U.S. Patent 7,622,929
Multi-Model Electrochemical Impedance Spectroscopy (EIS)
Spectro™ takes the electrochemical evidence of a battery and creates a Nyquist that is modeled against a matrix. Data fusion then calculates capacity and other values analogous to face recognition.
U.S. Patent 7,072,871; U.S. Patent 6,778,913
Parser Technology
The Parser estimates the capacity of Li-ion by measuring the residual charge with the Extended Kalman Filter and then counting coulombs to full charge. The sum of residual charge plus new charge equals available battery capacity.
Limitations: The battery must by sufficiently discharged (40%) to gain a long enough ‘runway.’
