ㆍMeasurement : DC AC Step Pulse Ramp

ㆍDC Canceling Technique for 10 μV Resolution of Voltage Measurement

ㆍLogic Circuitary for 10 μsec Simultaneous I-V Measurement

ㆍBattery’s transient response can be obtained by applying current step function to a battery and measuring

voltage response as a function of time and at wide ranges of time scale.

ㆍTime-varying internal resistance can be obtained by subtraction of initial voltage from measured voltage

response and then by dividing constant current value.

ㆍMetadata Compiler automatically extract characteristic parameters from TRA data including internal

resistance components.

ㆍFrequency response analysis is a set of measurements of complex impedance which can be obtained by

applying sinusoidal current and measuring voltage response as a function of frequency.

ㆍComplex impedance can be plotted as real & imaginary part (Nyquist Plot), and the real part of impedance

indicates frequency-dependent internal resistance of battery.

ㆍMetadata Compiler automatically extract characteristic parameters from FRA data including internal

resistance components.

ㆍSequence Builder is a software tool for user’s own battery test sequence programming.

ㆍSequence Builder is useful when multiple measurements are carried out during a full charge/discharge cycle

including TRA, FRA, OCV and internal resistance.

ㆍMetadata Complier is a software tool for automatic parameter extraction from battery measurement data

such as charge/discharge, TRA, FRA, OCV and cycling.

ㆍBattery metadata can be categorized as battery information, measurement conditions, extracted data and

characteristic parameters.

ㆍExtracted battery metadata can be handled as tagged data in data management software.
