The Solution
Key Aspects of the Solution
- A PLZ-5WZ with impedance measurement capability reduced inspection time and cost.
- Capability of measuring discharge characteristics and impedance at the same time brings high reproducible test results.
One unit of PLZ-5WZ realized simple impedance measurement.
Mr. B contacted with a Japanese manufacturer of power supplies and test instruments, Kikusui Electronics Corp., which his colleague introduced to him. Based on current issue that he had been facing, impedance measurement system PLZ-5WZ Series was what Kikusui sales recommended him.
With the PLZ-5WZ, the impedance measurements are made during discharge, allowing for real-time measurement of impedance values from the DUT. This recommendation urged him to evaluate the unit. Kikusui offered Mr. B a demonstration model on loan.
Mr. B and his company evaluated the PLZ-5WZ Series and confirmed its performance.
When used on a trial basis, the PLZ-5WZ Series successfully performed the required test.
The PLZ-5WZ simplifies the process of collecting impedance characteristics test data.
Setting measuring conditions in the application software such as current and frequency starts impedance measurement.
The measured test results and graphical information can be copied directly from the application software to programs like Excel. Not only Mr. B but also engineers at the company realized that these ease of use enhanced the test efficiency.
Simultaneous measurement of the discharge characteristics and impedance can be carried out. This realized data precision enhancement and workload reduction.
Consequently, the company decided to introduce the PLZ-5WZ Series.
The PLZ-5WZ Series adds an impedance measurement function based on an AC system to the multifunctional electronic load PLZ-5W Series. The user friendly operation and high functionality such as arbitrary I-V characteristics (ARB) mode remains. Discharge characteristics and impedance can be measured at the same time. Current value for measurement can be changed based on battery capacity. This realizes highly reproducible measurement. This improved the deviations in the measured value. Moreover, it reduced the number of measurement and the inspection time.
Mr. B has got valuable suggestions from the Kikusui about the battery impedance measurement while he consult with them.
“The company O are planning to introduce the PLZ-5WZ Series at other factories”, said Mr. B.
