ENG Systems, SANYO Develop Better Batteries with LabVIEW
Print
The ENG battery tester is compatible with a wide range of product offerings.
The Challenge
Developing a flexible battery test system capable of keeping pace with changing product requirements.
The Solution
Using NI LabVIEW to design a precise tester that is compatible with a wide range of product offerings.
SANYO Corporation has produced quality batteries for years. However, to keep pace with the evolution of battery technology, the company required advanced equipment for measuring and testing its products. We at ENG Systems helped SANYO meet this challenge by using LabVIEW software to design a new test system that would be compatible with most batteries up to 24 V.
We control the tester with a measurement program developed in LabVIEW and can modify or improve the program structure at any time for new testing. We store the parameters in an external database, so the shell program does not need to be modified when changing the process.
Using LabVIEW, we also created a front panel for the tester that is logical, easy to handle, and displays all necessary information. The front panel displays test results with a color-coded scheme. When the program detects a failed battery, the results appear in red, and the user is notified to separate the failed battery. The results are saved to log files, which users can process with Excel or text editor programs.
