The Battery Manager Software allows to connect more than one PLT station to one supervising PC. Test data can be transferred to any central database server to backup and achieve data via TCP/IP.
The Remote Box for free selectable installation at the production line allows to start or stop a stored program.
The Production Line Tester (PLT) is typically installed at the end of battery production lines (finishing). An electrical load test after formation charging is essential to assure performance and quality. The energy discharged during this test must be minimized to eliminate the need for recharging after testing.
The PLT is the result of these concepts and quality requirements. Immediately after formation (generally after washing), the battery is discharged at a high current for a few seconds.
The HRD voltage at the end of the test is determined and compared to nominal values resulting in a pass/fail decision. The gradient of the discharge voltage is determined and compared to nominal values resulting in a pass/fail decision.
The PLT can be used for all types of batteries.
