Initial situation: why automate test benches?
What does test bench automation mean here?
Test bench automation replaces manual operation of climate chamber, source/sink, BMS and logging with reproducible sequences — shorter runtimes, less Excel work and audit-ready evidence for certification paths.
Problem
Each component had to be operated manually (climate chamber, source/sink, BMS, logging).
No restart after faults or power loss; test runs often started from scratch.
Heavy dependence on expensive single licenses of roughly EUR 28,000 per year.
Manual Excel-based reporting consumed around two extra hours per run.

FAQ on test bench automation
What is test bench automation for HV battery testing?
It replaces manual operation of climate chamber, source/sink, BMS and logging with reproducible sequences, restart logic, limit checks and auto-reporting — typically over CAN and related device interfaces.
How long does it take to automate test benches?
In this reference project the first prototype was ready after four weeks; full automation including on-site commissioning was productive after eight weeks.
What measurable results does bench automation deliver?
Test time per run from about 10 to 4 hours (−60%), reporting from roughly 2 hours to 3 minutes, consolidated licenses and audit-proof data storage for certification paths.
