112 Ideally, the tests and checks run automat- ically with processes and test results re- corded accordingly for the necessary proof and certification. This also requires suitable simulations and HV-compatible accesso- ries, such as special cables, breakout boxes and adaptations. For these applications in the high-voltage range, Softing Automotive designs and develops individual adapters, supply systems as well as measurement and simulation technology for safe handling in the laboratory, on the test bench and on the vehicle for voltages and currents of up to 1000V/1000A. Compliance with the highest safety standards for high-voltage accessories Measuring adapters and breakout boxes can be used to safely and reliably perform mea- surements on normally closed high-voltage systems. HV measuring adapters use origi- nal vehicle connectors and offer interfaces for tapping individual I/O signals as well as access options to high-voltage power sup- ply. HV breakout boxes additionally allow the manipulation of signal and supply lines with suitable jumpers or interruptions or by short-circuiting or connecting a leakage and contact resistance. HV test adapters allow the integration of HV ECUs, such as battery management systems, into HiL test systems with the touch-proof design of the components and the galvanic isolation of all taps to be measured or influ- enced from the high voltage, thus covering the highest safety standards. Passive cell simulations make it possible to dispense with real batteries or with complex and ex- pensive active cell simulations when devel- oping ECUs for battery monitoring because they simulate the complete cell stack in a bal- anced state of charge and the individual cell controllers always detect suitably charged cells and thus a fully functional battery sys- tem. This allows all functions of CSE ECUs to be tested without direct battery involvement in a cost-effective setup. High-voltage capacity decades replicate one of the most important energy storage IT and Automotive Caution: High Voltage! Greatest possible occupational safety in the high-voltage range thanks to highly reliable testing and verification systems By Armin Baumann, graduate engineer, Managing Director of Softing Automotive Nowadays, the development of vehicle components and their integration into the vehicle are hardly conceivable without high-voltage technology. The demands made on the electronic testing and verification systems used for this purpose are extremely high and diverse – particularly in the case of electric and hybrid vehicles. Here, safe measurement, testing, verification and application in the high-voltage range are just as important as knowing how to handle complex ECUs or use transparent and reproducible test procedures.
