Test engineering for e-mobility – a success story


Nowadays, e-mobility is the name of the game. It is now more important than ever before for vehicle manufacturers and the supplier industry to serve this market.

Complex ECUs, which are subjected to comprehensive and reproducible test scenarios, are required to ensure the smooth operation of the high-voltage batteries used. For this purpose, reliable test units and simulations of the real batteries and of the corresponding ECU environments are required.

The high voltage means manufacturers face difficulties during testing as this voltage necessitates safety measures that were previously not required.
In this difficult market, Softing Messen & Testen GmbH in the southern German town of Reutlingen has developed several test racks on behalf of customers which not only corresponded to customer requirements but exceeded expectations, an outcome customers were naturally more than pleased with.

It may sound simple but enabling and disabling the performance (something which at times can be quite problematic with high-voltage and high-current applications), the test integration of the ECU for the cell controllers and incorporating a high-voltage simulation into a compact rack in a user-friendly and safe manner, is in no way a trivial task. But the realization of these points was not enough for the Softing specialists from Reutlingen. They gave customers a pleasant surprise as all the systems they delivered came with an excellent price/performance ratio and special solutions they had not expected. A few examples: ingenious cable routing, internal wiring and the safe-to-use, durable drawers.

Totally satisfied with the Softing solution, the customer also commissioned a high-voltage terminal box for the cell controller.
