TRAMAG Competences for the Electromobility (EV)

Load Chokes for Inverter Test Benches in the e-Automotive Industry

A large number of electromechanical components are installed in an electric car (EV). Their prototype development in the laboratory, but also their series installation along the production line, places new and extended demands on test technology and test systems. These components are, among other things, elementary components of the power supply but also of the drive train and must therefore be subjected to extensive quality tests with regard to functionality, load capacity and lifetime.

So-called inverters, bi-directionally changing from AC to DC to AC voltage, from the field of power electronics, are an essential link between the power supply and the drive train of the EV. The inverter converts the DC voltage of the accumulator batteries into a 3-phase AC current to drive the electric motor and, conversely, it also converts the excess AC braking energy of the electric motor into a DC voltage for feeding back into the accumulator batteries.

The core task in the functional test of the inverter is to simulate the system components of the energy supply, i.e. primarily the rechargeable battery, and the consumer, i.e. the electric motor, as a load and to make this load available for the functional test of the inverter. In these automatically operated inverter test benches, load reactors from TRAMAG take on the task of a substitute motor load and thus help to ensure that the tested electric cars, and thus electromobility, gets rolling reliably.

For years, customers all over the world have trusted in TRAMAG’s solution competence for the use of transformers, chokes and filters for the most diverse electromechanical applications, including TRAMAG load chokes for the safe and reliable operation of test facilities for the testing of inverters in the electric car industry.

Participation in the B2Run event on 25. July 2023 in Nuremberg

The weather was kind to the 14,000 runners, who were in the best of moods: Right at the start of this year’s B2Run event around Nuremberg’s Max Morlock Stadium, the rain took a long break. With a pleasant 22º C and a light breeze, a few rays of sunshine even fell on the colorful starting field of employees from many, many companies based in the Franconian region.

From the Fürth Solar Hill to the own Solar Roof

Eight years after saving the commissioning of the “Fürth Solarberg” with TRAMAG transformers, the Ammon family decided to install their own photovoltaic (PV) system on the roof of TRAMAG’s own company building. The 184kW peak output is sufficient to supply around 55 households with electricity, as reported in December 2011 by the Fürther Nachrichten on the occasion of the commissioning of the TRAMAG PV system, which was also attended by the Mayor of Fürth, who also climbed onto TRAMAG’s roof.
