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.

Quality is when your QMB goes “High-Five-S” with you

We know where quality must ultimately be demonstrated and proven: In the product, in the customer’s application. But where does quality begin? On the one hand in technical development and on the other hand in the organization of workplaces in production. Employees who keep their workstations tidy maintain an overview, have access to the right tools at all times and can work on the product efficiently and with quality assurance.

Information visit to TRAMAG by the VDI District Association of Bavaria North-East

On the afternoon of St Nicholas’ Day, the TRAMAG plant in Fürth hosted an information event for members of the Association of German Engineers (VDI) from the Bavarian North-East District Association. Due to the regional proximity and also taking TRAMAG’s 100th anniversary as an occasion, we received a request from the Nuremberg VDI local group to visit our plant, which we were very happy to fulfil.

“Quality is when the Customer comes back and not the Product”

The most technically innovative or economically attractive product in an application is worth nothing if the quality is not right. Not only would the failure of the product itself have to be lamented, but possibly also further damage to the entire application.
