Inverter testing EOL

THE MODULAR SYSTEM OF THE FUTURE

Inverter testing EOL

Inverter – a device that plays an important role, especially in electromobility: The conversion of DC voltage into 3-phase AC voltage in order to control the speed and torque of electric motors.

In order to check the proper functionality before further assembly, we have developed an efficient solution together with our partner AVL SET. We can already look back on successfully implemented projects in automotive engineering.

Overview function test inverter

The basic task of the function test is to imitate an electric vehicle in order to be able to test the inverter under conditions that are as real as possible. This includes the DC source (battery) as well as the emulated motor windings. Thanks to our CUBES, a CE-compliant, safety-related enclosure without conventional protective fencing is guaranteed.

autfactory AMIT

In combination with our autfactory AMIT (Automated Modular Inverter Testing) software, you also benefit from a central control of the complete test bench. Each measurement result is recorded in the database and can be easily accessed in the form of a report. The transparent visualization of all test bench parameters helps you to keep an eye on your production and to make future-oriented decisions.

Your benefits

Increase energy efficiency

Thanks to the sophisticated energy recovery system, the operating costs of the test bench (total cost of ownership) are optimized.

Reliable partner

Trust the experts. We can look back on 20 years of experience with complex assembly lines and test benches in the automotive sector.

Increase flexibility

Our test bench control system autfactory allows you to create your own test sequences without any programming knowledge.

Inverter test bench (EOL) with transfer system

A possible implementation of your inverter test bench could look like this:

  1. Dielectric strength and insulation resistance test
  2. Inverter function test
  3. Laser marking for component identification

In this project, the component transport was implemented via a transfer system. The entire test stand can also be set up as a robotic cell instead. Individual stations, such as the function test, can also be duplicated to cover a higher production volume.

The complete implementation is provided from a single source: mechanical design, mechanical construction, risk analysis, electrical planning, control cabinet construction, electrical installation, plc programming, shopfloor software and hardware. Are you interested? Let’s talk!
