Electrical testing in the field of automotive

The modern form of locomotion – electromobility – requires new approaches in research and development but also in testing.

The requirement for quality, safety and reliability are nevertheless paramount.

And this is exactly where IMA Dresden’s expertise comes in with its testing services.

The comprehensive test spectrum ranges from individual tests to complete validation of electrical components for almost every vehicle type and comprehensive load units.

Our advantage: Complete design and product validation from a single source.

LV 124 / LV 214 / LV 123 / LV 148 / LV 215  – ACCREDITED TESTS

In the broad field of electromobility, the LV 124 and LV 214 standards are the most important ones to be met.  The topic of electromobility does not have to be limited exclusively to the automotive industry; the rail vehicle and aviation sectors are also increasingly moving toward alternative drive concepts.

LV 124 was compiled by representatives of leading automotive manufacturers such as Audi AG, BMW AG, Volkswagen AG, Porsche AG, etc. and describes various electrical tests and their requirements that can be performed in our laboratories.

Scope of testing according to LV 124

Tests in the field of electromobility

In accordance to your requirements we perform a large variety of electrical tests and environmental simulations in our labs. No matter whether for a standard test, a special solution or a combination of overlay of several test units. We are also your partner when it comes to tests of the current profiles, the lifetime or an environmental test superimposed with a mechanical test.
