E-MOBILITY
At INGUN, we use high-performance test equipment to ensure the functionality of the vehicle's electri-cal system.
This is ensured by properties such as quality, precision, durability (mechanical and electrical), consist-ently low electrical resistance as well as current carrying capacity. In addition, due to the trend towards miniaturisation, the accuracy of small test points plays a major role in increasing the first pass yield, i.e., testing as efficiently as possible.
All electrical and electronic components and systems in the vehicle - including the connectivity required for operation - should function for the entire service life of the vehicle if possible. When testing these components, high standards are therefore applied and various types of tests are carried out: e.g., function tests, in-circuit tests, cable tests and stress tests such as the burn-in test. In addition, leakage tests are used in the engine area, for example to test watertight plug connections.
Types of tests for automotive applications
- Functional test (FCT): In this test, the overall electrical behaviour of an assembly is tested by simulating the intended operating environment. FCTs can be performed in many different ways and with varying degrees of detail.
- In-circuit test (ICT): The ICT tests and measures all individual components on a printed circuit board and makes it possible to detect and eliminate defective components. Depending on the assembly, a high degree of automation can be achieved.
- Cable testing: Specialised tests and test probes are used to test cable harnesses and their use with connectors, e.g., detection test, connection test, position test and push-back test. You can find everything at a glance on our new poster!
- Burn-in test: This is an endurance test in which several assemblies are often tested simultaneously. By varying parameters such as temperature and voltage, an ageing process is simulated in order to find weak points.
Battery testing as a field of development
As the electromobility sector has grown, battery testing and the activation of battery cells have be-come increasingly important in these applications. The challenge here is to contact and measure each individual cell consistently and reliably. Depending on the battery type, different solutions are used, from the innovative four-pole measuring method with the VKB-635 clamps, dipole probes such as DPS-465 M, DPS-215 M and DPS-445, and well-established high current probes such as HSS-118 M, HSS-120 M and HSS-150 M with suitable tip styles.
Connector testing is indispensable
Connector testing is also central to automotive applications: In every vehicle, a multitude of different connectors ensures the transmission of signals, data, and energy. With our broad portfolio of specialised radio frequency test probes, we optimally cover the wide range of connectors, miniature switches, and connectors - both analogue and digital - using ideally-suited solutions such as the HFS-807 for HFM or the HFS-802 for H-MTD and MATEnet.
