More high-tech, less room for error: Why quality management makes all the difference in e-mobility

When we look at vehicles such as the Ferrari Luce, it becomes clear that electromobility is not simply a matter of ‘swapping out the powertrain’, but a fundamentally new system architecture – which is precisely why quality and precise fit are becoming even more crucial. Where thermal management, high-voltage components and power electronics are closely interconnected, even the slightest deviation can have major consequences. For VIEROL, this means: supporting workshops reliably in this new reality requires not only a promise of quality, but a systematic commitment to ensuring it.

This is precisely where VIEROL’s quality management comes into play. The criteria are clear: reliability, durability, safety and robustness – particularly for components that are considered sensitive in electric and hybrid vehicles. From a quality management perspective, these primarily include cooling systems and thermal management (e.g. chillers and coolant pumps), high-voltage contactors, electric motor mounts, and power electronics components. In these areas, workshops do not get a second chance; they need components that work reliably from the outset.

The consequences of using substandard or poorly fitting parts become apparent very quickly in practice: in the case of bearings, even minimal deviations from OE specifications are often enough to drastically increase wear – in extreme cases, leading to rapid failure. In power electronics, substandard materials can alter electrical resistance, causing malfunctions or compromising entire systems.

The suspension is also subjected to greater demands in electric vehicles. The additional battery weight combined with instant torque places greater strain on the components – making quality essential to preventing consequential damage.

To ensure that workshops do not have to ‘diagnose’ precisely these risks as well, quality at VIEROL begins long before installation. Before production approval is granted, material quality and dimensional accuracy are checked. Samples are measured using an optical 3D coordinate measuring machine and compared with the digital model – with micrometre-level accuracy. In addition, electronic testing is carried out.
For particularly sensitive components such as chillers, CT scanning even allows us to look inside. This makes it possible to identify structures, valve seats and potential manufacturing defects before a product even reaches the market. In short: quality management ensures that ‘it’s right’ is not just a feeling, but the result of a transparent testing process.

Another key factor lies in the supply chain. E-mobility components in particular often combine multiple materials and suppliers within a single product. It is therefore important to carry out thorough supplier audits and to consistently monitor supplier quality – ensuring that quality is not left to chance, but remains consistent.

And if issues do arise in the field, a structured complaints management process comes into effect: in case of doubt, products are immediately withdrawn from sale, analysed and – if necessary – assessed in direct consultation with the workshop. This feedback is not merely after-sales service, but a key part of our continuous product improvement process.
For workshops, the message is clear: particularly in the field of electromobility, tried-and-tested solutions, high-quality materials and conscious quality decisions pay off – rather than simply opting for the lowest price. E/E components are safety-critical. Work must be carried out strictly in accordance with the manufacturer’s specifications, including leak tests on the high-voltage battery and a proper insulation test once all work has been completed. Faults at this stage can cause the high-voltage circuit to shut down, lead to further damage or, in the worst case, pose a safety risk.

Or, as Lukas Greiner puts it:

“As electromobility evolves, technological complexity is increasing. To ensure safety, sustainability and reliability, consistent quality management is the key factor in turning innovations into market-ready, safe products.”

A look behind the scenes of quality management

Every spare part undergoes a rigorous testing process. In our video, we take a look behind the scenes at our quality assurance processes and show how we ensure the highest standards in the independent aftermarket.

Industrial CT/X-ray system for quality management

An industrial CT/X-ray system is used in development and quality management for non-destructive inspection of internal component structures. It reveals internal structures – such as pores, cracks, inclusions or assembly defects – whilst also enabling 3D measurement and target-actual comparisons directly based on the CT data set.

The system captures high-resolution images down to the micrometre level whilst enabling rapid scanning, allowing both component quality and process stability to be monitored efficiently.

Particularly in electromobility – for example, in sensitive components in thermal management or power electronics – such a CT system helps to identify potential weaknesses at an early stage, thereby reducing rework, returns and diagnostic costs.
