Why EMC tests for electricalVespas are so important – prosimo at TÜV Nord

You think a Vespa-Conversion is just a bit of screwing and electronics? Far from it. So that our electrified Vespas not only drive reliably, but also do not disturb other devices – and are not disturbed themselves – we subject them strict EMC tests according to the UN/ECE R10 standard.

Why is this so important? Imagine someone with a pacemaker standing next to you while you Vespa start. Without tested electromagnetic compatibility, such devices could be affected. That’s why we test our kits in the EMC laboratory of TÜV NORD Hamburg.

We've already successfully tested our smallframe kit. And because we continuously improve our hardware and software, we repeat these tests regularly. These tests also bring us a big step closer to TÜV certification for our largeframe kit. Why not ask other providers if they can offer TÜV or EMC certification? At Prosimo, we're setting new standards – for your safety and everyone else's.

Vespa Electrical conversion with TÜV

Electric conversions are more than just a battery, throttle, and motor. They not only have to be safe to drive – they also have to fit seamlessly into their surroundings. That's why we were able to offer one of our converted Vespas at EMC test (electromagnetic compatibility) at TÜV Nord in Hamburg.

And yes – that was exciting. And important.

What does EMC actually mean?

EMC stands for electromagnetic compatibility . It sounds complicated at first, but it means something very essential:

A vehicle must not interfere with other devices – and must not be interfered with itself.

This applies, for example:

Pacemakers or other medical devices
Radio traffic (police, fire department, etc.)
Vehicle diagnostic devices or charging electronics

For us, this means specifically: Our kits must prove that they function reliably in the environment – without “radio chaos”.

The test at TÜV Nord

Our conversion was examined in a special EMC test chamber – under real conditions with the engine running, the control system activated and all relevant consumers connected.

Among others, the following were tested:

Radiation (how much electromagnetic energy is emitted by the vehicle?)
Immunity (how does the system react to external electromagnetic influences?)
Radio frequency behavior of the controller and battery unit
Wiring, connectors, shielding – everything was examined

What have we learned from this?

Our preliminary work in terms of clean cable routing , shielded signal cables and a well-coordinated system design has paid off.

The test showed:

✔️ Our electrified Vespa meets the requirements of UN/ECE-R10 standard
✔️ We are on the right track – and with an official test report

Why this is also important for you as a driver

With an EMC-compliant modification, you're on the safe side when it comes to approval. This is crucial not only for the TÜV inspection and registration, but also for your own peace of mind.

Because let's be honest: who wants to risk the scooter suddenly acting up because the cell phone is transmitting?
