The rise of SOH measurements

The electrification of the automotive sector continues to accelerate and with it, the need for transparent and reliable information about the health of EV batteries is also growing. One of the most important parameters in this regard is the SOH value, full State of Health. In this blog, we explain exactly what SOH means, why Autel excels at battery diagnostics, and how Caralyzr supports garages by making this test easier and more accessible. In addition, we look ahead to 2027, when SOH will appear mandatory on Car Pass, thus providing garages with a new business opportunity.

What is SOH and why is it so important for EVs?

SOH indicates the condition of an EV battery compared to its original capacity at delivery. A battery naturally loses some capacity through use, temperature and charging habits. How quickly this happens varies greatly by vehicle and driver.

Correct SOH measurement is therefore essential for:

• Proper valuation of used EVs

• Transparency for customers in buying and selling

• Understanding actual battery health

• Better advice from garages and dealers

Reliable data is crucial in this process. And that's where Autel stands out.

Why Autel delivers one of the best SOH measurements on the market

Autel is known for its strong EV diagnostics, but the accuracy and reliability of the SOH measurement stands out in particular. There are three main reasons for this:

1. Deep battery analysis

Autel reads out much more than just basic capacity. Cell balancing, charge cycles and temperature data are analyzed, among other things. The more information, the more reliable the results.

2. Strong algorithms

Autel's software combines live data with technical reference values. This captures deviations and accurately displays the true battery condition.

3. Support for many EV models

Many tools only work for a limited number of vehicles. Autel, on the other hand, has very broad coverage, making it ideal for universal garages and dealers.

The result is consistent and clear SOH value that clients and professionals can rely on.

From 2027 mandatory on Car Pass: a strong opportunity for garages

In Belgium, from 2027, the SOH value will be compulsorily included on the Car Pass of every electric car. This provides a huge step toward transparency and trust in the used car market.

For garages and dealers, this means:

• A new service that you can actively offer with the right device and license.

• Additional potential workshop visits for customers requiring an SOH report

• Better and fairer valuation of EVs in buying and selling

• Expert status if you start correct SOH diagnosis now

So it becomes not only a legal obligation, but also an important opportunity to generate new sales and customer relationships.

Caralyzr clarifies SOH test for garages

The test becomes available in Caralyzr, where the often complex battery data is converted into a clear and understandable reporting.

Thanks to Caralyzr, any garage:

• Reading the results of an SOH test easily and visually

• See at a glance exactly what is going on with the battery

• Providing customers with clear and professional explanations without technical confusion

Caralyzr thus acts as the interpretation layer on top of the Autel test. The raw data is made clear so that any garage can quickly understand what the battery test shows and communicate this to the customer in a transparent way. This makes battery diagnostics accessible to everyone, without requiring in-depth EV knowledge.

Conclusion: to prepare now is to take profits in the future

The advent of mandatory SOH information on the Car Pass will change the EV market forever. Garages that invest in good diagnostics, reliable equipment like Autel and an efficient platform like Caralyzr today will have a clear lead from 2027. The demand for transparency and battery health is growing rapidly, and it is clear that companies that step into this evolution now will be the winners tomorrow.
