SOH integration: place the battery certificate among your sales photos
One image among your sales photos, featuring a QR code to the full report
A measurement that no one sees, sells nothing
An SOH percentage disappears in the ad copy. It ends up somewhere at the bottom among the options, or it isn't included at all when transferred to a platform. The measurement has been taken, the certificate is ready, and the buyer scrolls right past it.
That is a shame, because with a used EV, the condition of the battery pack is precisely the one thing a buyer cannot see, cannot hear, and cannot test drive. It is exactly the information on which they should base their decision.
Why an SOH API alone is not enough
A link works fine, but it always runs from one system to another: from your inventory management to a single advertising platform. If you want coverage on all the places where your cars are listed, then you need a whole series of those links. And every time a platform or a field changes, someone has to tinker with it.
If you work with a single system and a single channel, it is quite manageable. If you operate with multiple branches and advertise on multiple platforms, then achieving one hundred percent coverage through integrations is a project that is never truly finished.
Een koppeling per systeem
Elke bestemming vraagt een eigen verbinding. Komt er een platform of een vestiging bij, dan moet er opnieuw iemand aan sleutelen.
Het certificaat in de fotoserie
Eén beeld tussen de foto’s. Waar de foto’s heen gaan, gaat het certificaat mee — zonder dat er iets gekoppeld hoeft te worden.
The certificate as an image in the photo series
Photos are the most important part of selling a car, and they go everywhere: every platform, every branch, every export. If you include the certificate among them, it automatically travels along without needing any integration.
RotoView Studios has recently become a solution partner of The Battery Experts. If you work with their photo studio, the battery certificate is now simply included in the series: one image among the photos, featuring a QR code to the full report. Universal and standardized, for all locations and all EVs.

What is in the certificate
A CARA-certified report containing the SOH percentage, cell balance, warranty status, charging history, and a benchmark against comparable cars. Ready within five minutes, including a ready-to-use JPEG that fits seamlessly alongside your 360-degree images.
You don't have to learn a new system for it
The measurement is integrated into the existing workflow. No extra portal to log into, no subscription, and no onboarding of a new software package. You simply activate it within a process you already go through for every incoming car.
The toolkit works on over ninety percent of all fully electric cars and plug-in hybrids. Support is handled through our office in Blaricum, ensuring short lines of communication and answers in Dutch.
Would you prefer an SOH app or your own integration?
If you do not take photos via RotoView, the direct route simply remains in place. With the SOH app, your own mechanic performs the measurement and the certificate is ready within a few minutes. Via the integration, you retrieve the percentage, the measurement date, the mileage, and a reference to the certificate in your own system.
In practice, most companies combine it all: the app for the measurement itself, the photo series for visibility to the buyer, and an integration with the system where their inventory is managed.
