160 Vehicles per Week: How teilAuto Migrated Their Entire Fleet to New Telematics in Just Three Months
Table of Contents
Company Background
teilAuto has been a key driver of sustainable mobility in Central Germany since 1992. Today, the car sharing operator manages a fleet of over 2,200 vehicles, serving more than 100,000 users at nearly 1,000 stations across 30 cities. The company focuses on an eco-friendly fleet and strengthens a sustainable mobility mix by closely cooperating with local public transport providers, city administrations, and cycling initiatives.
Ecology and social responsibility shape their business policy. teilAuto has held the “Blue Angel” environmental seal since 1999 and became the region’s first common-good-certified enterprise in 2019. The fleet is increasingly being electrified, with every EV charging at its station using 100 percent green energy.
By changing its legal form to a cooperative, teilAuto involves its customers even more in the mobility transition.
Problem
The proven iBoxx telematics units inside the teilAuto vehicles were approaching the end of their lifecycle. INVERS had the next-generation successor ready with the CloudBoxx, bringing new capabilities and deep integration with the Platform Core. However, replacing telematics during ongoing operations is always a major challenge for car sharing operators.
Typically, hardware upgrades of this scale require external service partners to install the new telematics. This introduces additional coordination that can slow down the process and cause operational bottlenecks.
Usually, operators coordinate these processes using API keys. These cryptographic keys can be used to assign the telematics units to the respective vehicles. It’s important to ensure that the right installer has access to the right boxes. Often, teams still exchange this information through emails or spreadsheets.
teilAuto was looking for a solution that maximizes installation speed by minimizing this administrative effort.
Solution
As a long-term technology partner, INVERS supported this ambitious hardware upgrade right from the start. The CloudBoxx offers teilAuto excellent stability in real-world operations and seamless system integration. For the rapid transition, the Installation Jobs feature was particularly crucial.
This feature allows teilAuto to control the entire installation process centrally. They no longer need API keys, emails, or spreadsheets. Fleet managers create their jobs for installing a CloudBoxx directly in the system, and installers from the team can log into the SmartControl App with their own accounts. They receive temporary, strictly limited access to the respective vehicle.
The app guides the installation staff through the configuration and provides helpful instructions. A mandatory digital functional test of the telematics follows. The process can only be completed after this test. This consistent standardization ensures that every installed CloudBoxx works flawlessly right away, eliminating time-consuming hardware rework.
As soon as a job is finished, the installer loses access rights to the vehicle and can move on to the next assignment.
Our installers arrive at the vehicle, connect the CloudBoxx, and the rest almost takes care of itself. It’s like a plug-and-play system.

This approach offers several advantages for the installation process:
- Targeted access and control: Limited access ensures the right installer has access to the right boxes.
- Efficiency and precision: Guided workflows reduce error rates and operational costs.
- Reduced effort: The operations team spends less time on administrative routine tasks.
- Maximum transparency: Real-time updates in the dashboard keep everyone informed.
Implementation
The ambitious project to migrate the entire fleet to new telematics within a few months was successfully completed in early 2026. In February, the last of the 2,200 CloudBoxxes was installed for the current fleet. The key to success was the perfect integration of Installation Jobs with teilAuto’s structured installation process.
On average, we migrated over 160 vehicles per week during live operations.

Results
With the new telematics, teilAuto is taking a digital step forward. The new hardware provides better system integration and proves to be extremely stable in real-world use. Smartphone-based vehicle access, first introduced in 2015, is now the standard for customers.
We are happy to support teilAuto in this growth step with the CloudBoxx and our Installation Jobs feature.
