Qvest and TRAILAR are developing comprehensive IoT monitoring

TRAILAR, a subsidiary of DHL, has developed an innovative system for commercial vehicles. It generates solar energy and feeds it directly into the power grid of trucks or vans. This pioneering approach not only enables logistics companies to reduce their fuel consumption but also contributes to reducing environmental impact through lower emissions.

The key technology behind this award-winning system is the Cumulocity IoT platform from Software AG. The platform analyzes all relevant data in real-time and presents it graphically, providing user companies with a clear view of the achieved savings.

Depending on the application and usage, up to 5% of fuel can be saved, reducing CO2 emissions by about two tons per truck annually. As an official integration partner of Cumulocity IoT, it was Qvest's task to develop missing software modules to calculate the actual fuel savings of a vehicle.

Our Solution

The TRAILAR system is based on flexible solar mats with a thickness of only 3 millimeters. These mats are mounted on the structure of trucks, trailers, refrigerated vehicles, or vans. The solar cells on the roof generate electrical energy during daylight, even without direct sunlight, which is directed to a smart controller. This controller efficiently channels the harvested energy into the vehicle's battery, where it can be utilized for various applications like tail lifts, lighting, or refrigeration units. This reduces the load on the alternator and engine, thereby cutting fuel and maintenance costs.

To accurately calculate the actual fuel savings, we initially integrated the telematics unit and further developed the platform tailored to TRAILAR's requirements. For easy-to-understand monitoring and reporting, raw collected data is processed. First, the vehicle's telematics transmits all sensor values to the Cumulocity IoT platform. For processing, Apama serves as the live streaming analytics component, accompanied by Java microservices developed by us. These microservices extract the data, rectify sensor deviations, and calculate the actual consumption in kWh.

Lastly, we created three customer-specific widgets for the Cumulocity dashboard. These widgets ensure a tailored visualization for comprehensive monitoring. The end result is a detailed Cumulocity dashboard, providing complete transparency on fuel savings for TRAILAR and its clients. Depending on the use case, the solution promises a return on investment (ROI) within twelve to 18 months.

Sascha Mühlhausen | Head of Product, TRAILAR

In a highly professional and agile collaboration with Qvest Digital AG, we've developed an IoT platform based on Cumulocity. This platform employs dashboards, widgets, streaming analytic engines, and microservices to process, store, and visualize data—such as the solar-generated energy from the TRAILAR Smartcontroller System. This capability allows us to transparently demonstrate the added value of our product to our customers.

The Qvest Digital team stands out for its ability to swiftly initiate development in a highly flexible manner. Team members are dedicated in every phase, making the collaboration so enjoyable that we've even had some shared pizza or brewery evenings. It almost feels as if the team is an integral part of TRAILAR

Our Customer

TRAILAR was founded in 2017 by two DHL employees as part of the Incubator Program Start-up Lab within the Deutsche Post DHL Group. With its new fuel-saving technology, TRAILAR's innovative system offers a sustainable, efficient, and cost-effective solution based on lightweight, durable photovoltaic modules. Since 2018, TRAILAR has been an independent subsidiary of DHL.

Patrick Steinert | Head of Emerging Technologies, Qvest Digital

The development for TRAILAR allowed us to contribute to an equally exciting and innovative project and collaborate with an exceptional team. Among all participants, there was a significant level of trust, which formed the perfect foundation for our agile development approach. In addition to the excellent professional partnership, the communication was very pleasant and on a human level. Our teams merged, enabling us to achieve results in a remarkably short time, of which both companies could be proud.
