Digitalization of the battery controller configuration with individual Android app
HOPPECKE digitizes the configuration of its battery controllers with a custom-developed Android app, thereby increasing efficiency and process reliability.

HOPPECKE is known worldwide for its high-performance energy storage solutions and is the largest European manufacturer of privately owned industrial batteries. With the premium battery controller Trak Collect 2.0, the company is setting new standards: it is the first measurement, evaluation and communication unit for lead-acid batteries that displays the “State of Usage” and “State of Readiness” in real time.
Until now, commissioning the controller was a challenge: each controller had to be configured manually according to the order data stored in SAP - a process that was not only time-consuming, but also a potential source of errors.
Solution: A smart app as the key to efficiency
The aim was to develop a customized Android application that automates the configuration and thus intelligently combines SAP, Bluetooth communication and the Trak Collect 2.0. The app was individually tailored to the customer's requirements and the hardware used.
With the new solution, configuration data originating directly from SAP can be scanned as a QR code and transferred to the controller via Bluetooth - without any manual input.
Result: Sources of error eliminated - efficiency improved
The new app has created an end-to-end digital process that
- eliminates manual sources of error
- significantly speeds up commissioning
- and ensures full integration with SAP and the hardware without media disruptions.
How it works: intuitive, mobile, error-free
1. start the configuration process via the app - all available battery controllers in the vicinity are displayed (incl. name, hardware address, reception strength, current measured values) and are ready for connection. 2. visual feedback on the device - as an active Bluetooth connection is otherwise only indicated by a small, hard-to-read symbol on the controller, the app automatically changes the color of the controller's LED display every two seconds during the connection. This means that the correct controller can be identified at a glance. |  |
| 3. scan the QR code - the code generated by the SAP system contains all configuration data. |  |
| 4. check the data and write it to the controller - done. |  |
"The technical refinements and the exploitation of the digitization possibilities only impress the customer if the end result is coherent for the application. This is guaranteed by communication that is technically unambiguous but still clearly understandable for all “non-IT experts” involved. The awareness that the customer still finds it difficult to formulate the requirements for the degree of digitization and the corresponding interface description, especially for the production areas, made the difference when working with SIGMA. SIGMA masters this balancing act: making “programming language” sound understandable for everyone else. This eliminates tedious rework, unnecessary changes and lengthy discussions. Hoppecke has received an app that works reliably, is easy to use for all colleagues and has measurably improved work in production."
