The BMS kit provides an ideal basis for initial prototype constructions and small series. Together with the cell sensor circuit (, it maps all necessary battery management and safety functions. It represents a development basis for customized battery management systems on an industrial scale. Using the BMS tool chain, you can adapt the BMS precisely to your battery system.
Wiring topology, cell characteristics, temperature characteristics, discharge characteristics, limits and time characteristics of the safety functions and the interface to the vehicle can be adjusted within extensive ranges. The tool chain and the BMS together guarantee that the safety characteristics you specify are actually implemented. In addition to the key components of the BMS, we offer you a comprehensive selection of accessories right up to complete BMS kits. These include contactors, pre-charging modules, load resistances, filter assemblies and connector sets. The BMS facilitates the safe operation of lithium-ion batteries up to 800 V. It supports different ESS (Energy Storage System ) topologies - single-battery and multi-battery systems for larger plants and systems.



While we are proud of our products and solutions, it is through our customers’ applications that the power in the innovative technology is unleashed.  Whether fully networked, highly automated, or operating fully autonomously, an effective mobile machine represents first class interdisciplinary engineering. Robust and safe integration into the system architecture of the machine and its work processes, while remaining convenient and user friendly, is the main focus. With thanks to our customers, here we would like to present a small selection of example applications.



We support our customers as a partner for the digitization and automation of mobile machines and the related work processes. Our comprehensive and highly interoperable STW modular system of high quality sensing, control and software products ensures a problem free integration in the final application.


As experts in all aspects of functional safety, we offer services in high level automation in the field of mobile machines, including autonomous functions and driving. Our STW ecosystem includes a comprehensive partner network of system integrators and distributors to ensure an optimal solution for every application, worldwide.


We accompany our customers from the start whenever the E/E system in mobile machines is concerned. For this purpose, we develop solutions to support the entire machine lifecycle. We offer our competence, our services, our products and the associated tools in the individual phases in order to make an efficient and continuous contribution towards the success of the machine. 



The STW "ECO System" is characterized through the integration of systems and products which transcend the borders between solution areas. Our partners also supplement the STW product and services portfolio for the benefit of our customers. The open nature of the product portfolio permits easy integration of the products into third-party systems or the supplementation of our system through further products by third party providers.
