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.



We are proud of our products and solutions, but they really reveal their true colors when used by our customers. Whether digitalized, automated or electrified – mobile machines repeatedly delight with new innovations, in particular in terms of their user-friendliness, reliability and ability to integrate into work processes. Thanks to our customers, we are delighted to present a small selection here.


Our objective is to support our customers in all aspects concerning the digitalization, automation and electrification of their mobile machines. We consider the entire machine lifecycle and develop our STW product and service portfolio in alignment with this lifecycle. The ECO system, an open and holistic approach, facilitates the cross-topic integration of STW solutions. Furthermore, our product approach facilitates functional expansion through partner offers and hybrid, integrated products based on our system module.


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.
