A Germany-based technology leader develops and produces an impressive range of innovative, modular high-performance battery systems for electric and hybrid utility vehicles. International vehicle manufacturers count on these reliable and scalable batteries.
Thanks to robust and compact Stäubli CombiTac connectors including custom pre-assembled cables, the innovative battery developper can guarantee safe, longlasting operation for its customers’ electric vehicles. What was once a group of German technology students researching and developing solar energy is now an international market leader in the field of modular, high-performance lithium-ion battery systems for utility vehicles. These innovative battery systems are used in electric and hybrid utility vehicles for passenger and freight transportation on roads, railways and waterways, as well as in industry. Some of the world’s leading utility vehicle manufacturers integrate these cutting-edge battery systems in their design concepts.
This modular and flexible product portfolio stands out for its very high energy density and exceptional thermal management, allowing for compact and freely scalable design. Developing a high-performance, modular OEM battery system called for a highly powerful, robust and reliable pluggable connection solution that was also extremely safe and had the necessary certification for use in the automotive industry.
Stäubli worked jointly with the battery technology leader’s engineers to configure a solution based on the modular Stäubli CombiTac system, flexible enough to support a 30% increase in the battery design’s performance even without any design modifications. Stäubli also implemented the connection with preassembled cables according to the specifications of the customer’s OEM clientele.
These connections, which carry current as well as data signals between the individual battery modules and to the power electronics, allow for safe battery maintenance operations. Simply unplugging the power module from the battery enables technicians to work safely with no live voltage. Therefore, it’s possible to change fuses without the need for an electrician or additional safety staff. This solution ensures that there is absolutely no voltage at the power module.
