Development meets integration

System integration and co-engineering for complex drive and battery systems.

A drive system is more than the sum of its components. Mechanical, electrical, and thermal systems must work together—both technically and in series production.

At Handtmann, development doesn’t happen in isolation, but collaboratively. Co-engineering means shared responsibility from the initial requirements all the way to a fully functional system – involving additional partners as needed. It’s not always co-engineering – but it’s always a close exchange with the customer regarding how the component fits into the larger vehicle, module, or production system.

What We Do – Together and in an Integrated Way.

Development as a Partnership.

Co-engineering means developing together, not just supplying components. As a team – whether at the partner’s site or at ours. Understanding requirements, contributing our own development expertise, and coordinating with other partners as needed. Shared responsibility, a common goal.

Mechanical, electrical, and thermal systems—all in one.

System integration means more than just supplying a single component; it means understanding how that component interacts within the larger vehicle, module, or production system. Mechanical, electrical, and thermal systems come together to form a comprehensive system that is technically sound and truly functions in mass production – no isolated solutions, no interface problems.

What Sets Us Apart in System Integration.

01 · From concept to production.

Many development partners provide concepts. We deliver systems that stand the test of mass production. 164 MWh of battery capacity in mass production proves it: What we integrate is designed for manufacturing from the very beginning – there’s no disconnect between development, validation, and industrialization.

02 · All disciplines under one roof.

Mechanical, electrical, thermal, and software engineering – our developers work across disciplines under one roof. Integration doesn’t begin at the end; rather, it’s part of the development process from the very start.

03 · Partner, not contractor.

Co-engineering isn't just a buzzword. We share responsibility for development, take on specific tasks or the entire system, and coordinate with other suppliers as needed – to whatever extent the project requires.

Questions from project partners.

What distinguishes co-engineering from traditional contract development?

In co-engineering, we share responsibility for development – rather than simply following a specification. We achieve success together: Everyone contributes their skills and expertise to ensure the project’s success.

Can additional partners and suppliers be brought on board?

Yes – if necessary, we coordinate additional development and delivery partners and integrate their contributions into the overall system. We can handle the coordination ourselves – or it can be shared among partners if multiple parties are working on the system on an equal footing.

Does system integration end with the prototype?

No. An integrated system must also function in series production. We approach system integration and industrialization as a unified process – so that what works well in the prototype also operates reliably in large-scale production.
