Engineering

Working closely with the customer, our engineers take responsibility for the entire process, from concept and design to the finished solution.
We have extensive experience in developing customized systems in both the battery and electronics segments, and have delivered solutions to a range of industries with different technical and regulatory requirements. Each project is assessed individually to ensure the right technology, performance, and service life.
Engineering with a focus on quality and application
Our engineers work with:
- electrical and mechanical design
- selection of components and technology
- adjustment of voltage, capacity, power, and interface
- Encapsulation and protection for demanding environments
The solutions are developed with regard to operating conditions, performance requirements, and reliability, whether for industrial applications, medical equipment, or other critical systems.
Adapted to demanding requirements and environments
Freber develops customized solutions:
- challenging weather and environmental conditions
- medical and regulatory equipment requirements
- applications with high demands on operational reliability and precision
- long service life and stable performance over time
Through collaboration with a broad network of technology partners and manufacturers, we can combine our own engineering expertise with the right technology for each project.
From idea to finished solution
Whether the customer comes with a complete specification or just a need, Freber contributes with:
- technical advice
- design and engineering
- prototyping and customization
- Choosing the right production and delivery model
The result is solutions that are tailored to purpose, environment, and requirements, and that work in practice – over time.
Production
In-house production and technical expertise
We have our own production facilities with modern equipment and specially adapted tools that enable us to develop and manufacture both customized battery solutions and advanced electronics.
With solid technical expertise and control over the entire process, from design and prototyping to the finished product, we deliver solutions in battery systems, electronics, and panel production tailored to customer needs.
We develop and manufacture customized battery packs and battery systems tailored to the customer's specific needs. With our own production facilities, the right tools, and solid technical expertise, we handle the entire process, from cell selection and design to assembly, testing, and documentation.
The solutions are tailored to technical requirements, area of use, and environment, whether in the maritime sector, industry, or other demanding applications. Production can be scaled from prototypes and small series to larger volumes as needed.
Battery production

Cable production
Freber supplies tailor-made cable sets and wiring harnesses manufactured to customer specifications. We handle cutting, stripping, crimping, marking, and assembly with high precision and quality assurance at every stage.
With flexible production, we can adapt to both small and large series, ensuring that each cable is delivered fully tested and ready for integration into the system.


Panel production
We manufacture customized panels and control solutions, including the assembly of components, switches, instruments, and electronics. Our solutions are developed in close collaboration with the customer to ensure optimal functionality, user-friendliness, and operational reliability.
From simple panel mounting to more complex control solutions, we deliver finished products ready for installation.
