Esoro - Innovation und Technik
In March 2025, JKS Engineering AG strengthened its team with members from the former ESORO AG. This allowed the company to further diversify its innovation and engineering capabilities.
ESORO AG was and is known for developing and implementing successful projects. Its specialties include alternative drive systems such as hydrogen-powered trucks, the electrification of the world's first electric dumper truck, which has been in use for several years, and yachts in the nautical sector, among others. Not to be forgotten in this list are countless projects in many areas, such as medical rehabilitation, special equipment, and many highly specialized concept vehicles.
Following the insolvency of a customer, ESORO AG was also forced to cease operations. We are delighted to welcome the ESORO team and their customers to the JKS Group!
Battery technology: Development and production
The world is becoming electrified – modern high-voltage battery systems are the foundation for this. With the integration of the experienced engineering team from the former ESORO AG, JKS now has more than 30 years of expertise in the development of battery systems for cars, trucks, yachts, construction machinery, SKWS, and other applications.
Our expertise covers the entire value chain: from cell evaluation, packaging, cooling, system design, and BMS development for OEMs to the manufacture of complete and tested battery systems for small-series applications. We also have extensive experience in OTA monitoring and maintenance of such systems.
We support our customers in the specification, development, operation, and maintenance of safe and powerful battery systems—tailored to each individual application.
- Development of battery systems in the automotive, truck, and nautical sectors (topology, structure, current path, cooling, BMS)
- Prototype implementation of (sub)systems
- Safety analyses
Nautical
A reliable energy supply is needed to ensure the comfort and safety of modern sailing yachts. In the past, the engineering team has developed, realized, and implemented numerous customized battery and high-voltage systems for sailing yachts and tourist ships.
Among other things, these solutions enable emission-free operation of the hotel grid during the night, high energy savings and, depending on the design, a significant reduction in the weight of the system. The portfolio also includes steer-by-wire and force feedback for maximum control and design freedom.
With this expertise, we now offer state-of-the-art, safe, and efficient solutions for customers in the maritime sector.
- Design and implementation of high-voltage battery systems (customized or from standard batteries)
- High- and low-voltage systems
- Hotel grid solutions (SilentNight)
- Electrification of main and auxiliary drives
- Steer-by-wire and force feedback
- Electro-hydraulic systems
- Troubleshooting and over-the-air maintenance
Hydrogen and fuel cell technology
Hydrogen and fuel cell technologies make an important contribution to sustainable energy supply. Application-specific system integration is crucial for successful deployment.
We support our customers from conception and implementation to operation and maintenance of efficient, safe, and reliable fuel cell systems.
Mobility
Sustainable mobility is where our new engineering team's roots lie. For decades, the specialists now working at JKS have been developing, implementing, and testing alternative vehicle concepts and drive systems.
The portfolio includes electric racing cars, electric cars suitable for everyday use, a fuel-efficient gasoline vehicle, the TwinTrak hybrid system, numerous electric drive projects for OEMs, fuel cell solutions for trucks, and various show cars for automotive trade fairs.
We now bring this valuable expertise to bear in vehicle development for our customers – complemented by the existing competencies of the entire JKS Group.
- Hydrogen and fuel cell technology
- Electrification of vehicles, gravity trucks, etc.
- Engineering in the drive sector, especially for electric vehicles
- Unsinkable tracked vehicles
- Concept vehicles and technology carriers
Innovative medical technology despite increasing challenges
Medical technology is under increasing pressure: cost efficiency, high safety requirements, and stricter regulatory frameworks demand new, innovative approaches.
With over 20 years of experience in developing products for the rehabilitation and medical technology sectors, our team at JKS now supports customers in implementing safe and future-oriented solutions.
Thanks to our background in the automotive and other high-tech industries, we bring a wide range of technologies and processes to the table to develop high-quality, cost-effective, and standards-compliant products for medical technology.
Component development – 1 to 800’000
Our specialists optimize component properties throughout the entire development process – from the concept phase to the finished product. The focus is on the use of modern materials such as fiber-reinforced plastics (thermosets and thermoplastics).
Using sophisticated software tools for component, process, and material modeling, we ensure efficient, precise, and reliable design – for quantities ranging from one-offs to large series.
