Electrical Engineering and Mechanical Design

Mechanical design in the field of electrical engineering is the basis of our work. We will completely solve your requirement for the functional unit of a part or assembly - including firmware and software development. If required, we will also support these systems with applications.


Development of electronics

We will design a functional circuit diagram, and then a circuit board based on it. We will assemble, animate and deliver the functional unit. Depending on the order, we are able to deliver the final product including EMC measurements for compliance with EU standards.

Mechanical design

We will design a solution concept and create a 3D data model of the whole. According to the nature, we will perform simulations and necessary calculations. An integral part is the creation of drawings and technical documentation.

Firmware and software development

For more complex systems with microprocessors, we create firmware and software to ensure the complex functioning of the system (including, for example, FW updates via WiFi). We also support systems with client-server architecture applications.

Production, drawing and technical documentation

Documentation is an integral part of the individual systems and subsystems. Its role is indisputable and crucial in the case of system interfaces for further integration into higher design units. We create it for both structural and electronic units, including interface definitions.

Validation of the whole

We physically test the manufactured prototype according to the customer's requirements in our own accredited testing laboratory. You do not have to deal with the capacities of external testing laboratories.

What customers say...

Our cooperation with DEVINN on the hydrogen prototype of the Tatra special has begun.
The human, but at the same time professional approach of the entire team allows both parties to discover the specifics of each other's fields and thanks to this we are gradually expanding our joint activities.
The level of flexibility and expertise combined with effective and friendly communication makes DEVINN a partner with great potential for development and implementation.
Kamil Košt'ál, tatra trucks
We see DEVINN as an important partner for development activities in the field of electromobility. They have enough quality human resources - as a company, we don't have to worry about them not being able to cope with whatever today's trends in the automotive sector require.
DEVINN is not only our supplier but also our customer. We see it as an important customer for charging technology - AC and DC charging stations, which are manufactured by our company Olife Energy.

Watchdog traction battery monitoring system

Watchdog is a monitoring system for traction batteries that provides online information on battery status, i.e. undercharge, temperature, function. The use is especially in warehouses and production. In on-line mode, it reports any malfunction for intervention by specialist units. This prevents damage caused by battery burning or destruction by undercharging. The system monitors 24/7.

Bread Board

For our customer, we have developed a test condition that simulates the operation of all the electronic components of a car. The test stand consists of a frame and boxes for the components and wiring harnesses with connectors for connecting the components. Each unit is equipped with a measurement and communication module.

H2BASE mobile hydrogen energy generator

In 2020, we launched a unique device - an electricity and heat generator that uses hydrogen instead of fossil fuels. Thanks to hydrogen propulsion, it is a completely emission-free, clean technology, with only distilled water as waste. H2BASE finds its application as an alternative to diesel generators or for recharging electric vehicles.

Flexible access

First we listen, then we propose solutions. Whatever we do, we tailor it to the specific needs of the customer.

Comprehensive portfolio of services

Complex systems with HMI, integration into internet environment, knowledge of CAN. Binding of electrical schematics, 3D data, drawing and PI diagrams. These are all areas that we come into contact with regularly and offer to you.

From idea to prototype

Our strength is that we can take your project from the first sketch on paper to a working prototype. Sometimes we even go further and prepare projects for mass production.

Working with confidential data

We grew up in the automotive sector, where data security is a given. With certifications like TISAX, we guarantee that any sensitive data for your projects is 100% safe with us.


Your data is safe with us. We are certified according to TISAX specifications.

The quality of our work is proven by other quality certificates such as ISO 9001.

What do we work with?


Our hardware equipment includes a prototype workshop equipped for vehicle conversions, a fiber laser cutting machine, electrical measuring instruments, test benches and DEWESoft and ALMEMO data loggers.


Most of our work is done in software such as CATIA V5, ProEngineer/Creo, SolidWorks, LabView, Eagle, Visual Basic, Vector CANoe or vehicle diagnostics ODIS and VAS.

Accredited testing laboratory

The entire development process requires intensive testing of various stress situations. For us, this testing is easier thanks to our own accredited testing laboratory a few metres from the development site.
