RD Blatná – Research & Development for custom electronics and test systems.
R&D Blatná is the development team of TESLA BLATNÁ, a.s., focused on custom electronics, embedded software and test systems. We develop solutions for battery systems, electric motors and industrial applications – from design and prototyping through DFM, EMC and EOL testing to series EMS manufacturing in the Czech Republic.
Upon payment for the development work, the customer receives all agreed rights to the developed hardware and firmware.
We provide complete project data (ODB++ data, BOM with alternatives and test scripts).
We optimise projects for series production in the Czech Republic. To ensure quality, we also design EOL testers for automated final product inspection.
Technical data is processed exclusively within the EU, and we can enter into a mutual NDA upon request.
From Schematic to Series Production Under One Roof
We design with manufacturability in mind from the start. Every hardware project is developed with immediate consideration for DFM and cost optimisation. In addition to standard SMT lines, we operate a cleanroom for manufacturing sensors in a controlled ESD environment.
ECAD & Topology Analysis
PCB design in Altium. We perform functional analyses, signal-integrity simulations and re-engineering to optimise component selection.
Robust Embedded Software
Low-level firmware development (C/C++) for BMS, Li-Ion chargers and motor control. We implement CAN bus, LIN and MODBUS communications with an emphasis on cybersecurity.
EMC Pre-compliance Testing
We provide preliminary electromagnetic compatibility measurements in our partners’ certified laboratories. Potential EMI issues are identified during development, saving time and certification costs.
Handover & Production Transfer
Preparation of complete manufacturing documentation, placement data and verified templates. Smooth transfer to our automated SMT lines in Blatná or to a production site anywhere in the world.

Development Directly Linked to Manufacturing
Our development team uses the technological and manufacturing facilities of TESLA BLATNÁ, a.s. for prototyping, testing and transfer of projects into series production.
Custom Electronics & Drives
Design, low-volume production and re-engineering of battery protection systems (BMS), Li-Ion battery chargers and motor-control electronics for power tools.
- ▪ Smart BMS (3S–16S) pro Li-Ion / LiFePO4
- ▪ Algorithms for sodium-ion (Na-ion) cells
- ▪ 3 kW BLDC/PMSM driver with vector control
- ▪ IoT interfaces (CAN bus, Modbus, BLE, UART)
Custom Power Resistors
Manufacture of passive power components fully tailored to specific mechanical layouts, cooling requirements and current surges.
- ▪ Braking resistors for inverters and BLDC drives
- ▪ RC snubbers and discharge resistors
- ▪ Inrush current limiters
- ▪ Aluminium-housed and compound-filled resistors
Ignition Lead Sets & Coils
Traditional and performance automotive ignition cable systems designed for high mechanical loads, effective EMI suppression and high-temperature resistance in demanding environments.
- ▪ Silicone cables (8–10 mm) up to 260 °C
- ▪ Sets with copper cores and textile retro braiding
- ▪ Custom and private-label B2B / B2C
- ▪ Universal DIY sets
Test Stations for Final Inspection of Electronic Products
We design and manufacture custom test stations and fixtures for electronic product inspection. Each solution is tailored to the product, required test scope and manufacturing process – from simple fixtures for individual measurements to complex test stations with multiple instruments and automated control.
Our test stations automate electrical measurements, communication with the device under test and evaluation of its parameters. For microcontroller-based products, the process can also include programming and verification of the uploaded firmware. Individual inspection steps are controlled by our own test software and the results are evaluated automatically.
Measured and evaluated data can be stored for production records and subsequent traceability of individual products.
We automate electrical measurements, product communication and real-time evaluation of all critical parameters.
For microcontroller-based products, the automated cycle includes fast firmware programming and immediate code-integrity verification.
Measured data is stored for immediate digital production records and full traceability of every manufactured unit.
We design and manufacture non-standard mechanical parts and pogo-pin adapters in-house for maximum flexibility and speed.
When the product changes, a new machine is not necessarily required. Testers can be adapted by modifying the test script.
For electronics developed by our team, we provide the complete development chain – from the first PCB schematic to the final test station.
