Initial Situation
A company from the energy storage sector approached TPS Elektronik with a critical challenge. They were developing a next-generation battery management platform for use in both grid-scale storage and industrial applications. To gain CE approval and comply with international standards, the devices needed to pass strict electromagnetic compatibility (EMC) compliance testing.
The previous supplier had limited expertise in EMC testing and failed to achieve compliance. The company had only one outdated prototype available for evaluation, with no technical documentation. This prototype failed all EMC compliance tests, and severe interference was detected during measurements, making the product unsuitable for market introduction.
Key Challenges
The main challenges the customer faced included:
Limited knowledge of how to integrate EMC requirements into product development
No access to professional EMC testing equipment
Need for an experienced partner in EMC testing services
Specific requirements for both industrial electronics and battery EMC testing
Necessity of a shielding and housing redesign to meet EMC compliance
The TPS Solution
TPS Elektronik developed a structured solution to bring the device into compliance:
New Electronic Design & Layout
Redesigned the circuit and PCB layout to significantly improve EMC behavior
Applied design guidelines based on international EMC standards to minimize emissions and maximize immunity
Professional Testing & Validation
Performed full EMC compliance testing using state-of-the-art equipment
Supported the customer with conducted emissions, radiated immunity, and shielding effectiveness tests
Battery-Specific Testing
Conducted targeted battery EMC testing to meet the latest energy storage standards
Validated charging and discharging cycles under EMC stress conditions
Shielding & Housing Redesign
Developed a new housing concept with improved shielding materials
Integrated filtering and grounding strategies to reduce conducted noise
Compliance & Certification Readiness
Prepared the device for CE approval through final EMC validation
Delivered complete documentation for long-term compliance in global markets
Results
The collaboration between TPS Elektronik and the customer achieved the following:
Full compliance: The redesigned product passed all required EMC compliance tests
Enhanced battery reliability: Battery EMC testing supported safe integration into grid-scale and industrial storage systems
Market readiness: The device obtained CE certification within the planned project timeframe
Future-proof design: With optimized shielding and proven EMC design, the platform is ready for future product upgrades
Conclusion
This project highlights TPS Elektronik’s expertise in EMC compliance testing and related services. By combining advanced testing methods, professional use of equipment, and deep knowledge of EMC requirements, TPS Elektronik delivered a complete solution.
From battery EMC testing to full-system validation, TPS Elektronik helps ensure that products not only achieve EMC compliance but also demonstrate long-term reliability in demanding applications.
Through this successful partnership, the customer was able to modernize its product line, secure CE approval, and enter the global market with a compliant and competitive solution.
