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 The company had only one outdated prototype available for evaluation, with no technical documentation.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
-
