■ Company wins both international cyber security and functional safety certifications

■ Certified BMS to be supplied to major European automaker

SEOUL — SK On, a leading global battery and trading company, announced today it became the first battery maker in Korea to earn an international Cyber Security Assessment (CSA) for its Battery Management System (BMS), reinforcing its technology credibility.

The company also secured a Functional Safety Management System (FSMS) Level 3 certification, which further strengthens trust in its commitment to safety and reliability.

SK On, part of South Korea’s SK Group, received both the CSA and FSMS Level 3 certifications from TÜV Rheinland, a leading global testing and certification organization.

SK On said its BMS is the first automotive controller in Korea to achieve CSA certification, confirming compliance with strict international standards for vehicle cyber security. The certification is granted to products that are developed and validated under a Cyber Security Management Concept (CSMC).

With the CSA certification, SK On demonstrated that its battery system meets the high security standards required by global automakers. The certified BMS will be supplied to a major European automaker together with SK On’s battery cells and modules.

The FSMS Level 3 certification, based on the ISO 26262* standard, recognizes companies that systematically manage functional safety risks throughout the entire product lifecycle, from design to production and beyond. SK On is also the first Korean battery manufacturer to reach this level for its BMS technology.

*ISO 26262: An international standard for systematically managing functional safety in automotive electrical and electronic systems.

In May, SK On earned Cyber Security System (CSMS) Level 3 certification under ISO/SAE 21434**, proving its ability to manage cyber security risks across automotive software and electronic components.

**ISO/SAE 21434: An international standard for managing cyber security risks in automotive electrical and electronic systems.

The CSMS certification aligns with the United Nations Economic Commission for Europe’s UN Regulation No. 155, which requires new vehicles sold in 56 UNECE member countries—including the EU, North America, and parts of Asia—to comply with strict cyber security requirements.

“The certifications prove SK On’s technological leadership and robust management systems for both cyber security and functional safety,” said Ko Jeong-woon, Head of System Generic Technology Development at SK On. “We will continue to expand the scope of these solutions in close collaboration with global automakers.”​
