DENSO and TÜV Rheinland Japan validate battery passport for AESC energy storage products ahead of EU mandate

DENSO and TÜV Rheinland Japan have validated a battery passport for AESC Group's energy storage products using actual data, confirming its compliance with the EU Battery Regulation ahead of the February 2027 mandate. DENSO provided the technological foundation for generating and managing battery passports, which enables access to battery information via QR codes whilst maintaining data security. TÜV Rheinland Japan, acting as an independent certification body, verified the system's regulatory compliance and data reliability based on EU standards. AESC supplied data from its existing energy storage systems business and has implemented sustainability measures across its supply chain, including battery recycling frameworks. The validation confirmed the solution's practicality for real-world business integration. The companies will now expand their efforts to include AESC's automotive batteries for broader market implementation.
