The European Commission has erected directives and is implementing policy to establish a more circular economy related to batteries. This should ultimately lead to less reliance on critical raw materials, more ethical sourcing of raw materials, boost second life utilization of batteries and minimum environmental impact due to disposal. As of February 2027 the policy enforces certain batteries that enter the European market to feature a battery passport.

Research institutes and industry are now working on developing the technology for timely market introduction. TNO and NXP have been working together in the national project: Green Transport Delta – Electrification to develop and demonstrate a reference battery system that is capable of running a battery passport. TNO developed the cloud solution which manages the storage and access rights management to the battery data. ELEO provided the battery system and NXP supplied a BMS (Battery Management System) which were all integrated for proof of concept testing.

The SBPD project will take a next step to focus on data security aspects. The effectiveness of the battery passport strongly depends on the quality of the data within the passport. To fulfil this requirement the project implements and demonstrated measures on hardware and software side. The secure element in the BSM must ensure that tempering with sensors and data is detected and registered and that data is securely transmitted into the battery cloud. TNO will implement battery state algorithms that support a model based detection of tempering out of normal degradation of the battery.

The developed setup is demonstrated and disseminated by means of webinars. In the requirements and evaluation phase of the project industrial project partners, ELEO, Cleantron and Hyster-Yale will provide feedback. In this way the project will directly impact the competitiveness of Dutch industry.
