STABALID:

STAtionary Batteries LI-ion safe Deployment

 

The development of the Smart Energy Networks is a key priority to facilitate the transition to a more sustainable energy supply in Europe. Li-ion battery is a very promising technology for improving the penetration of renewable energy sources (RES) in the energy mix and enabling a better management of energy in the European grid. The overall objective of the STABALID project is to facilitate the deployment of safe stationary batteries with energy content over1 MWh and cell size larger than 10 Ah. To this end, the consortium will developa new testing procedure for stationary batteries that will become a new international standard document for this kind of energy system. The safety testing procedure will be developed based on a detailed risk analysis and thereview of international existing standards (including those in preparation)applicable for stationary batteries, and taking into account the on-going research work on Li-ion batteries and on Electric Vehicle charging at EU (e.g.HELIOS, MERGE, SOL-ION projects) and national levels. The new standard will be developed to guarantee safety during the whole life cycle of the batteries. In addition, the consortium will propose a strategy and roadmap to establish aharmonized regulatory framework in order to allow a safe implementation, operation and end of life of large Li-ion batteries for grid applications. The project and in particular the testing procedure will be developed in close cooperation with Japan thanks to collaboration with selected projects financed by METI and NEDO. STABALID project is technically led by a world leading manufacturing company, SAFT, and involves a utility company as representative of end-users, EDPD, as well as reference organizations for safety inspection, testing, certification, and for integrated risk management. Thus, the consortium ambition is to have the new standard adopted during the course ofthe project using established connection with IEC committees.

 

 

The STABALID project has the following specific S&T objectives:

• to apply a recognised risk assessment approach and identify the scenarios to define the safety features of the system;
• to determine the potential aggressions induced by the environment on the battery system and those from the battery system on the surrounding environment;
• to define the minimum safety functions that need to be implemented on the battery design both in terms of electronic control and in terms of mechanical design;
• to define the proper test methodology (test nature and test procedure) in order to verify that the safety functions implemented enable to cover the various safety issues identified;
• to validate the pertinence and robustness of the test methodology by performing the protocol in two recognized European safety testing and certification companies;
• to transfer the proposed methodology into a documentary standard and to harmonize the proposed standard at worldwide level;
• to assess the environmental regulatory frameworks existing in various countries and the corresponding barriers for the deployment of stationnary batteries.

Following this process will ensure to release on the market reliable batteries systemswith a clear and robust safety status based on a proven test methodology. Thisis a large improvement compared to the current process of standard definitionused in the lithium-ion battery field.

The STABALID (STAtionary Batteries LI-ion safe Deployment) project will closely collaborate with the STALLION (Safety Testing Approaches for Large Lithium-Ion Battery Systems) project that aims at setting up a complete framework of methodologies and protocols for safety testing of stationary Li-ion batteries for large-scale grid applications. STALLION will incorporate the state of the art in the relevant technological areas like materials, cell architecture and detection methods.
Results will lead to a handbook on comprehensive and generic safety measures for large grid connected batteries. STALLION will contribute to the standardization framework for large-scale Li-ion battery testing and to a faster and safer deployment of Li-ion Batteries for grid application.
