Safety Testing Approaches for Large Lithium-Ion battery systems
Start date: Oct 1, 2012,
End date: Mar 31, 2015
The STALLION project develops and validates a safety framework for large stationary Lithium Ion batteries in all stages of their life cycle (commissioning, transport, installation, operation, maintenance, repair, decommissioning, recycling). It offers a unique approach by relating safety issues to root causes at all levels of the system (material, cell, module, pack, system). This two-axis safety assessment approach - all stages of the life cycle and all levels of the system - is experience-based through the involvement of partners active at all levels of the system and an advisory board consisting of organizations with experience in the application. This guarantees a thorough covering of all relevant cross-cutting issues.The project will also establish the state of the art in the relevant technological areas like materials, cell architecture and detection methods. Based on this benchmark that will be available in the market of large stationary battery systems in coming years, mitigation measures will be defined to deal with the identified risks and bring the system within the previously defined safe boundaries.All measures developed will be validated empirically. Laboratory tests on both safety and performance will be executed on materials and cells. Through our partners and Advisory Board, several large, commissioned grid-connected batteries are available for analysis at the system level. The gap between the cell level and the system level is covered by modeling the safety and thermal behavior.Results will lead to a handbook on comprehensive and generic safety measures for large grid connected batteries. Through the standardization organizations in our AB, this handbook will be proposed to the relevant standardization bodies and it will be actively distributed to industry. 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.
