The main objective of STABALID is to support the deployment of safe Li-ion stationary batteries with a cell size larger than 10 Ah and systems larger than 1 MWh. This will be done by developing, testing, validating and disseminating a new international standard for stationary battery tests during the course of the project.
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.
