The article is describing the intentional use for Li-On batteries in the scope of the E-LAND project. The E-LAND project is developing a toolbox that is helping the energy islands (i.e. a community of users that produces and uses part or all of their energy needs) to manage and optimize their energy consumptions and energy costs. The topics addressed in this article are related to the E-LAND Project and toolbox, batteries safety in regards of battery ageing, degradation and life, lifetime concerns, battery stability. A second focus in this article is related to security of the battery. Exposure of existing legacy operational infrastructure, asset hardening and new integration requirements, concerns in a multi-cloud environment, and advice for asset hardening and integration requirement in the scope of the project are discussed.
