Project abstract

The power grid sector is facing severe challenges when it comes to stability in the power grid. Due to the development in the electromobility sector lithium-ion batteries are now a possible solution to install for stationary energy storage solutions. The flexibility, energy capacity and fast response time of lithium-ion batteries enables a unique possibility for power grid services.

This project is focused on understanding how batteries are being used when providing power grid services, and how this affects the battery when it comes to battery degradation or aging.

A battery lifetime study of a single cylindrical cell is being performed at KTH where the battery aging is being analyzed throughout the battery cycling life. One goal is to understand how battery aging is affected when several service cycles are combined, compared to single service use.
