Germany-wide first Tesla-Megapack is starting test operation

We can now finally announce: At LLEC, we have put the long-planned high-energy battery system into test operation on our campus. With 24 tons of weight, a maximal power of 595 kW and a usable capacity of 2.616 kWh, the Tesla-Megapack is the first stationary battery system of its kind in German.

The Tesla Megapack stores energy when demand from the grid is low and feeds energy back into the grid when demand is high. The battery system is integrated into the medium-voltage network to optimize operations. The LLEC's higher-level cloud-based control platform controls the load flows between energy generated from photovoltaics, demand usage and grid requirements in order to relieve the load on the power grid and minimize electricity costs. In addition, part of the battery capacity is reserved for the nearby school laboratory as part of the LLEC sub-project "JuPilot".

In addition to stabilizing the power grid, the LLEC project team plans to carry out various load profiles experimentally and imitate them with model simulations down to the cell level. Using a digital twin, researchers gain insight into the internal components of the high-energy battery, which allows long-term properties of the battery system and cell aging to be examined under different types of use. The investigation of different possible uses of the battery system should also provide information about how battery systems can be further optimized in the future.

The Tesla Megapack is part of the entire LLEC project with the aim of demonstrating and researching innovative energy technology together with industry. Further detailed information about the research work in the field of battery storage systems can be found here
