High-performance charging system with integrated buffer storage - Power 400

In the Power 400 project, Fraunhofer ISIT, together with various cooperation partners from industry and science, is developing and building a buffer-stored 400 kW fast charging station for electric vehicles, which will be tested under real conditions after completion. At the charging station, it should be possible to quickly charge electric vehicles simultaneously at any time without destabilizing the public power grid.

Powerful charging system

The high energy demands of the powerful charging system are decoupled from the power grid via a battery-electric storage system developed at Fraunhofer ISIT, which can even have a grid-stabilizing effect on the power grid if required. Power 400 is thus equally important for the mobility and energy transition.

Fast rechargeable batteries

Another focus is on developing battery technology that enables vehicles to be charged quickly in less than ten minutes. The disadvantages associated with fast charging processes in terms of battery life and safety will be drastically reduced as a result of this new technology. For the system tests with 400 kW, a test stand with a mobile high-performance battery is being developed based on the new battery technology, since current electric vehicles cannot currently accommodate these charging powers.

Project results, project partners

Through the intelligent use of stationary and specially developed mobile storage systems with optimally matched characteristics, the project has advanced the integration of renewable sources into the energy supply grid and the increased use of electric vehicles in metropolitan areas in a sustainable and efficient manner.

In the Power400 project, battery cell manufacturers, research institutions and universities are working closely together. This collaborative project is an important step toward decarbonizing the public transportation system and thus protecting the climate.
