Key challenges on the path to DC fast charging 3 Grid connection: High power demand at DC charging spots Requirements to the grid EV fast charging solutions Increasing number of renewable energy sources leads to volatile energy supply. Energy has to be buffered to offer continuous supply. Decentralized energy supply changes power demand and direction. Chargers shall be connected to the middle voltage grid. Intelligent grid connection and real time data are needed. Usage of energy buffers to adapt power supply and demand. Buffers, intelligent charging and middle voltage connections for DC chargers are the solution Slide 10
