This energy system charges the batteries of parked cars with solar energy. This stored energy can be discharged if it is needed elsewhere in the grid, for example street lighting at night. Parking spaces and parked cars thus have a useful function. This innovation also contributes to stabilising the load on the electricity network – peak shaving – so that investment in replacement is less urgent.
The energy grid is faced with increasing peaks in the energy that is demanded, due to the charging of electric cars. Also there is an increasing peak in the energy that is returned to the grid through generation with solar cells or wind turbines. The PowerParking’s smart grid acts as a buffer in this.
