Easelink, based in Graz, Austria, has developed the "matrix charging" system, which consists of two components. A charging pad is connected to the mains is installed in the parking spot. A connector on the bottom of the e-car drops down when the car is parked over the pad. The charging process starts automatically, so the driver does not have to connect a cable – like inductive charging, but with 99 percent efficiency and up to ten times the charging power.During the development process, the design engineers created a production-ready component by means of several prototypes. To minimise expenses while ensuring high quality, they used the igus 3D printing service.
