Layout and operation of a non-contact charging system for electric vehicles

Actually, there is a controversial discussion in automotive industry if the deployment of inductive power supply is able to avoid the disadvantages of conductive vehicle charging systems. Available charging systems for electric vehicles use wires to connect the vehicle to the grid. This leads to several disadvantages such as vandalism and additional effort for the driver. Furthermore, loose or faulty cables are a safety risk. As an alternative, non-contact charging of electric vehicles allows for a simple, reliable and safe charging process. It improves the user acceptance and contributes to the integration of electric vehicles into the market. Thus, the availability to the grid is increased, which offers a higher degree of flexibility for the storage management.

Three phase high power contactless power supply for harbour automated guided vehicles

To improve power density of a primary system, several different ways to reach to goal are possible. On way is to increase the primary phases up to a decent number. Increasing the number of primary coils has much advantageous compared to a single phase topology such as increased power density and lower flux density at the outskirts. In this paper a short overview of the whole energy transfer chain will be done, before a finite element design will be shown. The layout for the CPS System is done at an air gap of 300mm. In a later section, the simulation results are compared with the prototype measurements.
