Modelling of Static Wireless Electric Vehicle Charging and its Impact on a Typical GB Distribution Network

This project set out to model and build a prototype wireless charger and to investigate the impact of wide spread uptake of wireless EV charging in the UK. A network model network was created and a number of charging scenarios defined. On street, car park and home charging scenarios were modelled. The voltage, current and power losses were found using a defined charging behaviour characteristic. It was found that novel charging method that can take place using a wireless charger reduced the impact of EVs. Initially, a 500 W wireless charger was modelled. Subsequently, a smaller (prototype) coil was investigated in order to compare the COMSOL model to the prototype coil. A test frame with movement in X, Y and Z planes was designed and built in order to effectively and accurately test the wireless charging coil. The results of the COMSOL and prototype investigation showed similarities in the field characteristics. However, the model showed higher levels of magnetic field density.
