Measurement of inductive charging for electric vehicles

Inductive charging is a contactless technique that is coming for all electric vehicles. It gives great benefits to todays's charging techniques. One will, for example, be able to charge during travel, have smaller batteries, be less dependent on peripheral equipment and get a high-efficiency power transfer.

The MICEV project (Metrology for Inductive Charging of Electric Vehicles) will promote the development of IPT (Inductive Power Transfer) for charging electric vehicles partly by developing techniques for measuring IPT efficiency and partly by demonstrating that IPT meets the safety standards that exist for human exposure of magnetic fields.

A number of facilities will be built where sensors and power measurement technology manufacturers can calibrate their instruments under realistic conditions in the 20 kHz to 150 kHz frequency range.

Measuring plants and documentation for standardization are created

Comprehensive and validated computer simulations and measurements of human exposure to magnetic fields from IPT systems in electric vehicles are developed as well as test protocols for field studies and static and dynamic radiation calculations. This will form the basis for future standards for ITP stations.

New measuring possibilities will be created at national measuring institutes with direct relevance for accredited laboratories as well as manufacturers of magnetic field, electric current, voltage and power meters.

Electric vehicle manufacturers and their subcontractors, manufacturers of forklifts and automatic vehicles in industrial environments will also benefit from the development.

The results will be used to support standardization through participation in seven working groups within DKE, EURAMET, IEA, IEC and ISO.
