Magnetic field distribution Around resonant coils After a preliminary study and an evaluation on an axisymmetric charging station, two charging stations for inductive charging were modeled. A preliminary tuning made using multiple models has been carried out in cooperation with INRIM, POLITO, RISE, SPEAG and NPL with the participation of AALTO University and UNICAS. Validation was made for comparison with different calculation codes and during 2019 an experimental validation will follow.
Electromagnetic simulation of a charging station with a real car bodyElectromagnetic simulation of a bus charging station including the bus body A real car body and a bus body have been setup for electromagnetic and dosimetric simulations in a finite element environment. The generation system is included in the model. The model is current driven. Magnetic induction levels were investigated for three different positions of the charging coils. A bus model including the charging station coils and metals (24.5 Milion tetrahedral elements) requires about 16 hours and 30 minutes to be solved (dosimetric computations excluded) with the followig system: Dell(R) Server PowerEdge R740, OS: Windows(R) servers 2016, Double Processor Intel(R) Xeon(R) Gold 6130 CPU @ 2.10GHz, 2095 MHz, total 32 Core(s), 32 Logical Processor(s), 256 GB ram (300 GB SAS).
New calibration facility for MF setup at NPL A new calibration system to characterise magnetic field sensors has been developed and setup at NPL (UK), also using the experience present at the project NMIs. The current capability have been extended up to 150 kHz, up to 100 uT. The facility will be validated through an intercomparison involving three partners during spring of 2019.
The new reference resistive-capacitive divider (RCVD) realized at INRIM Voltage injector (INJ)Generation of DC+AC voltage through a voltage amplifier (AMPL), injector (INJ) and DC calibrator (CAL) NRIM realized two new reference resistive-capacitive voltage dividers, operating in DC and AC from 10 kHz up to 200 kHz. The ratio error is lower than 1000 ppm and the phase error is lower than 400 rad at 100 kHz. The divider is stable and repeatable. This allows one to define a calibration matrix of the device bringing its relative measurement uncertainty lower than 0.510-3 up to 200 kHz. Two new voltage Injectors have been realized and characterized and a new procedure for voltage calibration of meters-dividers, including the phase error up to many hundreds of kilohertz, has been experimented.
Calibration facilty for electric quantities, setup at PTB PTB has setup a circuit for the implementation of combined DC and AC power generation. The system implements the new reference voltage divider, is flexible and can generate independent signal forms for current and voltage signals. It is able to reproduce recorded real signal forms. The correction of the errors of the ADCs and the current and voltage sensors is being implemented. The system performs the calculation of: i, u, S, P, Q, FFT, reads and compares with the DUT, logs the measured values.
Safety evaluations of electrically short implants (Link)Dosimetric simulation (SPEAG) SPEAG realized and published a new mechanistic model that provides valuable support for the formulation of a general approach for use in safety guidelines and standards, which is applicable for exposure to EM fields over a large frequency range including IPT and MRI. It also suggests a possible approach for the identification of worst-case implant routing conditions. SPEAG is also setting up advanced poseable human anatomical phantoms (Virtual Population, ViP) for the project MICEV.
