Assessment of the Electromagnetic Radiation Exposure at EV Charging Facilities

As the number of electric vehicles (EV) increases, the number of EV chargers also increases. Charging infrastructure will be built into our close environment. Because of this, the assessment of the electromagnetic field exposure generated from the charger is an important issue. This paper valuates the electromagnetic field exposure of six EV chargers. To assess the level of exposure of EV chargers, the electromagnetic fields from six chargers were measured and analyzed. In addition, measured electromagnetic field exposure levels were evaluated against ICNIRP guidelines. Higher electromagnetic fields were measured with standard chargers than with fast chargers. For the fast charger in the charging state, the magnetic field increased with the charging current. Electromagnetic field exposures for all six chargers did not exceed standard limits. The results of the assessment of the electromagnetic field exposure of the six EV chargers will contribute to the establishment of standards for the evaluation of the electromagnetic field exposure of the EV chargers in the future.

Automated summary

As the number of electric vehicles (EV) increases, the assessment of electromagnetic field exposure from EV chargers becomes important. This study evaluated the electromagnetic field exposure of six EV chargers by measuring and analyzing their electromagnetic fields. The exposure levels were compared against ICNIRP guidelines and it was found that standard chargers emitted higher electromagnetic fields than fast chargers. However, all six chargers' electromagnetic field exposures were within standard limits. This assessment will contribute to establishing future standards for evaluating EV charger electromagnetic field exposure.
