WebOct 1, 2015 · The standards applied to the low-power EV chargers are IEC 61000-3-2 [17] and IEC 61000-3-4 [18], which set limits to the harmonic emissions generated by the charger. Another study based on practical measurements of charging commercial EVs [8] presents a maximum THD I of 17.3% for a level III charger at the end of the charge, and … WebFeb 3, 2024 · Hello @HelvinHermanT. If it's an AC charger, the impact should rather be on the EV side (the car), not the EVSE (charger). The cos Phi generator is on the EVSE side for DC chargers. Then, it would depend on the EV model, but we can estimate Power Factor between 0.8 and 1, with a typical current distortion rate is around 20%.
