The expected high penetration of battery chargersfor electric vehicles (EV) in electric networks is foreseen as apotential problem for power quality. Battery chargers are non-linear devices that inject harmonic currents and pollute networkvoltages. Thus, their harmonic emissions must be analyzed andreduced by harmonic mitigation techniques to avoid futureproblems. This paper analyzes and reports some real casemeasurements of harmonics injected by single- and three-phasebattery chargers and their attenuation using line chokeinductances.
