Abstract
In this paper, a Goertzel-based algorithm was proposed to calculate the amount of power by estimating the harmonic components generated during charging of the electric vehicle up to a very high order, allowing it to be applied to a low-cos electricity meter with low computing power. Using the proposed algorithm, it is verified through simulation for a simple example signal that even large-order harmonics can be sufficiently considered when wattage is measured.
