This paper presents a smart metering network for monitoring energy consumption and power quality of building integrated electric vehicle charging network. The smart metering network consists of smart metering devices, a ZigBee communication network, and a central system for power calculation and power quality analysis. The smart metering device captures current and/or voltage waveform and performs waveform compression function and feature extraction. The waveform compression and feature extraction algorithm is developed from FFTW algorithm and DWPT algorithm.
