Analysis On-Board Charger to the Influence of Power Quality

Abstract:

In this paper, one on-board charger in the charging station will be used to test its charging process. We screen the data which has the typical characteristics of power parameters from test data, and compared with the national power quality standards. We can get the following conclusions: (1) The electric car battery is capacitive load, it may transfer the reactive power to grid in the process of charging;(2) The test data imply that frequency deviation, power factor and VTHD e.g. indexes are qualified;(3) On-board charger is mainly produced the odd harmonics in the process of charging, with the increase of harmonic frequency, harmonic contain lower rate;(4) In practice, harmonic mainly reflects on the current, voltage only has a small distortion.
