Power Quality of a bidirectional Electric Vehicle charger

At present almost all the electric vehicle (EV) charging equipment is unidirectional, that is Grid-2-Vehic1e (G2V). There is great interest in bidirectional electric vehicle charging equipment due to the benefits this may bring. However, there is a lack of real experience and information regarding this technology. This paper reports on the first stage of a project to remedy this. The first stage is laboratory testing of the technology and the second is deployment and field experience over a year of the equipment’s use in a domestic home. As shown the harmonic performance of the bidirectional charger is very good.
