  Bidirectional electric vehicle (EV) charging is a technology that is gaining
rapid popularity due to its ability to provide economic and environmental
benefits to both EV owners and power system operators (PSOs). Using the EV as a
flexible source of energy, an EV owner can provide power to homes/buildings, or
even participate in grid services such as demand response and frequency
regulation. However, there is a lack of real-world testing and validation for
bidirectional charging technology, particularly in the residential segment. As
such, this paper presents real-world field testing of a bidirectional EV
charger deployed in a home. Control software is developed to dispatch the EV
according to static setpoints, as well as automated load following, and its
accuracy and responsiveness is reported on. The results of the testing with the
charger and 2019 Nissan Leaf combination indicates a responsiveness of 6-8
seconds and accuracy of over 99%, which suggests feasible participation for
applications such as load following, arbitrage, and demand response.
