This paper proposes an operation mode of an EV Battery Charger with V2H system mode. For such purpose of these vehicle-to-home (V2H) operation mode we adapted an on board bidirectional battery charger prototype to allow the Grid-to-Vehicle, Vehicle-to-Grid (V2G) operation modes. Along the paper are presented the hardware topology and the control algorithms of this battery charger. The idea underlying to this paper is the operation of the on-board bidirectional battery charger as an energy backup system when occurs a power outages. For detecting the power outages were compared two strategies, one based on the half-cycle RMS calculation of the power gird voltage, and another in the determination of the RMS value based in a Kalman filter. The experimental results were obtained considering the on-board EV battery charger under the G2V (Grid-to-Vehicle), V2G (Vehicle-to-Grid) and V2H (Vehicle-to -Home) operation modes. The results show that the power outages detection is faster using Kalman filter up to 90% than other strategy. This also enables a faster transition between operation modes when a power outage occurs.
