This is achieved through advanced power electronics and control systems that manage the flow of electricity in both directions. The bidirectional charger is typically installed in the home and connected to both the EV and the home's electrical panel. When the grid is providing power, the charger functions like a regular EV charger, drawing electricity from the grid and charging the EV's battery. However, when the grid experiences an outage or during peak demand periods, the charger automatically switches to V2H mode and begins drawing power from the EV's battery. This power is then fed into the home's electrical panel, which distributes it to the various circuits and appliances in the house. The switching between grid power and EV battery power is typically seamless and automatic, ensuring that there is no interruption to the home's electricity supply. To ensure safety and prevent backfeeding electricity into the grid, V2H systems are equipped with sophisticated control systems and isolation devices. These systems continuously monitor the grid voltage and frequency, and if any anomalies are detected, they automatically disconnect the EV from the grid to prevent any potential hazards. In addition, V2H systems typically include a manual disconnect switch that allows homeowners to manually disconnect their EV from the grid in case of an emergency. The amount of power that an EV can supply to a home through V2H technology depends on several factors, including the size of the EV's battery, the capacity of the bidirectional charger, and the home's energy consumption. Typically, V2H systems can provide enough power to run essential appliances and systems in a home, such as lighting, refrigeration, heating, and critical medical equipment.
