Vehicle-to-Home (V2H)

Vehicle-to-Home (V2H) is a technology that enables electric vehicles (EVs) to supply power to a home, using the energy stored in the vehicle’s battery. This process involves bidirectional charging, where the vehicle can both receive energy from the grid and discharge energy back to the home, providing a backup power source and potentially reducing electricity costs.

V2H technology leverages the substantial battery capacity of EVs to enhance home energy management. By using a bidirectional charger, the EV can store excess energy generated during periods of low demand or from renewable sources like solar panels. This stored energy can then be used to power the home during peak demand times, outages, or when electricity from the grid is most expensive. 

The implementation of V2H requires several components: a bidirectional charger, smart energy management software, an appropriate energy metering system, and the capability to isolate the home from the grid (islanding) during power outages. The bidirectional charger converts the DC power stored in the EV battery to AC power suitable for home use. Smart energy management software controls the energy flow, ensuring optimal use of stored power and seamless switching between grid and battery power. 

V2H offers numerous benefits, including increased energy self-sufficiency and cost savings. Homeowners can take advantage of variable electricity pricing by charging their EVs during off-peak hours and using stored energy during peak times, thus lowering electricity bills. Additionally, during power outages, V2H provides a reliable backup power source, maintaining critical home functions without the need for separate generators or storage batteries.
