V2X: vehicle-to-everything
Demand for electricity is expected to increase significantly in the future, with electric vehicle charging forecasted to be 20% to 30% of total demand on the electric grid in 20 years.
Fortunately, EVs can also be part of the solution through V2X, or vehicle-to-everything. V2X is an opportunity for PSE and our customers to work together to meet rising demand for electricity.
What is V2X?
Electricity is transferred to electric vehicles during charging. But, emerging technology found in some newer vehicles and chargers means this transfer doesn’t only have to work in one direction.
V2X is the transferring of electricity stored in the batteries of EVs to the electric grid, buildings, homes or other vehicles.
V2G = vehicle-to-grid
V2H = vehicle-to-home
V2B = vehicle-to-building
The benefits of V2X
In support of PSE’s Transportation Electrification Plan, we’re exploring the best ways to utilize V2X for the benefit of the electric grid and our customers. Those benefits include:
- Lower fuel expenses for commercial and residential customers
- Potential compensation for customers participating in vehicle-to-grid programs
- A more resilient and robust energy grid
- Backup power for customers via V2B and V2H
- Support for greener and more sustainable transportation
How V2X works
V2X allows battery-only electric vehicles to act as distributed energy resources, helping to reduce demand on the electric grid.
- Bidirectional charging: electricity flows both to and from the vehicle in order to contribute excess energy back to the electric grid during high-demand periods or to homes and buildings in times of need.
- Grid support functionality: the vehicle acts as a mobile battery storage system, supporting the electric grid during peak demand and enhancing reliability.
- Smart charging infrastructure: integration with smart charging systems allow for optimized vehicle charging schedules based on time-of-use rates, energy demand and more.
V2X FAQs
How does V2X help the power grid?
V2X can help provide backup power during outages, balance grid demand, support renewable energy integration, and reduce strain during peak usage periods.
Is V2X safe for my vehicle’s battery?
V2X systems are designed with battery preservation in mind and include protections to prevent excessive discharge or damage to your vehicle's battery. Be sure to check your vehicle’s warranty to understand any limitations pertaining to V2X.
When would my vehicle provide power to the grid?
Your vehicle would typically supply power to the grid during peak demand periods when the electrical system is under heavy strain. Your vehicle may also supply power during grid emergencies, offering valuable support when the electrical system needs additional resources.
Will I always have enough charge for my driving needs?
V2X programs always allow participants to set minimum charge levels and indicate when they need their vehicles fully charged.
