Enabling an Intelligent, Bidirectional Grid

Electric vehicles (EVs) are no longer just consumers of energy, they can also act as distributed energy resources. By integrating EVs into the grid, cities and utilities can create a smarter, more responsive energy ecosystem.

Vehicle-to-Grid (V2G) Integration

Modern EVs, autonomous vehicles (AVs), and urban transit systems have the potential to become part of a highly intelligent, bidirectional urban grid. Unlike conventional charging, V2G allows vehicles not only to draw power from the grid but also to store and discharge energy back when it’s needed most.

Currently, most EVs are idle or fully charged when the grid could benefit from their stored energy. V2G bridges this gap, making EV batteries a distributed source of electricity for peak demand periods, emergency supply, or grid stabilization.

Bidirectional Wireless Power

Bidirectional wireless charging solves the access problem for V2G. Whenever a vehicle is parked over a wireless charging pad, it can automatically participate in V2G operations, without any driver intervention. By creating a network of vehicles that can intelligently charge or discharge, cities can:

• Smooth out peak electricity demand
• Integrate renewable energy more efficiently
• Tap distributed energy resources on demand

This approach turns parked EVs into a massive, decentralized energy storage system, enabling more flexible and resilient urban energy management.

Energy Arbitrage:

Maximizing Value from Stored Energy

Energy arbitrage is the practice of storing electricity when prices are low and using or selling it when prices are high. When paired with V2G-capable EVs, energy arbitrage unlocks significant financial and operational benefits for both consumers and utilities.

How it works:

• Charge when cheap: Store energy during off-peak hours or when renewable generation exceeds demand.
• Use during peak: Draw from stored energy instead of buying expensive grid power during high-demand periods.
• Sell back to the grid: In markets that allow it, sell stored energy at peak rates, creating a revenue stream from the price difference.

Benefits of V2G and Energy Arbitrage

• Lower electricity costs: Consumers save money by using stored energy during peak hours rather than purchasing expensive grid power.
• Enhanced renewable energy value: Excess solar or wind power can be stored and used later when it’s more valuable.
• Grid stabilization: Distributed storage helps balance demand and reduce reliance on peaker power plants.
• Scalable urban energy management: A network of V2G-enabled vehicles creates a flexible, intelligent grid that can respond to changing energy patterns in real time.
