California legislation: Electric cars must have V2G charging
Created on 09.05
2024-08-31-The U.S. California S.B. 59 amendment was approved.
American independent research firm Clear View Energy stated that the bill represents a “less prescriptive alternative” to similar bills passed by the California Senate last year. The new law grants greater discretion to the California Energy Commission to mandate two-way electric vehicle charging capabilities. However, given the size of the California auto market, S.B. 59 could impact the speed and scale of V2G-supported vehicles nationwide. This means that the widespread adoption of CCS1 standard electric vehicles and V2G-enabled charging stations has become a key factor in driving market demand.
In addition, in May, Maryland enacted a package of clean energy legislation to stimulate the adoption of residential and commercial solar power to meet the states requirement that solar power account for 14.5% of total electricity generation by 2028. The legislation requires Maryland utilities to develop plans for next years two-way electric vehicle charging （Bidirectional EV charging）and virtual power plant networks, as well as implement time-of-use pricing by 2028 to incentivize off-peak electricity use. Shortly after the package was enacted, a Colorado law requirement mandated that the states largest utility, Xcel Energy, create a performance-based compensation tariff VPP plan by February, while also taking steps to simplify its grid interconnection process and upgrade distribution networks to alleviate capacityconstraints. Xcel and Fermata Energy are also seeking to build a potentially path breaking bidirectional EV charging pilot program project in Boulder, Colorado, where the pilot will facilitate Xcels understanding of the bill impact and resilience advantages of two-way charging assets.
What is V2G technology
V2G, or Vehicle-to-Grid (vehicle to grid), is an innovative technology that allows electric vehicles (EV) to interact with the grid in both directions.
The core of the technology is that electric cars can not only draw power from the grid to recharge, but also feed energy stored in their batteries back into the grid when needed, enabling a two-way flow of energy.
The realization of V2G technology requires the support of smart grid, smart charging piles and electric vehicles with V2G function.

Key advantages of V2G technology
- Increase grid flexibility: V2G technology uses the battery of electric vehicles as a buffer for the grid, which can provide power when the grid load is too high, helping to reduce peak and valley, and improve the stability and reliability of the grid.
- Promoting renewable energy consumption: V2G technology can store excess wind and solar energy
- Economic benefits: Electric vehicle users can earn additional revenue by selling electricity to the grid, reducing the cost of using electric vehicles, while grid operators can also reduce operating costs through V2G technology.
- Participation in the energy market: V2G technology enables electric vehicles to participate in the energy market, bringing economic incentives to owners through energy trading and improving the efficiency of the entire energy system.
Application of V2G technology overseas
- Many countries and regions around the world are conducting research and application of V2G (Vehicle-to-Grid) technology
- In the United States, apart from California completing legislation, other states such as California and Virginia are also promoting the development of V2G technology to support grid stability and renewable energy integration. Models like the Nissan Leaf and Ford F-150 Lightning have already supported V2G, and Tesla has announced plans to equip all its vehicles with bidirectional charging
- Germanys Bidirektionales Lademanagement-BDL project is a study of how two-way electric vehicles
- The UKs Electric Nation Vehicle to Grid project is studying how V2G charging interacts with the grid and how it can serve the grid.
- The Dutch “PowerParking” project uses solar carports to provide charging services for electric vehicles and explores the application of V2G technology in smart energy management.
- Australias Realising Electric Vehicles-to-grid Services (REVS) project shows how electric vehicles can provide frequency control services to the grid through V2G technology.
- Portugals Azores project tested V2G technology in the Azores, using batteries from electric cars to store energy at night when wind power is surplus.
- Swedens “V2X Suisse” project explores the application of V2G technology in fleets and how to provide flexibility services for the grid through V2G technology. The Paker project, a collaboration between the Technical University of Denmark and Nissan, leverages electric vehicles to offer frequency regulation auxiliary services, demonstrating the commercial potential of private electric vehicles providing such services during nighttime parking. At OSL Airport in Norway, V2G charging stations and V2G certified vehicles (such as Nissan Leaf) have been cycling for pilot studies to estimate the flexibility that EV batteries can potentially provide.
- Japan and South Korea are also advancing the development of V2G technology: Japans KEPCO has developed a V2G system that allows electric vehicles to supply power to the grid during peak demand times. Korea Electric Power Corporation (KEPCO) is conducting research on V2G technology aimed at optimizing the power supply through battery storage systems in electric vehicles. The market size for its vehicle-grid integration technologies and services is estimated to reach $700 million (747 billion KRW) by 2026. Hyundai Mobis is also the first company in South Korea to receive approval for bidirectional chargers from a V2G testbed.
V2X technology
V2X refers to the transmission of electricity stored in electric vehicle batteries to the grid (V2G), buildings (V2B), homes (V2H), loads (V2L), or farms (V2F). V2X technology can be used to regulate different energy markets, thereby reducing costs and carbon emissions by storing energy during off-peak hours and exporting it during peak hours using batteries in electric vehicles.
V2G technology application scenarios
Support for vehicle and pile communication standard V2G
Europe and the United States currently use three main electric vehicle charging communication standards: the widely used CCS communication standard, TeslasSupercharge NACS standard, Japans CHAdeMO standard, and so on. These standards have now been compatible with orderly charging and V2G technology in different versions.
