The New War of the Currents - CleanTechnica
The article "The New War of the Currents" from CleanTechnica draws a parallel between the historic battle over electrical power standards between Edison’s Direct Current (DC) and Tesla’s Alternating Current (AC) and the current debate surrounding bidirectional charging technology in electric vehicles (EVs). EVs, acting as mobile batteries, have the potential to support electricity grids by storing renewable energy and feeding it back when needed, a concept known as vehicle-to-grid (V2G). Despite promising pilot projects by companies like Octopus, BYD, EON, BMW, Mobilize, and Renault, widespread adoption of V2G is hindered by a lack of standardization in charging technology. The core issue lies in the incompatibility between the grid’s AC power and the EV battery’s DC power, requiring inverters to convert electricity flow directionally. Some manufacturers, such as Renault and BYD, integrate bidirectional inverters within the car, enabling affordable AC wallbox chargers to handle V

The Massachusetts Clean Energy Center (MassCEC) has launched a pioneering program to provide free bidirectional electric vehicle (EV) chargers to selected participants, including school districts, municipal projects, and residents. This initiative aims to accelerate the adoption of Vehicle-to-Everything (V2X) technologies, which enable EVs to not only draw power from the grid but also supply stored electricity back to it. By doing so, these EVs can help reduce energy demand during peak periods, lower energy bills, and decrease reliance on new grid infrastructure. The program includes four municipal projects, five school districts, and 30 residences, collectively expected to deliver over one megawatt of power back to the grid during demand response events—enough to power approximately 300 average American homes for an hour. Bidirectional charging technology leverages the large battery packs of EVs as mobile energy storage assets, allowing them to function as "virtual power plants" (VPPs) when aggregated. This capability can enhance grid

A recent study by researchers from the University of Michigan and Ford Motor Company reveals that electric vehicle-to-home (V2H) energy supply can reduce EV charging costs by up to 90%, potentially saving homeowners between $2,400 and $5,600 over the vehicle’s lifetime. V2H utilizes bidirectional charging technology, allowing EV batteries to power homes much like a generator but without burning fossil fuels. This system enables homeowners to purchase electricity when it is cheap and clean—such as during peak solar power production—and store it in their vehicle’s battery for later use, thereby cutting both energy costs and greenhouse gas emissions from the building sector. The study, which analyzed a mid-sized SUV across 432 U.S. regions with varying climate and grid conditions, found that V2H could reduce a homeowner’s lifecycle greenhouse gas emissions by 70 to 250 percent, equivalent to offsetting 24 to 57 tons of CO2 or 80 to 190 one-way flights between New York and

Polestar has introduced a new bidirectional charging feature for its Polestar 3 electric SUV in the US, starting with California. Through a partnership with home energy company dcbel and its Ara home energy system, the Polestar 3 can now supply power back to a home during outages or periods of high electricity prices. This system leverages the SUV’s 400-volt architecture to provide up to 10 days of emergency backup power, potentially cutting annual charging costs by as much as $1,300. California residents can also benefit from incentives to offset hardware and installation costs. This launch marks Polestar’s first bidirectional charging offer and aligns with a broader industry trend, as other automakers like Ford, GM, Volkswagen, Hyundai, and Tesla have introduced similar vehicle-to-home capabilities recently. Polestar plans to expand this feature to additional states and markets but has not provided a specific timeline. The capability is currently available on Polestar 3 models built on the 400-volt platform, with

The article from CleanTechnica highlights the emerging role of used electric vehicles (EVs) as valuable assets beyond personal transportation, particularly through bidirectional charging technology. While used EVs have traditionally attracted buyers due to their affordability stemming from rapid depreciation, recent studies indicate that depreciation rates are slowing, especially for models with longer battery ranges like Tesla. Additionally, concerns about battery longevity have diminished as evidence shows EV batteries often last much longer than initially expected, enhancing the appeal of used EVs. A key development is the increasing availability of bidirectional charging in used EVs, allowing these vehicles to not only draw power but also supply electricity back to homes, worksites, or the grid. This capability transforms used EVs into mobile energy resources that can support local grid stability, emergency power needs, and renewable energy integration. The article cites a pilot microgrid project at Redwood Coast Airport in California, where two used Nissan Leafs equipped with bidirectional charging help manage energy flow, reduce costs, and provide backup power during

At the IAA Mobility 2025 auto show in Munich, Volkswagen made several significant announcements emphasizing innovation in bidirectional charging, artificial intelligence, and semiconductor procurement. Central to Volkswagen's strategy is a new procurement model developed in partnership with Rivian and Volkswagen Group Technologies, covering over 50 semiconductor categories including microcontrollers and power transistors. This initiative aims to streamline semiconductor sourcing, reduce costs, and ensure supply chain resilience, reflecting Volkswagen’s ambition to become a global leader in automotive technology. The company also hosted the 4th Semiconductor Summit, bringing together key industry players to strengthen collaboration between automotive and semiconductor sectors. Volkswagen subsidiary Elli introduced a pilot project for bidirectional charging in private homes, featuring a legally compliant 11 kW wallbox that connects electric vehicles with home solar systems through a modular software platform. This technology can potentially reduce charging costs by up to 75% and supports energy independence. Elli is recruiting participants in Germany for this pilot and plans to integrate EV battery storage into a virtual power

Honda has launched the N-One e, its first electric version of the popular kei car, targeting Japan’s competitive kei EV market. The N-One e features a 29.3 kWh underfloor battery delivering an impressive 183 miles (WLTP) of range, surpassing rivals like the Nissan Sakura and competing with slightly larger city EVs such as the BYD Seagull and Renault 5 E-Tech. Pricing starts around $18,300, rising to about $22,000 for higher trims. Despite the battery addition, Honda maintains cabin space by placing the battery under the floor and repositioning the steering wheel closer to the driver, ensuring comfort and practicality remain strong selling points. The N-One e offers flexible charging options, including a 6 kW onboard AC charger for a full charge in about 4.5 hours and 50 kW DC fast charging that reaches 80% battery in roughly 30 minutes. A standout feature is its bidirectional charging capability, allowing the

The article discusses the implementation and challenges of large-scale vehicle-to-grid (V2G) systems, focusing on recent developments in Utrecht, Netherlands, and plans in Sweden. V2G technology enables electric vehicles (EVs) to both draw electricity from and feed electricity back into the grid, effectively turning EV batteries into distributed energy storage. This system can help balance renewable energy supply fluctuations without utilities needing to install dedicated grid-scale batteries, while EV owners receive compensation. However, managing V2G is complex due to the need for coordination among diverse stakeholders—drivers, renewable energy suppliers, charging networks, and utilities—and the variability in EV models, battery management systems, and renewable energy availability. Utrecht has become Europe’s first city to implement a large-scale V2G system, called “Utrecht Energized,” through a collaboration involving Renault Group, We Drive Solar, and the carsharing service MyWheels. The initiative has installed 50 bidirectional chargers and integrated 50 Renault 5 E-Tech
