This blog post will discuss the opportunities specific to V2X and bi-directional converters. V2X, which stands for ‘vehicle to everything’, is the umbrella term for the car’s communication system, where information from sensors and other sources travels via high-bandwidth, low-latency, high-reliability links, paving the way to fully autonomous driving. There are several components of V2X, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and vehicle-to-network (V2N) communications. All these can be made possible through bi-directional converters.

Digital Opportunities in Electric Vehicles – EVIT



  • Nuvve – The Nuvve Powerport AC charging station delivers up to 100kW of power in a three-phase configuration and 19kW of power in single-phase configuration in a compact size package (wall mount or pedestal). It’s certified to UL safety standards, is the first-ever NRTL-certified AC V2G charger, and is ENERGY STAR certified. AC bidirectional chargers are ideal for AC EV charging and AC electric bus charging and have been used by Nuvve in projects both in Europe and in the USA. The Nuvve DC Heavy-Duty Charging Station (EVSE-HD60) is designed specifically for vehicle-to-grid (V2G) applications and is the ideal solution for the rapid, smart charging of heavy-duty fleet vehicles such as electric school buses. The EVSE-HD60 is fully controllable through Nuvve’s fleet management app and our V2G platform (GIVeTM) enables unidirectional charging of any vehicle or full, bidirectional V2G and vehicle-to-building (V2B) services when connected to a V2G-compatible vehicle. Using IoTecha’s ISO/IEC 15118 technology, which has already been deployed in thousands of chargers and has been successfully interoperability tested with most EV brands, users will benefit from an easy-to-use plug and play system.
  • Delta’s V2X Charger (Vehicle-to-Home & Vehicle-to-Grid) is a bi-directional charging system that converts energy between EV battery and AC supply, along with power backup and energy management features. It supports both smart charging functions to the EV and energy storage functions such as peak shaving, load shifting, PV self-consumption, and power backup via upper-level EMS. Delta’s V2X Charger can be coupled with an existing PV system via AC-link or DC-link architecture for different user scenarios and make the most out of the PV system with high-efficiency power conversion from PV to load and PV to EV battery.
  • Fiat Chrysler Automobiles (FCA) plant in Mirafiori, Turin on the first phase of a vehicle-to-grid (V2G) pilot project. The initiative is aimed at two-way interaction between FCA’s full electric vehicles (EVs) and the power grid. In addition to recharging cars, the project will use their batteries to provide grid-stabilization services. The V2G pilot is Cloud-based and the charge flow on either side can be monitored and controlled via proprietary software.
  • A part of the Hinduja Group, Gulf Oil International Ltd (Gulf), has entered an agreement to co-invest with the Clean Growth Fund (GCF) in Indra, provider of fast-growing electric vehicles (EV) and innovative charging and energy storage solutions. Indra Renewable Technologies Ltd produces a range of smart energy products, including its market-leading EV Smart Charger and a bi-directional ‘Vehicle to Grid’ (V2G) chargers for both residential and light commercial use.
  • The 40,000 square foot Alliance Center in Denver is installing a bidirectional electric vehicle charger and advanced software technology in the parking lot that serves the building; the software system will use energy stored in a Nissan Leaf battery to charge the building during peak demand times. The system will lead to energy cost savings and a reduction in the building’s carbon footprint, The Alliance Center says. The Alliance Center is working in conjunction with Fermata Energy on the project. Fermata’s V2B (vehicle to the building) system enables electric vehicle owners to make money while their cars are parked.
  • Nuvve Corporation, a leader in vehicle-to-grid (V2G) technology, and IoTecha Corp., a provider of electric vehicle (EV) smart charging technology, are joining forces to deploy and commercialize a bidirectional charging solution for electric vehicles with the Combined Charging Standard (CCS) plugs supporting the ISO/IEC15118 protocol. This approach allows automotive OEMs using the CCS plug for their vehicles to enable bidirectional energy flow on their vehicles when coupled with IoTecha and Nuvve technology. Future versions of the standard will be supported by over-the-air software updates.
  • The Ioniq 5 EV is rumored to come in the rear- and all-wheel-drive configurations, with power outputs of up to 310 hp. EV range is said to be 510 km in the WLTP cycle. The supposedly leaked dealer presentation also revealed DC fast charging of up to 232 kW, meaning an 80% state of charge can be reached in just 18 minutes. There’s also bi-directional charging with Vehicle to Load (V2L) support up to 3.5 kW, meaning the car’s battery can double up as a high-capacity external power bank, as demonstrated by Hyundai’s earlier “Camping” teasers. Those videos show the Ioniq as the perfect camping partner.
  • Boulder is testing a new project that will use a bidirectional electric vehicle charging system at the North Boulder Recreation Center to reduce the city’s energy load and lower utility costs. The novel charging technology allows power to be drawn from vehicles for use within the North Boulder Recreation Center during the day when demand is highest, and charges vehicles overnight.
  • ABB supplies its bi-directional charging technology to a Vehicle-To-Grid (V2G) partnership project. As part of a contract with France’s DREEV, a joint venture between Électricité de France (EDF) and Nuvve, which specializes in intelligent charging for EVs, ABB will supply its brand-new 11 kW bi-directional charging technology, specially designed for V2G. ABB’s solution integrated with DREEV software technology will enable EV drivers to export surplus power back to the grid. With the potential to generate up to 20€/EV/month, V2G thereby reduces the total cost of ownership and further boosts the adoption of EVs. Bi-directional chargers also help smooth the flow of uneven generation of electricity from renewable sources such as solar and wind. The charger will also collect data from the charger on the charge flow, the operational temperature of the vehicle and communicates with BMS, and upload these data to a cloud server.
