EV Charging, Reservation, & Payments

Led by the DRIVES Program, this pilot demonstrated the potential use of MOBI’s Web3 Infrastructure in multiparty applications for electric vehicle charging, reservation, and payments, as well as battery data tracking.

About Our Interoperability Pilots

Alongside our global community, we’ve demonstrated several potential use cases for Citopia and Integrated Trust Network (ITN) services through various pilot projects. Citopia and the ITN services are business-to-business (B2B) only. Together, Citopia and the ITN provide the necessary infrastructure for node operators to build out secure, seamless, globally compliant web services and applications. MOBI membership is required to operate a node on Citopia and/or the ITN. Contact us to learn more about becoming a node operator

With electric vehicle (EV) sales skyrocketing in recent years, many EV owners are seeking integrated, user-friendly ways to manage and maintain their vehicles and interact with EV charging infrastructure while preserving data privacy for both vehicle and infrastructure owners. Today, integrated EV infrastructure solutions are generally unable to scale due to data siloing and the rising cost of trust. Solving this problem requires (1) a standardized framework for verifying claims & identities, and (2) a shared network and trust anchor for cross-industry coordination and data sharing.

To this end, MOBI and its members developed a pilot to demonstrate the potential use of MOBI’s Web3 infrastructureCitopia and the Integrated Trust Network (ITN) — in facilitating the creation of globally scalable, privacy-preserving solutions related to EV charging, reservation, and payments, in addition to EV battery data tracking. The pilot leveraged Citopia Self-Sovereign Digital Twins™ (SSDTs™) and World Wide Web Consortium (W3C) Verifiable Credentials (VCs) to simulate interactions between EV drivers, charging stations, and related service providers. The user journey involved EV drivers using Citopia to (1) search for charging stations along their route, make reservations, track charging progress, and pay; and (2) access their EV battery’s State of Health (SOH) and State of Charge (SOC) information. Please note that dummy SOC and SOH data was employed for the purposes of this pilot. In a real world implementation, this data would be provided by the battery and/or vehicle manufacturer.

The user journey involved EV drivers using Citopia to:
1. Search for and reserve charging stations
2. Track charging progress and pay
3. Access their EV battery’s State of Health (SOH) and State of Charge (SOC) data*
*NOTE: This pilot used dummy SOC and SOH data. In a real world implementation, this data would be provided by the battery and/or vehicle manufacturer.

What the Pilot Demonstrated

The pilot demonstrated the capacity for seamless booking, management, and payment for EV charging as well as user tracking of battery SOH and SOC via MOBI Trusted Trip VCs on Citopia, with trusted identity and assurance services provided by the ITN. The pilot successfully illustrated the respective capabilities of MOBI Trusted Trip VCs to verify the beginning and ending of charging trips and other VCs to enable agreements between users and service providers pertaining to booking, payment, etc.

All transactions executed via Citopia go through the SSDTs™ of ecosystem stakeholders by issuing VCs with embedded Decentralized Identifiers (DIDs) for future verification. The EV Charging, Reservation, and Payment pilot showed that these transactions can be executed while preserving data privacy, such that EV owners maintain control over their Personally Identifiable Information (PII), trip, and battery data, and service providers maintain control over their business data. All personal and competitive information is stored locally in the SSDT™ and remains under the owner’s control, inaccessible to Citopia and other third parties.

Though the trip planning segment in this demo only focuses on searching for in-route charging points, Citopia permits service providers to integrate countless applications using open APIs, including applications for Road Usage Charging, EV Credits/Rewards, and Usage-Based Insurance. The Citopia marketplace is designed to enable direct connections between providers and users during trip planning, reservations, and payment, eliminating the need for costly one-off integrations through centralized platforms.

Our Innovative Solution

Currently, digital transactions rely on identities issued by centralized platforms to prove their credentials. However, in addition to being vulnerable to fraud, identity theft, and data leaks, centralized approaches to identity management fail to address the trust problems created by the rise of decentralized services, IOT, and Generative AI. As digitization advances, it will become increasingly challenging — and costly — to verify data authenticity, secure digital perimeters, and ensure cross-border regulation compliance. This is critical in pay-as-you-go use cases, where scalability hinges on the ability to safely and accurately capture data even as vehicles traverse jurisdictional lines.

Overcoming these challenges calls for a new solution. The White House’s Federal Zero Trust Strategy (2022) underscores this need by directing federal agencies to adopt a Zero Trust framework by the end of FY 2024. Zero Trust requires every entity to authenticate and validate every other entity for every single digital transaction at all times. Since this is not possible through Web2/centralized means, we must leverage Web3 technologies and principles to automate emissions tracking using Citopia Self-Sovereign Digital Twins™ (SSDTs™).

  • Zero Trust Authentication: Cross-industry interoperability requires claims and identities to be verified for each transaction to ensure maximum security. Read the Federal Zero Trust Strategy

  • Infosec & Selective Disclosure: Participants must be able to selectively disclose information for transactions at the edge. Verification must be done at the moment of transaction to eliminate the need for PII storage.

  • Scalability and Extensibility: Cross-industry interoperability requires a shared standards-based framework to enable the creation of globally scalable multiparty applications.

  • Data Privacy Compliance: Cross-industry interoperability requires (1) compliance with existing global data privacy regulations and (2) the flexibility to comply with future directives.

  • Global Standards: Cross-industry interoperability requires a standardized system for frictionless data exchange and collaboration while allowing stakeholders to retain their legacy systems.

  • Decentralization: Cross-industry interoperability requires a community-owned and -operated infrastructure to (1) prevent monopolization and (2) enable consensus-based trust.

What are SSDTs™?

SSDTs™ are portable digital twins that can automatically authenticate identity and selectively disclose pertinent data for Web3 transactions at the edge. SSDTs™ combine standards from W3C, MOBI, IEEE, ISO, SAE, and others with Zero-Knowledge cryptography to offer the data privacy and autonomy needed to engage in secure, tamper-evident transactions across the connected ecosystem. SSDTs™ enable cross-industry interoperability and business automation through:

  • Enabling seamless verification and validation of identities and transactions

  • Empowering the creation of regulation-compliant data privacy solutions

  • Providing the ability to obtain and monetize data at the moment of transaction without the need to open up databases / store data

  • Serving as platform-agnostic, legacy system compatible “universal translators,” eliminating the need to build new infrastructure / APIs
