What Charin does

CharIN (legally Charging Interface Initiative e. V.) is a Berlin-registered, German non-profit association (eingetragener Verein) founded in 2015 to develop and promote global interoperability standards for electric vehicle charging. It is the leading cross-industry convener in the EV charging standards ecosystem, with approximately 285-300+ member organizations spanning automotive OEMs, commercial vehicle manufacturers, EVSE hardware makers, component suppliers, energy providers, and grid operators. Its core technology portfolio centers on three charging standards — Combined Charging System (CCS) for passenger vehicles, Megawatt Charging System (MCS) for heavy-duty trucks, buses, marine vessels, and mining equipment, and the North American Charging System (NACS / SAE J3400) — together with the ISO 15118 communication protocol that underpins Plug & Charge and Vehicle-to-Grid (V2G) functionality. Supporting assets include a CharIN Conformance Testing framework, the IEC TS 63379 specification for MCS (published February 2026), a global CCS Charging Map covering 125,000+ charging points, and a network of Testivals for hands-on interoperability validation across Europe, North America, and Asia.

CharIN's business model is non-profit membership-based, with revenue derived from tiered membership dues (Core, Regular, and Startup categories governed by a published Dues Schedule) and professional services delivered through CharIN Academy GmbH, a wholly-owned subsidiary providing ISO 15118 training, Testival organization, trade fairs, and conferences. The organization operates with regional offices in Berlin (HQ), Bangkok, Doha, Hong Kong, Sacramento, Detroit, São Paulo, and Australia/New Zealand. Distribution is community-led: members are recruited across the e-mobility value chain, onboarded through a board-reviewed application process, and engaged via working groups, focus groups, task forces (NACI, MCS, Marine), Testival events, CharIN Tuesday webinars, and the CharIN App. The organization holds no external investors, has no parent company, and is governed by a board chaired by Claas Bracklo with operational leadership including CTO Michael Keller and Executive Director North America Erika Myers.

CharIN's strategic positioning sits at the intersection of standards development, regulatory advocacy, and ecosystem coordination. Its standards are embedded in binding frameworks including the EU Alternative Fuels Infrastructure Regulation (AFIR), IEC specifications, and SAE International outputs, and the organization actively engages in regulatory consultations across the European Commission, U.S. California Energy Commission, Brazil's ABNT, and other national bodies. CharIN's primary defensibility rests on its regulatory moat, network effects from member scale, and institutional lock-in through conformance testing and certification workflows rather than on proprietary technology or capital-intensive assets.

Scale indicators7 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• ABB E-mobility: ABB E-mobility is one of the world's largest manufacturers of DC fast chargers and a CharIN Core member implementing CCS and MCS products. As a major hardware incumbent, ABB E-mobility is both a CharIN member whose success depends on CharIN's standards and a broader competitor-shaped participant in the EV charging infrastructure market.
• Tesla: Tesla developed the NACS connector that CharIN's NACI Task Force absorbed and helped re-standardize into SAE J3400, and Tesla operates the largest proprietary DC fast-charging network in North America. Tesla is both a forcing function that pushed CharIN to broaden scope and an ecosystem participant whose charging network and connector choice materially shape CharIN's roadmap.
• International Organization for Standardization (ISO): ISO publishes ISO 15118, the underlying vehicle-to-charger communication standard on which CharIN's Plug & Charge and V2G work is built. As a far larger and more general SDO spanning every industry, ISO sits above CharIN's charging-specific scope and is a critical upstream dependency for CharIN's product.
• SAE International: SAE International is a large, established standards development organization focused on mobility engineering (aerospace, automotive, commercial vehicle). SAE officially standardized NACS into SAE J3400 in June 2023 — work in which CharIN members directly participated via the NACI Task Force — making SAE both a publishing partner and a broader standards umbrella that competes for mindshare in EV charging specs.
• ChargePoint: ChargePoint is one of the largest North American EVSE network operators and a CharIN member. As a major deployer of CCS/NACS hardware, ChargePoint is both a downstream customer whose products must implement CharIN's standards and a broader EV charging incumbent with overlapping ecosystem influence.
• International Electrotechnical Commission (IEC): IEC is the global standards body that published IEC TS 63379 in February 2026, the technical specification for Megawatt Charging System (MCS) connectors and cable assemblies — work directly driven by CharIN's MCS Task Force. IEC sits one layer above CharIN in the formal international standards hierarchy and is a publishing partner and broader SDO umbrella.

Emerging players

• Hubject: Hubject is a Berlin-based e-mobility platform operator (spun out from major German utilities) that runs the Intercharge Network with access to 1,000,000+ charge points across 70+ countries and provides Plug & Charge ecosystem solutions. It is a CharIN Strategic Partner for Plug&Charge End-to-End Testing, occupying an adjacent interoperability niche (e-roaming and identity) that complements CharIN's physical-layer standards.
• Kempower: Kempower is a Finnish DC fast-charger manufacturer and an active participant in the MACBETH MCS project alongside CharIN, deploying MCS-compatible hardware for electric truck depots. As a fast-growing MCS charger specialist, Kempower sits at the leading edge of the heavy-duty standard CharIN is commercializing.

Direct peers

• Open Charge Alliance: Open Charge Alliance is the non-profit industry consortium that develops and maintains the Open Charge Point Protocol (OCPP), the dominant back-end communication standard between EV charging stations and network management systems. Like CharIN, it is a member-driven standards organization serving the EV charging ecosystem; the two complement each other (OCPP handles network communication, CharIN handles physical/communication between vehicle and station) and represent the two principal interoperability frameworks in EV charging.
• CHAdeMO Association: The CHAdeMO Association is the Japanese-led global industry association that developed and maintains the CHAdeMO DC fast-charging standard, the principal global rival to CharIN's Combined Charging System (CCS). It shares CharIN's exact business model — non-profit, membership-funded, focused on DC fast-charging interoperability — and competes for the same automaker and EVSE manufacturer mindshare.
