AC Charging Connector Standard (SAE J1772 / NACS J3400) China uses GB/T 20234.2 for AC charging, defining a physically distinct 7-pin connector incompatible with SAE J1772 or NACS. The pin count, locking mechanism, and connector body shape all differ. A GB/T AC plug cannot mate with a J1772 or NACS socket.GB/T 20234.2-2015 (AC EV charging connector, China) US public AC Level 2 charging has historically required the SAE J1772 (Type 1) connector. From 2025 onward, NACS (SAE J3400, derived from Tesla's connector) has been adopted by most major OEMs and is increasingly deployed at public stations. Federal NEVI (National Electric Vehicle Infrastructure) program guidance requires CCS1-compatible ports at NEVI-funded stations; NACS is permitted as an additional or replacement interface. Both J1772 and NACS carry the same AC signal; a simple adapter allows cross-compatibility.SAE J1772 (AC EV Charging Coupler, Type 1)

23 CFR Part 680 (NEVI Formula Program, FHWA) — requires CCS1 ports at NEVI-funded stations
IEC 62196-2 Type 1 (international reference for J1772 profile)		 Hardware connector is physically incompatible. A Chinese EV with a GB/T AC inlet cannot charge at US public J1772 or NACS AC stations without a physical inlet change. The US market is transitioning from J1772 to NACS (SAE J3400); products entering the US must support at least one of these (or carry an OEM-supplied adapter). GB/T is not used or recognised at US public charging infrastructure.Non-compliant as-is. EVs exported from China to the US must be fitted with an SAE J1772 and/or NACS (SAE J3400) AC inlet.

DC Fast-Charging Connector Standard (CCS1 / NACS J3400) China uses GB/T 20234.3 for DC fast charging, defining a physically distinct 9-pin connector incompatible with CCS1 or NACS. The pin layout, communication protocol (CAN bus per GB/T 27930 vs. Power Line Communication per ISO 15118), and inlet shape all differ. A GB/T DC plug cannot mate with a CCS1 or NACS socket.GB/T 20234.3-2015 (DC EV charging connector, China)
GB/T 27930-2015 (DC charging communication protocol, China)		 US public DC fast-charging has been dominated by CCS Combo 1 (CCS1), combining the SAE J1772 AC coupler with two DC pins per IEC 62196-3 / SAE J1772 DC extension. Federal NEVI program (23 CFR Part 680 § 680.106) requires each DCFC port to have at least one permanently attached CCS Type 1 connector. In parallel, NACS (SAE J3400) — originally Tesla's proprietary connector — was published as an SAE standard in December 2023 and adopted by Ford, GM, Rivian, Honda, and others by 2024–2025, making it the emerging dominant DC standard. FHWA guidance permits NACS/J3400 adapters and connectors to be installed alongside mandatory CCS1 ports at NEVI-funded stations; NACS has NOT been formally approved as a replacement for CCS1 under 23 CFR Part 680. The FHWA August 2025 Interim Final Guidance did not alter this minimum standard — CCS1 remains required at all NEVI-funded DCFC stations as of June 2026.SAE J1772 (DC extension / CCS1 basis)

Chinese EVs with a GB/T DC inlet cannot fast-charge at US CCS1 or NACS stations. The US is in a transition period: CCS1 remains the federally mandated standard for NEVI-funded infrastructure while NACS (SAE J3400) is the dominant new-vehicle interface from 2025. Products must support CCS1 and/or NACS; GB/T DC inlet is not usable at US public DC fast-charge stations. Communication stack incompatibility (GB/T 27930 CAN vs. ISO 15118 PLC) further precludes any simple adapter solution.Non-compliant as-is. EVs exported from China to the US must be fitted with a CCS1 and/or NACS (SAE J3400) DC inlet to access US public DC fast-charging.

Electromagnetic Compatibility (EMC) — FCC Part 15 China uses GB 17625 series (conducted disturbance) and GB/T 17626 series (immunity) for EMC of electrical equipment, administered by SAMR. EV chargers exported from China to the US must be re-tested to FCC Part 15 limits, which differ from GB standards in frequency ranges, limits, and test methodology.GB 17625.1-2022 — Limits for harmonic current emissions

Energy Efficiency — ENERGY STAR for EVSE China does not have a direct equivalent to ENERGY STAR for EV chargers. The closest analogues are GB/T 29781 (EV charging station general requirements) and NB/T 33008 (charger technical requirements), which include some efficiency provisions. Note: as of March 1, 2025, EV charging equipment in China became subject to mandatory CCC certification (administered by CQC under CNCA rules, implementing GB/T 18487 and related standards) — this replaced the earlier voluntary-only regime. However, this mandatory CCC covers safety and functional requirements; there is still no Chinese certification equivalent to ENERGY STAR EVSE that specifically benchmarks standby/idle energy efficiency or loading-adjusted efficiency the way ENERGY STAR v1.2 does.GB/T 29781-2013 — Electric vehicle charging station general requirements
NB/T 33008.1-2018 — Electric vehicle off-board charger technical requirements
CCC mandatory certification (from March 1, 2025) under CQC-C2501-2025 implementing GB/T 18487 — covers safety and function; no ENERGY STAR-equivalent energy-efficiency benchmark		 ENERGY STAR EVSE (Version 1.2, effective 2023; Version 2.0 in draft as of early 2025) is a voluntary US EPA certification for Level 1 and Level 2 EV charging stations. It sets formula-based maximum power limits for No Vehicle Mode, Partial On Mode, and Idle Mode (e.g., No Vehicle Mode max = 4 W + network wake allowance + auxiliary feature allowances), weighted-average loading-adjusted efficiency requirements across 25%/50%/75%/100% load points, and requires third-party testing by an EPA-recognised lab. Although voluntary at the federal level, ENERGY STAR is often required or preferred by utility rebate programs, state incentives, and the federal NEVI Formula Program guidance for publicly funded charging infrastructure.ENERGY STAR Program Requirements for EVSE Version 1.2 (EPA)
Federal NEVI Formula Program Guidance (FHWA, Aug 2025 Interim Final Guidance) — ENERGY STAR is referenced as preferred/required by many state and utility programmes that administer NEVI sub-grants; not a direct mandate in 23 CFR Part 680 itself
California CEC Title 20 Appliance Efficiency Regulations (state-level, may apply separately)		 No CN certification substitutes for ENERGY STAR EVSE. To qualify for US utility rebates (e.g., PG&E, Con Edison) and NEVI-funded projects, manufacturers must independently test to ENERGY STAR EVSE Version 1.2 via a US EPA-recognised lab and list the product on the ENERGY STAR Certified Products database. CN efficiency standards and CQC marks are not recognised.Voluntary at federal level, but commercially critical. ENERGY STAR EVSE certification is effectively required to access US utility rebate programs and NEVI-funded public charging projects.

NRTL Listing (UL) + Authority Having Jurisdiction (AHJ) Permit In China, EV chargers require China Compulsory Certification (CCC) administered by CNCA through designated certification bodies. The main standards are GB/T 18487.1 (AC charging system requirements) and GB/T 20234 series (connector and interface standards). CCC covers both product safety testing and factory audits. Installation is governed by GB 50054 (low-voltage electrical installations) and GB 50966 (EV charging station design code), enforced by local construction authorities — somewhat analogous to AHJ, but operating under a more unified national code framework.GB/T 18487.1-2015 (AC EV charging system)

CCC certification (CNCA mandatory)		 EV chargers (Electric Vehicle Supply Equipment, EVSE) sold or installed in the United States must bear listing or certification from a Nationally Recognized Testing Laboratory (NRTL) recognized by OSHA under 29 CFR 1910.303. UL is the dominant NRTL for EVSE; the applicable product safety standard is UL 2594 (AC Level 2 EVSE) or UL 2202 (DC fast chargers). Beyond the product listing, installation of EVSE requires a permit from the Authority Having Jurisdiction (AHJ) — typically the local building or electrical department — which inspects installation against the National Electrical Code (NEC, NFPA 70), particularly Article 625. AHJ requirements vary by city, county, and state; there is no single national installation permit.29 CFR 1910.303 (OSHA NRTL recognition)

NFPA 70 / NEC Article 625 (Electric Vehicle Charging System)
NEC Article 230 / 240 (service and overcurrent protection, as applied by AHJ)		 CCC certification is not recognised in the United States and does not substitute for NRTL listing. A Chinese EVSE manufacturer must engage a US NRTL (e.g., UL, Intertek, CSA) to test and certify the product against UL 2594 or UL 2202 before it may be sold or installed in the US. In addition, each installation site requires a separate AHJ permit and inspection — a distributed, jurisdiction-by-jurisdiction process that has no direct analogue in China's more centralised code regime. The AHJ may impose additional local code amendments beyond the base NEC, which must be identified and addressed project by project.[INFORMATIONAL] NRTL listing (UL 2594 / UL 2202) is a hard market-access gate in the US — no NRTL mark, no lawful sale or installation. CCC does not transfer. Beyond the product mark, every installation requires a local AHJ permit; this distributed process is a recurring project cost absent from the Chinese regulatory model.

NEVI Program — Uptime, OCPP Networking, Open Payment, and Buy America (Federally Funded Public Chargers) China has no equivalent to NEVI's Buy America requirement or its open-protocol / open-payment mandates for publicly funded chargers. Chinese public charging infrastructure is predominantly deployed by state-owned enterprises (State Grid, Southern Grid) or large private operators (TELD, StarCharge) under national plans (e.g., the 14th Five-Year Plan EV targets). Communication protocols are based on GB/T 27930 (DC) and NB/T 33025 (operator platform), which are proprietary-compatible but not identical to OCPP. Payment is typically via operator apps or WeChat/Alipay; open contactless card payment is not mandated. There is no domestic content requirement analogous to Buy America for equipment procurement.GB/T 27930-2015 (DC charging communication between off-board charger and BMS)
NB/T 33025-2016 (EV charging network management system — platform communication)
New Energy Vehicle Industry Development Plan (2021–2035) — State Council, issued Nov 2, 2020 (Chinese: 新能源汽车产业发展规划（2020-2035年）)		 The National Electric Vehicle Infrastructure (NEVI) Formula Program (Infrastructure Investment and Jobs Act, Pub. L. 117-58, Sec. 11401) funds state EV charging networks along designated Alternative Fuel Corridors. FHWA's Aug 2025 Interim Final Guidance removed the prior federal 50-mile station-spacing mandate and simplified the process for states to certify that an Alternative Fuel Corridor is fully built out, giving states more flexibility in corridor planning. Charger-level NEVI requirements under 23 CFR Part 680 still apply to any charger installed with NEVI funds: (1) Hardware — minimum 4 DC fast charge (DCFC) ports per station, each capable of simultaneously delivering ≥150 kW; (2) Uptime — stations must maintain ≥97% uptime measured monthly; (3) OCPP 2.0.1 — chargers must use Open Charge Point Protocol 2.0.1 (or later) for communication with a Charging Station Management System (CSMS); (4) Open Payment — stations must accept credit/debit cards (ISO 8583 / EMV contactless) without requiring a network membership or app; (5) Buy America — iron, steel, manufactured products, and construction materials used in the project must be produced in the United States (per IIJA Sec. 70914 and FHWA waiver 88 FR 10619; EV chargers must have US final assembly from 23 March 2023, and chargers whose final assembly occurs on or after 1 July 2024 must have at least 55% domestic component cost); (6) Cybersecurity — chargers must conform to NIST Cybersecurity Framework and OCPP security profiles.Infrastructure Investment and Jobs Act (IIJA) Pub.

ISO 8583 / EMVCo contactless payment standards		 The Buy America requirement is the single largest barrier for Chinese EVSE manufacturers seeking NEVI-funded contracts. Current baseline under FHWA waiver 88 FR 10619: EV chargers must have final assembly in the United States from 23 March 2023; for chargers whose final assembly occurs on or after 1 July 2024, the cost of components manufactured in the United States must exceed 55% of the total component cost. No blanket waiver exists for Chinese-sourced EV charger components as of June 2026. The Aug 2025 Interim Final Guidance reduces one former siting constraint by removing the federal 50-mile station-spacing mandate and simplifying built-out corridor certification, but it does not remove the charger-level compliance gates; exporters must check each state's NEVI plan and site-selection rules instead of assuming a uniform federal spacing test. Beyond Buy America: (1) Chinese charger firmware typically uses GB/T 27930 or proprietary protocols — migration to OCPP 2.0.1 requires firmware redevelopment; (2) Open card payment terminals (EMV contactless) are not standard on Chinese-market DCFC units; (3) 97% monthly uptime SLA requires remote monitoring and rapid field-service infrastructure absent from a fresh market entrant; (4) NIST CSF cybersecurity requirements may conflict with current firmware architectures. Verify latest FHWA guidance and Buy America waiver status at fhwa.dot.gov before any procurement or grant application.[INFORMATIONAL] NEVI Buy America is a structural barrier, not a technical one: Chinese-manufactured EVSE hardware cannot qualify for NEVI-funded deployments without US-based final assembly (required from 23 March 2023) and, for chargers finally assembled on or after 1 July 2024, more than 55% US component cost. OCPP 2.0.1, open payment terminals, and 97% uptime SLA are operational requirements that must be designed in — they cannot be retrofitted at the permitting stage.

OCPP Networking and Utility/Site Interconnection Approval In China, EVSE grid connection is governed by the power grid company's own access rules (State Grid Q/GDW series standards for EV charging). Communication between chargers and the operator's cloud platform uses GB/T 27930 (DC charging) or proprietary protocols per the operator's CSMS. There is no open-protocol mandate equivalent to OCPP. Utility interconnection for EV stations is approved by the local grid company branch (similar in function to US utility interconnection review but under a single vertically integrated utility structure). Site-level permits are issued by local construction authorities under GB 50966.Q/GDW 1591 (State Grid EV charging equipment communication protocol — internal enterprise standard; current version may have been superseded by later Q/GDW editions; not publicly available in English)

GB 50966-2014 (EV charging station design code)
State Grid EV charging access management rules (internal grid company standards)		 Beyond product safety certification, US EVSE operators must navigate two further access layers: (1) Network/OCPP: Non-NEVI commercial charging networks increasingly require OCPP 1.6 or 2.0.1 compliance for charger-to-CSMS communication as a de facto market standard; several states (e.g., California under CPUC/CEC programmes) mandate OCPP for grant-funded installations even outside NEVI. (2) Utility and site approval: connecting EVSE to the grid typically requires notification to or approval from the local electric utility (load study, meter upgrade, transformer capacity review). For large DCFC installations (>100 kW), a formal utility interconnection study may be required. Site approvals (building permit, fire marshal sign-off) are AHJ-dependent. In California, the CEC (California Energy Commission) administers additional incentive programmes (e.g., CALeVIP 2.0 Fast Charge California Project, requiring OCPP 2.0.1 or later) with their own technical eligibility rules that change each funding cycle. Confirm the current CPUC decision and CEC CALeVIP round requirements at cpuc.ca.gov and energy.ca.gov before any programme application.OCPP 1.6 / 2.0.1 (Open Charge Point Protocol — Open Charge Alliance, de facto US network standard)

Entering US commercial networks (ChargePoint, Blink, EVgo, Electrify America, etc.) requires OCPP 1.6 or 2.0.1 compliance, which is a firmware and backend integration gap requiring non-trivial development effort. Separately, the fragmented US utility landscape means grid interconnection approval timelines and requirements vary enormously by utility and state — Chinese manufacturers with no US deployment history will face a learning curve on load study documentation, transformer upgrade cost allocation, and utility-specific metering requirements. State incentive programmes (e.g., CEC CALeVIP, NYSERDA) add further eligibility criteria that must be tracked per-programme.[INFORMATIONAL] OCPP 2.0.1 is the practical entry ticket for US commercial charging networks and any federally or state-funded deployment. California's CEC CALeVIP programme and CPUC IOU-funded programmes mandate OCPP 2.0.1 or later for funded installations; programme rules and decision numbers change each cycle — confirm current requirements at energy.ca.gov and cpuc.ca.gov before any application. The US utility interconnection process is fragmented and jurisdiction-specific — it is a project-management and timeline risk, not a certification gap, but must be resourced accordingly.

NEC Article 625 — EV Power Transfer System Installation China's primary standards for EV charging installation are GB/T 18487.1 (electric vehicle conductive charging system — general requirements; 2023 revision current) and GB 50966 (code for design of electric vehicle charging station). These cover general electrical safety and charging interface requirements but do not replicate the prescriptive installation rules, listed-equipment mandate, or AHJ permit-and-inspection process of NEC Article 625.

SAE J1772 / SAE J2894 — relevant interface standards referenced by UL 2202		 Chinese GB/T DC charging certifications are not accepted in the US. UL 2202 NRTL listing is required. Additionally, the Chinese GB DC connector is physically incompatible with US CCS (SAE J1772 combo) outlets, requiring hardware redesign for the US market. No mutual recognition exists between the NRTL program and Chinese CCC for DC EVSE.[INFORMATIONAL] Chinese DC fast charger manufacturers targeting the US market must obtain UL 2202 NRTL listing and redesign connectors for CCS compatibility. GB/T certification does not transfer. Engage an OSHA-recognized NRTL early in product development. Consult a qualified US compliance engineer. UL Standards & Engagement2026-06-11 · unverified
Personnel Protection Systems for EVSE (Shock Hazard Protection) Chinese EVSE standards address leakage protection and ground-fault detection within GB/T 18487.1 and related product standards, with requirements for residual current devices (RCDs). However, the specific protection levels, trip thresholds, and test methodologies differ from UL 2231. Chinese standards do not have a direct standalone equivalent to UL 2231.GB/T 18487.1-2015 — Sections covering leakage and ground-fault protection
GB 14050 — Specifications for Residual Current Operated Protective Devices (type A/B)		 US EVSE must incorporate personnel protection systems meeting UL 2231 (Standard for Personnel Protection Systems for EV Supply Circuits). UL 2231 covers ground fault protection, leakage current detection, and automatic de-energization to protect users from electric shock. NEC Article 625.22 mandates ground-fault circuit-interrupter (GFCI) or equivalent protection on all EVSE. These requirements apply to both AC (UL 2594) and DC (UL 2202) equipment.UL 2231 — Standard for Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits
NFPA 70 / NEC Article 625.22 — Ground-fault protection for EV equipment
29 CFR 1910.7 — OSHA NRTL Program		 UL 2231 personnel protection requirements must be demonstrated as part of UL 2594 or UL 2202 NRTL listing; Chinese RCD and leakage protection test data under GB/T are not accepted as equivalent. US NEC 625.22 mandates specific GFCI trip thresholds (typically 5 mA for personnel protection) that may differ from Chinese GB requirements. Manufacturers must validate protection circuitry against UL 2231 through an NRTL.[INFORMATIONAL] Personnel protection to UL 2231 is an integral part of US EVSE NRTL listing and cannot be waived or substituted with Chinese RCD test data. Manufacturers must test and document protection system performance through an OSHA-recognized NRTL as part of UL 2594 or UL 2202 certification. Consult a qualified US compliance engineer.
