Complete Guide for Huawei Super‑Charge Certification｜SCP and FCP Protocol Application Steps and Test Metrics

Obtaining Huawei SuperCharge certification acts as a prerequisite for third‑party manufacturers to produce officially recognised Huawei fast‑charging accessories. Lots of suppliers remain confused about differences between SCP, FCP and SuperCharge and fall into traps regarding USB‑IF PD preconditions. This article clarifies protocol logic, application workflows and detailed test criteria.

1. Relationship between SCP, SuperCharge and FCP

SCP stands for Super‑Charge Protocol, the underlying communication protocol while SuperCharge is Huawei’s commercial trademark. Passing SCP tests grants you official SuperCharge certification directly.

FCP refers to Huawei’s early low‑voltage fast‑charging standard with a maximum output of 18W (9V‑2A). SCP‑compliant chargers adapt to older FCP‑supported phones properly without dropping down to regular 5V charging. However legacy FCP adapters cannot achieve high‑power charging for SCP‑enabled smartphones.

Huawei never releases separate certificates for SuperCharge 1.0 or 2.0 versions. Updated dynamic temperature‑control schemes only mean revised SCP test specifications rather than independent certification versions.

  2. Pre‑Application Requirements to Correct Misconceptions

·USB‑IF PD3.0 certification is not a compulsory prerequisite: SCP is Huawei’s private fast‑charging protocol operating separately from USB‑IF PD standards. You only need USB‑IF approval if your charger supports both SCP and PD output. Pure SCP‑only adapters skip USB‑IF certification entirely.

·Choose charging ICs from Huawei’s recommended component list: If you select chips outside this list, you have to deliver hardware simulation reports and temperature‑protection analysis documents, extending review periods by two‑three weeks. Voltage and current precision is strictly controlled. The 20V‑5A high‑power mode allows a tolerance of ±100mV; non‑compliant accuracy will result in redesign.

Differentiate certification scenarios clearly:

·Original Huawei mobile phones do not need end‑device SCP certification; only chargers require approval to activate fast‑charging modes.

·Third‑party hardware like tablets and vehicle‑mounted chargers need separate end‑side SCP certification.

  3. Step‑by‑Step SuperCharge Application Process

·Register an enterprise account on the Huawei Developer Alliance platform. Starting in 2026, brand‑authorisation documents become mandatory for OEM‑branded products without which Huawei rejects applications outright.

·Submit technical documentation including circuit schematics, BOM lists and protocol implementation plans. Huawei’s engineering team returns revision feedback within one‑two weeks.

·Send 3‑5 sample units to Huawei‑authorised labs in Shenzhen or Shanghai. Expedited services cut test cycles by roughly 30% at an extra cost of 30‑50% of standard testing fees.

·After passing all tests, Huawei issues formal certificates valid for two years. Certified products can carry Super‑Charge logos complying strictly with Huawei’s trademark guidelines on colour, proportion and placement.

  4. Detailed Breakdown of SuperCharge Test Items

·Protocol handshake testing forms the strictest assessment item. Chargers and mobile phones must establish SCP connections with zero failures across 1,000 continuous handshake cycles. Even a single timeout or power‑drop leads to failure, contradicting online rumours allowing a 0.1% failure rate. Engineers also test automatic re‑connection after cable unplugging and signal interference.

·Temperature tests run under two environments: Under a standard 25℃ setting, charger surface temperatures cannot exceed 65℃ and battery temperatures stay below 45℃ after 30‑minute full‑charge cycles. At a high‑temperature environment of 40℃, the maximum shell temperature for adapters drops to 60℃. Products designed only based on 25℃ conditions will fail high‑temperature testing easily.

·Tiered safety‑protection response times apply: Short‑circuit protection activates within 20ms while over‑voltage, over‑current and over‑temperature protections trigger within 100ms. Labs also test abnormal conditions such as broken cables and loose ports.

·Two compliance paths for charging cables: Mass‑produced dedicated cables can get separate Huawei certification codes. Commercially available E‑Marker cables meeting Huawei’s internal resistance and voltage‑drop limits can be used without extra Huawei cable certification.

  5. Project Cycles, Costs and Market Compliance Rules

·Timeline: It normally takes two‑three months from application to certification if your design works well. Projects with repeated revisions may take four‑six months.

·Charges include initial lab‑testing fees and document‑review charges with no annual membership fees. Full SCP testing costs about 30,000‑80,000 RMB; 100W high‑power products cost roughly 40% higher than medium‑power versions. Renewal‑test expenses vary based on hardware‑modification levels with no fixed half‑price rule. Brand‑authorisation files and simulation reports do not incur extra reviewing costs.

·Certificate validity and change rules: If you replace charging ICs or transformers during the two‑year validity period, full re‑testing becomes compulsory. Software‑only parameter adjustments only require simplified filings, while shell changes do not affect certificate validity at all. Certified chargers trigger fast‑charging automatically for Huawei phones; unapproved adapters only deliver basic 5V charging.

·New 2026 test requirements: 80W and 100W SCP chargers need dynamic‑load‑jump tests and ‑10℃ low‑temperature charging assessments. Combo products with wireless‑charging plus wired‑SCP functions undergo extra temperature tests and foreign‑object‑detection checks for wireless‑charging modules.

·Market‑surveillance risks: Huawei purchases products marked with Super‑Charge logos from online marketplaces for random inspections. Items failing protocol and power‑output tests get taken down from e‑commerce platforms. Mass‑scale unlicensed trademark usage triggers Huawei’s intellectual‑property lawsuits and compensation claims beyond product removal.
