OCPP charging pile motherboard without 3C certification? Sales prohibited from August onward!

I. The Legal Boundaries of 3C Certification

Certification subject

• Complete machine charging pile: Classified under the "Electric Vehicle Power Supply Equipment" category, mandatory 3C certification is required starting August 1, 2024. Sales, import, and use without certification are prohibited;

• Charging pile mainboard: As a component, it is not included in the 3C catalog separately and theoretically does not require independent certification.

However, the motherboard is the core of the whole machine's certification

• The whole machine 3C testing covers the safety of the motherboard (dielectric strength, insulation, temperature rise), EMC (conduction, radiation), and functionality (CP detection, relay control, metering);

• Motherboard change = full re-certification: Replacing the motherboard model invalidates the 3C certificate, requiring resubmission for inspection.

II. The Truth Behind "Ban on Sales Starting August"

At the whole machine level

• Starting from August 1, 2024, power supply equipment without 3C certification will indeed be prohibited from sale;

• By April 2026, the policy had been in effect for nearly two years, making it a routine rather than a news story.

At the motherboard level

• As a component, the motherboard does not require independent 3C certification but must meet the following requirements:

• When purchasing from the whole machine factory, inspect the type test report of the motherboard supplier (non-3C, but technical verification);

• Motherboard design changes require the OEM to reapply for 3C certification, implicitly binding motherboard compliance.

Marketing Copy Deconstruction

• "OCPP motherboard not banned by 3C" is a misinterpretation of concepts:

• The prohibited items are 3C-free complete machines, not motherboards;

• However, if the motherboard does not comply → the entire machine cannot pass the 3C certification → the entire machine is prohibited from sale → the motherboard is effectively out of the market.

III. Practical Key Points for Mainboard Compliance

From the perspective of the entire machinery factory

When purchasing motherboards, the supplier is required to provide:

• Technical parameters (voltage, current, insulation level) consistent with the whole machine 3C report;

• Change Control Commitment: Mainboard Design Freeze, No Unauthorized Component or Topology Modifications;

• Type Test Report, Certifying Compliance with Basic Tests Such as GB/T 18487.1 and GB/T 34657.

• From the perspective of motherboard manufacturers

Although there is no independent 3C, it is required to:

Designed according to 3C standards (withstanding voltage 2.5kV, insulation resistance >10MΩ, temperature rise <60K);

• Coordinate with the OEM for inspection submission, providing BOM, schematics, and PCB layout;

• Establish quality consistency control to ensure batch production matches the inspected prototypes.

IV. One-sentence summary

R1: "Cooking the same old dish" must be translated as "repetition."  The claim that "OCPP charging pile mainboards are banned from sale without 3C certification" is a marketing scare tactic—mainboards themselves are not mandatorily 3C-certified, but non-compliant mainboards render the entire machine ineligible for 3C certification, effectively barring market entry. When purchasing, manufacturers verify type test reports and technical conformity. Mainboard producers design according to 3C standards and coordinate inspections, ensuring compliance through mutual accountability. Since August 2024, 3C certification for complete machines has been enforced. Discussing a "ban starting August" in April 2026 is merely rehearsing the same old argument.
