At 14:30 p.m. on December 27, the 2023 iPhone15 series accessories new product launch conference was held live on the official account platform. In the first part of the press conference, Charginghead Network invited Mr. Wei Ming, Director of the USB Technology Department of the China Academy of Information and Communications Technology (CAICT) Terminal Laboratory, to share the content of "How Portable Electronic Products Respond to the Regulatory Requirements of the EU Unified Charging Interface".
Mr. Wei Ming is the head of the USB-IF Certification Laboratory (SAICT), and an authorized certified engineer for USB devices and USB cable connectors. He has been engaged in USB-IF compatibility testing and certification for 16 years, participated in the development of BC1.2, YDT1591, Type-C and PD and other test specifications and test tools, and has rich experience in USB product certification testing and debugging.
Common Charger is a specification introduced by the European Commission to provide a universal charger for smartphones. The specification requires smartphones sold in the EU to use the same charger interface to reduce waste and improve consumer convenience.
In October 2022, the European Parliament voted to make the USB-C interface a universal charging standard for small electronic devices by the end of 2024. Make USB-C the standard charging port for all electronic devices, including smartphones, tablets, cameras, headphones, portable speakers, and handheld video game consoles.
In September 2023, Apple released the iPhone 15 series with USB-C port in response to this EU regulation.
In addition to making USB-C the standard charging interface for Class 13 devices, the proposed amendments to the EU Radio Equipment Directive (RED) also propose that chargers should be "loosened" from the sale of equipment, and manufacturers will not be allowed to impose "unreasonable" restrictions on charging speeds.
"CE" is a safety certification mark, and the "CE" mark is a mandatory certification mark in the EU market, which is a mandatory requirement for products in EU law, similar to the 3C certification of the mainland.
The RED directive covers safety, electromagnetic compatibility EMC and radio spectrum requirements, covering all radio equipment operating at frequencies below 3000 GHz.
The European Union implements the Common charger requirements through the RED Amendment Directive, and the OJ of December 7, 2022 officially published the revised Directive (EU) 2022/2380 on universal chargers to supplement the specific implementation requirements of 3.3(a) of the RED Directive 2014/53/EU for the specific implementation of the universal charging interface. On June 27, 2023, the European Union approved the adoption of the 2022 version of the IEC 62680-1-2, -1-3 standard.
The RED Amendment Directive applies to the 13 types of wireless devices mentioned earlier, and the revised Directive will be mandatory in all EU member states from December 28, 2024, with the requirements for laptop devices becoming mandatory on April 28, 2026, and new devices entering the EU market after the mandatory date should meet the requirements of the Directive.
The revised RED directive also requires that all categories of devices should indicate the power range requirements for charging equipment in the user manual, and devices that support fast charging should identify PD fast charging "USB PDfast charging" and other supported fast charging protocols. The outer packaging of the device should indicate whether the charger is standard, the outer packaging and user manual should indicate the PD fast charging specifications, and the price tag should also be displayed next to the price tag at the time of sale, and the width of the logo should not be less than 7mm.
As can be seen from the diagram, Common Charger cites two USB-IF standards as supplementary requirements, which are embodied in the two standards (EN IEC 62680-1-3:2022) and (EN IEC 62680-1-2:2022) respectively, and finally restricts new devices entering the EU market through the RED directive.
EN IEC 62680-1-2 is a fast charging protocol based on the CC channel in a Type-C connector, which can negotiate and adjust the voltage, current, and charging direction for both the consumer and the power supply. The specification sets out detailed requirements for electrical requirements, physical layer, protocol layer, system policies, state machines, and power rules.
EN IEC 62680-1-3 mainly deals with three major topics: Type-C connectors, Type-C cables, and Type-C protocols (functions).
Mr. Wei Ming also answered three common questions, the first of which was the discrimination of RED/Common charger products.
The second question complements the requirements for chargers, USB-C cables, and 13 types of electronic devices to enter the EU market.
The third question mentions that the design of the TYPE-C female connector used must meet the requirements of EN IEC 62680-1-3 (USB-IF Type-C Cable and Connector Specification), i.e. the female connector can only be a 24-pin or 16-pin design, and other designs cannot be certified. There are also EMC Gnd loops to meet the requirements, choose one of three.
In addition, the current regulations are only for the device side, and the European Union is drafting a revised regulation on the EPS eco-design requirements for external power supplies based on the ErP regulations in line with the common charger initiative.
Since December 7, 2022, when the European Union issued a revised directive on Common Charger, the Thiel terminal laboratory launched a reference test scheme for the first time, and conducted in-depth discussions and studies with a number of manufacturers and EU NB institutions, and assisted many companies in conducting thorough verification.
At present, it has been accredited by CNAS for EN IEC 62680-1-2 and EN IEC 62680-1-3 testing capabilities, and cooperated with Timco, an American certification body, to issue the first EU RED Directive Common Charger certificate for domestic enterprises.
