Understanding the whole industry chain of PD 3.1

original Charging head network editorial department Charging head network

preface

In 1994, Intel and Microsoft initiated the International Organization for Standardization, or "USB-IF" for short. The organization developed a series of specifications and specifications for the Universal Serial Bus, which is the famous USB PD protocol. In addition, they also developed an adaptive standard interface, namely USB interface, on this specification.

Now, USB PD has become one of the most universal and influential public fast charging protocols in the world. The USB PD version 3.1 was updated on May 25, 2021 after several version changes. Although it has only been two years, with the widespread popularity of PD 3.1, a mature and perfect product ecosystem has been built. This article will focus on the technology, products and company of PD 3.1 to show readers its unique industry ecology.

Development history of USB PD protocol

USB Power Delivery (USB PD for short) is the USB charging standard technology released by USB-IF on July 5, 2012.

However, it is not the earliest charging standard of USB, The USB PD specification originated from the first charging protocol USB BC 1.2 introduced in 2010.

In the following ten years, both the number and technology of charging gears and the charging power have significantly improved. The following is the development history of USB PD protocol.

In May 2021, USB PD crosses 100W fast charging threshold, USB PD 3.1 is released. The protocol is divided into two parts. One is the Standard Power Range, SPR)， Another Extended Power Range, EPR)。 In fact, SPR is the main part of the USB PD 3.0 protocol of the previous version, which means that the maximum charging power of this part is still 100W; The additional EPR is based on this standard working range, which greatly expands the maximum power of fast charging to 240W.

At present, all kinds of fast charging products applied to USB PD 3.1 are developing rapidly, and a unique "PD 3.1 product ecology" has been constructed, which is the industry feature in the field of digital fast charging in recent years.

The product ecology of PD 3.1 originates from chip products that adapt to the PD 3.1 standard. Many chip manufacturers have developed chips that have passed the USB-IF certification (protocol chips E-Marker chip), and then the manufacturers of fast charging and 3C digital products put the chips on their own products and put them on the market. Within the product circle of PD 3.1, due to the unification of the technical standards of PD 3.1, each link of the industrial chain can perform its own duties and adapt to each other. Finally, a distinctive "PD 3.1 product ecology" will be formed

Next, the charging head network will unveil the "coat of PD 3.1 product ecology". We will first introduce the representative products of PD 3.1 in detail (laptops, chargers, charging cables, car chargers, and power packs), and then introduce the chips of PD 3.1 (protocol chips E-Marker chip) and manufacturers. Finally, get to know the well-known listed companies in the upstream of this product chain.

Summary of charging head network

This report deeply studies the technology and products of USB Power Delivery 3.1 (USB PD 3.1), hoping to present the readers with a more comprehensive and three-dimensional ecological outlook of PD 3.1, and summarizes the following points:

Market growth trend

USB PD 3.1 standard has become the mainstream choice of electronic device charging and connection. Although most electronic devices are still charged and connected with PD 3.0, the number of PD 3.1 products on the market is increasing significantly.

This is because the market demand for fast, efficient and multi-functional charging and connection solutions is increasing, and this trend will continue to drive the market growth of USB PD 3.1. It is expected that the market size will maintain steady growth in the next five years. Based on the current situation, it is hoped that more PD 3.1 car chargers and laptops will appear in the market in the future to enrich the market category.

technical progress

The USB PD 3.1 standard introduces higher power transmission capability and supports up to 240W of charging power. The significant increase in charging power means that the charging equipment will face higher voltage and current. This puts forward higher requirements for technology, and security performance will also face higher challenges.

However, for the moment, the power of charging products that support the PD 3.1 fast charging protocol is basically 140W, which is far from the upper limit of 240W. But this power is enough for most electronic devices. in any case, PD 3.1 fast charging technology provides more flexibility and performance for charging equipment. This technological progress is crucial for fast charging of laptops, smartphones, tablets and other mobile devices.

Compatibility and Interoperability

The popularity of USB PD 3.1 standard has prompted the development of more devices and accessories, but compatibility and interoperability are still an important issue. At present, The USB-IF Association has developed a unified standard, and all PD 3.1 products need to be certified by it, and then published on the official website. At present, the certification process is still being improved and standardized. The subsequent development of unified testing and certification standards will help to solve this problem and improve the user experience.

Sustainability and innovation

The high efficiency of the USB PD 3.1 standard helps reduce energy waste and carbon emissions. More and more companies and consumers incorporate sustainability into their purchase decisions, which makes USB PD 3.1 standard a powerful choice in the market with increasing environmental awareness.

to make a long story short, USB PD 3.1 standard still has great potential in the field of electronic device charging and connection. It is promoting the growth of electronic equipment market, rapid charging technology progress and sustainable energy development, but on the other hand, it still faces challenges. First, compatibility and interoperability issues need to be addressed, which requires close cooperation among all parties in the industry to develop standards and solve problems. Secondly, we need to increase R&D and investment in technology and continue to climb bravely to the power ceiling of PD 3.1. Finally, we hope to further enrich the categories of different product categories of PD3.1, such as notebook computers, car chargers, outdoor power supplies and other different product categories.
