Energy-storage-PCB-market-embraces-a-broad-development-space-under-soaring-new-energy-trends

At the beginning of 2023, “new energy” appeared in many electronics industry trend forecast reports, showing its extremely high prosperity. Among them, the industry is particularly optimistic about the three major segments of wind power, energy storage, and new energy vehicles.

With the development of lithium battery technology and continuous breakthroughs in energy storage technology in recent years, the concept of energy storage has once again been focused in market. By the end of 2022, the installed capacity of new energy storage projects that have been put into operation across the country will reach 8.7 million kilowatts, and the average energy storage time will be about 2.1 hours, an increase of more than 110% compared to the end of 2021.

Automotive PCB industry: Maintain a high growth rate under the trend of new energy and electrification

Automotive-PCB-industry-Maintain-a-high-growth-rate-under-the-trend-of-new-energy-and-electrification

As the basic component that carries current signals, automotive PCB will usher in growth opportunities with the trend of electrification and intelligence of automobiles.

According to industry forecasts, the electric intelligence of automobiles will bring a three-fold increase in the PCB industry. At present, whether it is autonomous driving or smart cockpit, the current intelligence is at the stage of sufficient technical reserves, mining of application scenarios, and the eve of large-scale vehicles. The value of PCB is expected to rise to a higher level, and intelligence is expected to relay electrification to become the second driving force for the growth of the automotive PCB industry.

Energy storage: its rapid growth on market brings the PCB of BMS to increase

Since 2020, China has continuously determined the policy goals of carbon peaking and carbon neutrality, driving the growth of renewable energy installed capacity from top to bottom, and energy storage has also become a key development direction.

Based on the global energy storage lithium battery shipments, the energy storage PCB market space is estimated. It is estimated that the global energy storage battery PCB scale will reach 6.885 billion yuan by 2025, and the market size will reach 25.812 billion yuan in 2030. The CAGR will reach 30.25% from 2025 to 2030, and the market space is broad.

Energy storage becomes a new starting point and changes the power battery pattern

As a key link between power generation and electricity consumption, energy storage batteries are of great significance to the transformation of the energy structure in the future.

Reducing carbon emissions is the general trend. Changing the energy structure dominated by coal, oil and other traditional energy sources and developing new energy sources is the only way. From the current point of view, the development of the energy storage industry has become one of the main paths to promote the transformation of the energy structure and realize the transformation of the energy system.

-Current China’s lithium battery energy storage market development situation

It is predicted that after five years, China, the United States, and Europe will be the largest incremental markets, roughly evenly sharing about 80% of the global market share.

1.The industrial chain is relatively complete.

The new energy storage industry chain includes upstream raw materials and equipment, midstream energy storage systems and integration, and downstream power system energy storage applications.

Among them, upstream raw materials mainly include positive electrode materials, negative electrode materials, electrolytes, diaphragms, and structural parts; upstream integrated system equipment mainly includes coating machines, mixers, etc.

Midstream energy storage systems and integration generally include four major components: battery packs, battery management systems (BMS), energy management systems (EMS) and energy storage converters (PCS). Downstream application scenarios mainly include power system energy storage on the power generation side, grid side and user side.

In the application of energy storage, the crucial semiconductor devices are: digital control platform and high-power switching devices.

The digital control platform is the core of energy storage. In the energy storage system, the digital control platform needs to calculate the signals collected by the power loop in real time. The workload of the data is very large, and it needs to achieve a response speed comparable to that of the analog circuit. High demands are placed on the digital control platform. Power switching devices, such as MOSFETs used in bidirectional full-bridge DC-DC, and IGBTs used in DC-AC are the main factors that determine the quality and performance of energy storage systems.

2. All technologies are ongoing.

After ten years of technology research and development, demonstration applications and commercialization attempts, China’s energy storage industry is at the forefront of the world in terms of technology applications. This has also formed a relatively prominent industry feature – all technologies are running hand in hand, but there is a lack of a technology with all-round absolute advantages.

The technologies here include not only physical energy storage technologies such as pumped water storage, compressed air energy storage, flywheel energy storage, and supercapacitors, but also electrochemical energy storage technologies such as lithium batteries, lead-carbon batteries, flow batteries, and sodium-sulfur batteries. These technologies have their own advantages and disadvantages, and the scope of application is also quite different.

From the perspective of different advantages and disadvantages, technologies with large scale, long life, safety and fast response are more suitable for application on the power generation side and grid side, while technologies with low cost, good recyclability, safety and fast response are more suitable for application at the user side.

Whether it is on the user side including consumer electronics products, or the large-scale application on the power and grid side, lithium batteries are relatively advanced, and its technological progress is more difficult.
