The growth potential of the new energy storage market is huge

2023In the year, the scale of new energy storage installations in my country broke through for the first time20GW,yes2022Three times the same period of the year.Among them, the proportion of lithium -ion battery storage, approximately2023The total amount of global new energy storage has the total installed capacity of the world96.9%EssenceData from Sky Eye Inspection,2023There are many newly established energy storage enterprises in the year7.2Wanjia, yes2022Year1.8Times.The high -speed development of the energy storage market also provides market growth space for a variety of semiconductor technology, including wide controlband semiconductor technology.

Semiconductor separate devices and combination plans serving the energy storage of lithium -ion battery are the highlights of this year's Munich Shanghai Electronics Show.Energy storage electronic separation devices can be roughly divided into triode, diode,MOSFET、IGBT、IC(For example, charging managementICLithium battery protectionICWait) five types.And they will be used in battery management systems (BMS), Energy Storage Transformer (PCS) And Energy Management System (EMS) Production of three types of integrated systems.The head suppliers of the five categories of components are basically concentrated in Yingfei, Ansonami, Toshiba, Italian semiconductor, Texas Instrument, Enshiro, Fuji Electric, RomsDIODESAmong more than ten companies including Ruisa, Mitsubishi Electric, and Hitachi, the reporter saw most of the companies at this exhibition.

At the Munich Electronics Exhibition, the reporter learned that many component companies including Yingfei, Texas instruments, and semiconductors of Italian and Fa -Fa, basically have a piece for one piece for energy storagePCBThe board provides the supply capacity of almost all components, but most of the component companies do not directly provide customers with solutions. Instead, they provide a reference design for them, that is, the component combination solution reference sample is provided to help customers understand the company's products using the company's productsWhat functions can be achieved.

according toCNESAThe prediction of the scale of China's energy storage market, in conservative scenes, estimates2028The cumulative installation scale of the new year -on -year energy storage will reach168.7GW，2024-2028Compound annual growth rate (CAGR)for37.4%EssenceIn the ideal scenario, expected2028The cumulative installation scale of the new year -on -year energy storage will reach220.9GW，2024-2028Compound annual growth rate (CAGR)for45.0%EssenceJudging from the reporter's interviewing component companies in the Munich Electronics Show, various companies have felt a strong downstream demand, and have launched components and reference designs suitable for energy storage scenarios.

Energy Storage Electronics Gathering Munich Electronics Exhibition

This Munich Electronics Exhibition has attracted a lot of energy storage electronics related companies to participate in the exhibition.Among them, there are both old electronic component companies and new forces in the domestic wide -band semiconductor.

Texas instruments exhibited a number of reference designs for home photovoltaic energy storage scenarios.Among them, based onGaNof7.2kWReference design of a group string hybrid inverter (TIDA-010938),support7.2kWThe rated power from the string to the battery storage system, which can be configuredAC/DCThe converter can handle3.6kWSingle -phase grid connection.This design has two times the power density improvement, making the solar inverter lighter and easier to install; and the total loss(<2%)Low, it is convenient to use more sunlight to make the battery energy storage more efficient; because the passive and radiator reduces the overall size, it can help reduce the total manufacturing area.

Expanding is the primary task of component manufacturers

Components used for energy storage scenarios, compared with other application scenarios, have a common requirement: higher reliability.This is because of the bigMost of the electronic components used for energy storage work outdoors, among which there are many areas with low winter temperatures in the northwest of my country. This requires these componentsGuarantee continuous and stable work under extremely high or extremely low.And many energy storage devices exist as infrastructure, so the requirements of such devices are also higher than component products for other application scenarios.

At present, the new energy storage industry is in the period of rapid growth, the overall market shape of the market has not been shaped, the system integrates many participation enterprises, and the integration enterprises and their understanding of the products are not the same.There are many personalized requirements.At the site of the Munich Exhibition, almost all engineers believed that when they answered future product development direction, they believed that they need to continue to expand product types to meet the increasingly diverse needs of users.

In an interview with the reporter of the China Electronics News, Yingfei Applied Engineer said that the specifications of the customer's converter have changed rapidly. Driven by the new technology trend of batteries and other components, component products are also rapidly iterating, and there are more iterations in the iteration directionThere are different.For exampleIn terms of heat dissipation, the system is changing from wind cold to water. In terms of power, from small power to high power, DC voltage also has from1500Vimprove to2000VPropensity.ButIn other words, the number of products under the same category that the company can supply is gradually increasing, and gradually expands into a more comprehensive product cluster.Dong Jie said.

In an interview with the China Electronics News reporter, Texas Instrument China Technical Support Director said that in the field of energy storage, battery management is the core application.Battery management system (BMS) Real -time and accurate data collection of the voltage, current and temperature of each battery cell is needed.These data are for evaluating the battery cell SOC(Charging status) and SOH(Health) is important.Data communication in the energy storage system is usually adopted CAN or LIN Wait for mature protocols.The collected data will be transmitted to MCUFor further calculation and status judgment to achieve efficient management of the entire energy storage system.
