The electronics industry in the first half of this year is not very good, but the Munich Shanghai Electronics Show on July 8 is extremely hot, including more than 1670 exhibitors, more than 75,400 professional visitors to the scene. A number of companies focused on new energy vehicles, photovoltaic, energy storage, robotics, third-generation semiconductors and other cutting-edge hot areas. TI brings the most advanced BMS chip in the field of energy storage, and Infineon brings a new generation of silicon carbide technology demonstration. At the chip booths for automobiles, energy storage and robotics, the flow of people continued to feel the pace of economic recovery in the electronics industry.
TI focuses on how to turn clean energy into electricity. We start from energy generation, energy transmission, energy storage, and finally the use of energy by users, and how to improve efficiency, reliability and safety in the whole process of electricity distribution and distribution. This is the consideration of Texas Instruments in the systematic design of new energy.
Mr. Tan, TI Systems Manager, said, "We are experiencing an energy transformation that will completely change how we access, store and use energy. The transformation of the energy industry cannot be achieved without semiconductor technology, whether it is in photovoltaic, energy storage, or charging piles, semiconductor technology plays a pivotal role."
At the TI exhibition, we saw a gallium nitride 1.6KW bidirectional micro inverter with a C2000 device, a reference design that supports four identical channels and is controlled using a C2000 MCU. The design can be connected to photovoltaic (PV) panels or 48V battery energy storage systems (BESS), providing an efficient and flexible energy management solution. From battery charging and discharging to the final inverter, the efficiency of each stage can be achieved more than 98%, and TI's new products have achieved more than 99% at the level of MPPT and inverter. With a powerful master processor, the C2000 has a wide range of applications in the field of motor control, including accurate ADC sampling, powerful PWM control, ideal for power supply and motor control.
In addition to the bidirectional micro inverter, we also see TI launched a high-power composite inverter based on the whole house photovoltaic panel, this product is based on GaN 7.2KW series hybrid inverter, it can be charged from the grid to the battery, but also can realize the battery to the grid power supply, the whole process is connected to one end of the photovoltaic panel, one end of the battery, and one end of the grid. Thus, the energy of the entire photovoltaic panel, the capacity of the battery and the energy of the grid can be organically combined, and the lowest cost of household electricity can be created through real-time control.
Infineon introduces a new generation of silicon carbide technology, CoolSiCTM MOSFET Gen2 technology, which improves key MOSFET performance metrics such as energy and charge storage by 20% compared to the previous generation, significantly improving overall energy efficiency. Evaluation boards for 1200V CoolSiC MOSFETs, 2000V CoolSiC MOSFETs and gate drivers are on display. With its superior performance of high power density, this product can reduce losses by 50% and provide approximately 2% additional energy without increasing the battery size, which is particularly beneficial for high-performance, lightweight and compact energy storage solutions. It can be used in industrial energy storage.
The global optical storage system (PV-ES) market has witnessed rapid growth in recent years. The competition of optical storage market is accelerating, and the key to win is to improve the power density. How energy storage applications improve efficiency and power density has attracted much attention. Mr. Pan, Global Senior Vice President of Infineon, said: "We believe that semiconductor solutions are the key to achieving climate goals, and that Infineon can achieve a low carbon effect through semiconductor solutions. Wide bandgap semiconductors such as SiC and GaN, which are relatively small in size, high in density and high in efficiency, can play an optimal role in solving climate problems."
In the context of global carbon neutrality, energy transition has shown an irreversible trend worldwide. China plays an indispensable role in the global energy storage market. According to ESA statistics, the newly installed capacity of China's energy storage market in 2023 reached 51GWh, accounting for about 49% of the new installed capacity of the global energy storage market, and the next five years also show a rapid growth trend.
The final customer value of photovoltaic and energy storage systems is the "three high and one long", that is, high safety, high energy efficiency, high economy and long life. The battery management chip, processor chip, silicon carbide, gallium nitride and other semiconductor technology plays an important role in the energy storage BMS, the Munich Shanghai Electronics Show, Chinese and foreign chip manufacturers in the energy storage BMS chip, MCU chip, power device, isolation driver chip display, is to respond to the needs of energy storage end users, we hope to see more new products landing, Help China's photovoltaic and energy storage industry usher in new growth.
