With the increase of electric products in life and the prevalence of new energy vehicles, the demand for energy storage products is also increasing day by day, especially for large -capacity energy storage products.The increase in capacity also requires the cooperation of fast charge technology. At this time, a good fast -charging chip is very important.
At the same time, with the development of energy storage technology, higher requirements have been put forward on energy conversion efficiency. Fast charging chips need to have higher power conversion efficiency to reduce energy loss in the fast charging process, reduce the fever and improve the energy efficiency of the overall system system.EssenceAnd fast charge needs to support higher charging power, such as200W or even higher power level fast charge technology.
The fast charging chip should also have a dynamic identification battery status, and the ability to adjust the charging voltage and current in real time to ensure that it can accurately control the charging rate when approaching the full charge to avoid the security risks brought by overcharge.At the same time, a built -in multiple security protection mechanism is built to prevent the battery life of the battery overheating, overvoltage or overcurrent due to rapid charging, and extend the battery life.
Because energy storage equipment often needs to process the input and output of different voltage levels, the fast charging chip needs to have a wide range of voltage adaptability and compatible with a variety of charging protocols to flexibly apply it to different application scenarios and equipment.There is also a miniaturization trend of energy storage equipment. The design of the fast -charging chip also requires more compact, integrated more functions, and minimizes the packaging size as much as possible to adapt to the space limitations of portable energy storage equipment.
In addition, for the current development trend of energy storage products, it also requires higher stability and reliability for fast charging chips. At the same time, while having high performance, it is necessary to maintain a reasonable price level to facilitate large -scale commercialization applications.EssenceIt is best to support a variety of fast charge protocols and integrate multiple functions.
Many companies at home and abroad have launched representative products in the field of energy storage and fast charge chips at home and abroad. These chips usually have high integration, supporting a variety of fast charge protocols, high -precision voltage and high -precision voltage and high accuracy.The current control, high efficiency, and built -in protection functions are suitable for portable energy storage power supply, fast charger and other products.
Foreign representative enterprise RuTi, ADI, Microchip, Infineon, ST, etc. have all launched a number of related fast -charged chip products, such as TI's BQ25619 supporting a variety of fast charge protocols, including USB, PD, Qualcomm, IC, etc.It has high -precision current and voltage control, as well as thermal management and battery protection functions.
Similar to likeADI's ADP2320, Microchip's MCP73831, Infineon's XDPS2200, and ST's STUSB4500.There are many common characteristics in design, such as supporting a variety of fast charging protocols to meet different charging needs and equipment; with high integration design, reducing the number of external components, reducing system cost and space occupation;The voltage and current control of accuracy optimize the charging efficiency and battery life; basically built -in protective functions, such as overcurrent, overvoltage, excessive mild short circuit protection to ensure the safety of the charging process.
There are also many mature solutions in the domestic energy storage fast charging chip, such as Nanxin semiconductorSC9711, supports 40V input resistance, 6A output current, and power output above 65W.Support PD3.0 and PPS fast charge protocols, Huawei FCP/SCP, Samsung AFC fast charging, Apple 2.4A charging.Support two chips to communicate with each other without MCU control, achieve maximum power output of the single -port, and automatic power distribution power when the double -port outputs at the same time.Xinhai Technology's CSU3AF10 series supports fast charging protocols such as USB PD3.0 and UFCS. At the same time, it is compatible with Huawei SCP, FCP, Samsung AFC, VOOC, Apple2.4 and other mainstream fast charging private protocols., Integrate 32K*16-bit Flash memory and 2K SRAM, support the two independent Type-C ports, at the same time integrate ESD8KV protection, Latchup 400 protection, and security strategies provided for Flash memory.
And like Ying JixinIP2726, supports Type-C DFP, PD2.0, PD3.0, PPS, QC4+, QC3.0, QC2.0, FCP, AFC, SCP, MTK PE+, Apple2.4A, BC1.2, and Samsung 2A.It has a high -integratedness and rich function, and only very few peripheral devices are required when applying.
Qin Heng Micro ElectronicsCH235S is a Type-C single-port fast charge protocol chip, supporting Type-C fast charge protocols such as PD3.0/2.0, PPS, and Type-A fast charging protocols such as BC1.2.Integrated VBUS detection and discharge function, providing underwriting, overcurrent, and over -temperature protection functions.
Of course, here is only the statistics of some domestic fast charge chips, and many excellent fast -charging products have not been included in it because of space limitations.It can be seen from the above products that these fast charging chips are widely used in products such as chargers, mobile power, car charging and other products, and provide efficient, flexible and safe fast charging solutions.
And a good energy storage fast charge chip design is a complicated process. It needs to combine the latest technical standards, market demand, and security and performance requirements to continuously innovate and improveThe needs of the plan.
summary
Fast charging chips are usually used in new energy vehicles, mobile power, light energy storage and other fields. They also need to meet specific industry standards and safety specifications to ensure the reliability of the equipment and the safety of users.When choosing a fast charging chip, you should also pay attention to the market application prospects of the chip, the space increase space, andBMS compatibility and other factors.With the continuous progress of technology and the growth of market demand, the development and application of fast -charge chips will continue to promote the development of energy storage technology.
