In the first half of 2023, Core Sea Technology (stock code: 688595), following the large-scale production of high-precision BMS single power saving meter products in 2022, once again launched CBMX58X serialization2-4节BMS管理芯片。CBMX58X系列包含CBM8580、CBM6580And other specifications of products,Can meet the high, medium and low end of all kinds of differentThe market for end applications需求。Among them, the CBM8580 is a single-chip fully integrated solution based on 2-4 serial lithium-ion or lithium polymer battery packs。The product provides capacity monitoring, protection and certification for 2, 3 and 4 series lithium battery packs，Take advantage of its integrated high-performance simulation peripherals，Measure the available capacity, voltage, current, temperature and other key parameters of lithium batteries，Maintain accurate data records，The information is reported to the system host controller through the communication interface。CBM8580With high-precision measurement, safety and reliability, high integration and easy development of product characteristics, key performance indicators to reach or even exceed the international mainstream products, is now entering the domestic brand customers mass production introduction stage, can be widely used in laptop computers, medical equipment, power tools, sweeping robots and other application scenarios。
Lithium core applications for notebook computers
As the most important productivity tool, notebook computers always strive to meet people's functional needs such as super-performance operations, high-frequency network transmission, and portable mobile office under the product form of smaller volume and lighter quality。Therefore, the comprehensive performance of safe, fast charge and discharge and long endurance of the pen battery presents a continuous technological innovation challenge。
In the northern ice and snow, the laptop is easy to suddenly shut down causing inconvenience, the reason is that the battery BMS system in the low temperature environment, due to inaccurate metering caused by the power jump, and the system is identified as low power caused by shutdown。Therefore, it can be seen that for the pen BMS, the most important function is still high precision measurement。Lithium battery with its small size, light weight, large capacity, fast charging and other advantages, become the best companion for the laptop。Compared with nickel-cadmium batteries, lead-acid batteries, lithium batteries because of greater energy density, fire and evenThe explosion risk factor is higher。At the same time, due to the requirements of various high-performance applications of notebook computers, the operating temperature of the battery is often above 45 ° C, and the technical requirements of thermal management are higher。Due to the need for a long standby time, the battery pack is basically composed of multiple parallel battery cells in series, and the voltage is increased in series and the capacity is increased in parallel。Therefore, compared with single BMS, multi-battery BMS need to collect and process more abundant data parameters, provide balanced power management and multiple security protection functions, so as to ensure the continuous operation and service life of the battery pack。
Advantages of CBM8580 laptop applications
With its own technology accumulation of nearly 20 years in the field of "analog signal chain +MCU", Core Sea technology cuts into the BMS track, fastQuickly realize the technical breakthrough of single segment to multi-segment products, and launch the new BMS CBM8580。
Core sea technology CBM8580 application block diagramFor laptop application scenarios,CBM8580With more robust product performance,With high precision, high safety, high integration, easy development and many other product advantages,Without changing the circuit design and connection mode, it can achieve the perfect compatibility replacement of similar mainstream products of overseas leading manufacturers.Help laptopPACK and device manufacturers simplify the process of replacing or upgrading the battery management system (BMS) to improve efficiency。High precision measurement:CBM8580Two-channel sampling CCADC and VADC with minimum 0.5mΩ sampling resistance, leading similar products of voltage and current sampling accuracy。In product measurement, CBM8580 based on different working current and voltage, the measurement accuracy error value is lower, and the measurement accuracy is more accurate.Can make the high current quickly charged like a fish in water,Fill it up, empty it, and so onManage the battery power and health status of end products。Security protection:CBM8580With perfect security measures, fromChip hardwareAnd softwareSafety protection, safety certification standards and technical support comprehensively improve chip safety performance,Software-based level 1 and level 2 safety protection against overvoltage, undervoltage, overcurrent, short-circuit current, overload and overheating。Rich resources:CBM8580In terms of peripheral support, built-in I2C, UART, SPI and other interfaces communicate with other devices, and control the temperature sensor and battery status indicatorSupport a variety of security encryption algorithms, support customers二次开发，Meet the individual needs of terminal products in a full range。Development ecology:CBMX58X SeriesIt has a complete product development ecology, provides high-precision battery SOX algorithm, meets the requirements of customers' firmware burning and upgrading, and is easy to learnVisual upper computer software program, to meet the end product of the minimalist development needs。To sum up,CBMX58X系列With its own high-precision measurement, safety protection, highly stable product characteristics, and throughEfficient production process and cost control, bringVery competitive price/performance ratio优势。
CBM85The launch of 80 reflects the technical advantages of Core Sea Technology in the digital-analog hybrid field of "ADC+MCU", is the strategic layout of the company's product serialization development in the field of BMS, and is also an important measure for the company to continue to improve the ecological construction of PC products。At present, the BMS series products of Core Sea Technology have been recognized by customers in terms of technical performance, safety and reliability, as well as more stable domestic supply chain products。其中，Single section product CBM8560Has achieved the first-line mobile phone brand manufacturers high-end mobile phone mass production of 10 million scale,Multisegment productCBM8580也Enter a number of domestic brand customers mass productionIn addition, the company's research and development of commercial energy storage and power battery vehicle gauge level BMS products is also progressing smoothly。Subsequently, Core Sea Technology will continue to improve in consumer electronics, computers and peripherals, industrial electronics, automotive electronics and other application fieldsBMSProduct development and service capabilities, committed to becoming a leading force in the field of domestic BMS and power management chips。Last year's Taipei Computer Show (COMPUTEX 2022), Core Sea technology launched EC, PD, USB Hub, HapticPAD and many other computer and peripheral peripheral application products and solutions。At the upcoming Taipei Computer show (COMPUTEX 2023), which opens on May 30, the CBM8580 is expected to make its global debut as a major exhibiting product。Relevant exhibition, please look forward to!If you need to consult CBM8580 for more product details and sample application, please send email to sales@hfzawed.com。We will provide you with sincere service。
