en.Wedoany.com Reported - BYD Semiconductor's BMS AFE (Battery Management Analog Front-End) chip cumulative shipments have exceeded 100 million units, as recently disclosed by the company. Since the first automotive-grade model BF8915A-1 entered mass production and vehicle installation in 2021, this series has ranked first in both shipments and vehicle installations among domestically produced automotive-grade BMS AFE chips in China.

These 100 million chips have been widely used in electric vehicles and energy storage systems and other equipment. According to the company's statistics, its BMS AFE chips have monitored over 1.6 billion battery cells cumulatively, maintaining a record of zero major quality incidents over five years of application. In terms of technical specifications, the chip's sampling error does not exceed ±3 mV across the full temperature range, with measurement time for all channels controlled within 1 millisecond; the product complies with the ISO 26262 functional safety standard and has passed AEC-Q100 Grade 1 automotive certification, enabling stable operation in extreme automotive environments ranging from -40°C to 125°C. A single chip can support monitoring of 8 to 18 battery cells in series, is compatible with various electrochemical systems such as lithium-ion, lithium iron phosphate, and sodium-ion batteries, with a maximum balancing current of up to 300 mA, supporting both passive and active balancing modes. Through a daisy-chain cascade architecture, the chip can simultaneously detect hundreds of series-connected cells, flexibly adapting to battery packs of different sizes.

BYD Semiconductor has also outlined its BMS product matrix, including AFE analog front-ends and complete system solutions, providing comprehensive support from chips to system-level applications.
