In today's era of pervasive smart devices, smartphones encounter electromagnetic interference over 30 times daily, stemming from various sources including wireless chargers, Bluetooth headset signals, elevator electronic displays, and more. Traditional solutions often struggle with such interference, as a simple walkie-talkie conversation can induce a 140mA current fluctuation, leading to a battery level display error of up to 5%. Current, being a crucial indicator for battery monitoring SoC (State of Charge), its erratic fluctuations can cause SoC jumps, creating a misleading "battery illusion" that not only detracts from user experience but also introduces risks of battery overcharging and over-discharging.

To mitigate these issues, Xinhai Technology's BMS (Battery Management System) incorporates advanced EMC (Electromagnetic Compatibility) anti-interference technology. This technology leverages a robust three-tier protection strategy encompassing "power supply, circuit, and algorithm," and has demonstrated exceptional performance in simulated power supply interference tests. By effectively filtering out electromagnetic noise, Xinhai Technology's BMS ensures accurate battery level monitoring, enhancing both user experience and battery safety.
