Adaptive Moving Average for Battery Voltage Noise Filtering

The patent applies dynamics by making the moving average window size adaptive rather than fixed. The window size automatically adjusts based on the detected voltage change rate - expanding when changes are rapid to capture sudden variations, and contracting when changes are gradual to smooth noise. This dynamic adjustment resolves the contradiction between stability and response speed.

The patent changes the parameter of the moving average calculation - specifically the window size - based on the voltage change rate. When the voltage changes rapidly, the window size increases to capture the sudden variation; when voltage is stable, the window size decreases to provide smoother measurements. This parameter adaptation allows the system to optimize between stability and responsiveness in different operating conditions.

The patent introduces dynamic measurement intervals that adapt to voltage change rates. When sudden voltage changes are detected, the measurement interval automatically decreases to capture the rapid variation with higher temporal resolution. When voltage is stable, the interval increases to reduce measurement overhead. This maintains simplicity while improving accuracy during critical transitions.

The system uses feedback from voltage change rate detection to adjust measurement timing. The measured voltage data feeds into a change rate calculation, which then feeds back to modify the next measurement interval. This closed-loop control ensures measurements are taken at appropriate frequencies - more frequently during rapid changes, less frequently during stable periods - thereby improving accuracy without excessive complexity.
