Title: Ruobing Ren and Battery Capacity Estimation

Introduction

Ruobing Ren is an inventor based in Shenzhen, China, associated with O2 Micro, Incorporated. His patent work addresses the challenge of estimating a battery’s remaining capacity by combining measurements and calculations taken under different operating conditions.

Latest Patents

Ren is named on 1 patent: “Calculating a Remaining Capacity of a Battery.” The method records how long a battery monitor remains in sleep mode. When that time exceeds a preset period, it uses a stored open-circuit voltage measurement to determine a remaining-capacity ratio. It also estimates charge consumption from a preset current and the sleep time, then calculates another ratio using the consumed charge, a stored capacity value, and the battery’s preset total capacity. Finally, it evaluates battery-parameter readings and combines the resulting ratios to determine the battery’s current remaining capacity.

Career Highlights

Ren’s listed invention focuses on improving battery-capacity estimates by drawing on multiple sources of information, including voltage, elapsed sleep time, estimated charge consumption, and battery parameters. This approach is designed to account for battery behavior while the monitor is asleep as well as when parameter readings are available.

Collaborations

Ren is associated with O2 Micro, Incorporated. His listed coworkers include Yi Yuan and Sterling Du.

Conclusion

Ruobing Ren’s patent contribution centers on a method that combines voltage measurements, charge estimates, and battery parameters to calculate remaining capacity.
