Title: Wenfeng Yue and Battery State-of-Charge Innovation.

Introduction

Wenfeng Yue is an inventor based in Shanghai, China, associated with FCA US LLC. His patent work addresses a practical challenge in electric-vehicle battery management: accurately estimating the state of charge (SOC) of lithium iron phosphate (LFP) batteries after a vehicle has been powered off.

Latest Patents

The provided information lists one patent for Yue: “Static State of Charge Correction Techniques for Lithium Iron Phosphate Battery Systems.” The invention describes a method for correcting an LFP battery system’s SOC across a vehicle’s power-off period. When the vehicle powers off, the system records an initial SOC, starts a timer, and periodically measures battery temperature. When the vehicle powers on again, it stops the timer, calculates the average temperature, and uses a calibrated lookup table to estimate the battery’s self-discharge rate. It then calculates the resulting SOC change and subtracts that change from the initial SOC to determine a corrected value. This approach accounts for elapsed time and temperature when estimating charge loss.

Career Highlights

Yue’s listed patent reflects work on battery monitoring and control for electrified vehicles. By incorporating temperature measurements and self-discharge estimates into SOC correction, the technique aims to improve the accuracy of battery-charge information available to vehicle systems.

Collaborations

The provided data identifies Zhongjun Lu and Jingjing Zhao as Yue’s coworkers. It does not specify their roles in the patent or describe the nature of their collaboration.

Conclusion

Wenfeng Yue’s listed invention focuses on improving LFP battery state-of-charge estimates after vehicle shutdown, using elapsed time, temperature data, and self-discharge calculations.
