Title: Shanqi Tang and Battery Charge Estimation Innovation.

Introduction

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

Latest Patents

The supplied information lists one patent for Tang: “Static State of Charge Correction Techniques for Lithium Iron Phosphate Battery Systems.” The technique records the battery’s initial SOC when the vehicle powers off, starts a timer, and periodically measures battery temperature. When the vehicle powers on again, the system uses the elapsed time and average temperature with a calibrated lookup table to estimate the battery’s self-discharge. It then calculates the resulting SOC change and subtracts that change from the initial SOC to produce a corrected estimate. This approach is designed to improve charge estimates after periods when the vehicle is not operating.

Career Highlights

Tang’s listed patent reflects work on battery-management methods for electrified vehicles. By accounting for self-discharge and temperature during vehicle downtime, the invention aims to support more reliable battery charge estimates. The supplied information identifies FCA US LLC as his company affiliation.

Collaborations

The supplied information names Zhongjun Lu and Jingjing Zhao as Tang’s coworkers. Their specific roles in the patent or related work are not provided.

Conclusion

Shanqi Tang’s listed invention focuses on correcting LFP battery charge estimates after vehicle power-off by incorporating elapsed time, temperature, and self-discharge. The work highlights the importance of accurate battery monitoring in electrified vehicles.
