Title: Yi Jiang and Battery Charge Estimation Innovation.

Introduction

Yi Jiang is an inventor associated with Wuhan, China, and FCA US LLC. His patent work addresses a practical challenge in electric-vehicle battery management: accurately estimating the state of charge of lithium iron phosphate batteries after a vehicle has been powered off.

Latest Patents

Jiang is associated with 1 patent: “Static State of Charge Correction Techniques for Lithium Iron Phosphate Battery Systems.” The invention describes a method for correcting a battery system’s estimated state of charge after a vehicle has been switched off. It records the initial charge estimate, tracks the power-off duration, and periodically measures battery temperature. When the vehicle powers on again, the method uses the elapsed time and average measured temperature with a calibrated lookup table to estimate the battery’s self-discharge. It then subtracts the resulting charge change from the initial estimate to calculate a corrected state of charge.

Career Highlights

Jiang’s listed patent work is connected to FCA US LLC and focuses on battery monitoring for electrified vehicles. By accounting for self-discharge during periods when a vehicle is off, the technique aims to improve the reliability of charge estimates for lithium iron phosphate battery systems.
