Title: Xianzhi Gong: Innovator in Power Systems

Introduction

Xianzhi Gong is a notable inventor based in Novi, MI (US), recognized for his contributions to power system technologies. He holds 2 patents that showcase his innovative approach to enhancing the efficiency and reliability of electrified vehicles.

Latest Patents

One of his latest patents is titled "Method and system for detecting contactor weld." This invention involves a power system that includes a battery and a controller. The controller is designed to inhibit the charge of the battery based on voltage or current values sensed before and after contactors connected to the battery are commanded to open. It indicates that a leakage resistance associated with one of the contactors increases after it is commanded to open, and it monitors the duration of a continuous voltage drop across another contactor after it is commanded to open, exceeding a specified threshold.

Another significant patent by Xianzhi Gong is the "Adaptive open circuit voltage based SOC reset method at the end of charge based on temperature and charging rate." This invention pertains to an electrified vehicle that operates according to the state of charge of its traction battery. The controller is programmed to manage the traction battery based on its state of charge and generates an adaptive relaxation time and compensation voltage that vary with temperature and charge rate. After the completion of a charge cycle, the controller updates the state of charge based on the difference between the measured voltage of the traction battery and the adaptive compensation voltage.
