Title: Zhi Liu: Innovator in Battery Technology

Introduction

Zhi Liu is a prominent inventor based in Ningde, China, known for his significant contributions to battery technology. With a total of two patents to his name, Liu has developed innovative methods and devices that enhance the performance and safety of lithium batteries.

Latest Patents

Liu's latest patents include a "Charge Current Test Method and Device" and a "Charge Test System." This application provides a charge current test method and device, along with a charge test system. The method involves charging a to-be-tested battery at a first current under a first temperature until the voltage reaches a preset cutoff voltage. Charging is stopped whenever an increment of the state-of-charge value reaches a preset value during the charging process. After a duration of stopping charging reaches a first preset time length, the charging continues. The impedance of the to-be-tested battery is calculated during this time, allowing for the determination of a maximum state-of-charge value that can be reached when charging at the specified current and temperature.

Another notable patent is the "Method and Device for Detecting Abnormality of Lithium Battery, Battery Management System, and Battery System." This application provides a method for detecting abnormalities in lithium batteries. The method includes obtaining a state-of-charge (SOC) value during the charging process and changing the charge current at specific SOC values to obtain response signals. By analyzing these signals, the method can determine whether the lithium battery is functioning abnormally, enabling non-destructive detection with high accuracy.
