Title: Minjie Xu: Innovator in Battery Technology
Introduction
Minjie Xu is a prominent inventor based in Hong Kong, CN. He has made significant contributions to the field of battery technology, holding a total of 5 patents. His innovative approaches focus on improving the efficiency and reliability of rechargeable batteries.
Latest Patents
One of his latest patents is titled "Fast screening of rechargeable batteries using sectional constant-current impulse ratio (SCCIR) calibration with constant-current followed by constant-voltage charging." This method screens used batteries based on a measured Sectional Constant-Current Impulse Ratio (SCCIR). The process involves partially charging a used battery over a small voltage range using a Constant Current (CC) until a voltage target is reached. The current is integrated to obtain the CC charge applied, Qcc. The battery is then charged using a Constant Voltage (CV) until the charging current falls to a midrange current target. The SCCIR is calculated as the ratio of Qcc to (Qcc + Qcv) and is used to model the State of Health (SOH) value for sorting.
Another notable patent is the "Fast screening method for used batteries using constant-current impulse ratio (CCIR) calibration." This method also screens used batteries based on a measured Constant-Current Impulse Ratio. The battery is charged using a Constant Current (CC) until a voltage target is reached, and the current is integrated to obtain the CC charge applied, Q. The battery continues to be charged using a Constant Voltage (CV) until the charging current falls to a minimum current target. The CCIR is calculated as the ratio of Q to (Q + Q) and is input to a calibration curve function to obtain a modeled SOH value for sorting the battery for reuse or disposal.
