Title: Innovations of Yaofeng Sun in Battery Technology
Introduction
Yaofeng Sun is a prominent inventor based in Hong Kong, China. He has made significant contributions to the field of battery technology, holding a total of 12 patents. His work focuses on improving the efficiency and reliability of rechargeable batteries, which is crucial in today's technology-driven world.
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 innovative method allows for the screening of 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 then integrated to obtain the CC charge applied, Qcc. Following this, the battery continues charging using a Constant Voltage (CV) until the charging current falls to a midrange target. The SCCIR is calculated as the ratio of Qcc to (Qcc + Qcv), which is then used to model the State of Health (SOH) of the battery through a neural network.
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 until a voltage target is reached, and the current is integrated to obtain the CC charge applied, Q. The battery then continues charging with a Constant Voltage until the charging current falls to a minimum target. The CCIR is calculated as the ratio of Q to (Q + Q), and this value is used to model the SOH for sorting the battery for reuse or disposal.
