Latest Patents

One of Meng Chen's 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 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 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 and used to model the State of Health (SOH) value for sorting batteries.

Another significant patent is "Real-time AC-impedance inspection using limited-energy on-board AC excitation for battery management system." This patent describes a Battery Management System (BMS) that inspects a battery pack using AC impedance. The BMS utilizes a controller to drive a Pulse-Width Modulation (PWM) output signal to an on-board excitation regulator. This regulator modulates a limited energy unit, such as a capacitor, to generate an AC excitation signal. The system allows for real-time inspection of battery cells during various modes, including charging, discharging, and idle, without requiring an external power supply.
