Latest Patents
One of his latest patents is titled "Adaptive battery parameter extraction and SOC estimation for lithium-ion battery." This innovative system and method estimate internal parameters of a lithium-ion battery to provide a reliable state-of-charge estimate. The method employs a two RC-pair equivalent battery circuit model to estimate various battery parameters, including open circuit voltage, ohmic resistance, double layer capacitance, charge transfer resistance, diffusion resistance, and diffusion capacitance. Additionally, it utilizes the equivalent circuit model to derive a difference equation for adapting the battery parameters.
Another significant patent is the "Excessive current detection controls method." This method is designed to control the charging and discharging of a battery pack in electric or hybrid vehicles to prevent overheating damage. It involves monitoring the current flowing into or out of the battery pack, integrating the root mean square (RMS) current over a time window, and comparing it to a threshold. If the time-integrated RMS current exceeds the threshold, a closed-loop proportional-integral (PI) controller is activated to regulate power input or output, ensuring the safety of the battery cells.
