Battery management system for open cell detection in batteries
A recently filed patent (Publication Number: US20230402664A1) describes a battery management system designed to efficiently control the charging and discharging of multiple battery units and capacitors. The system includes a balance unit that alternates between enabling and disabling states, comparison circuitry to monitor voltages on the capacitors, and a judging unit to determine the operability of the battery connection based on the comparison results. The system ensures that the capacitors are fully charged or discharged within specific time periods depending on the status of the battery units, enhancing the overall performance and safety of the battery management process.
Moreover, the patent also details a method for controlling the charging and discharging of the capacitors in the battery management system. By enabling and disabling the balance unit at specific intervals, the method ensures efficient energy transfer between the battery units and capacitors. Additionally, the method includes provisions for protecting the battery units from overvoltage and under-voltage conditions, further enhancing the safety and reliability of the battery management system. Overall, the patent highlights innovative techniques for optimizing the performance of battery systems while maintaining a high level of safety and efficiency in energy management.
