METHOD AND DEVICE WITH ESTIMATING BATTERY STATE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17984401 titled 'METHOD AND DEVICE WITH ESTIMATING BATTERY STATE

Simplified Explanation

The patent application describes a device and method for estimating the state of a battery.

  • The method involves charging the battery in a constant current mode and continuously updating the state of charge value of the battery during this mode.
  • When the measured voltage of the battery reaches a certain cutoff value, the charging mode is switched to a constant voltage mode.
  • The state of charge value of the battery is then iteratively updated while in the constant voltage mode.
  • This device and method provide a more accurate estimation of the battery's state of charge during the charging process.


Original Abstract Submitted

A device and method with battery state estimation are disclosed. A method includes charging a battery in a constant current (CC) charging mode, iteratively updating a full state of charge (SOC) value of the battery while in the CC charging mode, when a measured voltage value of the battery is determined to be greater than or equal to a cutoff voltage value, switching from the CC charging mode to a constant voltage (CV) charging mode and charging the battery in the CV charging mode, and iteratively updating the full SOC value while the battery is in the CV charging mode.
