Title:
METHOD AND DEVICE FOR ESTIMATING BATTERY STATE
Document Type and Number:
Japanese Patent JP2021067674
Kind Code:
A
Abstract:
To provide a method and device for estimating the battery state.SOLUTION: A battery state estimation method disclosed herein comprises: determining a state variation of a battery using a voltage difference between a sensed voltage of the battery and an estimated voltage of the battery estimated by an electrochemical model corresponding to the battery; updating the internal state of the electrochemical model based on the state variation of the battery; and estimating state information of the battery based on the updated internal state of the electrochemical model.SELECTED DRAWING: Figure 2
