Document Type and Number:
Japanese Patent JP2018048913
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a device for estimating the parameter of a battery which can increase the accuracy of the estimation of a parameter.SOLUTION: A parameter estimation device 1 for a battery 4, which estimates the parameter of an equivalent circuit model of the battery 4, includes a controller 10 which approximates at least a part of the relation between the charge rate and the open circuit voltage of the battery 4 by a model expressed by a logistic function and estimates the parameter of the logistic function.SELECTED DRAWING: Figure 1
