Abstract
Disclosed is an apparatus and method for estimating a state of charge (SOC) in a battery, the apparatus including a detector unit; a soft computing unit for calculating and outputting a battery SOC estimation value by processing a current, a voltage and a temperature detected by the detector unit using a computing algorithm, which is a fuzzy algorithm implemented as a neural network, the soft computing unit storing the battery SOC estimation value in a memory, where the fuzzy algorithm has a form expressed as F=Φ(P,X)W, where Φ is one of a fuzzy radial function, a radial basis function, and an activation function in the neural network, P is a learning parameter, X is an input, and W is a weight to be updated during learning.
