| Abstract(in English) | With the advent of the large-scale popularization of Lithium-ion secondary batteries, the accuracy as well as low cost should be indispensable for measurement systems. Among the SOC estimation technology, the Kalman filter method is recognized as a promising method. However, Kalman filtering does not consider current noise (input noise). In the SOC estimation system, both voltage and current measurements contain noise. In this paper, we describe the high accuracy battery SOC estimation algorithm consider the battery terminal voltage observation noise and the current observation noise. |
