摘要：

Recent years have seen some railway vehicles equipped with secondary batteries on board to improve their energy saving performance. Such vehicles need accurate and stable SOC (state of charge) estimation, which is important for managing battery energy. This paper reports on a SOC estimation method for on board lithium ion batteries developed for the contact-wire and battery hybrid electric railway vehicle. This method enables stable SOC estimation and automatic tuning of parameters, such as battery capacity and battery inner resistance. These characteristics of the estimation method were evaluated by way of running tests on the JRShikoku Yosan railway line.
