| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Lead acid batteries have still important position in rechargeable electrical energy storage devices because of its low-cost, high-reliability and so on. One of the problems of rechargeable batteries is difficulty in estimating state of charge (S.O.C.) and state of health (S.O.H.). Authors have proposed new estimation method of S.O.C. and S.O.H. for NiMH batteries using system identification method. In this paper, the proposed method was tried to apply to lead acid batteries at first. After some experiments and considerations, a new inner equivalent model should be applied to lead acid batteries. Using new model, relationship between S.O.C. and model parameters were analyzed and authors found that some of these parameters have effective correlation to S.O.C. | |
