  • time domain parameter extraction method for Thevenin Equivalent Circuit battery models
    IEEE Transactions on Energy Conversion, 2014
    Co-Authors: Ari Hentunen, Teemu Lehmuspelto, Jussi Suomela
    Abstract:

    This paper presents an analytical time-domain-based parameter identification method for Thevenin-Equivalent Circuit-based lithium-ion battery models. The method is based on the analysis of voltage-relaxation characteristics of pulse discharge and pulse charge experiments, and the method can be used for both discharge and charge operation with any number of parallel resistor-capacitor branches. The use of the method is demonstrated for a second-order model and validated with a real-world duty cycle. Experimental results for a commercial lithium-ion battery module are presented.

  • Comments on "SPICE-compatible models for multiconductor transmission lines in Laplace-transform domain" [with reply]
    IEEE Transactions on Microwave Theory and Techniques, 1999
    Co-Authors: J.m. Gomez, J.i. Alonso, A R Djordjevic
    Abstract:

    For the original paper see ibid., vol. 45, no. 5, p. 569-579 (1997). The aforementioned paper presents two Equivalent models compatible with SPICE for multiconductor transmission lines that permit one to analyze the time-domain response of these type of structures. One model employs a Thevenin Equivalent Circuit and the other model is based on a hybrid model. Both models use mode decoupling in the frequency and contain controlled sources in the Laplace-transform domain. This technique allows one to handle lossy lines with frequency-dependent parameters. Here the commenters point out a misprint that they have detected in Djordjevic's paper. In reply the author expresses thanks for the pointing out of the error.

  • Thevenin model of lithium-ion battery with variable parameters
    Chinese Journal of Power Sources, 2013
    Co-Authors: Zhang Yang
    Abstract:

    It is important for wind storage system to operate with an efficient energy storage battery. Thevenin model is contrary to PNGV model which has a high precision and large computing. An improved Thevenin Equivalent Circuit model was proposed, amending the determination method of parameters through taking 18 Ah lithium-ion battery as a research object. Constant current pulse experiment was adopted to determine the parameters of the improved model whose parameters were variable with the change of battery state, conventional and improved model was simulated based on PSCAD. The result shows the improved model has low computational complexity and accurate result compared with the conventional model. Therefore, it can provide a reference for the simulation of the battery energy storage system.
