    摘要: A method of measuring battery capacity using a voltage response signal based on a pulse current, where the method includes the steps of: measuring a voltage response signal based on a pulse current signal applied to a primary or secondary battery; performing an approximation of the measured voltage response signal to an equivalent circuit model composed of resistors, capacitors and transmission lines to determine the model parameters; and determining the unknown battery capacity from the voltage response characteristics based on a correlation between the measured capacity and the model parameters, which correlation is previously determined by a real-time discharge method, thereby takes a shorter time than a real-time discharge method and delivering efficiency and reliability in determining model parameters of an equivalent circuit which are in close correlation with the charge/discharge condition of the battery.

    摘要: A heating cooker for a microwave oven in which in a main body through which microwaves are transmitted, an upper portion of a metallic pan is closely coupled, and a heating sheet receiving the microwaves and generating heat and an insulating support are coupled in order onto an undersurface of the pan, the heating cooker including a safety device configured such that a silicone packing is provided in a section of the close coupling between the pan and the main body, and so that if internal pressure of the cooker rises abnormally, the silicone packing is decoupled from the main body so as to reduce the pressure.
