蓄电装置温度测定方法
摘要：
本发明的目的在于提供一种蓄电装置温度测定方法，相对于受到蓄电装置的劣化状态的影响、所测定的内部阻抗的测定值发生变动、无法获得准确的蓄电装置的内部温度的、现有的蓄电装置的温度测定方法，能够准确地测定蓄电装置的内部温度。该蓄电装置温度测定方法特征在于，利用蓄电装置(1)的离子难以追随的频率(例如10kHz以上的频率)的信号来测定蓄电装置(1)的内部阻抗，并根据内部阻抗的测定值来算出蓄电装置(1)的内部温度。
摘要（英）：

It is an object to provide an electrical storage device temperature measuring method for accurately measuring the internal temperature of an electrical storage device as compared to an existing electrical storage device temperature measuring method by which the internal temperature of the electrical storage device cannot be accurately obtained since a measured value of a measured internal impedance varies due to influence of a deterioration state of the electrical storage device. An internal impedance of an electrical storage device (1) is measured by using a signal of a frequency which ions in the electrical storage device (1) are difficult to follow (e.g., a frequency equal to or higher than 10 kHz), and an internal temperature of the electrical storage device (1) is calculated from a measured value of the internal impedance.
