Abstract

Un selector de circuito (13) enciende y apaga conmutadores (S1, S2) de manera que el valor de resistencia de un circuito de carga/descarga (17) cambia por lo menos una vez en un período desde el inicio de una descarga en un estado en el cual el voltaje de un dispositivo de almacenamiento de energía (2) está en un voltaje de límite superior hasta que el voltaje alcanza un voltaje de límite inferior. Un estimador de carga eléctrica (14) calcula la carga eléctrica por integración en tiempo de la corriente desde un tiempo de inicio del descargado a un tiempo determinado arbitrariamente y calcula una relación entre la carga eléctrica y el voltaje del dispositivo de almacenamiento de energía (2). Un estimador de resistencia interna (15) calcula la resistencia interna en base en los voltajes y corrientes del dispositivo de almacenamiento de energía (2) en tiempos cuando los valores de resistencia son diferentes. Un estimador de energía eléctrica (16) calcula una relación entre la carga eléctrica y el voltaje abierto en base en la relación entre la carga eléctrica y el voltaje, así como la corriente y la resistencia interna del dispositivo de almacenamiento de energía (2). Durante el cargado o descargado del dispositivo de almacenamiento de energía (2), el estimador de energía eléctrica (16) estima la energía eléctrica del dispositivo de almacenamiento de energía (2) en base en la relación entre la carga eléctrica y el voltaje abierto, la resistencia interna y la corriente de carga/descarga.
