    摘要: An apparatus for detecting an integrated value of current flow. The apparatus includes an integrator having an integration capacitor, to which a current sensor voltage is inputted, for outputting an output voltage corresponding to an integrated value of the current sensor voltage, and a resetting circuit for clearing integration electric charges accumulated in the integration capacitor to reset the integrator when the output voltage has reached an upper threshold value or a lower threshold value. The apparatus also includes a counter for counting the number of resets of the integrator in an upper direction or in a lower direction, and a connection-polarity inverting circuit for inverting a polarity of inputting of the current sensor voltage to the integrator, a polarity of connecting of the integration capacitor to the integrator and a counting direction of the counter, alternatively, at a regular time interval and synchronously. An integrated value of current flow is obtained on the basis of a count value of the counter.

    摘要: The present invention provides apparatus for detecting the integrated value of current flow, apparatus for detecting the value of current flow and a battery pack employing those apparatus each of which becomes insensitive to the offset in an operational amplifier. Each apparatus and the battery pack includes: a current sensor resistor inserted in series with a current path; an integrator; an input status selector; an integration capacitor connected to the integrator; and a connection-polarity inverter of the integration capacitor provided between the integrator and the integration capacitor. The input status selector switches alternately so as to provide two statuses of a status a and a status b at intervals of a predetermined time which are equal to one another, and in the status a, introduces therethrough the voltage which corresponds to the battery current value and which is developed across terminals of the current sensor resistor into an input of the integrator, while in the status b, inverts the polarity of the current sensor voltage developed across the terminals of the current sensor resistor to introduce therethrough the resultant voltage into the input of the integrator, or to introduce therethrough the voltage of zero to the input of the integrator.
