摘要： A charged state detecting apparatus for a secondary battery is provided, which can suppress deterioration in the accuracy of detecting a charged state, such as an SOC, the deterioration being caused by variation of a polarization state of a battery. The charged state detecting apparatus stabilizes an amount of polarization of the battery, stops power generation upon confirmation of the stabilization of the polarization amount, and sufficiently alters the current of the battery to sample a required number of data pairs of voltage and current of the battery. Using these data pairs, the charged state detecting apparatus detects a charged state, such as the SOC, of the battery.

摘要： A neural network type of apparatus is provided to detect an internal state of a secondary battery implemented in a battery system. The apparatus comprises a detecting unit, producing unit and estimating unit. The detecting unit detects electric signals indicating an operating state of the battery.

摘要： An apparatus and method of neural network type are provided to detect an internal state of a secondary battery implemented in a battery system. Electric signals indicating an operating state of the battery is detected and, using the electric signals, information indicating the internal state of the battery is calculated on the basis of neural network calculation, in which the information reflects a reduction in an effect of polarization of the secondary battery. Using the electric signals, input parameters required for calculating the internal state of the battery is calculated. The input parameters may include, as one input parameter, a polarization-related quantity to correct the effect of the polarization in an output parameter (such as SOC and/or SOH) from the neural network. Further, the input parameters may include, as one input parameter, a functional value already subjected to the correction for correcting the effect of the polarization.

摘要： A current Ibe and a voltage Vbe before a large current discharge in a secondary battery are stored in a memory. Plural voltage-current pairs are detected and stored in the memory during the large current discharge. Next, a regression curve (or a regression line) is obtained based on the plural voltage-current pairs stored in the memory using a well-known method. A discharge current Ip which exceeds a current-sensor detectable range is input in the regression curve to obtain a voltage Vp. A maximum discharge coordinate is set using the discharge current Ip and the voltage Vp. An internal resistance Rin of the secondary battery is calculated based on an inclination of a line that connects the coordinates (Ibe, Vbe) and (Ip, Vp).

摘要： An apparatus is provided to calculate a quantity indicating a charged state of an on-vehicle battery. The battery powers a starter starting up an on-vehicle engine. In the apparatus, a plurality of pairs of data consisting of current and voltage of the battery are acquired at predetermined sampling intervals during a cranking period of the engine in response to starting up the starter. At intervals, a value of an internal resistance of the battery is calculated based on the plurality of pairs of data of current and voltage. The internal resistance is one kind of the charged-state indicating quantity. An open voltage difference is calculated, which is a difference between a pseudo circuit-open voltage of the battery given before starting up the starter and a pseudo circuit-open voltage of the battery given after the cranking period. The value of the internal resistance is corrected using the open voltage difference.
