摘要： PROBLEM TO BE SOLVED: To highly accurately calculate the internal resistance of a secondary cell for a vehicle, without having to use a current sensor of a large current range.
SOLUTION: A current value Ibe and a voltage value Vbe, immediately prior to large current discharge, are stored as a precharging coordinate point (S303). During this large-current discharge, a large number of voltage-current pairs of currents Ib and voltages Vb only for the periods of currents within a predetermined current range are stored (S304), and from the stored large number of voltage-current pairs a regression curve (regression line will do, as well) is found by a hithertofore-known method (S305). By substituting a predetermined discharge current value Ip, which is larger than the current values in a detectable current range of a current sensor, in the regression curve, a voltage value Vp is calculated, and the current value Ip obtained and makes the voltage value Vp a maximum discharge coordinate point (S306). Next, the internal resistance value Rin is calculated from the current value Ibe found, the voltage value Vbe, the current value Ip and the voltage value Vp (S307). By doing so, the internal resistance of the secondary cell for the vehicle can be detected with accuracy that is significantly higher than that of the conventional types.

摘要： PROBLEM TO BE SOLVED: To prevent a decline in the accuracy of deciding an SOC (a charging rate) caused by variations in polarization state.
SOLUTION: The amount of polarization of a battery is stabilized (s202 to s205). After stability in the amount of polarization has been confirmed (s205), the generation of electricity is stopped, and the current of the battery is sufficiently changed to collect a necessary number of voltage/current data pairs of the battery (s205, s206). Using these data pairs, the SOC (the charging rate) is estimated (s208, s209).

SOLUTION: The number of brief changes Nac indicating a frequency in which an accelerator opening degree Acc is less than a predetermined opening degree A2 of a predetermined opening degree A1 or below within predetermined time after exceeding the predetermined opening degree A1 is set (S410). The threshold for the start Astart is set to have a tendency to become larger as the set number of brief changes Nac is greater, and the threshold for the stop Astop is set to have a tendency to become smaller as the number of brief changes Nac is greater (S420 to S450).
