摘要： A lead acid battery device includes a lead acid battery, a charge control unit to charge the lead acid battery by alternately and repeatedly performing high voltage charging, in which a pulsed high voltage is applied to the lead acid battery, and low voltage charging, in which a low voltage lower than the high voltage is applied to the lead acid battery, and an internal resistance calculation unit to calculate an internal resistance of the lead acid battery based on the voltage difference and the current difference of the lead acid battery between a condition at which the pulsed high voltage is applied and a condition at which the pulsed high voltage is not applied.

摘要： With a conventional pulse charging method, a low voltage value for the pulse voltage is set to zero volts. When the low voltage value is low in this manner during charging, there is a problem that the negative pole of a secondary battery deteriorates. Provided is a secondary battery apparatus including a secondary battery and charge/discharge control apparatus that controls charging and discharging of the secondary battery. The charge/discharge control apparatus repeatedly performs, in an alternating manner, high voltage charging of applying a pulsed high voltage to the secondary battery and low voltage charging of applying a low voltage that is higher than 0 V and lower than the high voltage to the secondary battery.
