摘要： A charging system supplies a charging current of a constant value (Icc) to a secondary battery, performs a constant-current charging using the charging current until the CCV of the secondary battery reaches a predetermined threshold voltage (Vcc), and repeats a predetermined number of times (N times): —reducing the charging current currently being supplied by a predetermined current reduction amount (ΔIc), —setting the reduced charging current as a new charging current, and —performing the constant-current charging using the new charging current until the CCV of the secondary battery increases by a predetermined voltage increase amount (ΔVx), and then stops the supply of the charging current. The current reduction amount (ΔIc) is set so that the CCV of the secondary battery is larger than the fully-charged voltage (Vfull) of the secondary battery when the charging current currently being supplied is reduced by (ΔIc).

摘要： A power storage apparatus including a battery and a control circuit controlling charging/discharging of the battery, wherein the control circuit determines, when a predetermined time period that has elapsed after the charging/discharging of the battery was ended is shorter than a polarization elimination time period extending from a time at which the charging/discharging of the battery was ended to a time at which polarization of the battery was judged to have been eliminated, an estimated open-circuit voltage for the battery after the elimination of the polarization of the battery; determines the difference between a first estimated charge state and a charge state determined by a time at which the estimated open-circuit voltage was estimated; and determines a second estimated charge state by summing the state of charge determined by the time at which the estimated open-circuit voltage was estimated and the product of the difference and the reflection coefficient.

摘要： When it has been determined according to a voltage detected by a voltage detecting unit 31 that a voltage detection line 23 between a focused-on battery 21 and the voltage detecting unit 31 has been broken, operations of each of switches 22 are controlled to separate a battery module 2 that includes the voltage detection line 23 from a power supply apparatus 1. When it has been determined according to the voltage detected by the voltage detecting unit 31 that the focused-on battery 21 has been overcharged or overdischarged, power input to, or output from, every battery module 2 is limited.

摘要： An abnormality diagnostic for a MOSFET switch element in a rechargeable battery pack for determining a short circuit abnormality (fusion) in a MOSFET switch element that causes a charge current to flow in. An on/off controller turns off a MOSFET causing a charge current to flow into a battery module, a start-of-charge instruction unit transmits to a charger an instruction signal to start a charging operation, and a short circuit abnormality diagnostic unit determines, based on a current sensor output, whether current is flowing through the MOSFET due to the charging operation to diagnose a short circuit abnormality in the MOSFET. After diagnosis of the MOSFET, a diagnosis of a short circuit abnormality in a MOSFET that causes a discharge current to flow out of the battery module is performed, and then a diagnosis of a short circuit abnormality in a charge relay is performed.
