    Abstract: Upon detecting an external signal which instructs to stop discharge, an input voltage equal to or less than a set value for the prevention of overdischarge, or an output voltage equal to or more than a set value for the prevention of output of an overvoltage, a control unit (12) stops discharge to a load (40) by opening a switching element (4b) of a step-down unit (11b). Upon detecting that an external signal is reset or an input voltage equal to or more than a set value larger than the set value for the prevention of overdischarge, the control unit (12) resumes discharge to the load (40) by setting the switching element (4b) in a switching operation state or short-circuiting it.

    Abstract: Provided is a deterioration determination circuit configured by including: an SOC detection unit for detecting an SOC of a secondary battery; an internal resistance detection unit for detecting an internal resistance value of the secondary battery; a first determination unit for determining the status of deterioration of the secondary battery based on the internal resistance value detected by the internal resistance detection unit when the SOC detected by the SOC detection unit is within a range of a pre-set first range; a second determination unit for determining the status of deterioration of the secondary battery based on the internal resistance value detected by the internal resistance detection unit when the SOC detected by the SOC detection unit is within a range of a pre-set second range as a range of an SOC, in which a variation of the internal resistance of the second battery in relation to a variation of the SOC of the secondary battery is different from the first range; and a final determination unit for ultimately determining that the secondary battery is deteriorated when the first determination unit determines that the secondary battery is of the deteriorated status and the second determination unit additionally determines that the secondary battery is of the deteriorated status.

    Abstract: Methods and systems for determining a state of charge of a battery are provided. A first component of the state of charge is calculated based on a first property of the battery. A second component of the state of charge is calculated based on a second property of the battery. The first component of the state of charge is weighted based on a rate of change of the first property relative to a change of the state of charge. The second component of the state of charge is weighted based on a rate of change of the second property relative to a change of the state of charge. The state of charge is determined based on the first and second weighted components.
