The battery pack includes a battery cell; a charge switch and a discharge switch installed in a charge/discharge line of a battery cell; and a microcontroller to sense and store voltages of the battery cell, to compare the voltages of the battery cell before and after the microcontroller is reset, and to controls the charge switch and the discharge switch based on the sensed voltages of the battery cell such that the microcontroller turns off only one of the charge switch and the discharge switch when there is a change between the voltages of the battery cell before and after the microcontroller is reset.

Abstract: A control circuit for a secondary battery is disclosed. The control circuit level shifts a voltage corresponding to charge or discharge current so that the level shifted voltage can be provided to an A/D converter.

Abstract: A charging control method for a battery pack including a plurality of battery cells in which a full charge voltage value is initially set as a first voltage value. The charging control method includes: charging the plurality of battery cells to the first voltage value in an initial charge mode; and resetting the full charge voltage value to a second voltage value less than the first voltage value in a subsequent charge mode.

Abstract: A method of controlling the operation of a data flash and a battery pack capable of performing the method. In the method, writing, copying, and deleting operations are performed on two data flashes according to status flags recorded in predetermined respective locations of the data flashes. If one of the data flashes is full of data, it is possible to prevent a data flash failure from occurring when a part of the data is copied from the data flash to the other data flash or the data is deleted from the data flash.

Abstract: Provided is a semiconductor device having an anode of a Si-FRD and a cathode of a Si-SBD which are serially connected. The Si-SBD has a junction capacitance whose amount of accumulable charge is equal to or more than an amount of charge occurring at the time of reverse recovery of the Si-FRD, and has a lower breakdown voltage than the Si-FRD does.

Abstract: A battery pack adapted to automatically intercept a charge and discharge path when the temperature of a battery increases to no less than a reference temperature during a charging and/or discharging of the battery to improve stability and reliability. The battery pack includes at least one rechargeable battery; at least one posistor located on one side of the battery and connected to the battery in parallel at substantially a same time and having a resistance value which increases when the temperature of the battery increases; a first switch having one end connected to the posistor and configured to be applied with a driving voltage when the resistance value of the posistor increases; and a second switch connected to a charge and discharge path of the battery and connected to the first switch at substantially a same time to intercept the charge and discharge path when the first switch operates.
