Abstract: A power supply apparatus is disclosed. The power supply apparatus includes a rechargeable battery and a battery management system (BMS) for managing charging and discharging of the battery. The power supply apparatus is configured to supply an operating power to the BMS from an external power of an external power source when the external power source is in a normal state and is capable of supplying the external power to a load through the power supply apparatus. The power supply apparatus is further configured to supply the operating power to the BMS from electric energy stored in the battery when the external power source is in a state different from the normal state and not capable of supplying the external power to the load through the power supply apparatus.

The vehicle includes a battery for providing electric energy to the motor, a remaining energy-amount detector for detecting an amount of remaining energy of the battery, a distance calculator for calculating an available moving distance of the vehicle corresponding to the amount of remaining energy and a weight applied to the vehicle, and a display unit for displaying the available moving distance.

Abstract: A battery pack includes: a first battery cell group including at least one high capacity battery cell; and a second battery cell group including at least one high output battery cell and being coupled in parallel to the first battery cell group, wherein the high output battery cell is configured to output a greater current than the high capacity battery cell, the high capacity battery cell is configured to store a greater amount of electric energy compared to the high output battery cell, and the battery pack is configured to operate in one of operational modes including: a high capacity mode for outputting electric energy stored in the first battery cell group; a high output mode for outputting electric energy stored in the second battery cell group; and a mutual charge mode for charging the first battery cell group or the second battery cell group.

Abstract: A battery pack is disclosed. The battery pack has an analog front end which senses if a failure occurs in a microcontroller, and interrupts charging and discharging of the battery in response to the failure.

Abstract: A protection circuit of a battery pack capable of detecting the error of a charging device from the battery pack. The protection circuit of the battery pack having a battery cell charged by a charging device, the protection circuit including a charge switch coupled to a high current path (HCP), the charge switch disposed between the battery cell and the charging device charging the battery cell and a controller sensing a voltage or a current of the charging device during a charge stop period stopping a charging of the battery cell and determining whether an error of the charging device occurs according to the voltage or the current of the charging device.

Abstract: A secondary battery includes a protection circuit module (PCM) electrically connected to a bare cell. The bare cell is wrapped with a first sheet, a water permeable second sheet placed on the first sheet, and a submergence label placed between the first sheet and the water permeable second sheet. The submergence label indicates if the bare cell has been exposed to moisture. The label sheet further has a stacking structure, wherein the second sheet is placed on top of the first sheet and the submergence label is interposed between the first sheet and the second sheet. Accordingly, it is possible to determine whether a user has disassembled, modified, or reused the battery and it is possible to easily verify whether or not the secondary battery has been submerged in a liquid due to a user's carelessness or mistake.

Abstract: A battery pack includes a battery cell, a charge-blocking unit, a voltage sensing and balancing circuit, and a microcomputer, the microcomputer including a controller that detects at least one selected from the group of abnormal analog-to-digital conversion, abnormal voltage, and abnormal temperature of the battery cell, the controller outputting a charge control signal to the charge-blocking unit to inhibit charging of the battery cell.

Abstract: A battery pack having a function for preventing operation of the battery pack when an abnormal replacement of a battery cell is detected or preventing a use of the battery pack in which a cap has been removed. The battery pack generates an encryption code and writes the encryption code to data flash when a battery cell is normally discharged according to a first voltage, and if an abnormal power-on reset is detected on the battery cell, the battery pack may check the stored encryption code to a second encryption code generated upon power-on reset. If the codes do not match, firmware of the battery pack is deleted and/or a fuse is blown, making it is possible to prevent the battery pack from being re-used when the battery cell has been replaced or in which a cap has been removed.
