    摘要: A method and apparatus for operating a battery system. The apparatus comprises a housing, a plurality of battery cells, and a bypass circuit. The plurality of battery cells is connected in a series circuit within the housing. The plurality of battery cells is configured to supply a total voltage output. The bypass circuit is configured to determine whether a voltage output from a battery cell in the plurality of battery cells has fallen below a selected threshold. The bypass circuit is further configured to bypass the battery cell in the series circuit in response to a determination that the voltage output from the battery cell has fallen below the selected threshold.

    摘要: A drive control circuit (200) of a backlight (220) includes a drive circuit (240) that drives the backlight (220), a voltage detection unit (250) that detects whether or not a supply voltage Vp from a battery (210) is less than or equal to a threshold value, and a controller (260) that controls the operation of the drive circuit (240). When the supply voltage Vp from the battery (210) is less than or equal to the threshold value, the drive circuit (240) changes a drive current to be supplied to the backlight (220) to a low current value. Furthermore, in response to a change in the drive current, the controller (260) provides, to the drive circuit (240), a PWM signal to extend a time period for which the backlight (220) are on.

    摘要: In a battery voltage monitoring device including a battery voltage monitoring IC coupled to a plurality of unit cell groups configuring an assembled battery by being serially coupled in multiple stages and measuring voltage of each of the unit cells and a system control unit controlling the whole, communication between the system control unit and the battery voltage monitoring ICs is realized in consideration of fail-safe. The system control unit and the plurality of battery voltage monitoring ICs are coupled to each other by a communication path using a daisy chain. The battery voltage monitoring IC has a placement setting pin designating, by a binary code, a unit cell group to which the IC is coupled, in the unit cell groups. When it is detected that the Hamming distance between the code indicative of coupling to a group of the highest potential or a group of the lowest potential and a state actually set in the placement setting pin is 1, occurrence of failure such as line disconnection, short-circuit, or the like in the placement setting pin is determined, and an output to a communication path is interrupted by being set to high impedance.
