摘要： An apparatus for measuring battery voltage is provided that can detect battery voltage with high accuracy, and also can be miniaturized with cost and noise reduced. The apparatus comprises: a capacitor which is charged to the voltage of each module, switches which connect and disconnect this capacitor and the module, a voltage follower which outputs the voltage across the capacitor, and switches which connect and disconnect the voltage follower and the capacitor. For the aforementioned switches, photo MOSFETs are used. Furthermore, to prevent discharge from the capacitor, a voltage follower is installed. Therefore, by using not a complicated circuit but inexpensive and simple elements, a low cost and miniaturized apparatus for measuring battery voltage is realized.

摘要： The present invention provides a battery voltage measuring device capable of immediately detecting a breakage in the voltage measuring line in a battery voltage measuring device that detects the battery voltage. In blocks formed by connecting a plurality of secondary batteries in series, voltage sensors that detect the voltage of each block are respectively provided. In addition, before these voltage sensors noise filters are provided, and in addition, a measuring line breakage detecting resistor for detecting a breakage in the voltage measuring line is connected in parallel to each block. In a battery voltage measuring device having this type of structure, in the case that the voltage measuring line Q is broken, the voltage values V1 and V2 detected by the voltage sensors 20-1 and 20-2 become voltage values that accompany the resistance ratio of the measuring line breakage detecting resistors 60-1 and 60-2. Thereby, the voltage sensor detects a voltage that is not normally detected, and as a result, it becomes possible to immediately detect the breakage in the voltage measuring line.

摘要： A control section sets a positive side switching element of a positive side detection section and a negative side switching element of a negative side detection section to ON, thus outputting an ON signal. When the switching elements are set ON, a predetermined current outputted from a positive side constant current source and a negative side constant current source, or a portion of this current, flows through detection resistors. A ground fault decision section decides whether a ground fault has occurred in the positive or the negative side of a direct current power source, based upon the value of an output voltage detected by a positive side voltage detector, or upon the value of an output voltage detected by a negative side voltage detector. Ground faults are accurately detected with a simple structure.
