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： An ignition timing control method for an internal combustion engine wherein a plurality of correction values for ignition timing are stored in memory means beforehand as a function of an output voltage from a variable voltage creating means which is humanly adjustable and the rotational speed of the engine. The output voltage from the variable voltage creating means and the rotational speed of the engine are detected, and one of the correction values is read, which corresponds to the detected output voltage and the detected rotational speed of the engine. Then, the ignition timing is corrected by the use of the read one correction value. Further, a value of a parameter indicative of load on the engine is detected, and the ignition timing control is executed when the detected value of the parameter is above a predetermined value. Alternatively, in place of the correction values, address values are stored in memory means. One of the address values is read, which corresponds to the detected output voltage and converted to a numerical value in the number system with a predetermined number as the base. The figures of the numerical value correspond to respective regions of the engine rotational speed. A correction value for correcting the ignition timing is determined in accordance with one of the figures of the numerical value corresponding to the region of the engine rotational speed in which the engine is detected to be operating.
