A power supply device in which bars BB extend in one direction and connect the terminals of the battery cells adjacent to each other. The lines () are electrically connectable to the bars BB. The tabs TB electrically connect the bars BB to the lines (). The bar BB is formed of a clad plate formed of a first metal (A) and a second metal (B). The bar BB includes first and second holders (and), and a tab holder. The first and second holders (and) are arranged in the first and second metals, respectively, and hold the terminals at holding positions. The tab holder is arranged in the first metal (A), and holds the tab TB at a holding position. The impedance between the first holder () and the tab holder is substantially equal to the impedance between the tab holder and the second holder ().

The signal output circuit of the highest rank state detection section outputs an abnormal signal that is generated by the processing device when an abnormality is detected by the abnormality detection section. When no abnormality is detected, a normal signal is generated by the processing device and output as the detection signal. In each state detection section other than that of the highest rank, the signal output circuit outputs an abnormal signal generated by the processing device when an abnormality is detected by the abnormality detection section, and outputs the detection signal input from a higher rank state detection section when no abnormality is detected.

A plate-shaped portion of each of separators has a cross-sectional shape bent in a concavo-convex shape in a vertical direction. The plate-shaped portion of each of the separators has a flat cross-sectional shape. The plurality of separators are arranged parallel to one another to alternately line up. One surface of each of the battery cells abuts on the plate-shaped portion of the separator, and the other surface abuts on the plate-shaped portion of the separator. Thus, a spacing between the battery cells, which are adjacent to each other with the separator sandwiched therebetween, becomes equal to the thickness of the plate-shaped portion, and a spacing between the battery cells, which are adjacent to each other with the separator sandwiched therebetween, becomes equal to the thickness of the plate-shaped portion.

One state detector detects an abnormal state or a normal state relating to charge and discharge of a battery cell group in one battery module, and generates one detection signal representing the detected state. Another state detector detects an abnormal state or a normal state relating to charge and discharge of another battery cell group in another battery module, and generates another detection signal representing the detected state. One operation processing device sends the one detection signal generated by the one state detector to an external object. Another operation processing device sends the other detection signal generated by the other state detector to the external object. The one detection signal generated by the one state detector is transmitted to at least one of the other operation processing device and the other state detector via a signal line.

A capacity maintenance ratio determination device includes an impedance measurement unit and a capacity estimation unit. An alternating signal is applied from a signal generator to a battery. Frequency characteristics of AC impedance are calculated by the impedance measurement unit based on a response signal output from the battery in response to the alternating signal. A feature frequency is determined from the calculated frequency characteristics. The capacity estimation unit includes a memory and a determination unit. A correspondence relationship among a temperature of the battery, the feature frequency and a capacity maintenance ratio is stored in the memory. The determination unit determines the capacity maintenance ratio of the battery based on the temperature of the battery detected by a temperature detector, the determined feature frequency and the correspondence relationship stored in the memory.

In an automatic dial telephone that is usuable in a motor vehicle, when a voice input is provided during a period in which input of the names of called parties is awaited, a voice pattern of the name of the called party is compared with reference patterns of called parties stored in reference pattern storing device, to determine the degree of the similarity therebetween. The names of the called parties are output to a user in the order of decreasing degree of similarity. Each time the name of a called party is output, a command word for confirmation is a waited from a user for a predetermined time period. When a voice confirmation command is input and is recognized during this waiting period, a telephone number corresponding to the name of the called party is supplied to a channel. Consequently, the command word for confirmation may be input only if the name of the called party outputted is one desired by the user. Sensors continually monitor the driving condition of the motor vehicle in which the telephone is installed. When the operation of the steering wheel or brakes of the motor vehicle exceeds a predetermined threshold or the speed of the motor vehicle is excessive, the sensors generate safety signals that inhibit the operation of the telephone.
