Description of the Related Art Although electric vehicles are said to be low-pollution vehicles, they are not widely used at present because of long time per charge and short running distance per charge. However, in recent years, batteries for electric vehicles have been improved, so that the charging time per charge can be extremely short, and the traveling distance per charge can be increased. For this reason, if the charging stand for electric vehicles is installed at every fixed distance, traveling over a long distance becomes possible.

線を取り外すには安全性においても問題がある。The voltage of a storage battery mounted on an electric vehicle is as high as 300 to 500V. In order to obtain this voltage, a configuration is adopted in which about 300 unit cells constituting a storage battery are connected in series. If hundreds of cells are connected in series, it is extremely difficult to find several defective cells among them. The reason for this is that, in order to detect a defective cell, usually hundreds of cells connected in series must be completely disconnected and each cell must be checked individually to find a defective cell. Because. Also, there is a problem in terms of safety when removing the wiring of the battery to which several hundred volts are applied.
