Claims

[Scope of utility model registration request]

a starter motor that starts the internal combustion engine; a first alternator and a second alternator that are rotationally driven by the operation of the internal combustion engine; and a first alternator that rectifies the alternating current outputs of the first and second alternators, respectively. a first rectifier and a second rectifier, a first storage battery and a second storage battery that are charged by the rectified outputs of the first and second alternators, respectively, and the first and second alternators. A first voltage regulator and a second voltage regulator that control the field current flowing through each field coil to control the AC outputs of the first and second alternating current generators to desired values; A normally open first switch means and a second switch means connected in series to each field coil of the alternator are connected to each other when the starting switch is closed and at least one of the first and second alternators is connected in series. A storage battery discharge prevention device having a self-holding function that closes the first and second switch means by an output and closes the first and second switch means until a predetermined time has elapsed after the rotation of the first and second alternating current generators has stopped. A DC three-wire charging device for a vehicle, characterized in that the first and second switch means are opened after the predetermined time period has elapsed to prevent discharge of the first and second storage batteries. .
