Abstract: A storage battery terminal structure of the present invention includes: an annular recessed groove that is arranged on an upper end portion of a cylindrical male terminal; retaining projections that are engageable with the annular recessed groove; a housing that is an outer enclosing body of a female terminal; flexible arms, each flexible arm not only having a retaining projection on an upper end portion of an inner wall of a rigid sleeve of the housing surrounding the male terminal in order to release the corresponding retaining projection from the annular recessed groove but also being formed by a pair of slits formed from an upper end of the rigid sleeve so as to interpose the corresponding retaining projection therebetween; and a release button that is arranged on an upper end portion of the rigid sleeve so as to be vertically movable so that the flexible arms can be flexed sidewards and that has slopes on a lower surface thereof, the slopes facing sidewards.

Abstract: An electric power system for an automotive vehicle is provided with a generator to which a 48-volt battery, a blower motor and a DC--DC converter are connected in parallel. An output terminal of the converter is connected to a load which is constituted by a 12-volt battery, a head lamp, a vehicle speed sensor and a resistance to which a switch is connected in series. The system is further provided with a voltmeter for detecting a voltage value of the 12-volt battery and an ammeter for detecting a load current applied to the load, a controller for controlling the converter and the switch. The controller controls the converter to start operation and the switch to be turned on when the voltage value detected by the volt-meter is lower than a first predetermined value and the load current detected by the ammeter is smaller that a second predetermined value. Accordingly, an operating period of the converter is shortened and therefore an energy loss generated in the system is suppressed.
