摘要： The power source apparatus is provided with a shunt resistor connected in series with batteries, and a current computation circuit that detects the voltage induced by current flow through the shunt resistor to compute battery current. The shunt resistor is provided with a pair of current flow terminals at two separated points on a metal plate connected in series with the batteries via connecting leads, and a pair of voltage detection terminals on a side of the metal plate between the pair of current flow terminals. Further, the shunt resistor has interval adjustment structures to adjust the distance (L) between attachment points where the connecting leads attach to the pair of current flow terminals. The distance (L) between lead attachment points is adjusted with the interval adjustment structures to finely adjust the voltage induced at the voltage detection terminals due to current flow between the two attachment points.

摘要： An electric power source for a motor vehicle is equipped with a welded state discriminator, and while a positive-side contactor and negative-side contactor are controlled to be switched off, the welded state discriminator detects a voltage of a positive-side contactor or negative-side contactor on its loading side with respect to a connecting point of a battery unit on a positive side and a battery unit on a negative side. Accordingly, when in a plus voltage where the detected voltage thus obtained is larger than a predetermined voltage, the positive-side contactor is judged to be in a welded state, and when in a minus voltage where the detected voltage is larger than the predetermined voltage, the negative-side contactor is judged to be in a welded state.

摘要： An electric power source for a motor vehicle is so constructed and arranged that an interlock circuit detects a disconnected state of an interlock wire and turns off a contactor. The interlock circuit includes: a current output circuit outputting a detectable current via a diode to the interlock wire; a first current detection subcircuit connected via the interlock wire and the diode to the current output circuit; a second current detection subcircuit connected to a connection point operatively located between the current output circuit and the diode; and a judgment circuit. In the interlock circuit, when the detectable current is detected at the second current detection subcircuit and when the detectable current is not detected at the first current detection subcircuit, the judgment circuit judges the interlock wire to be in a disconnected state and cuts off the contactor.
