    摘要: The battery system has a current detection circuit 2, an amplifier 6, and a detection circuit 7 that detects the current flowing through batteries 1 from amplifier 6 output. The current detection circuit 2 is provided with a voltage source circuit 8 that supplies a test voltage to the input-side of the amplifier 6. Current detection lines 10 connect the current detection resistor 5 to the input-side of the amplifier 6, and the detection circuit 7 stores a reference voltage corresponding to the current detection lines 10 in the connected state. When the voltage source circuit 8 supplies the test voltage to the input-side of the amplifier 6, the detection circuit 7 compares the amplifier 6 output voltage with the reference voltage. The detection circuit 7 detects an open-circuit in the current detection lines 10 by the shift in voltage from the reference voltage.

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, so that 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.
