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： The current detection apparatus is provided with a current detection section (20; 30) that detects charging current and discharging current of the car driving battery (10), a level-shift circuit (40; 50) connected to the output-side of the current detection section (20; 30) that shifts the output of the current detection section (20; 30), and an A/D converter (60) connected to the output-side of the level-shift circuit (40; 50). The level-shift circuit (40; 50) shifts the current detection section (20; 30) output signal to unbalance the maximum discharging current and maximum charging current that can be detected.

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.

摘要： A power source device comprises a cell unit 12 comprising a plurality of cells 12a. Connected between a positive side terminal and a negative side terminal of the cell unit 12 is a first current line 34 having two voltage dividing resistors 30, 32 interposed therebetween, and is a second current line 22 having two protection resistors 14, 16 and two detection resistors 18, 20 interposed therebetween. An intermediate point 24 of the second line 22 is grounded to a grounding 26 via an insulation resistor 28. The voltage difference between a voltage (V1, V2) detected by the detection resistors 18, 20 and a reference voltage (Vc) obtained from a point of connection 35 between the voltage dividing resistors is input to two Op-Amps 36, 38 serving as the input voltage (V1IN, V2IN). Based on the output voltage (V1OUT, V2OUT) obtained from the Op-Amps 36, 38, leakage occurrence is detected.
