摘要:
There is provided a power supply control device 10 which can determine a deterioration state of a sub-battery 30 appropriately and determine permission/prohibition of running of a vehicle based on the result of deterioration determination. The power supply control device 10 has a first power supply 16, a second power supply 30 composed of a secondary battery, a DC/DC converter 14 which converts a voltage of the first power supply 16 and enables the second power supply 30 to be charged with the converted output voltage, and a controller 31 which controls the DC/DC converter 14 and determines deterioration of the second power supply 30. The controller 31 controls the DC/DC converter 14 during a charge period so that the output voltage value of the DC/DC converter 14 is greater than or equal to a predetermined voltage value, to thereby charge the second power supply 30, controls the DC/DC converter during a predetermined discharge period after the charge period so that the output voltage value of the DC/DC converter 14 is less than the predetermined voltage value, to thereby discharge the second power supply 30, and determines deterioration of the second power supply 30 according to a state of charge of the second power supply 30 after the discharge period.
摘要:
In the event of collision of a vehicle (100), a control device (300) for a power converting apparatus (200) in the vehicle (100) is supplied with a power source voltage for operations thereof, using electric power resulting from residual charges accumulated in smoothing capacitors (C1, C2) provided in the power converting apparatus (200). With such a configuration, even if a power source voltage for the control device (300) is not supplied from outside the power converting apparatus (200) due to disconnection of a line, the residual charges accumulated in the smoothing capacitor (C1, C2) provided in the power converting apparatus (200) can be discharged.
摘要:
A drive device for a vehicle includes a motor generator generating drive force, and a power control unit (PCU) (21) provided integrally with the motor generator for controlling the motor generator. The PCU (21) includes a low-voltage circuit section (71) to which a relatively low voltage is applied, a high-voltage circuit section (75) which is located at a rear side of the vehicle relative to the low-voltage circuit section (71) and to which a relatively high voltage is applied, and a cooling plate (72) located between the low-voltage circuit section (71) and the high-voltage circuit section (75) in a longitudinal direction of the vehicle for cooling the high-voltage circuit section (75). With such configuration, the drive device for a vehicle allows the power control unit to be protected appropriately against an externally imposed shock.
