摘要:
A power supply device mounted to a hybrid vehicle (100) includes: a capacitor (C1) that is chargeable/dischargeable; an electric power input/output unit (40) for inputting/outputting electric power between the capacitor (C1) and a charge/discharge device (50) installed external to the hybrid vehicle (100); a temperature sensor (21) detecting a temperature (Tc) of the capacitor (C1); and a control device (30) increasing the temperature of the capacitor (C1) by performing at least one of charging from the charge/discharge device (50) to the capacitor (C1) and discharging from the capacitor (C1) to the charge/discharge device (50) when the control device (30) determines based on a detection result of the temperature sensor (21) that the temperature of the capacitor (C1) is required to be increased. Thereby, the temperature of the capacitor (C1) can be increased without causing a load such as an inverter (14, 15) to consume electric power.

A power storage device (CA) is in parallel to a battery (B), and is connected to a power supply line (PL1) and a ground line (PL2). A service plug (SVP) internally includes a resistance (R2) and is attached to the power storage device (CA) for connecting the resistance (R2) between contacts of a relay circuit (RL1). The service plug (SVP) is a member independent of an ordinary service plug arranged at the power storage device (CA). When residual charges in the power storage device (CA) are substantially zero, an operator appropriately attaches the service plug (SVP) to the power storage device (CA) in place of the ordinary service plug. Accordingly, when the power storage device (CA) enters an overdischarged state due to a maintenance or the like of the power storage device (CA), a vehicle system to which the service plug (SVP) internally having a current limiting device is attached is started so that occurrence of a rush current can be prevented.

In response to detection of connection between a power supply outside a vehicle and a charge plug (S10), control device invalidates key verification performed for determining whether a key of a user is regular or not (S40), when a shift position is parking and a parking brake is active. This satisfies system start conditions, and the control device turns on respective relays to start a system (S50), and executes charge control for charging a power storage device from the power supply outside the vehicle (S60).

A power supply system for driving a vehicle includes a battery (B), a boost converter (12) boosting the voltage of the battery (B), a capacitor (40) to which the voltage boosted by the boost converter (12) is applied across the electrodes, system main relays (C-SMRP, C-SMRG) provided between the capacitor (40) and the output of the boost converter (12) for connection and disconnection between the capacitor (40) and the boost converter (12), and a control device (30) controlling the boost converter (12) and the system main relays (C-SMRP, C-SMRG). The control device (30), after giving an instruction for disconnection to the system main relays (C-SMRP, C-SMRG), causes the boost converter (12) to change the voltage of the output to determine whether the system main relays (C-SMRP, C-SMRG) are normally disconnected.

Provided is a plug wherein a plurality of points in an electric circuit can be easily put into a conductive state or a nonconductive state. A system wherein such a plug is applied is also provided. The composite plug is provided with a plurality of plugs, each of which is provided with two conductive pieces connected by a conductive member. A current is carried between the two circuit terminals when the two conductive pieces are brought into contact with two circuit terminals included in the electric circuit, respectively. A current is not carried between the two circuit terminals when the two conductive pieces are separated from the two circuit terminals included in the electric circuit, respectively. The plugs are attached to a common case body.

An ECU executes a program including the steps of: calculating regenerative power value P based on a brake pressure (S100); calculating limit charging power WIN(B) to a battery (S102); calculating limit charging power WIN(C) to a capacitor (S104); when it is determined that regenerative power value P is larger than the sum of WIN(B) and WIN(C) (YES at S106), estimating (S 108) that a large regenerative energy sufficient to fully charge the capacitor even if the battery is charged with priority would be generated; and transmitting a control signal (S110) to set output voltage of a boost converter to be not higher than the voltage of the capacitor so as to charge the battery with priority.

A cooling device (40) is provided with a cooling fan (F10) arranged on the side of an electrical storage device (C1), an exhaust port (44) arranged on the side of a battery (B), and a cooling wind flow channel for permitting cooling wind from the cooling fan (F10) to flow. As for the electrical storage device (C1) and the battery (B), a space inside the case (50) communicates with a space inside a case (52) by an opening section (46). Cooling wind supplied from the air blowing fan (F10) circulates through the space formed inside the case (50) of the electrical storage device (C1) and cools capacitor cells (CC1-CC5). When the cooling wind passed through the electrical storage device (C1) is introduced into a case (52) of the battery (B) through an opening section (46), the cooling wind cools the battery cells (BC1-BC6) by circulating in a space between the upper surface of the battery cells (BC1-BC6) and the case (52) and spaces between the battery cells. Then, the cooling wind is discharged to the external of the case (52) through the exhaust port (44).
