摘要:
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.

When a determination is made that a signal transmitted by a voltage sensor (180), a voltage sensor (182), a current sensor (192), a temperature sensor (193), a temperature sensor (194), a first CPU (310), a second CPU (320) and a communication circuit (350) is in error, a third CPU (330) of a motor generator ECU (172) determines that the control system is in error. When a determination is made that the control system is in error, the third CPU (330) determines whether each of the voltage sensor (180), voltage sensor (182), current sensor (192), temperature sensor (193), temperature sensor (194), first CPU (310), second CPU (320) and communication circuit (350) is in error or not.
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.
摘要:
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).
摘要:
A cooling device (40) includes a cooling fan (F10) placed in a power storage device (C1), an exhaust port (44) placed in a battery (B), and a cooling wind flow path for allowing cooling wind taken in from the cooling fan (F10) to flow therethrough. In the power storage device (C1) and the battery (B), communication between a gap inside a casing (50) a gap inside a casing (52) can be established via an opening (46). The cooling wind supplied from the wind blowing fan (F10) flows through the gap formed inside the casing (50) for the power storage device (C1) to cool capacitor cells (CC1-CC5). Subsequently, the cooling wind that has passed through the power storage device (C1) is introduced into the inside of the casing (52) for the battery (B) via the opening (46), and flows through a gap between the upper surface of battery cells (BC1-BC6) and the casing (52) and a gap between the battery cells to cool the battery cells (BC1-BC6). Thereafter, the cooling wind is emitted to the outside of the casing (52) via the exhaust port (44).
摘要:
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.
摘要:
A maximum current Imax is calculated on the basis of an open-circuit voltage Voc, a lower limit voltage Vcapmin, and an internal resistance Rcap of a capacitor and a first maximum output Wcouttmp1 is calculated on the basis of the maximum current Imax and the lower limit voltage Vcapmin (S230, S240). A second maximum output Wcouttmp2 is calculated on the basis of the open-circuit voltage Voc and an open-circuit lower limit voltage Vocmin (S250). A third maximum output Wcouttmp3 is calculated on the basis of a capacitor voltage Vcap and the lower limit voltage Vcapmin (S260). A smallest value among the calculated three maximum outputs is set as an execution maximum output Wcout of the capacitor (S270). A motor is controlled to be driven in a range of this execution maximum output Wcout.
