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.
