摘要： A power supply system includes: a voltage converter that converts a voltage between first and second power circuits; a power controller that controls charging and discharging of first and second batteries; a cooling output controller that controls cooling output for the second battery; a temperature remaining-capacity acquirer that acquires a temperature remaining-capacity T2_mar; and a cooling remaining-capacity acquirer that acquires a cooling remaining-capacity PC2_mar depending on a difference between maximum cooling output and the cooling output of the second cooler. The power controller is configured to stop the voltage converter in a case where at least one of the temperature remaining-capacity T2_mar and the cooling remaining-capacity PC2_mar is less than an associated one of a threshold value for the temperature remaining-capacity and a threshold value for the cooling remaining-capacity and a potential difference between the first and second batteries is equal to or more than a potential difference threshold value.

摘要： A power supply system for a vehicle includes a management ECU that controls output power of first and second batteries in a normal mode or an output priority mode, first cooler that cools the first battery, a second cooler that cools the second battery, and a cooling circuit ECU that controls first and second cooling output of the coolers. In a case where an operation mode of the management ECU is the output priority mode and the first battery has a cooling remaining-capacity, the cooling circuit ECU increases the first cooling output as compared with a case where the operation mode is the normal mode. In a case where the operation mode is the output priority mode and the second battery has a cooling remaining-capacity, the cooling circuit ECU increases the second cooling output as compared with the case where the operation mode is the normal mode.

摘要： A power supply system includes: a capacitive first battery; an output-type second battery having a smaller heat capacity than the first battery; a voltage converter that converts a voltage between first and second power circuits; a power converter that converts power between the first power circuit and a drive motor; and a power controller that operates the voltage converter and the power converter. The power controller is configured to: after a start of operation, execute a power pass control under which power is transferred between the first and second batteries, until a total output upper limit Ptot_max of all the batteries exceeds a travelable threshold value Pready1; and subsequent to the power pass control, execute a second priority control under which the second battery is discharged in preference to the first battery, until a first output upper limit P1_max of the first battery exceeds a margin traveling threshold value Pready2.

摘要： A power supply system includes a first battery module 21, a second battery module 31, a first maintenance plug 7 that, when detached from the first battery module 21, isolates the first battery module 21 from a power circuit 5, a second maintenance plug 8 that, when detached from the second battery module 31, isolates the second battery module 31 from the power circuit 5, and a locking mechanism that locks the second maintenance plug 8. The first maintenance plug 7 includes an unlocking key for unlocking the second maintenance plug 8 locked by the locking mechanism.

摘要： A battery unit includes at least one battery module, a cooling device configured to deliver a cooling gas configured to cool the battery module to the battery module, and a junction board mounted with a wiring component configured to electrically connect the battery module and an external device and allow a charging power and/or a discharging power of the battery module to flow. The junction board is disposed above the cooling device at a position where at least a part of the junction board overlaps the cooling device when viewed from an upper-lower direction.

摘要： A power supply system includes: power circuits that connect first and second batteries to a load circuit; a power controller that controls output power of the first and second batteries; and an allowable output upper limit acquirer that acquires a first allowable output upper limit P1_lim of the first battery and a second allowable output upper limit P2_lim of the second battery. The power controller is configured to switch, based on battery temperatures T1 and T2, a battery output control mode between a first priority output mode in which the output power of the first battery is increase to the first allowable output upper limit P1_lim in preference to that of the second battery and a second priority output mode in which the output power of the second battery is increased to the second allowable output upper limit P2_lim in preference to that of the first battery.

摘要： A battery unit mounted on a vehicle includes a base plate, and a battery module which is fixed to the base plate and in which a plurality of battery cells are stacked. A flow path is formed between the base plate and the battery module. The base plate is provided with a first suspension member which crosses the flow path and forms a part of the flow path, and a second suspension member which extends above the first suspension member.

摘要： The battery cooling structure includes a cell stacked body that has an inter-cell flow path between adjacent battery cells, a base plate that is disposed adjacent to one of surfaces of the cell stacked body, an inflow-side flow path that is disposed between the cell stacked body and the base plate and communicates with the inter-cell flow path, and an air supply port that is disposed in one end portion of the inflow-side flow path in the stacking direction and supplies air to the inflow-side flow path are included. The base plate has a branching portion that branches air in the inflow-side flow path, into a plurality of flows, and the branching portion is disposed at a position that is further from the air supply port than one endmost battery cell of the cell stacked body, the one endmost battery cell being adjacent to of the air supply port.
