Vehicle power management system
A vehicle power management system includes a battery, an air conditioner driven by power of the battery, an external power supply device that enables external power supply where the power of the battery is supplied to an external electric device, and a determination unit. The determination unit determines whether an operation restriction of an air conditioner is executed during the external power supply. The determination unit determines that the operation restriction is executed when all of following four conditions are satisfied: (A-1) a target blowout temperature is less than a predetermined blowout threshold temperature during cooling; (A-2) an outside air temperature exceeds a predetermined outside air threshold temperature during cooling; (A-3) a refrigerant temperature after heat is exchanged with an air blown into the vehicle cabin exceeds a predetermined refrigerant threshold temperature during cooling; and (A-4) a blower air volume of the air conditioner exceeds a predetermined threshold air volume.
1. A vehicle power management system comprising:
a battery installed in a vehicle;
an air conditioner for a vehicle cabin, the air conditioner being driven by power of the battery;
an external power supply device that enables external power supply in which the power of the battery is supplied to an external electric device; and
a determination unit that determines whether an operation restriction of the air conditioner is executed during the external power supply, wherein the determination unit determines that the operation restriction is executed when all of following four conditions are satisfied, regarding a cooling operation state of the air conditioner, as determination of whether the operation restriction is executed:
(A-1) a target blowout temperature is less than a predetermined blowout threshold temperature during cooling;
(A-2) an outside air temperature exceeds a predetermined outside air threshold temperature during cooling;
(A-3) a refrigerant temperature after heat is exchanged with an air blown into the vehicle cabin exceeds a predetermined refrigerant threshold temperature during cooling; and
(A-4) a blower air volume of the air conditioner exceeds a predetermined threshold air volume.
2. The vehicle power management system according to claim 1 , wherein the determination unit determines whether the operation restriction is executed when a state of charge of the battery is less than a predetermined battery determination threshold.
3. The vehicle power management system according to claim 1 , wherein when the determination unit outputs determination for executing the operation restriction, the air conditioner closes an outside air introduction port for an entire period in which the operation restriction is executed.
4. The vehicle power management system according to claim 1 , wherein when the determination unit outputs determination for executing the operation restriction, the air conditioner invalidates an outside air introduction command by an input operation from an air conditioning operation panel inside the vehicle for an entire period in which the operation restriction is executed.
5. A vehicle power management system comprising:
a battery installed in a vehicle;
an air conditioner for a vehicle cabin, the air conditioner being driven by power of the battery;
an external power supply device that enables external power supply in which the power of the battery is supplied to an external electric device; and
a determination unit that determines whether an operation restriction of the air conditioner is executed during the external power supply, wherein the determination unit determines that the operation restriction is executed when all of following four conditions are satisfied, regarding a heating operation state of the air conditioner, as determination of whether the operation restriction is executed:
(B-1) a target blowout temperature exceeds a predetermined blowout threshold temperature during heating;
(B-2) an outside air temperature is less than a predetermined outside air threshold temperature during heating;
(B-3) a refrigerant temperature after heat is exchanged with an air blown into the vehicle cabin is less than a predetermined refrigerant threshold temperature during heating; and
(B-4) a blower air volume of the air conditioner exceeds a predetermined threshold air volume.
6. The vehicle power management system according to claim 5 , wherein the determination unit determines whether the operation restriction is executed when a state of charge of the battery is less than a predetermined battery determination threshold.
7. The vehicle power management system according to claim 5 , wherein when the determination unit outputs determination for executing the operation restriction, the air conditioner closes an outside air introduction port for an entire period in which the operation restriction is executed.
8. The vehicle power management system according to claim 5 , wherein when the determination unit outputs determination for executing the operation restriction, the air conditioner invalidates an outside air introduction command by an input operation from an air conditioning operation panel inside the vehicle for an entire period in which the operation restriction is executed.
