Vehicle air conditioning device

A vehicle air conditioning device which conditions air of a vehicle interior, comprising:

• a compressor to compress a refrigerant;
• an indoor heat exchanger to perform exchange of heat between air supplied to the vehicle interior and the refrigerant;
• an outdoor heat exchanger disposed outside the vehicle interior;
• and
• a control device,
• wherein the vehicle air conditioning device includes an equipment temperature adjusting device to adjust a temperature of an object of temperature regulation mounted in a vehicle,
• wherein the control device controls the equipment temperature adjusting device based on a gradient of a change in an index indicating the temperature of the object of temperature regulation,
• wherein the equipment temperature adjusting device is capable of cooling the object of temperature regulation by using the refrigerant,
• wherein when a rise rate ΔT of the index indicating the temperature of the object of temperature regulation is greater than or equal to a predetermined value A1, the control device starts cooling of the object of temperature regulation by the equipment temperature adjusting device,
• wherein the object of temperature regulation is a battery capable of charging from outside, and
• wherein the control device sets the predetermined value A1 at the time of charging to the battery as follows:
• A1=(TUL−Tam)/charging completion time, or
• A1=(TUL−T0)/charging completion time,
• where the TUL is an upper limit value of an index indicating a temperature of the battery, the Tam is an outdoor air temperature, the T0 is a value of an index indicating a temperature of the battery at the start of charging, and the charging completion time is a time from the charging start time of the battery to the completion of charging of the battery.
