VEHICLE POWER MANAGEMENT SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17971068 titled 'VEHICLE POWER MANAGEMENT SYSTEM

Simplified Explanation

The abstract describes a vehicle power management system that includes a battery, an air conditioner driven by the battery power, an external power supply device, and a determination unit. The determination unit determines whether to restrict the operation of the air conditioner during external power supply based on certain conditions being met.

• The system includes a battery, air conditioner, external power supply device, and determination unit.
• The determination unit decides if the air conditioner operation should be restricted during external power supply.
• The operation restriction is determined based on four conditions being satisfied.
• The conditions include the target blowout temperature, outside air temperature, refrigerant temperature, and blower air volume.

Potential applications of this technology:

• Vehicle power management systems in electric or hybrid vehicles.
• Efficient use of battery power for air conditioning while supplying power to external devices.

Problems solved by this technology:

• Ensures optimal use of battery power in vehicles.
• Prevents excessive power consumption by the air conditioner during external power supply.

Benefits of this technology:

• Maximizes the efficiency of battery power usage.
• Reduces the strain on the battery during external power supply.
• Improves overall energy management in vehicles.

Original Abstract Submitted

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.
