Solution Overview

Problem

Recreational vehicle air conditioners consume high power, exceeding the limited battery capacity, leading to potential shutdowns during extended use, affecting user experience.

Innovation Solution

A method to control air conditioner operation by calculating and adjusting maximum power based on set duration and battery charge, continuously monitoring and recalculating power to ensure operation within battery limits, using a controller to implement these adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the air conditioner operates at high power to provide comfortable cooling, then the cooling effect is improved, but the battery charge depletes too quickly, causing the air conditioner to shut down before the desired duration

Engineering Contradiction:
Improvecooling effectVSAvoidoperating duration
Core Design Contradiction:
TemperatureVSDuration of action of moving object

Solution Approach 1:

The air conditioner dynamically adjusts its operating power based on real-time battery charge levels and remaining operating duration. The controller continuously monitors battery charge and recalculates the maximum operating power, allowing the system to adapt its cooling capacity to available energy resources, thereby preventing shutdowns while maintaining comfortable operation within energy constraints

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operating power parameter based on battery charge state. By calculating the maximum operating power as a function of remaining charge and desired duration, the air conditioner adjusts its power consumption parameter to ensure it can complete the full operating cycle without depletion, resolving the contradiction between high power cooling and sufficient duration

Inventive Principle:
Principle #35Parameter changes

2Power

If the air conditioner operates continuously at maximum power, then the cooling performance is maintained, but the battery charge is insufficient to support the full set operating duration

Engineering Contradiction:
Improvecooling powerVSAvoidenergy consumption
Core Design Contradiction:
PowerVSUse of energy by moving object

Solution Approach 1:

Before the air conditioner operates, the controller pre-calculates the maximum operating power based on the current battery charge and the desired operating duration. This preliminary calculation ensures that the air conditioner is configured with the correct power level from the start, preventing both premature shutdowns and unnecessary energy consumption, as the system begins operation already optimized for the available energy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback by monitoring the battery charge level during operation and recalculating the maximum operating power in real-time. This feedback mechanism allows the air conditioner to adjust its power consumption based on actual battery status, ensuring optimal energy utilization throughout the operating duration while maintaining adequate cooling performance

Inventive Principle:
Principle #23Feedback

AI summary

A control method includes obtaining an operating instruction including a set operating duration, determining a first maximum operating power of an air conditioner of a vehicle according to the set operating duration and a current remaining charge of a battery of the vehicle, controlling the air conditioner to operate in a power range not exceeding the first maximum operating power, recording a continuous operating duration of the air conditioner and obtaining a real-time remaining charge of the battery, determining a second maximum operating power of the air conditioner according to the continuous operating duration and the real-time remaining charge, and controlling the air conditioner to continue operating in a power range not exceeding the second maximum operating power.
