Remote Air Conditioning Control for EV Battery Range Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively prevent the remaining battery charge from becoming insufficient while a vehicle is traveling, especially when remote air conditioning is in use.
Innovation Solution
An information processing device that acquires information about the travel distance required for a vehicle and operates remote air conditioning only when the remaining battery charge is sufficient for that distance, stopping the air conditioning when the charge falls below a certain threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote air conditioning is operated to improve user comfort, then the air conditioning function is provided, but the remaining battery charge becomes insufficient
Solution Approach 1:
The control unit calculates the required battery charge amount before operating remote air conditioning by acquiring travel distance information and estimating power consumption. This preliminary calculation ensures that the battery has sufficient charge reserves before the air conditioning operation begins, preventing charge depletion during travel
Solution Approach 2:
The control unit continuously monitors the battery charge amount during remote air conditioning operation and compares it against the calculated required charge amount. When the remaining charge approaches the required amount, the system provides feedback to stop the air conditioning operation, ensuring the battery maintains sufficient charge for travel
2Ease of operation
If remote air conditioning is operated without charge consideration, then user comfort is improved, but the vehicle may be stranded due to insufficient battery charge
Solution Approach 1:
The control unit performs preliminary calculations of travel distance and required battery charge before permitting remote air conditioning operation. This advance planning ensures that the vehicle maintains sufficient charge reserves for travel, preventing the vehicle from being stranded
Solution Approach 2:
The control unit continuously monitors battery charge levels during air conditioning operation and provides real-time feedback to stop operation when charge levels approach critical thresholds. This feedback mechanism maintains reliable battery charge levels throughout the operation, ensuring vehicle travel reliability

AI summary
A control unit configured to execute: acquiring information on a first distance, which is a travel distance required for a vehicle; activating remote air conditioning in response to a request to activate remote air conditioning of the vehicle and a remaining charge amount of a battery of the vehicle being greater than a first remaining amount, which is a remaining charge amount of a battery capable of traveling the first distance; and deactivating remote air conditioning in response to the remaining charge amount of the battery becoming equal to or less than the first remaining amount during operation of the remote air conditioning.
