Battery Charging Reward Control for Recommended State of Charge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slow charging times increase when performing slow charging, which affects energy efficiency in mobility vehicles equipped with secondary batteries.
Innovation Solution
A reward providing device and method that acquires battery state-of-charge information when charging is complete and provides rewards to users when the battery state is at or below a recommended upper limit charge, set lower than full charge, to encourage shorter charging times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If slow charging is performed to ensure battery safety and extend battery life, then battery reliability is improved, but charging time increases
Solution Approach 1:
The patent applies partial action by charging the battery only to a recommended upper limit state of charge (less than full charge) rather than charging to 100%. This partial charging approach prevents overcharging damage and extends battery life while significantly reducing charging time. The system deliberately does not perform the complete action (full charging) but rather a partial action that achieves the essential purpose (sufficient power supply) with fewer negative consequences.
Solution Approach 2:
The patent changes the state of charge parameter from the conventional full charge (100%) to a recommended upper limit (less than full charge). This parameter change optimizes the balance between battery reliability and charging time by identifying that full charge is not necessary for most applications and that charging to a lower state reduces stress on the battery, thereby extending its lifespan while saving time.
2Duration of action of moving object
If users charge batteries to full capacity to maximize usage time, then operational duration is improved, but energy efficiency deteriorates due to extended charging time
Solution Approach 1:
The patent applies partial action by providing rewards for charging to a recommended upper limit rather than full capacity. This encourages users to perform partial charging (sufficient for most needs) instead of excessive charging (to 100%), thereby improving energy efficiency by reducing the time batteries spend in high-stress charged states while still providing adequate operational duration for typical use cases.
Solution Approach 2:
The patent introduces feedback through a reward system that provides positive reinforcement to users for charging behavior that improves energy efficiency. The reward mechanism creates a feedback loop where users receive recognition or benefits for charging to the recommended level, gradually changing user behavior patterns to align with energy-efficient practices while maintaining satisfactory operational duration.

AI summary
A reward providing device comprises an acquiring section that acquires, when charging of the battery by a charging device is completed, battery state-of-charge information concerning a battery state of charge that is a state of charge of a battery provided to a moving body, and a reward providing section that provides a reward to the user of the moving body when the battery state of charge is less than or equal to a recommended upper limit state of charge that is an upper limit of a recommended charge rate set to be lower than a full charge, serving as a state of charge that is recommended.
