Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electric vehicles experience anxiety about insufficient battery power, leading to potential overcharging and battery deterioration due to frequent adjustments of the target remaining capacity set by existing charging control systems.
Innovation Solution
A charging control method that sets the target remaining capacity through user input during initial charging and adjusts it downward based on usage patterns, preventing revocation of settings and reducing user anxiety while avoiding overcharging and battery deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the target remaining capacity is set to prevent deep discharge and ensure necessary power for the following trip, then battery deterioration is restricted and reliable power supply is ensured, but users feel anxious about insufficient remaining capacity and may revoke settings or increase charging amount
Solution Approach 1:
The charging control apparatus dynamically adjusts the target remaining capacity based on accumulated usage data and learned user patterns. The system transitions from static user-defined settings to adaptive dynamic control, automatically modifying charging parameters to balance battery protection with user comfort, thereby preventing setting revocation while maintaining reliability.
Solution Approach 2:
The system implements feedback by monitoring user charging behavior and usage patterns, then using this information to automatically adjust the target remaining capacity. The feedback loop learns from user responses to previous charging suggestions and refines future recommendations, improving user acceptance while maintaining battery protection without requiring manual setting adjustments.
2Ease of operation
If users increase charging amount beyond necessary to eliminate anxiety about power insufficiency, then user worry is reduced, but battery experiences overcharge state and deterioration is promoted
Solution Approach 1:
The charging control apparatus performs self-service by automatically managing the target remaining capacity without requiring user intervention. The system independently monitors usage patterns, calculates appropriate charging targets, and executes charging control, thereby protecting the battery from overcharge while eliminating the need for users to manually adjust settings or understand charging parameters.
Solution Approach 2:
The system changes the target remaining capacity parameter dynamically based on accumulated usage data and user behavior patterns. Instead of using a fixed or user-defined parameter, the system automatically adjusts this critical parameter to optimize both battery protection and user comfort, preventing overcharge while maintaining adequate power levels.
3Duration of action of stationary object
If the target remaining capacity is set low to prevent battery deterioration, then battery life is extended, but users perceive insufficient remaining capacity and experience anxiety
Solution Approach 1:
The system performs preliminary action by proactively adjusting the target remaining capacity before user anxiety can manifest. By anticipating user needs based on usage patterns and pre-calculating appropriate charging targets, the system ensures adequate power levels are maintained while still protecting the battery, preventing the perception of insufficient capacity before it occurs.
Solution Approach 2:
The target remaining capacity transitions from a static low value to a dynamic parameter that adapts to user needs and usage patterns. The system dynamically balances battery protection with user satisfaction by adjusting the target capacity based on real-time data, ensuring the battery is protected while users perceive adequate power availability.

AI summary
A charging control method of an electric moving body that moves using a battery as a power source. A target remaining capacity is set through a user when initial charging of the battery is performed, and the target remaining capacity is set in a manner to decrease every time the battery is charged, based on a usage situation of the battery of the electric moving body by the user.
