Battery Capacity Allocation for Dynamic Secondary User Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery management systems for electric vehicles do not effectively utilize the battery capacity by fixing the users of the virtually divided battery capacity, lacking the ability to dynamically select another user based on desired use conditions.
Innovation Solution
A battery management system that virtually divides the battery capacity into two areas, one for the vehicle user and another for a secondary user, allowing for dynamic selection of the secondary user based on desired use conditions such as payment amount or usage period, through a communication unit and recognition section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery capacity is virtually divided into fixed areas for first user and second user, then the battery management system is simple to operate, but the battery utilization efficiency is low because another user cannot be selected dynamically
Solution Approach 1:
The patent transforms the fixed user allocation into a dynamic selection mechanism. The battery management system now dynamically selects another user based on desired use conditions such as payment amount and usage period, rather than having predetermined fixed allocations. This dynamic approach resolves the contradiction by maintaining operational simplicity through automated selection while significantly improving battery utilization efficiency through competitive bidding.
Solution Approach 2:
The patent introduces selectable parameters (payment amount, usage period) that change based on different prospective users' offers. The system evaluates multiple parameter combinations from different users and selects the optimal allocation, thereby improving battery utilization without complicating the core management function through automated parameter comparison and selection.
2Productivity
If the system dynamically selects another user based on desired use conditions, then the battery utilization efficiency is improved, but the device complexity increases due to additional communication and recognition sections
Solution Approach 1:
The patent implements multi-functional components that handle multiple tasks. The communication unit serves both to notify users of battery availability and to receive desired use condition information from prospective users. The desired use condition recognition section both receives and evaluates multiple parameters (payment amount, usage period) simultaneously. This multi-functionality approach improves battery utilization while minimizing the increase in device complexity by making existing components do more work.
Solution Approach 2:
The patent merges the communication functions and recognition functions into integrated sections rather than separate independent systems. The communication unit and recognition section work as a unified subsystem to handle user selection, reducing overall system complexity while enabling dynamic user selection and improving battery utilization efficiency.
3Device complexity
If the battery capacity is allocated to a fixed second user, then the system complexity is low, but the adaptability to different use conditions is limited
Solution Approach 1:
The patent makes the user allocation dynamic rather than fixed. The system adapts to different use conditions by selecting another user based on received desired use conditions, thereby achieving high adaptability while maintaining relatively simple system structure through automated decision-making processes.
Solution Approach 2:
The patent enables the system to adapt to different use conditions by evaluating multiple parameters (payment amount, usage period) from prospective users. The allocation decisions change based on these parameters, providing versatility in handling different scenarios while keeping the system structure manageable through standardized evaluation criteria.

AI summary
A battery management system includes: a battery capacity division section that virtually divides a capacity of a battery mounted on a mobile object into a first area and a second area, and makes the battery available to a first user within the first area and makes the battery available to a second user within the second area; a desired use condition recognition section that receives, via a communication unit, desired use condition information presenting a desired condition for use of the battery within the second area and recognizes the desired condition for use, the desired use condition information being transmitted from a prospective user terminal used by a prospective user of the battery; and a battery user selection section that, when the desired condition for use satisfies a predetermined condition for selection, selects, as the second user, the prospective user of the battery presenting the desired condition for use that satisfies the condition for selection.
