Battery Management Device for Profit Segmentation in Power Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle secondary batteries deteriorate over time, making them unsuitable for electric vehicles, and existing methods for reusing them are inefficient, as they require disassembly and struggle to balance operator and user profits in power exchange businesses.
Innovation Solution
A management device and method that connects secondary batteries to a power network for stationary use, managing power distribution between operators and users, adjusting profit returns based on battery deterioration and usage history, allowing for efficient reuse of deteriorated batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the in-vehicle secondary battery is transferred to a user as is for stationary use, then the reuse process becomes simpler and faster, but it is difficult to adjust profit between the operator and the user
Solution Approach 1:
The patent segments the power from the secondary battery into two distinct parts: power used by the operator for power exchange business and power used exclusively by the user for stationary use. This segmentation enables independent management and profit calculation for each party, resolving the difficulty in profit adjustment while maintaining the simplicity of transferring the battery as-is.
Solution Approach 2:
The management device acts as an intermediary between the operator and the user, managing the power from the secondary battery and calculating profit distribution. This intermediary system automatically handles the complex profit adjustment calculations, making the process transparent and fair without requiring manual intervention or complex negotiations between parties.
2Ease of operation
If the battery pack is disassembled to reuse the in-vehicle secondary battery, then profit adjustment between operator and user becomes possible, but the process takes more time and effort
Solution Approach 1:
The patent extracts the essential function needed for profit adjustment - the ability to separate and manage power usage - without requiring physical disassembly of the battery pack. The management system extracts and tracks power consumption data for operator and user separately, achieving the profit adjustment capability while keeping the battery pack intact.
3Productivity
If the secondary battery is used for power exchange business, then operator profit increases, but the user may not have sufficient power available for stationary use
Solution Approach 1:
The patent segments the total power capacity of the secondary battery into operator-usable power and user-guaranteed power. This segmentation ensures that a minimum amount of power is reserved for the user's stationary needs, while the remaining power can be utilized by the operator for power exchange business, thus balancing both interests.
Solution Approach 2:
The management device dynamically adjusts the allocation parameters of power between operator and user based on battery state of charge, usage patterns, and business needs. This parameter adjustment mechanism ensures sufficient power availability for users while maximizing operator profit opportunities from power exchange activities.

AI summary
A management device includes a manager configured to manage power stored in a secondary battery provided to a user for stationary use and execute a power exchange business, the power exchange business being performed by connecting the secondary battery to a power network, and a deriver configured to derive return information for returning part of a profit obtained through the power exchange business to the user.
