Solution Overview
Problem
Existing secondary battery supply systems cannot efficiently guide multiple power consumption elements to appropriate charging stations, leading to load concentration on specific stations.
Innovation Solution
A guide device and system that acquire and utilize battery information from both charging stations and power consumption elements to guide them to stations based on load balancing criteria, such as equalizing battery numbers or capacities across multiple stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user selects a charging station from information about multiple charging facilities, then the user can find a charging station, but the load concentrates on specific charging stations
Solution Approach 1:
The guide device acquires real-time battery information from multiple charging stations and uses this feedback to dynamically guide power consumption elements to appropriate stations. The system continuously monitors battery status at each station and adjusts guidance recommendations to balance the load across all stations, preventing concentration at any single location.
Solution Approach 2:
The system changes the parameter of station selection by considering multiple factors including battery information, station capacity, and current load status. Instead of simple proximity-based selection, the guide device evaluates and compares multiple parameters to determine the most appropriate charging station for each power consumption element, thereby distributing load more evenly.
2Productivity
If battery information is acquired from multiple charging stations to enable guidance, then load distribution improves, but system complexity increases
Solution Approach 1:
The guide device performs multiple functions: it acquires battery information from charging stations, monitors power consumption element status, makes guidance decisions, and provides recommendations. By consolidating these diverse functions into a single multi-functional system, the patent avoids the need for separate specialized systems for each function, thereby managing complexity while achieving load distribution.
3Productivity
If the guide device equalizes the number of batteries at multiple charging stations, then load concentration is avoided, but guidance precision requirements increase
Solution Approach 1:
The charging stations themselves provide battery information to the guide device, and the system uses this self-reported data to make equalization decisions. Each station monitors and reports its own battery status, reducing the need for external verification and simplifying the measurement precision requirements while still achieving effective load equalization.
