Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery management systems for electric vehicles do not efficiently manage battery power resources in an economic fashion, particularly due to the variability of electricity prices, which can affect the cost of charging and discharging batteries.
Innovation Solution
A system and method that includes a server and mobile terminal configured to acquire and provide real-time electricity pricing information, allowing users to instruct the battery management device to charge or discharge the battery based on current prices, thereby optimizing energy usage and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If real-time electricity pricing information is integrated into the battery management system, then economic efficiency of battery charging/discharging is improved, but system complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary component that handles the complex tasks of acquiring real-time electricity pricing information and processing charging/discharging decisions. The server receives pricing data from external sources, processes it according to user preferences and battery status, and sends control instructions to the battery management device. This intermediary approach allows the economic efficiency improvement to be achieved without significantly increasing the complexity of the local battery management system.
Solution Approach 2:
The server performs multiple functions including acquiring electricity pricing information, storing user preferences, processing charging/discharging decisions, and communicating with both the battery management system and power grid. By consolidating these diverse functions in a single multi-functional server, the system avoids the need for multiple separate complex components, thus improving economic efficiency while limiting the increase in overall system complexity.
2Ease of operation
If manual monitoring and control of battery charging/discharging is implemented, then operational simplicity is maintained, but economic benefits are reduced due to inability to respond to real-time price changes
Solution Approach 1:
The system enables automatic charging and discharging operations by having the server autonomously monitor electricity pricing information and execute charging/discharging decisions based on pre-configured user preferences and real-time price signals. Once users set their preferences, the system operates automatically without requiring continuous manual intervention, thus maintaining operational simplicity while capturing economic benefits through real-time price-responsive behavior.
Solution Approach 2:
The system implements a feedback loop where the server continuously monitors electricity pricing information, compares it against user preferences and battery status, and automatically adjusts charging/discharging operations accordingly. This automated feedback mechanism allows the system to respond dynamically to real-time price changes without requiring manual user input, thereby maintaining ease of operation while maximizing economic benefits through timely price-responsive decisions.
