Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling the temperature of electrochemical energy storage systems are slow to react to environmental changes and inefficient in utilizing temperature differences between multiple energy stores, leading to suboptimal heating and cooling operations.
Innovation Solution
A method that captures and compares the temperature and temperature control requirements of multiple electrochemical energy stores to control an air-conditioning apparatus, allowing for dynamic heating, cooling, and circulation strategies, including using one store's temperature to heat or cool another, and optimizing energy use by switching off when no requirements are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If temperature control is based on centralized monitoring only, then system complexity is reduced, but response speed to temperature changes is slow
Solution Approach 1:
The temperature monitoring system is segmented into multiple independent temperature sensors, each dedicated to a specific energy store. This allows each sensor to independently detect temperature changes in its associated energy store, enabling faster localized response without requiring complex centralized processing for each individual measurement.
Solution Approach 2:
The system implements feedback control by continuously monitoring temperatures via dedicated sensors and automatically adjusting the air-conditioning apparatus based on the captured temperature values and control requirements. This closed-loop feedback mechanism enables rapid response to temperature changes while maintaining systematic coordination through the control device.
2Use of energy by moving object
If each energy store is controlled independently, then response speed improves, but energy efficiency decreases due to ignoring temperature differences between stores
Solution Approach 1:
The system merges the temperature control functions of multiple energy stores by having the air-conditioning apparatus serve all stores simultaneously. The control device coordinates the operation based on temperatures from all stores, allowing the system to exploit temperature differences between stores for more efficient operation while maintaining rapid response through dedicated sensors for each store.
3Use of energy by moving object
If air-conditioning apparatus operates continuously, then temperature control reliability is maintained, but energy consumption increases
Solution Approach 1:
The air-conditioning apparatus operates dynamically rather than continuously. The control device adjusts the operation state (heating, cooling, circulation, or shutdown) based on real-time temperature values and control requirements from energy stores. This dynamic operation maintains temperature control reliability when needed while reducing energy consumption during periods when temperature control is not required.
