Battery Thermal Control Mode Switching for Charging Readiness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery temperature adjustment systems in vehicles lack efficient mechanisms to quickly adjust the temperature of power storage devices in response to user operations while ensuring optimal charging conditions are met at charging facilities.
Innovation Solution
A battery temperature adjustment system with two modes: navigation-triggered and operation-triggered, allowing the system to prioritize user-controlled temperature adjustments when necessary and maintain optimal charging conditions by integrating a cooling and heating device controlled by a processor to adjust the battery temperature based on the vehicle's travel route and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system automatically adjusts battery temperature based on navigation to charging facilities, then the battery temperature is optimized for charging arrival, but the system cannot quickly respond to user-initiated temperature adjustment requests
Solution Approach 1:
The system dynamically switches between two operational modes: automatic temperature adjustment mode (when navigation to charging facility is active) and manual temperature adjustment mode (when user operates temperature adjustment switch). This dynamic mode switching enables the system to adapt its control strategy based on user needs, allowing quick response to user operations while maintaining automatic optimization when appropriate
2Reliability
If the system prioritizes automatic temperature adjustment for charging optimization, then charging conditions are optimized, but user-initiated temperature adjustments are delayed or rejected
Solution Approach 1:
The system employs dynamic mode switching between automatic and manual temperature adjustment. When the user operates the temperature adjustment switch, the system transitions from automatic mode to manual mode, prioritizing user requests. This dynamic adaptation allows the system to maintain charging optimization reliability while becoming highly adaptable to user-initiated adjustments
Solution Approach 2:
The system provides self-service temperature adjustment by detecting user operations on the temperature adjustment switch and automatically transitioning to manual adjustment mode, enabling the system to serve user needs without requiring complex intervention or configuration
3Loss of energy
If the system maintains automatic temperature adjustment mode, then charging optimization is maintained, but additional power consumption occurs from unnecessary temperature adjustments
Solution Approach 1:
The system uses feedback from user operations on the temperature adjustment switch to determine when to activate manual mode. When users initiate temperature adjustment requests, the system receives this feedback and switches from automatic to manual mode, preventing unnecessary temperature adjustments and reducing energy loss while maintaining charging optimization when users do not intervene

AI summary
A battery temperature adjustment system includes a temperature adjustment device (800) and a processor (301). A setting mode of the temperature adjustment device (800) includes a first mode and a second mode. The first mode is a mode that is a setting in which, when a travel route of a vehicle (1) includes a facility where a power storage device (100) is chargeable, the temperature of the power storage device (100) is adjusted within a first temperature range. The second mode is a mode that is a setting in which a temperature of the power storage device (100) is adjusted within a second temperature range in response to reception of a predetermined operation. The processor (301) is configured to control the temperature adjustment device (800) and to maintain the second mode when the setting mode is the second mode and the travel route includes the facility.
