Battery Preconditioning Mode Priority for Charging Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery temperature adjustment systems face inefficiencies in balancing user-operated and navigation-based temperature controls, leading to unnecessary power consumption and suboptimal charging conditions.
Innovation Solution
A battery temperature adjustment system with dual modes: navigation-triggered and operation-triggered settings, where the processor prioritizes or maintains the navigation-triggered mode to ensure the battery is at an optimal charging temperature upon arrival, rejecting user-operated adjustments during navigation-triggered mode to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the temperature adjustment device operates in the first mode (navigation-triggered) to automatically adjust battery temperature within a first temperature range suitable for charging, then the battery temperature is optimized for charging at the time of arrival at the charging facility, but the system cannot respond to user-operated temperature adjustment requests within a second temperature range
Solution Approach 1:
The system dynamically switches between two operational modes: the first mode (navigation-triggered automatic adjustment) and the second mode (user-operated adjustment). The processor determines which mode to activate based on whether navigation to a charging facility is triggered, allowing the system to adapt its temperature control behavior to different usage scenarios and balance automated optimization with user control needs
2Ease of operation
If the system accepts user operations for temperature adjustment within the second temperature range, then user preferences can be accommodated, but additional power consumption occurs that defeats the purpose of navigation-triggered pre-adjustment
Solution Approach 1:
The system preemptively prevents unnecessary power consumption by rejecting user operations for temperature adjustment when operating in the first mode. Since the navigation-triggered mode already optimizes battery temperature for charging conditions, additional user-initiated adjustments would consume extra energy without providing benefit. The processor is configured to reject such operations in advance, maintaining energy efficiency while still allowing user control when needed (in the second mode)
3Adaptability or versatility
If the system switches to the second mode upon receiving user operations, then user temperature preferences can be fulfilled, but the navigation-triggered temperature optimization is disrupted and additional power consumption occurs
Solution Approach 1:
The system maintains dynamic mode switching capability, allowing transition between the first mode (navigation-triggered optimization) and the second mode (user-operated adjustment). When a user operation is received while in the first mode, the processor switches to the second mode to fulfill the user's temperature preference request. This dynamic adaptation ensures the system can respond to user needs while minimizing unnecessary energy consumption by only switching modes when actually required

AI summary
A battery temperature adjustment system includes: a temperature adjustment device adjusts a temperature of a power storage device; and a processor. A setting mode of the temperature adjustment device includes: a first mode in which, in response to a travel route of includes a charging facility, the temperature is adjusted within a first temperature range suitable for charging at a time of arrival at the facility; and a second mode in which, in response to receiving a predetermined operation for adjusting the temperature within a second temperature range suitable for charging or traveling, the temperature is adjusted within the second temperature range. The processor controls the temperature adjustment device to adjust the temperature according to the setting mode; and when the setting mode is the first mode, rejects the predetermined operation and maintain the first mode in a case where the predetermined operation is received.
