Detachable Battery Thermal Attachment for Swap Station Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery replacement systems make batteries heavier and more complex by incorporating heating medium flow paths for temperature control, which is not necessary for managing battery temperature during attachment to a vehicle.
Innovation Solution
A battery replacement station with a detachable temperature adjustment member that allows heat generation or absorption without a heating medium flow path, attached to the battery's outer surface before or during transport, to manage battery temperature within a desired range without increasing weight or complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating medium flow path is provided in the battery for temperature control, then the battery temperature can be managed, but the battery becomes heavier and the structure becomes more complicated
Solution Approach 1:
The patent extracts the temperature control function from the battery structure itself and relocates it to an external attachment. The heating medium flow path is removed from the battery, and instead a separate temperature adjustment member with its own heating/cooling functionality is attached to the battery outer surface, thereby achieving temperature control without adding internal complexity or weight to the battery
2Temperature
If a heating medium flow path is provided in the battery for temperature control, then the battery temperature can be managed, but the battery structure becomes more complicated
Solution Approach 1:
The temperature control system is extracted from the battery structure and implemented as an external attachment. The heating medium flow path is completely removed from the battery design, and a separate temperature adjustment member containing the necessary heating/cooling mechanisms is attached to the battery outer surface, significantly simplifying the battery structure while maintaining temperature control capability
Solution Approach 2:
The temperature control function is segmented from the battery structure and implemented as a separate, detachable component. This allows the battery to remain structurally simple while the temperature adjustment member handles all temperature control functions through its own integrated heating/cooling mechanisms

AI summary
Provided is a battery replacement station in which a used battery that has been discharged is removed from a vehicle and is replaced with a charged battery. The battery replacement station includes: a battery storage area in which the charged battery is stored; and a temperature adjustment member storage area that stores a temperature adjustment member. The temperature adjustment member is detachably attachable to an outer surface of the charged battery and allows at least one of heat generation and/or heat absorption without including a heating medium flow path through which a heating medium circulates.
