Replaceable Battery Storage with Constant-Temperature Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, fixed batteries often operate below their nominal performance due to safety restrictions and charging is slow, prompting the need for a replaceable battery solution that ensures batteries are in an appropriate state during replacement.
Innovation Solution
A storage method involving a controlled environment with a constant temperature and charging system for detachable, replaceable batteries, allowing for uniform storage and management of batteries based on their deterioration state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery is fixed to a vehicle body, then safety restrictions can be enforced, but the nominal performance of the battery cannot be fully used and charging takes a long time
Solution Approach 1:
The battery system is segmented into a fixed vehicle body structure and a replaceable battery unit. This allows the battery to be quickly exchanged rather than charged in place, resolving the contradiction between safety (maintained through controlled storage) and productivity (improved through rapid replacement).
Solution Approach 2:
Batteries are pre-charged and stored in advance in a storage facility before being installed in the vehicle. This preliminary charging action eliminates the need for slow on-vehicle charging, thereby improving productivity while safety is maintained through pre-established storage conditions.
2Productivity
If a replaceable battery is employed, then charging time is reduced, but the battery must be in an appropriate state at the time of replacement which requires storage management
Solution Approach 1:
A dedicated storage facility acts as an intermediary between the charging infrastructure and the vehicle. This intermediary maintains batteries in appropriate states (charged, temperature-controlled) so that when replacement is needed, the battery is already prepared, thus simplifying the replacement process while managing the complexity of battery state maintenance.
Solution Approach 2:
The storage facility controls key parameters such as temperature and charge state of batteries before they are installed in vehicles. By maintaining batteries at optimal parameters in advance, the system enables rapid replacement without compromising battery performance or safety, balancing productivity improvement with manageable storage complexity.
3Productivity
If multiple batteries are stored in a storage facility, then vehicle replacement needs are met, but transportation and storage infrastructure is required
Solution Approach 1:
The storage facility is designed to perform multiple functions: charging batteries, maintaining them at appropriate temperatures, and storing them ready for installation. This multi-functionality consolidates what would otherwise require separate infrastructure systems, thereby improving battery availability while limiting the growth of infrastructure complexity.
