Battery Swap Performance Ranking and Comparison System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for swapping secondary batteries in vehicles only provide information on the location of swap stations and the number of charged batteries, lacking valuable insights for users to make informed decisions based on battery performance rankings.
Innovation Solution
An information output method that compares the performance rank of an onboard battery unit with installable units, outputting information on the comparison results to assist users in making informed swapping decisions, including assessments of charge count, fast charge count, full charge ratio, temperature exposure, and age, to differentiate battery performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only basic swap station location and battery count information is provided, then the system is simple and easy to operate, but users cannot make informed decisions about battery performance and swapping value
Solution Approach 1:
The patent segments battery performance information into distinct ranking criteria including charge count, fast charge count, full charge ratio, temperature exposure history, and age. Each criterion is evaluated separately and aggregated into an overall performance rank, allowing users to understand specific performance aspects while maintaining manageable information structure
Solution Approach 2:
The system performs preliminary assessment of battery performance ranks before the swap transaction occurs. By pre-evaluating both the battery to be swapped out and available swap-in batteries, the system provides users with informed decision-making capability in advance, enabling them to understand the value implications of swapping before committing to the transaction
2Ease of operation
If detailed performance comparison information is provided to users, then users can make informed swapping decisions, but the information processing and output system becomes more complex
Solution Approach 1:
The patent employs visual differentiation techniques where batteries of different performance ranks are displayed with distinct visual indicators. High-ranking batteries are highlighted differently from low-ranking ones, enabling users to quickly grasp performance differences without analyzing complex numerical data, thus maintaining ease of operation despite sophisticated underlying processing
Solution Approach 2:
The system transforms multiple complex performance parameters (charge count, fast charge count, temperature history, age) into a simplified rank parameter that represents overall battery performance. This parameter transformation allows the complex information processing system to present results in an easily interpretable format that enhances user decision-making capability

AI summary
Provided is an information output method that outputs information when swapping a secondary battery for powering a vehicle. The information output method includes comparing a rank related to the performance of a first battery unit (battery unit A) on board a vehicle to a rank related to the performance of a second battery unit (battery unit B) that is installable in the vehicle in place of the first battery unit, and outputting output information according to a result of the comparison in the comparing step.
