Battery Assembly Selection Based on Deterioration Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management systems fail to consider the varying usage patterns of vehicles when selecting cells and spacers for battery assemblies, leading to inadequate maintenance and reduced battery lifespan due to neglect of material deterioration alongside high-rate deterioration.
Innovation Solution
A battery information processing apparatus and method that obtain a vehicle's use history to generate assembly information for selecting cells and spacers, prioritizing either high resistance against material deterioration or high-rate deterioration based on a calculated ratio, ensuring appropriate component selection for each user's usage conditions.

If maintenance is performed based on general deterioration criteria, then battery assembly maintenance can be scheduled, but usage-specific deterioration patterns are not considered
Solution Approach 1:
The invention introduces feedback by calculating actual deterioration amounts based on usage history and comparing them to determine the dominant deterioration type. This feedback mechanism allows the maintenance system to adapt to actual usage patterns rather than following a fixed schedule, thereby improving both maintenance timing accuracy and usage-specific adaptability
Solution Approach 2:
The invention performs preliminary calculation of high-rate deterioration amounts and material deterioration amounts before determining maintenance timing. By预先 calculating these values based on usage history, the system can proactively identify the dominant deterioration type and select appropriate cells and spacers before actual failure occurs, improving both maintenance scheduling and usage adaptability

AI summary
A management server obtains information on a use history of a battery assembly used in a vehicle. The management server calculates an amount of material deterioration Dm and an amount of high-rate deterioration Dh by using the information on the use history of the battery assembly. When a ratio Dm/Dh is higher than a threshold value Th, the management server generates first assembly information indicating selection of a cell highly resistant against material deterioration and a spacer highly resistant against material deterioration (a cell A and a spacer A). When the ratio Dm/Dh is lower than the threshold value Th, the management server generates second assembly information indicating selection of a cell highly resistant against high-rate deterioration and a spacer highly resistant against high-rate deterioration (a cell B and a spacer B).
