Removable Battery Pack Motion Logging for Pre-Mount Damage Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs for movable machines like electric motorcycles cannot diagnose damage to the battery unit before it is mounted, as they lack the capability to detect external physical loads during storage and transfer.
Innovation Solution
Incorporating a detector, memory device, and processing unit within the battery pack to record and analyze motion information, including temperature data, allowing for pre-mounting diagnosis of the battery unit's state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery unit is designed to be removably mounted on a movable machine, then it can be stored and transferred separately, but it cannot be diagnosed for damage before mounting
Solution Approach 1:
The patent applies preliminary action by equipping the battery unit with a detector and processing device that continuously monitor motion information and temperature during storage and transfer phases, before the battery is mounted on the movable machine. This enables damage diagnosis to occur in advance, resolving the contradiction between removable design and pre-mounting diagnostic capability.
2Reliability
If a detector is added to the battery pack to detect motion, then pre-mounting diagnosis is enabled, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the detector and processing device in the battery pack to serve multiple functions: detecting motion during storage/transfer for damage diagnosis, and also detecting motion during vehicle operation for posture estimation. This multi-functionality reduces the need for separate diagnostic devices, thereby limiting the increase in device complexity.
3Measurement precision
If motion detection is continuously monitored, then accurate damage diagnosis is achieved, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by having the processing device analyze motion information at specific intervals or under specific conditions (e.g., when abnormal motion is detected), rather than continuously processing all motion data. This periodic analysis maintains measurement precision for damage diagnosis while reducing overall energy consumption during storage and transfer phases.
