Modular Battery Pack With Per-Module Charge Cycle Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems lack the ability to efficiently manage and maintain charging cycles of individual battery modules, leading to inefficiencies and reduced lifespan due to lack of independent replacement and control mechanisms.
Innovation Solution
A battery pack design that includes individually replaceable battery modules with integrated recording elements to track charging cycles, along with a battery control module and management unit to manage charging and discharging, allowing for independent replacement and control of battery modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery modules are integrated into a single battery pack unit, then the battery pack can function as a complete energy source, but the battery modules cannot be individually replaced or maintained
Solution Approach 1:
The battery pack is divided into independent, modular battery modules that can be individually replaced. Each module contains its own recording element and can be detached from the frame independently, allowing selective maintenance and replacement without affecting other modules or the control module.
Solution Approach 2:
The battery control module is designed to work with multiple battery modules through standardized interfaces. The control module remains outside the battery modules and can manage different module configurations, providing universal control functionality across various module arrangements.
2Ease of operation
If battery control module is integrated with battery modules, then control is centralized, but battery modules cannot be replaced independently of the control module
Solution Approach 1:
The recording element is extracted from the battery control module and placed within each individual battery module. This allows charging cycle information to be stored locally in each module, preventing data loss when modules are replaced independently of the control module.
Solution Approach 2:
Charging cycle information is recorded and stored in the recording element before battery module replacement occurs. This preliminary data storage ensures that historical charging information is preserved and can be retrieved after module replacement, maintaining data integrity throughout the system lifecycle.
3Reliability
If recording element is placed in battery control module, then centralized control is achieved, but charging cycle information cannot be maintained after module replacement
Solution Approach 1:
The recording function is segmented from the central control module and distributed to individual battery modules. Each module contains its own recording element that independently stores charging cycle information, enabling modules to be replaced without affecting data retention or system complexity.
Data Source
AI summary
A battery pack includes battery modules configured to be individually replaced, a frame configured to accommodate the battery modules, and a battery control module outside the battery modules and configured to control charging and discharging of the battery modules. Each of the battery modules includes a recording element configured to record a charging cycle of the battery module.
