Battery Pack Encoder for Identification Code Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric power systems with battery packs require inconvenient processes for changing identification codes, such as re-burning or resetting, when replacing battery packs, which complicates the management and integration of new battery packs.
Innovation Solution
Incorporating an encoder with a manually adjustable encoding configuration in each battery pack, allowing users to set a specific identification code, enabling universal battery pack functionality and simplifying the process of replacing battery packs by matching the encoding configuration of new packs to the removed ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the identification code is burned into a non-volatile memory of the monitoring unit, then the identification code is fixed and stable, but changing the identification code requires re-burning via a recording device which is inconvenient
Solution Approach 1:
The patent transforms the static identification code stored in non-volatile memory into a dynamic code generated by an encoder component. The encoder can be manually adjusted to different positions, each position corresponding to a different identification code. This allows the identification code to change dynamically based on the encoder's position, eliminating the need for re-burning while maintaining code stability during operation.
Solution Approach 2:
The patent replaces the electronic/memory-based identification code storage system with a mechanical encoder system. Instead of storing codes electronically in non-volatile memory, the system uses a mechanical encoder with multiple positions that generate different codes based on physical position. This mechanical approach allows easy code changes through manual adjustment without requiring recording devices.
2Productivity
If a new battery pack is replaced into the electric power system, then the system can use the new battery pack, but the identification code must be set or re-burned which complicates the replacement process
Solution Approach 1:
The patent enables the battery pack to self-identify through the encoder configuration. When a new battery pack is installed, the user simply adjusts the encoder to the desired position, and the system automatically generates the corresponding identification code. This eliminates the need for external recording devices or complex programming processes, allowing the battery pack to effectively configure itself with the appropriate identification code.
Solution Approach 2:
The patent makes the battery pack universal by allowing the same physical battery pack to be configured with different identification codes through encoder adjustment. A single battery pack design can serve multiple roles and be assigned to different positions or functions in the electric power system simply by changing the encoder position, rather than requiring different hardware versions for different applications.
