Automatic Battery Node Addressing via Power Signal Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems face complexity in wiring and address management, making it difficult to replace batteries and assign unique addresses, especially when the existing address systems are not designed for dynamic changes in battery configuration.
Innovation Solution
A method and system for automatically assigning addresses to battery nodes using an addressing power supply and bypass switches, where each node senses the power signal, assigns a unique address, and communicates with the master controller to confirm and propagate the address assignment sequentially through the series-connected nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual address assignment and rewiring is used for battery replacement, then unique address identification is achieved, but wiring complexity and difficulty of replacement increase
Solution Approach 1:
The battery node automatically assigns its own address by detecting the addressing power signal and storing the address value in its memory without external intervention. The system self-configures when a battery is replaced, eliminating the need for manual address assignment and reducing wiring complexity.
Solution Approach 2:
The address assignment is performed automatically during the battery replacement process itself, before the battery begins normal operation. The addressing power supply pre-configures the new battery's address as it is integrated into the series circuit, so the battery is ready for immediate use without additional manual configuration steps.
2Reliability
If manual address assignment is performed, then unique addresses are assigned to batteries, but time and labor for replacement increase
Solution Approach 1:
The battery node automatically detects the addressing power signal and assigns its own address without requiring technician intervention for address configuration. This self-service mechanism eliminates the time-consuming manual address assignment process during battery replacement.
Solution Approach 2:
The manual mechanical process of assigning addresses (writing down, entering, or configuring addresses) is replaced by an automatic electrical detection and storage system. The battery node's sensor detects the addressing power signal and the processor automatically stores the address value in memory, replacing manual operations with automated electronic processes.
3Reliability
If traditional wiring and address management is used, then battery metrics can be monitored, but ease of operation and maintenance decrease
Solution Approach 1:
The battery node automatically configures itself by detecting the addressing power signal and storing its address, making battery replacement as simple as physically swapping the battery without any additional configuration steps for the technician.
Solution Approach 2:
The addressing power signal serves multiple functions: it provides power during the addressing phase and simultaneously carries the address assignment information. This multi-functionality simplifies the system by using a single signal for both power and configuration, improving ease of operation.
