Wireless Battery Monitoring via BLE Unit Identification Broadcast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage battery monitoring systems require extensive wiring for data acquisition, leading to increased network laying and communication costs, particularly in large-scale energy storage systems, making remote monitoring inefficient and costly.
Innovation Solution
A storage battery monitoring apparatus utilizing wireless communication, specifically Bluetooth Low Energy (BLE), with monitoring units attached to batteries and a management unit that establishes one-to-one communication through identification information broadcasted in messages, allowing for remote monitoring while minimizing wiring and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wireless communication is used for monitoring storage batteries, then wiring cost is reduced, but communication reliability may be compromised
Solution Approach 1:
The management unit performs preliminary actions by broadcasting identification information to multiple monitoring units before establishing communication. Each monitoring unit stores this identification information and uses it to respond appropriately, ensuring reliable one-to-one communication is established beforehand before actual data acquisition begins.
Solution Approach 2:
The system implements feedback mechanisms where monitoring units transmit their identification information back to the management unit, and the management unit confirms receipt and establishes communication based on this feedback. This ensures reliable communication establishment while maintaining wireless communication benefits.
2Ease of operation
If identification information is broadcasted to all monitoring units, then communication establishment is simplified, but power consumption increases
Solution Approach 1:
The management unit broadcasts identification information to all monitoring units (excessive action), but only the specific monitoring unit that needs communication actually processes and responds to this information. This approach simplifies the communication establishment process while the selective response mechanism helps control overall power consumption in the system.

AI summary
A storage battery monitoring apparatus includes: monitoring units attached to storage batteries connected in series and/or in parallel; and a management unit capable of wireless communication connection with the monitoring units. By using identification information of a specific monitoring unit included in a message broadcasted from the management unit to the monitoring units, communication between the management unit and the specific monitoring unit is established.
