Battery Charger Management System with Backup Power for Remote Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management systems for industrial vehicles and battery chargers cannot collect or manage information on the state of batteries or battery chargers during charging, as the main control unit and data communication module lack power when a backup battery is not present, preventing communication with external management systems.
Innovation Solution
A management system and battery charger configuration that includes a communication unit to transmit information on the battery's state and usage state to a management system via a communication network, allowing remote management and data storage for statistical processing and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a backup battery is not provided in the vehicle, then the vehicle structure is simplified and cost is reduced, but the main control unit and data communication module lack power during charging, preventing communication with external management systems
Solution Approach 1:
The patent introduces a backup battery as an intermediary power source specifically for the data communication module during charging operations. This backup battery acts as a mediator that bridges the power supply gap, enabling the communication module to maintain operation and transmit battery state information to external management systems even when the main power source is disconnected for charging safety.
2Reliability
If the main control unit and data communication module are powered down during charging for safety, then charging safety is improved, but information on battery state and charger usage state cannot be transmitted to external management systems
Solution Approach 1:
The patent segments the power supply system into multiple independent components: the main power source for vehicle operation, the backup battery specifically for communication module power during charging, and the charger power source. This segmentation allows the communication module to remain powered and operational during charging without compromising charging safety, as the backup battery is electrically isolated from the main charging circuitry.
3Device complexity
If existing management systems are used without a backup battery, then the system is simpler and cheaper, but remote management and fleet management cannot be performed during charging operations
Solution Approach 1:
The patent implements preliminary action by pre-configuring a backup battery specifically for communication module operation during charging. This preliminary power supply arrangement ensures that before charging begins and the main power is disconnected, the communication module already has a dedicated power source ready, enabling continuous information transmission to external management systems throughout the charging process.
Data Source
AI summary
A management system and a management method of a battery and a battery charger, and a battery charger are provided that can obtain information on the state of a battery and information on the usage state of a battery charger even during charging so as to monitor/control the battery and the battery charger even during the charging.
