Conventional UPS systems lack adaptable and modular battery management and monitoring solutions for lead acid batteries, particularly in terms of interface options, safety measures, and compliance with industry standards, and are limited in their ability to handle power failures and extended runtime requirements, especially with the transition to lithium chemistry batteries.
Innovation Solution
A battery management and monitoring system that includes a controller and memory to monitor parameters of battery modules, generate control signals to isolate the battery module if thresholds are exceeded, and is integrated with a control circuit and voltage converter, enabling modular and self-contained monitoring and management of lithium battery modules within a UPS cabinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lead acid battery management systems are used, then the system can provide basic monitoring functionality, but the system lacks adaptability to different battery types and interface options
Solution Approach 1:
The battery management system is designed with a universal architecture that can accommodate multiple battery chemistries (lead acid, lithium-ion, lithium polymer) through configurable parameters and algorithms. The system provides multiple interface options (display, communication protocols) and can be adapted to different UPS system configurations without requiring complete system redesign, thus achieving multi-functionality and broad adaptability.
2Reliability
If conventional battery management systems are used, then the system can operate with basic functionality, but the system cannot function independently during power failures
Solution Approach 1:
The battery management system incorporates self-service capabilities by including its own power management circuitry that can operate independently from the main UPS system during power failures. The system monitors battery voltage, current, and temperature using dedicated sensors and continues to provide monitoring and control functions even when the UPS is not powered, ensuring continuous reliability without requiring external power sources.
3Duration of action of moving object
If lead acid batteries are used in UPS systems, then the system can provide emergency power, but the system has limited runtime and poses safety hazards
Solution Approach 1:
The system transitions from lead acid battery chemistry to lithium-based battery chemistry, fundamentally changing the chemical parameters of the energy storage medium. This parameter change enables extended runtime capabilities while eliminating the safety hazards associated with lead and sulfuric acid, including toxic emissions, corrosion, and spill risks. The lithium chemistry provides higher energy density and inherent safety improvements.
4Adaptability or versatility
If conventional battery management systems are used, then the system can provide basic monitoring, but the system lacks modular and self-contained enclosure options
Solution Approach 1:
The battery management system is designed as a modular, self-contained enclosure unit that can be independently installed and configured. The system segments the monitoring and control functions into a discrete module that interfaces with the UPS system through standardized connections. This modular design allows the enclosure to be adapted to different installation environments and battery configurations without requiring complex custom enclosures for each application.
Data Source
AI summary
A battery management and monitoring system for monitoring a lithium battery module is provided. The battery management and monitoring system may include a memory configured to retrievably store one or more algorithms, and a controller in communication with the memory. Based on the one or more algorithms, the controller may be configured to at least monitor a data signal corresponding to one or more parameters indicative of an operating condition of the lithium battery module, and generate a control signal based on the data signal configured to selectively engage one or more contactors in communication with the lithium battery module to at least temporarily isolate the lithium battery module if one or more of the parameters exceed predefined thresholds.
