Smart External Battery Module for UPS Runtime Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional uninterruptible power supplies (UPS) systems have limited backup time and require additional space and cost due to the use of external battery modules (EBMs) to extend runtime, which are often 'dumb' and lack intelligence.
Innovation Solution
The implementation of smart external battery modules (EBMs) with a super charger that uses a separate AC power source to charge batteries, allowing for extended backup time and reducing the number of EBMs needed, thereby saving space and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional external battery modules (EBMs) are used to extend backup time, then backup time is extended, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple EBMs into a single integrated EBM unit that contains multiple battery strings. This merging approach extends backup time while reducing system complexity by eliminating the need for multiple separate EBM devices and their associated monitoring circuits.
Solution Approach 2:
The patent creates a universal EBM design that can serve multiple functions: it can be coupled to different UPS models, provide extended backup power, and include intelligent monitoring capabilities. This multi-functional approach reduces the need for specialized devices for different applications.
2Duration of action of moving object
If multiple external battery modules are used to extend backup time, then backup time is extended, but space requirements increase
Solution Approach 1:
The patent merges multiple battery strings into a single EBM physical unit, consolidating what would have been multiple separate devices into one compact unit. This reduces the total space required while maintaining the extended backup time capability.
3Duration of action of moving object
If multiple external battery modules are used to extend backup time, then backup time is extended, but cost increases
Solution Approach 1:
The patent combines multiple battery strings and their monitoring functions into a single EBM unit, reducing the total number of devices needed. This consolidation lowers material costs, assembly costs, and reduces the need for multiple communication interfaces and mounting hardware.
4Duration of action of moving object
If smart external battery modules with monitoring circuits are used, then run-time is extended, but device complexity increases
Solution Approach 1:
The patent combines multiple battery string monitoring functions into a single integrated monitoring system within the EBM. This single monitoring circuit can track the status of all battery strings, reducing the overall complexity compared to having separate monitoring circuits for each individual string or module.
