Emergency Battery Pack Integration in Low Voltage Power Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency battery packs for low voltage systems are not efficiently designed to provide continuous power during interruptions in the primary power source, particularly in Class 2 circuits, which require safe and reliable operation without the need for licensed electrical professionals for installation and maintenance.
Innovation Solution
A distributed low voltage power system incorporating an emergency battery pack (EBP) that uses a low voltage signal to charge battery cells and release an emergency low voltage signal to electrical devices when the primary power source is interrupted, with a switch mechanism to control power distribution and comply with safety standards like Class 2 device criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional emergency battery packs are used in low voltage systems, then power backup is provided during interruptions, but the system complexity increases and installation/maintenance requires licensed electrical professionals
Solution Approach 1:
The patent combines the emergency battery pack functionality directly into the Power Distribution Module (PDM), merging the backup power source with the existing power distribution infrastructure. This integration eliminates the need for separate emergency battery pack installations and reduces overall system complexity while maintaining power continuity during interruptions.
Solution Approach 2:
The PDM is designed to perform multiple functions: normal power distribution, emergency power backup, and automatic switching between power sources. By making the PDM universal and multi-functional, the system eliminates the need for dedicated emergency power equipment, thereby reducing system complexity and allowing non-licensed personnel to install and maintain the system.
2Reliability
If traditional emergency battery packs are installed, then power backup is ensured, but installation and maintenance costs increase due to licensing requirements
Solution Approach 1:
By merging the emergency battery functionality into the standard PDM, the system eliminates the need for separate emergency power installations. This integration allows non-licensed personnel to install and maintain the system, significantly reducing installation and maintenance costs while ensuring power backup reliability.
3Power
If high voltage systems are used for emergency power, then sufficient power is provided, but safety risks increase and regulatory compliance becomes more difficult
Solution Approach 1:
The patent changes the voltage parameter from high voltage to low voltage (Class 2) operation for the emergency battery pack. This parameter change provides sufficient power for low voltage devices while dramatically reducing safety risks and simplifying regulatory compliance, allowing installation by non-licensed personnel.
