Backup Power Supply Control Circuit for Energy Loss Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Backup power supplies, such as lithium-ion and energy batteries, continue to dissipate energy when not actively powering external equipment, leading to inefficiency and potential failure during emergencies due to continuous charging and discharging cycles.
Innovation Solution
A circuit comprising a switch unit, control unit, processing unit, and additional components like diodes, energy storage units, and DC-DC modules is designed to manage the backup power supply, allowing for controlled on/off states and energy management to prevent wastage and protect against reverse currents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the backup power supply continuously supplies power to internal functional circuits, then the circuits remain operational, but energy is wasted during non-working modes
Solution Approach 1:
The control unit is configured to receive a shutdown signal before the power supply stops providing power to external equipment, and accordingly shuts down the internal functional circuits. This preliminary action ensures that circuits are turned off in advance before power is completely cut off, preventing energy waste during non-working modes while maintaining operational readiness when needed.
2Loss of energy
If the backup power supply is shut down to save energy, then energy loss is reduced, but the system may not be ready for emergency operation
Solution Approach 1:
The control unit receives real-time status signals from the power supply system and adjusts the operation of internal functional circuits accordingly. When the power supply stops providing power to external equipment, the control unit receives a shutdown signal and consequently shuts down the internal circuits, creating a feedback mechanism that optimizes energy efficiency while maintaining emergency readiness through responsive control.
3Adaptability or versatility
If multiple functional circuits are used for charging and discharging, then the battery management is comprehensive, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it monitors the power supply status, receives shutdown signals, controls the internal functional circuits, and manages the overall power distribution. By making the control unit multi-functional, the patent reduces the need for separate dedicated circuits for each function, thereby managing battery operations comprehensively while minimizing device complexity.
