Solution Overview
Problem
Existing power supply systems do not efficiently utilize electrical power source units, often relying on batteries only during commercial power source abnormalities or time-zone dependent charge/discharge strategies, without optimizing the use of both power source units for efficient power distribution.
Innovation Solution
An electrical power control system that includes a supply control circuit to prioritize battery power over power source unit power when the battery charge is sufficient, using a threshold-based control mechanism to manage power distribution between the electrical power source unit and the battery unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If battery power is used preferentially when charge is sufficient, then power loss from the power source unit is reduced, but the system complexity increases due to threshold-based control mechanisms
Solution Approach 1:
The system changes the operating parameter (power source selection) based on the battery charge level parameter. When the battery charge amount is above a predetermined threshold, the system switches to preferential battery power supply mode; when below the threshold, it switches to power source unit mode. This parameter-based switching resolves the contradiction by automatically optimizing power loss without requiring complex manual control mechanisms.
2Reliability
If the power source unit operates continuously, then stable power supply is maintained, but load variations cause increased power loss and reduced efficiency
Solution Approach 1:
The system dynamically adjusts the power supply configuration based on real-time battery charge levels. Instead of continuous operation from the power source unit, the system transitions between two operational states: battery-preferential mode (when charge is sufficient) and power source unit mode (when charge is low). This dynamic adaptation maintains reliability while minimizing power loss by avoiding continuous operation of the power source unit under varying load conditions.
3Loss of energy
If battery power is prioritized over power source unit power, then the duration and amount of power from the power source unit is reduced, but the battery charge level must be continuously monitored
Solution Approach 1:
The supply control circuit automatically monitors the battery charge amount and makes autonomous decisions about power source selection without requiring external intervention. The system self-manages the switching between battery and power source unit based on the threshold comparison, thereby reducing power loss while maintaining appropriate levels of automation through built-in monitoring capabilities.

AI summary
An electrical power control apparatus controls electrical power supply from an electrical power source unit and a battery unit to a target of supply. The electrical power control apparatus includes a supply control circuit. The supply control circuit supplies electrical power of the battery unit in preference to electrical power of the electric power source unit to the target of supply when an amount of charge of the battery unit is equal to or higher than a threshold.
