Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery power supply devices face limitations in power supply due to output limitations of battery inverters, leading to potential instantaneous power failures and complex circuitry with the use of power static switches, which complicates maintenance and increases costs.
Innovation Solution
A battery power supply device that directly connects to an external power source without a power static switch, utilizing an input unit, battery power unit, and current detection unit to manage power distribution, allowing for efficient use of both external and battery power, and adjusting output based on load current detection to prevent power failures and optimize inverter capacity.

Engineering Contradiction Analysis
1Reliability
If a power static switch is used to select between battery power and external power, then power supply capability is improved, but circuit complexity increases and maintenance difficulty increases
Solution Approach 1:
The patent removes the power static switch from the circuit entirely. Instead of using a static switch to select between battery power and external power, the system directly connects both power sources to the load through separate paths, eliminating the need for switching components and their associated complexity.
Solution Approach 2:
The patent divides the power supply into separate independent paths: one path for battery power and another path for external power. Each path operates independently without requiring switching between them, allowing both power sources to be utilized simultaneously or independently based on load requirements.
2Power
If external power and battery power are used simultaneously, then power capability is improved, but circuit complexity increases
Solution Approach 1:
The patent uses segmentation by creating separate independent paths for battery power and external power that converge at a common load node. This simple parallel architecture allows simultaneous power usage without requiring complex control circuits, switches, or synchronization mechanisms.

AI summary
A battery power supply device is provided. The battery power supply device includes: an input unit that receives external power; a battery power unit that is connected to the input unit to charge a battery with the external power; a current detection unit that detects a current that is supplied to a load and that provides the current to the battery power unit; and an output unit that provides the external power and battery power from one node to the load and that receives a load current from the battery power unit to adjust output of the battery power.
