Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Equipment products reliant on portable and rechargeable power storage devices often fail to maintain internal electronic components operational during power-off or when backup batteries are absent or damaged, due to structural and cost-related issues.
Innovation Solution
A power storage device with a management unit that detects connection events, outputs electric power under a discharging limit, and authenticates with a load device before lifting the limit, ensuring safe and controlled power distribution, preventing damage from excessive power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a backup battery is disposed to provide fundamental electric power for internal electronic components during power-off, then the operation reliability of internal electronic components is improved, but the fabrication cost and structural complexity increase
Solution Approach 1:
The patent combines the backup battery function with the main power storage device by integrating a control unit that manages power output based on connection status. The control unit enables the power storage device to automatically provide standby power to internal electronic components during power-off without requiring a separate backup battery, thus merging two functions into one system.
Solution Approach 2:
The power storage device is designed to perform multiple functions: it serves as both the main power source during operation and the backup power source during power-off. The control unit enables the device to adapt its power output based on whether the equipment is powered on or off, making the same device universally applicable for both primary and backup power needs.

The control unit enables the power storage device to automatically provide standby power to internal electronic components during power-off without requiring a separate backup battery, thus merging two functions into one system.
3Speed
If the power storage device outputs electric power without authentication, then the power output speed is improved, but the safety and reliability of power distribution deteriorates
Solution Approach 1:
The control unit performs authentication as a preliminary action before enabling full power output. When the power storage device detects connection to a load device, it first conducts mutual authentication through the electrical connection unit. Only after successful authentication does the control unit lift the discharging limit and enable normal power output, ensuring safety before speed.
Solution Approach 2:
The discharging limit is dynamically adjusted based on authentication status. During authentication, the discharging limit is maintained at a restricted level. Upon successful authentication, the control unit dynamically lifts the discharging limit to enable full power output. This dynamic adjustment ensures both safety during the authentication process and efficient power delivery afterward.

AI summary
Disclosed is a power storage device and method for discharging the same, which configures the power storage device to perform an electric power output under a discharging limit upon coupling with a load device and before any authentication is conducted. The discharging limit for the electric power output will be lifted only when an authentication result between the power storage device and the load device indicates a successful authentication.
