External Start-Up Power Path for Lightweight Power Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power storage devices require a sub battery with large capacity to switch from a non-started-up to a started-up state, which reduces the convenience of power devices due to increased size and weight.
Innovation Solution
A start-up device with a switching controller and a power source part external to the power storage device, allowing for switching between started-up and non-started-up states, using a power source part electrically connectable to the switching controller via separate power transmission routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sub battery with large capacity is used to supply electric power for switching the power storage device to the started-up state, then the power storage device can be reliably started up, but the size and weight of the power device increase, reducing convenience
Solution Approach 1:
The invention divides the power supply function into two separate paths: a first power transmission route for supplying power to the operating part, and a second power transmission route for supplying power to the switching controller. This segmentation allows the sub battery to be smaller since it only needs to power the switching controller during start-up, not the entire system, thereby reducing weight while maintaining reliable start-up functionality.
Solution Approach 2:
The invention introduces a switching controller as an intermediary component that manages the transition between non-started-up and started-up states. The switching controller receives power from the sub battery through the second power transmission route and controls the switching of the power storage device, enabling reliable start-up without requiring a large capacity sub battery.
2Reliability
If a sub battery with large capacity is used to supply electric power for switching the power storage device to the started-up state, then the power storage device can be reliably started up, but the volume of the power device increases, reducing convenience

3Weight of moving object
If a separate second power transmission route is provided for the power source part to the switching controller, then the sub battery capacity can be reduced, but the device complexity increases
Solution Approach 1:
The switching controller serves multiple functions: it controls the switching between non-started-up and started-up states, manages the power transmission routes, and coordinates the operation of the power storage device. This multi-functionality justifies the additional complexity of the second power transmission route, as the switching controller integrates multiple control functions in one component.

AI summary
A start-up device is a start-up device of a power storage device having a power storage. The power storage device includes a switching controller configured to switch between a started-up state in which electric power of the power storage can be output to outside of the power storage device or in which electric power outside of the power storage device can be input to the power storage and a non-started-up state in which electric power of the power storage cannot be output to the outside of the power storage device and in which electric power outside of the power storage device cannot be input to the power storage. The start-up device includes a power source part provided outside of the power storage device and electrically connectable to the switching controller.
