Solution Overview
Problem
Current backup energy storage systems with multiple devices face challenges such as insufficient energy use, power failures, slow switching speeds, and increased power consumption when used in series, along with inconvenient manual operation and lack of intelligence in managing multiple devices.
Innovation Solution
A parallel switching system utilizing multiple backup energy storage devices connected in parallel, with each device equipped with an AC charging interface, switching module, AC output interface, AC output module, and communication module, allowing for intelligent scheduling via Wi-Fi to optimize power supply duration and stability by switching between power supply and wire modes based on energy thresholds and device availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If multiple backup energy storage devices are used in series, then the power supply duration is extended, but the switching speed becomes slow and power failures occur during switching
Solution Approach 1:
The system segments the power supply function across multiple independent backup energy storage devices, each capable of operating autonomously. This segmentation allows parallel operation where multiple devices can supply power simultaneously or switch instantly between them, eliminating the slow sequential switching problem while maintaining extended power supply duration.
Solution Approach 2:
Multiple backup energy storage devices are merged into a parallel configuration where their output terminals are connected together. This merging enables them to function as a unified power supply system with combined capacity, allowing instant switching between devices without the sequential delays inherent in series connections.
2Duration of action of moving object
If multiple backup energy storage devices are used in series, then the power supply duration is extended, but additional power consumption occurs due to multi-device operation
Solution Approach 1:
The system dynamically controls the operation state of each backup energy storage device based on real-time conditions. The intelligent control unit monitors battery levels and activates only the necessary number of devices, allowing them to operate in parallel when needed and remain dormant otherwise, thus extending power supply duration while minimizing energy loss from unnecessary device operation.
3Ease of manufacture
If manual setting is used for multi-device operation, then the system is easier to manufacture, but the operation becomes inconvenient and lacks intelligence
Solution Approach 1:
The system implements self-service through an intelligent control unit that automatically monitors the states of all backup energy storage devices and makes operational decisions without user intervention. The control unit autonomously determines which devices to activate, manages power distribution, and handles switching operations, making the system both easy to manufacture (using standard control components) and extremely convenient to operate (fully automated).

AI summary
The disclosure discloses a scheduling method for collaborative work of multi-device in a parallel switching system, the method comprises: providing a load and N backup energy storage devices, n is a positive integer greater than or equal to 2; and connecting the AC output interfaces of the N backup energy storage devices to the load or assembling the AC charging interfaces of the N backup energy storage devices to form a parallel switching system and obtaining numbers 1 to N according to the sequence of the communication modules accessing Wi-Fi hotspots. When the backup energy storage device with any number is switched to the load in the power supply mode, the other backup energy storage devices are switched to the wire mode to transfer current. When the electric quantity of the backup energy storage device reaches the electric quantity threshold, the communication module of the backup energy storage device will notify another numbered backup energy storage device to start the AC output module, and then switch to provide power supply to the load in the power supply mode.
