Shared Battery Storage Control Under Unstable Server Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery sharing service systems face challenges with communication stability and speed issues between station management devices and system management devices, leading to potential malfunctions and increased costs due to the need for frequent software customization and maintenance, especially when renting out batteries with varying charging states.
Innovation Solution
A power storage device management system that includes a storage device and a server device connected via a network, where the server stores identification information of shared batteries and the storage device determines battery reception based on this information, allowing independent operation even when communication with the server is unstable, and manages battery provision according to predetermined rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system continuously communicates with the server to manage battery provision, then the centralization of management is improved, but communication stability issues cause malfunctions and service interruptions
Solution Approach 1:
The storage device pre-fetches and stores the battery provision management table from the server before communication issues occur. This preliminary action allows the device to operate independently using stored data when communication becomes unstable, preventing service interruptions while maintaining centralized management capabilities when communication is available.
2Loss of information
If the system frequently checks communication status and updates battery information, then the data freshness is improved, but the complexity of communication protocols and system operations increases
Solution Approach 1:
The system implements periodic communication cycles where the storage device automatically requests and updates the battery provision management table at predetermined intervals. This periodic approach ensures data freshness without requiring complex continuous communication protocols, simplifying the system while maintaining up-to-date information.
3Productivity
If the system rents out batteries with varying charging states to maximize utilization, then the productivity is improved, but the difficulty of managing battery states and determining provision increases
Solution Approach 1:
The storage device autonomously determines battery provision and manages charging states without requiring complex external coordination. By using the stored battery provision management table, the device can independently identify which batteries to rent out and which to charge, maximizing utilization while simplifying management through self-service operations based on pre-fetched centralized data.

AI summary
A power storage device management system includes a storage device configured to store power storage devices that are removably mounted on an electric power device using electric power and a server device communicatively connected to the storage device. The server device includes a first storage unit storing identification information of a power storage device shared by a plurality of users among the power storage devices as storage identification information. The storage device includes a second storage unit storing the storage identification information received from the server device and a determiner configured to determine whether or not reception of the power storage device is possible on the basis of the storage identification information stored in the second storage unit when the power storage device has been received from a user.
