Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery replacement mechanisms for electric vehicles are hindered by unstable communication between station management devices and system management devices, leading to potential delays or failures in battery replacement services. Additionally, current battery rental methods can result in uneven wear and maintenance challenges for shared batteries.
Innovation Solution
A power storage device management system that includes a server device configured to store identification information of shared power storage devices and a storage device capable of independently determining the provision of stored power storage devices based on stored identification information, even in situations where communication with the server device is not available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery replacement relies on real-time communication between station management device and system management device, then centralized control and coordination are improved, but service reliability deteriorates when communication is unstable or unavailable
Solution Approach 1:
The system divides the centralized management function into two parts: the server device maintains the master battery management database, while the storage device obtains and stores a copy of the battery list locally. This segmentation allows the storage device to operate independently when communication is unavailable, improving service reliability without requiring complex communication protocols.
Solution Approach 2:
The storage device preliminarily obtains and stores the battery list information from the server device before communication issues arise. By having the battery list available in advance, the storage device can perform battery replacement operations without real-time communication, eliminating the dependency on stable communication during critical operations.
2Productivity
If automated battery replacement is implemented without staff intervention, then service efficiency and productivity are improved, but system complexity and communication requirements increase
Solution Approach 1:
The storage device is designed to autonomously determine whether to accept a battery based on locally stored battery list information, without requiring real-time communication with the server or staff intervention. The device compares the battery's identification information with the stored list and automatically accepts or rejects the battery,实现ing self-service functionality that improves productivity while keeping the system relatively simple.
Solution Approach 2:
The battery list is obtained and stored in advance in the storage device, enabling automated decision-making during battery replacement operations. This preliminary action eliminates the need for complex real-time communication protocols and staff intervention, as the device has all necessary information available locally to make automated acceptance decisions.
3Measurement precision
If battery list is obtained from server device at every battery replacement, then data accuracy and consistency are improved, but service speed and responsiveness deteriorate
Solution Approach 1:
The storage device preliminarily obtains the battery list from the server device and stores it locally before battery replacement operations begin. This allows the device to quickly compare incoming battery identification information with the stored list without requiring time-consuming real-time communication during the replacement process, thus maintaining data accuracy while reducing service time.
Solution Approach 2:
The system segments the data acquisition process from the decision-making process. The battery list is obtained separately in advance from the server, while the battery acceptance decision is made locally using the stored list. This segmentation eliminates the need for real-time communication during battery replacement, reducing service time while maintaining data accuracy through the pre-obtained list.
4Ease of operation
If uniform battery rental method is used for all shared batteries, then operational simplicity is improved, but maintenance costs increase due to uneven wear
Solution Approach 1:
The storage device maintains local information about each battery's characteristics and usage status in the stored battery list. This allows the system to apply different rental conditions or maintenance schedules to different batteries based on their specific qualities and wear patterns, rather than applying a uniform approach to all batteries, thereby reducing maintenance costs while keeping operations simple.

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.
