Server Device Charging Control for Power Storage Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The performance of storage batteries in power storage devices deteriorates over time, leading to abnormalities that can result in inefficient charging and increased frequency, causing inconvenience to users, especially in rental systems where users are billed based on charging cycles.
Innovation Solution
A method that involves receiving identification information and state values of power storage devices, comparing them to past data, and determining the possibility of charging before initiating the charging process to prevent inappropriate charging and manage the device based on its state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If charging is performed frequently to maintain power storage device availability, then the power storage device can be ready for use more often, but the storage battery deteriorates faster due to repeated charging cycles
Solution Approach 1:
The server device performs preliminary assessment of battery state before allowing charging to occur. By evaluating battery state information in advance and determining charging suitability beforehand, the system prevents charging when the battery is in an unsuitable state, thereby reducing deterioration while maintaining productivity.
2Duration of action of moving object
If the storage battery is used continuously without monitoring, then operational availability is maintained, but abnormalities go undetected causing user inconvenience
Solution Approach 1:
The system implements continuous monitoring with feedback mechanisms where the server device receives battery state information from the power storage device, evaluates it against predetermined criteria, and provides control instructions back to the charging device. This closed-loop feedback enables continuous operation while ensuring abnormalities are detected and addressed promptly.
3Reliability
If state monitoring and charging determination systems are implemented, then inappropriate charging is prevented, but system complexity increases
Solution Approach 1:
The server device acts as an intermediary between the power storage device and the charging device. It receives battery state information, performs charging suitability determination, and transmits control instructions to the charging device. This intermediary approach centralizes the complexity in a dedicated server, keeping the actual power storage and charging devices relatively simple while achieving reliable charging control.

AI summary
A method is provided that includes: receiving identification information of a power storage device that is connected to a charging device, and a value indicating the state of a storage battery included in the power storage device. The method also includes associating to each other and storing the identification information of the power storage device and the value indicating the state of the storage battery. Additionally, the method includes determining the possibility of charging the power storage device by comparing the received value indicating the state of the storage battery with a value indicating a past state of the storage battery that is stored and corresponds to the received identification information of the power storage device. The method further includes transmitting information indicating the determined possibility of charging the power storage device to at least one of the charging device and the power storage device.
