Removable Battery Charging Control Under Defect and Power Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery sharing systems face challenges in ensuring appropriate charging of removable batteries, particularly due to potential defects in battery lots and varying electrical power availability at charging stations, which can lead to inefficient charging and rental practices.
Innovation Solution
A system comprising a battery use system, a charging device, and a server that communicate to manage the charging and detachment of removable batteries based on identification information, preventing charging or detachment of defective batteries and optimizing charging according to available electrical power, using a network of accommodation units, communicators, and controllers to determine availability and control charging processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a returned battery is charged and rented out without verification, then charging efficiency is high, but defective batteries may be distributed to users
Solution Approach 1:
The system performs preliminary verification of battery identification information before charging. The charging device acquires identification information of the battery, transmits it to the server, receives availability determination, and only then controls charging. This preliminary check prevents defective batteries from being charged and rented out, resolving the contradiction between charging efficiency and battery quality reliability.
2Productivity
If all accommodation units charge batteries simultaneously, then battery availability is high, but power consumption exceeds available electrical power
Solution Approach 1:
The system dynamically controls charging based on available electrical power. The charging device determines the number of accommodation units that can be operated based on available power, and the server determines availability of charging/detachment for each unit. This dynamic adjustment allows the system to maximize battery availability while staying within power constraints, resolving the contradiction between productivity and energy consumption.
3Speed
If the charging device operates without server verification, then operation speed is high, but defective batteries cannot be identified
Solution Approach 1:
The system implements feedback control where the charging device acquires battery identification information, transmits it to the server, receives availability determination feedback, and then controls charging accordingly. This feedback loop ensures rapid operation while maintaining reliable defect detection, resolving the contradiction between speed and reliability.

AI summary
A battery use system includes a battery removably mounted on an electric power device, a charging device configured to charge the battery, and a server configured to communicate with the charging device. The charging device is configured to transmit the identification information of the battery accommodated in the accommodation unit to the server via a first communicator and control charging of the battery and/or detachment of the battery on the basis of reception information received by the first communicator from the server. The server is configured to determine whether or not the charging of the battery and/or the detachment of the battery accommodated in the accommodation unit are available on the basis of the identification information received by a second communicator from the charging device and provision information provided from an information provider and transmit transmission information on an availability determination result to the charging device via the second communicator.
