Detachable Battery Authentication for Theft Prevention and Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management systems for detachable batteries in devices, such as work machines or vehicles, lack the ability to dynamically update identification information, leading to inconvenience and increased burden on operators, particularly in sharing systems where batteries are rented or shared among multiple users, and fail to prevent unauthorized use or theft effectively.
Innovation Solution
A management system and battery configuration that includes a battery-side storage unit for device identification information and a control unit for authenticating power supply based on matching authentication information, with a management unit capable of storing or erasing this information based on user identification, allowing secure and flexible use across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If verification is performed between battery and device using fixed identification information, then theft prevention is improved, but adaptability to changing situations deteriorates
Solution Approach 1:
The identification information in the battery is made dynamically changeable through a management unit that can update the device identification information stored in the battery. This allows the system to maintain security verification while adapting to changing usage situations, such as when devices are no longer used or batteries are reused for different devices.
Solution Approach 2:
A management unit is introduced as an intermediary component that mediates between the security verification requirement and the need for flexibility. This management unit stores and manages the device identification information in the battery, enabling updates without requiring changes to the battery hardware itself or complex reconfiguration procedures.
2Reliability
If identification information is fixed and cannot be changed on user side, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system enables users to perform identification information updates themselves through the management unit, eliminating the need for business operators to manually configure each battery-device pairing. Users can independently adapt the battery to their current device needs while maintaining security through the authenticated update process.
3Reliability
If business operator manages all identification information, then security control is improved, but productivity deteriorates
Solution Approach 1:
The management unit is pre-configured in the battery to handle identification information management. This preliminary setup enables automatic or user-initiated updates without requiring business operator intervention for each change, allowing the system to respond immediately to changing situations while maintaining security through the pre-established management framework.

AI summary
This management system manages a battery mounted on a device in a detachable manner. The battery has a battery side storage unit for storing a unique device ID of the device and a control circuit. While the control circuit supplies the power of the battery when determining that a use time authentication ID obtained from the device and the device ID are consistent with each other, the control circuit stops supplying the power of the battery when determining that the use time authentication ID and the device ID are inconsistent with each other. The management system is also provided with a management unit for storing or deleting the device ID into or from the battery side storage unit when obtaining a user ID.
