Battery Access Control Using Security Tokens Against Theft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-value batteries used for energy storage are vulnerable to theft due to their expense, necessitating a system that prevents or discourages theft by ensuring only authorized use.
Innovation Solution
A battery security system that employs a battery management system (BMS) to manage a security key or token, verifying ownership and preventing operation if stolen, using a control system to communicate with the BMS and remotely deactivate batteries if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If batteries are made expensive to store energy, then energy storage capability is improved, but vulnerability to theft increases
Solution Approach 1:
The patent applies preliminary anti-action by implementing a security system that proactively prevents theft before it occurs. The BMS verifies security tokens and communicates with a security server to authenticate batteries, creating preventive measures that deter thieves from attempting to steal expensive batteries used for energy storage.
Solution Approach 2:
The patent uses an intermediary approach by introducing a security server as a mediator between the battery management system and the battery. The security server verifies security tokens and provides authentication, creating an intermediate layer that protects the expensive battery from theft while allowing legitimate energy storage operations.
2Reliability
If a security system is added to prevent theft, then theft prevention capability is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by designing the security system to perform multiple functions within the existing battery management infrastructure. The BMS both manages battery operations and handles security verification, while the security server also performs other battery management functions, reducing overall system complexity despite adding theft prevention capabilities.
Solution Approach 2:
The patent implements self-service by enabling the battery management system to autonomously verify security tokens and communicate with the security server without requiring external intervention. The system automatically authenticates batteries and manages security protocols, reducing complexity by eliminating the need for separate manual security management processes.

AI summary
Example battery security systems and methods are described. In one implementation, a control system manages access to at least one battery and a battery module controls access to energy stored in a battery core. The battery module also includes a battery operation manager that controls operation of the battery module and a security manager that controls security of the battery module by storing security keys, storing tokens, retrieving security keys, retrieving tokens, validating security keys, validating tokens, or communicating with the control system for validation of the battery module.
