Biometric Battery Access Control for Electric Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing battery performance and security across multiple electric work vehicles operated by different operators is challenging, especially when batteries are moved between vehicles or rented on a subscription basis.
Innovation Solution
Implementing a biometric identification system that collects and verifies operators' biometric data against a list of authorized personnel, enabling or restricting access to the battery for specific operations such as use, removal, mounting, and charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric identification system is implemented, then battery security is improved, but device complexity increases
Solution Approach 1:
A security device acts as an intermediary between the battery and operators. This device includes a biometric identification device for collecting biometric identifiers, a processor for verifying identifiers against authorized operator lists, and a battery interlock mechanism that physically prevents battery removal or mounting when unauthorized. The intermediary handles all security functions centrally, adding verification steps but maintaining a relatively simple overall system architecture.
2Reliability
If access control is enforced for all battery operations, then battery security is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary biometric verification before allowing any battery operations. The biometric identification device collects the operator's identifier in advance, the processor verifies authorization status beforehand, and only then does the battery interlock mechanism enable physical access. This preliminary action ensures security is established before operations begin, making the actual battery operations simple and straightforward for authorized users.
Solution Approach 2:
The biometric identification system enables self-service authentication where operators independently verify their own identity through the biometric device. The system automatically compares the collected biometric identifier against the stored list of authorized operators and immediately enables or disables battery access without requiring manual intervention from administrators or security personnel for each access attempt.
3Reliability
If biometric verification is required for every access attempt, then battery security is improved, but productivity decreases
Solution Approach 1:
The system replaces manual security verification processes with automated biometric identification and electronic verification. Instead of physical keys, manual authorization checks, or mechanical locking systems requiring human intervention, the patent uses biometric sensors to automatically capture identifiers, electronic processors to instantly verify authorization against stored data, and electronic interlocks to control battery access. This substitution dramatically reduces verification time while maintaining high security standards.

AI summary
A method of securing a battery for an electric work vehicle, the battery comprising a biometric identification device. A biometric identifier is collected from an operator using the biometric identification device. The biometric identifier is checked against a list of authorized operators. In an event that the operator matches an authorized operator from the list of authorized operators, access to the battery is enabled such that the operator is able to use the battery; remove the battery from the electric work vehicle and a charging module; and mount the battery into the electric work vehicle. In an event that the operator does not match an authorized operator from the list of authorized operators, access to the battery is prevented such that the operator is prevented from using the battery; removing the battery from the electric work vehicle and a charging module; and mounting the battery into the electric work vehicle.
