Battery Locking Pin and Security Plate for EV Theft Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicles lack effective protection for their battery modules, making them susceptible to theft as they are often left unprotected.
Innovation Solution
A security system comprising a battery enclosure with fastener apertures, a security plate with aligned fastener holes, elongated fasteners, and a blocking pin with a lock mechanism that prevents access to the fasteners, ensuring the battery enclosure is securely attached to the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery enclosure is left unprotected on an electric vehicle, then the vehicle structure remains simple and easy to manufacture, but the battery becomes susceptible to theft and unauthorized removal
Solution Approach 1:
The security plate is nested within the battery enclosure structure, with the pin mechanism nested within the security plate. The pin passes through the security plate to engage with the vehicle frame, creating a nested security system that integrates multiple protective functions within a compact hierarchical structure.
Solution Approach 2:
The security plate and pin mechanism are pre-installed on the battery enclosure before final assembly to the vehicle. The pin is designed to be inserted through the security plate and engaged with the vehicle frame in advance, creating a preliminary security barrier that prevents unauthorized removal before the battery is even mounted.
2Object-affected harmful factors
If a blocking pin with lock mechanism is added to prevent fastener access, then theft protection is improved, but the device complexity and number of components increases
Solution Approach 1:
The security plate combines multiple functions into a single component: it serves as a mounting surface for the pin, provides structural reinforcement for the battery enclosure, and creates the locking interface with the vehicle frame. The pin itself combines the blocking function with the locking function, eliminating the need for separate components.
Solution Approach 2:
The security plate serves multiple purposes: it reinforces the battery enclosure structure, provides a mounting surface for the pin mechanism, and creates a locking interface with the vehicle frame. The pin serves both to block fastener access and to lock the battery in place when engaged with the vehicle frame.
3Strength
If elongated fasteners are used to attach the battery enclosure to the vehicle, then the battery is securely attached, but the fasteners become accessible and removable without special protection
Solution Approach 1:
The security plate acts as an intermediary between the battery enclosure and the vehicle frame, intercepting access to the fasteners. The pin mechanism serves as a mediator that blocks the path to the fasteners, requiring the pin to be removed or damaged before the fasteners can be accessed, thus protecting the attachment strength while reducing fastener accessibility.

AI summary
Described herein are systems and apparatuses for securing and locking a battery or battery enclosure to a vehicle. In general, a vehicle may include a planar body mounted to any number of wheels, tracks, wings or flotation devices. In a preferred embodiment, the security device comprises a security plate and a locking pin system is used to secure the battery to any vehicle. The security plate is positioned between the fastener heads and the battery enclosure and has an opening for the locking pin to slide through. Once the pin is inserted into security plate the pin lock secures the pin in place and prevents removal of the battery or battery enclosure from the vehicle.
