Agricultural Vehicle Remote Battery Switch Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural vehicles face battery discharge and potential fires due to leakage currents when the engine is stopped, and existing solutions that disconnect the battery when not in use render electrical and electronic functions unavailable.
Innovation Solution
A remotely actuable battery switch system using an on-board communication device that can receive signals from a vehicle-independent device, allowing remote control of the energy storage device's power supply, preventing discharge and fires while enabling continued use of electrical consumers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is disconnected from the vehicle electrical system when the vehicle is not in use, then battery discharge and fire risks are prevented, but electrical and electronic functions become unavailable
Solution Approach 1:
The patent implements a dynamic battery switch system that can change its state (connected/disconnected) based on real-time conditions. The control unit receives signals from communication devices and automatically adjusts the battery connection status, allowing the system to be connected when needed for electrical functions and disconnected when safety is the priority, thus resolving the contradiction between safety and availability.
Solution Approach 2:
The patent introduces a control unit as an intermediary between the battery switch and the vehicle electrical system. This control unit processes signals from communication devices and intelligently decides when to connect or disconnect the battery, mediating between the conflicting requirements of battery safety and electrical consumer availability, and enabling automated safety management without manual intervention.
2Reliability
If the battery main switch is manually actuated by the operator, then battery disconnection is achieved, but operator presence is required and remote operation is impossible
Solution Approach 1:
The patent implements a self-service battery management system where the battery switch is automatically controlled based on received signals from communication devices. The system serves itself by autonomously deciding when to connect or disconnect the battery without requiring manual operator intervention, thus achieving reliable battery disconnection while simultaneously improving operation convenience through automation.
Solution Approach 2:
The patent replaces the manual mechanical actuation of the battery switch with an automated electronic control system. The control unit receives electronic signals from communication devices and automatically actuates the battery switch, substituting the mechanical manual operation with an electronic automated system, thereby eliminating the need for operator presence while maintaining reliable battery disconnection.
3Ease of operation
If electrical consumers remain connected during vehicle idle time, then functions remain available, but battery discharge and fire risks increase
Solution Approach 1:
The patent implements a feedback-based battery management system where the control unit continuously monitors signals from communication devices and adjusts the battery connection status accordingly. When the system detects that the vehicle is not in use through received signals, it automatically disconnects the battery to prevent discharge and fire risks, while maintaining function availability when needed, thus resolving the contradiction through continuous feedback and automated response.
