Vehicle Battery Charging Safety Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery charging systems for vehicles, particularly industrial trucks, face challenges in ensuring safe and efficient charging due to the risk of damage from careless handling, where the vehicle can be driven off while still connected to a charger, requiring complex and time-consuming manual disconnection procedures.
Innovation Solution
A battery system with a safety device that detects mechanical charging connections to interrupt the energy supply, using a mechanical actuating element and electronic switching elements to prevent current flow, allowing for safe and ergonomic charging by ensuring the vehicle component is disconnected during charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual disconnection procedures are used to prevent damage during charging, then safety is improved, but operation time and complexity increase
Solution Approach 1:
The charging component is designed to automatically disconnect from the vehicle's electrical system before the charging process begins. This preliminary disconnection action prevents any risk of damage during charging while eliminating the need for manual intervention, thus resolving the contradiction between safety and operation time.
Solution Approach 2:
The charging component具备 self-service capability by automatically managing its own connection and disconnection from the vehicle's electrical system. The component detects the charging state and autonomously interrupts the electrical connection, eliminating the need for manual operations and reducing both time and complexity while maintaining safety.
2Duration of action of moving object
If the battery remains connected to the vehicle during charging, then operational continuity is improved, but risk of damage increases
Solution Approach 1:
The electrical connection system is segmented into two independent parts: a permanent connection for the battery to the vehicle's electrical system, and a detachable charging component for external charging connections. This segmentation allows the battery to remain connected to the vehicle while the charging component can be safely disconnected during charging, eliminating the risk of damage while maintaining operational continuity.
Solution Approach 2:
The charging component acts as an intermediary between the battery and external charging devices. It provides a dedicated charging connection point that is electrically isolated from the vehicle's main electrical system, allowing charging to occur without risking damage to the vehicle's electrical components while the battery remains part of the vehicle's power system.
3Reliability
If complex safety measures are implemented to prevent careless handling, then protection is improved, but device complexity increases
Solution Approach 1:
The charging component automatically detects when it is connected to a charging device and autonomously interrupts its electrical connection to the vehicle's electrical system. This self-service safety mechanism eliminates the need for complex manual safety procedures or additional safety devices, providing protection while maintaining simplicity.
Solution Approach 2:
The patent replaces complex mechanical safety mechanisms with an electronic detection and control system. The charging component uses electrical signals to detect connection status and automatically control the disconnection, substituting mechanical safety measures with a more reliable and simpler electronic system.
