Transponder-Embedded Plug Connection for Battery Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric plug connections for industrial truck batteries lack automated identification and adaptation of charge/discharge characteristics, leading to inefficient battery usage and lifetime, especially in rental or leasing scenarios where special operating states are not accounted for.
Innovation Solution
Incorporating a transponder in the plug connection's battery end to store identification data, allowing for automatic battery identification using a reader, which enables setting and adapting charge characteristics, and optionally connecting to a control unit for automatic parameter adjustment, and using readers to determine optimal charging devices or track battery history for cost calculation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a transponder with identification data is integrated into the plug connection, then automatic battery identification and adaptation of charge characteristics is enabled, but device complexity increases
Solution Approach 1:
The transponder is integrated directly into the plug connection component itself, merging the identification function with the existing electrical connection structure. This eliminates the need for separate identification devices and reduces overall system complexity despite adding automation capabilities.
Solution Approach 2:
The plug connection is designed to serve multiple functions: electrical connection, data transmission through coding pins, and battery identification through the integrated transponder. This multi-functionality allows a single component to handle multiple tasks that would otherwise require separate devices.
2Device complexity
If charge characteristics are manually set based on operator knowledge, then device complexity remains low, but battery efficiency and lifetime deteriorate
Solution Approach 1:
The system reads battery identification data from the transponder and uses this information to automatically adapt charge characteristics. This feedback mechanism ensures that charging parameters are optimized based on the specific battery type, improving efficiency and lifetime without requiring complex manual intervention.
Solution Approach 2:
The charging system automatically identifies the battery type and selects appropriate charge characteristics without requiring operator knowledge or manual configuration. The system serves itself by using the transponder data to configure optimal charging parameters, improving reliability while maintaining reasonable complexity.
3Device complexity
If battery identification data is stored in a separate system, then plug connection remains simple, but information loss occurs during battery changes
Solution Approach 1:
The transponder stores battery identification and history data in advance, directly on the battery or its connector. This preliminary action ensures that all necessary information is already available and attached to the battery itself, preventing any information loss during battery changes or transfers between vehicles.
