Electric Telehandler Battery Swap Compartments for Continuous Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art electric telehandlers face limitations in closed environments and town centers due to insufficient battery energy and recharging challenges, leading to interrupted operations and reduced efficiency.
Innovation Solution
An electric telehandler with replaceable batteries housed in accessible compartments, allowing for seamless battery swapping and continuous operation using the energy from the second battery while the first is recharged, with features like guide means, locking mechanisms, and electronic current adjustment for efficient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the telehandler uses a single battery system, then the device complexity is reduced, but the operating duration becomes insufficient for completing programmed work
Solution Approach 1:
The battery system is segmented into multiple replaceable battery packs (first battery and second battery) that can be independently exchanged. Each battery pack is contained in a separate compartment, allowing the operator to swap batteries without replacing the entire power system, thus extending operating duration while managing complexity through modular design
Solution Approach 2:
The system changes the parameter of energy availability by switching between multiple battery packs. The control unit manages power distribution between batteries, allowing the telehandler to maintain continuous operation by switching to a charged battery when one is depleted, effectively extending the operational parameter without proportionally increasing system complexity
2Duration of action of moving object
If the telehandler is equipped with multiple batteries and compartments, then the operating duration is extended, but the ease of operation is reduced due to complicated battery replacement procedures
Solution Approach 1:
Battery packs are pre-charged before use, and the system is designed with pre-positioned compartments and guide means. The locking mechanisms and guide rails are pre-configured to align with the battery geometry, allowing operators to perform simple insertion and extraction actions without complex assembly procedures, thus maintaining ease of operation while extending duration through multiple batteries
Solution Approach 2:
The battery replacement function is extracted as a simple mechanical insertion/extraction operation. The compartment design separates the battery replacement task from the overall telehandler operation, allowing batteries to be swapped independently through accessible openings with guide means and locking mechanisms, making the procedure simple and quick while enabling extended operation through multiple battery packs
3Object-affected harmful factors
If the telehandler operates in closed environments or restricted zones, then environmental compliance is improved, but productivity is reduced due to interruptions for recharging
Solution Approach 1:
The telehandler maintains continuous useful action through multiple battery packs. When one battery is depleted during operation in restricted environments, the operator can quickly swap to a pre-charged battery without halting work activities. This ensures uninterrupted productivity while maintaining environmental compliance by continuing to operate electrically powered equipment in zones where fossil fuel vehicles are restricted
Solution Approach 2:
The system implements a battery rotation strategy where depleted batteries are temporarily 'discarded' from service and replaced with charged ones. The depleted batteries can then be recovered, recharged externally, and returned to service, creating a continuous cycle that maintains productivity in restricted environments without interruption for recharging during operation
