Innovation Solution
An apparatus that includes an enclosure, an interface device connected to a power distribution network, a bellows with a connector to form a weatherproof seal with an energy storage unit, and a cable to transfer energy between the power distribution network and the energy storage unit, allowing for quick and safe connection and disconnection of mobile utility-scale energy storage units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If utility-scale energy storage systems use lithium-ion batteries, then energy efficiency and energy density are improved, but safety issues and transportation difficulties arise
Solution Approach 1:
The system separates the energy storage units from the charging infrastructure, allowing batteries to be transported in a segmented, modular fashion on transporters rather than as a complete charged system. This segmentation enables safe transportation while maintaining high energy efficiency during operation.
Solution Approach 2:
The docking station serves as an intermediary between the power distribution network and mobile energy storage units. It provides a safe interface for charging and discharging, isolating the hazardous charged battery state from transportation and handling operations.
2Reliability
If utility-scale energy storage systems are fixed at a specific location, then safety is improved, but adaptability to meet peak demand at different locations deteriorates
Solution Approach 1:
The system transitions from static fixed installations to dynamic mobile units that can be moved to different locations based on demand. The docking station provides a standardized interface that enables these dynamic relocations while maintaining safety protocols during charging and discharging operations.
Solution Approach 2:
The docking station design with standardized connectors and interfaces enables universal compatibility across multiple locations. This allows the same mobile energy storage unit to serve different grid locations during peak demand periods, providing adaptability while maintaining safety through consistent standardized interfaces.
3Adaptability or versatility
If assembly and disassembly processes are used when moving batteries, then adaptability is improved, but time consumption and complexity increase
Solution Approach 1:
The bellows connectors are pre-configured with standardized interfaces and sealing mechanisms that enable quick connection and disconnection. The weatherproof sealing is pre-engineered into the bellows structure, eliminating the need for complex assembly and disassembly procedures during relocation.
Solution Approach 2:
The cable is nested within the bellows structure, which itself connects to the enclosure. This nested configuration allows the cable to be automatically routed and protected during connection and disconnection, reducing the time and complexity of assembly operations when moving energy storage units.
4Use of energy by moving object
If charged batteries are transported, then energy availability is improved, but safety risks and logistical challenges increase
Solution Approach 1:
The system segments the energy storage into mobile units that can be transported in a charged state on specialized transporters. The bellows connector with weatherproof sealing provides a safe, protected interface during transportation, isolating the charged batteries from environmental hazards while maintaining energy availability.
