Solution Overview

Problem

Existing EV charging stations are fixed and not easily relocatable, requiring complex installation and relocation processes due to their fixed power connections.

Innovation Solution

A transportable microgrid/nanogrid station with a cabinet structure that includes a battery storage area, item storage, and wheels, equipped with connectors for easy power source connection and disconnection, allowing plug-and-play functionality and relocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If EV charging stations are made fixed with complex power connections, then power supply stability is improved, but relocation capability deteriorates

Engineering Contradiction:
Improvepower supply stabilityVSAvoidrelocation capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The charging station is divided into modular components including a cabinet unit with battery storage, a separate power connection system with connectors, and an item storage section. This segmentation allows the power connection components to be easily disconnected and reconnected at different locations, enabling relocation while maintaining stable power supply through standardized connectors.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power connection system is designed to be dynamic rather than fixed, with connectors that can be easily attached and detached. The cabinet is equipped with wheels for mobile movement, and the power cables are designed to accommodate movement and repositioning, allowing the charging station to adapt to different locations while maintaining reliable power delivery.

Inventive Principle:
Principle #15Dynamics

2Reliability

If EV charging stations are made fixed with complex installation processes, then power connection reliability is improved, but installation complexity increases

Engineering Contradiction:
Improvepower connection reliabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The power connectors and cables are pre-configured and pre-tested during manufacturing to ensure reliable connections. The cabinet is pre-assembled with battery storage and charging components integrated, so that upon arrival at the installation location, the system requires minimal assembly and can be quickly connected to power sources and vehicles, reducing on-site installation complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Standardized connectors serve as intermediaries between the charging station and external power sources or vehicles. These standardized interfaces simplify the connection process by providing universal compatibility, eliminating the need for custom wiring or complex installation procedures while maintaining reliable electrical connections.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If EV charging stations are made mobile with simple connections, then relocation ease is improved, but power connection stability deteriorates

Engineering Contradiction:
Improverelocation easeVSAvoidpower connection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The charging station incorporates mobile elements such as wheels on the cabinet and flexible power cables that accommodate movement. These dynamic components are designed to maintain stable electrical connections during and after relocation, with connectors that lock securely and cables that can handle movement without compromising connection integrity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system is segmented into a mobile cabinet unit and separate power connection components. This segmentation allows the cabinet to be easily moved to different locations while the power connection components can be securely attached or detached as needed, maintaining connection stability through standardized, robust connector designs that ensure reliable power transfer.

Inventive Principle:
Principle #1Segmentation

AI summary

Systems and apparatus for implementing a mobile energy system. In one aspect, a mobile energy system includes a cabinet having an interior space defined by an outer surface of the cabinet, where the interior space can include a battery storage area configured to receive a battery energy storage system having at least 2kWh of storage capacity. The mobile energy system can also include an item storage area configured to receive and store one or more other items, a connector configured to connect a battery energy storage system located in the battery storage area to an external power source, and a charging cable configured to connect the battery energy storage system to a charging port of an electric vehicle.
