Solution Overview

Problem

Existing charging pile systems face inefficiencies and increased costs due to the need for high-power installations that waste resources when low-power vehicles are charged, and the inflexibility and maintenance difficulties of underground cable installations.

Innovation Solution

A charging pile system where charging plugs with both power and communications cables are used to interconnect existing charging piles, allowing power to be shared dynamically based on load requirements, enabling cost-effective and efficient power distribution by serially connecting idle piles when a single pile's output is insufficient.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If high power charging piles are designed to meet high power vehicle requirements, then the power requirement of high power vehicles is satisfied, but resources are wasted when low power vehicles use the charging pile

Engineering Contradiction:

Improvecharging powerVSAvoidresource waste

Core Design Contradiction:

PowerVSLoss of energy

Solution Approach 1:

The charging pile system dynamically adjusts its power output based on the actual charging requirements of connected vehicles. The controller monitors the vehicle type and power needs, then modulates the power delivery accordingly, allowing a single charging pile to serve both low-power and high-power vehicles efficiently without permanent over-provisioning

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The charging pile is designed with multi-functionality to accommodate different vehicle types and power requirements. By integrating dynamic power adjustment capabilities and universal charging interfaces, the system can serve multiple vehicle categories (low-power cars and high-power buses) with a single charging pile, eliminating the need for separate dedicated charging stations

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Power

If high power charging piles are installed to meet high power vehicle requirements, then the power requirement is satisfied, but installation space requirements increase and installation flexibility decreases

Engineering Contradiction:

Improvecharging powerVSAvoidinstallation flexibility

Core Design Contradiction:

PowerVSAdaptability or versatility

Solution Approach 1:

The charging pile employs dynamic power management that allows it to adapt its operational characteristics based on the connected vehicle's requirements. This dynamic capability enables the same physical installation to serve different power levels, increasing installation flexibility without requiring multiple dedicated high-power installations

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The charging pile design incorporates universal functionality that allows it to operate effectively in various installation environments and serve different vehicle types. The system can deliver appropriate power levels for both low-power cars and high-power buses from the same installation, enhancing adaptability to different spatial constraints

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If power cables and communications cables are installed under the ground, then cable protection is improved, but construction difficulty increases and maintenance becomes difficult

Engineering Contradiction:

Improvecable protectionVSAvoidconstruction difficulty

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The system segments the cable routing into separate functional paths, with power cables and communications cables routed through different channels or layers. This segmentation allows for easier identification and maintenance of specific cable types while maintaining protection, reducing construction complexity compared to bundled underground installation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary protective structure or routing mechanism that separates power and communications cable paths. This intermediary approach provides protection for both cable types while maintaining accessibility for maintenance, avoiding the need for complex underground trenching and layout

Inventive Principle:

Principle #24Intermediary (Mediator)

4Power

If multiple charging piles are cascaded to charge high power vehicles, then the power requirement is met, but the system complexity and cable layout requirements increase

Engineering Contradiction:

Improvecharging powerVSAvoidsystem complexity

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

The patent merges multiple charging pile functions into a single integrated charging pile with dynamic power adjustment capabilities. Instead of cascading multiple separate charging piles to achieve high power output, the system combines control functions and power delivery in one unit, reducing system complexity while maintaining the ability to meet high power requirements when needed

Inventive Principle:

Principle #5Merging (Combining)
