Solution Overview

Problem

Traditional electric vehicle charging methods either charge based on the charging period or the power used, leading to unfair billing and inefficiencies, particularly when load balance adjustments are needed, which can affect specific charging processes.

Innovation Solution

A charging fee management system that operates in multiple modes, calculating fees based on both charging period and power usage, allowing for dynamic power adjustments and Time Of Use (TOU) rates, ensuring fair billing and improved flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If charging fee is calculated based on charging period, then billing simplicity is improved, but fairness is worsened when load balance adjustment affects specific charging processes

Engineering Contradiction:

Improvebilling simplicityVSAvoidbilling fairness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The billing system dynamically adapts by switching between different charging methods based on operation modes. The system can calculate fees based on charging period in the first operation mode or based on power usage in the second operation mode, ensuring both simplicity and fairness are maintained under different conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the billing parameter from fixed charging period-based calculation to flexible charging method selection. By implementing different charging methods corresponding to different operation modes, the system can adjust billing parameters to maintain fairness while preserving operational simplicity.

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If traditional fixed rate charging method is used, then charging process stability is improved, but system flexibility is worsened

Engineering Contradiction:

Improvecharging process stabilityVSAvoidsystem flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The charging device implements dynamic operation mode switching between first operation mode and second operation mode, each with its own charging method. This dynamic capability allows the system to maintain stability within each mode while providing flexibility to adapt to different charging scenarios and conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes from fixed rate charging to multiple charging methods that can be selected based on operation modes. This parameter change enables the system to maintain stable charging processes within each mode while providing the flexibility to switch between different charging approaches based on system conditions and requirements.

Inventive Principle:

Principle #35Parameter changes

AI summary

A charging fee management method for electric vehicles for use in a charging device is provided, wherein the charging device can be operated in a plurality of operation modes. First, a charging request for charging an electric vehicle is received. Then, the charging device is controlled to perform a charging process for the electric vehicle according to the charging request, and calculate a charging fee for the charging process, wherein the charging fee is calculated based on charging data during the respective operation mode of the charging device and a respective charging method for each operation mode.
