Solution Overview

Problem

Existing battery rental systems face a shortage of rentable batteries due to the requirement that only fully charged batteries can be rented, leading to inefficiencies and increased operational costs for service providers.

Innovation Solution

An information processing method that calculates the power amount of a battery at the rental start time based on its deterioration degree, charging rate, and initial full charge capacity, allowing for the rental of batteries with power amounts less than the current full charge capacity, and calculates a rental fee accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If only fully charged batteries are rented out, then battery quality and reliability are ensured, but the number of rentable batteries decreases causing shortage

Engineering Contradiction:

Improvebattery reliabilityVSAvoidnumber of rentable batteries

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent changes the rental criterion from requiring 100% charge to allowing any charge level above 0%. The system calculates remaining power based on initial capacity, charge rate, and deterioration degree, then rents batteries based on their actual remaining power rather than requiring full charge. This parameter change enables more batteries to be rentable while maintaining reliability through power amount verification.

2Quantity of substance

If batteries with less than full charge are rented, then the number of rentable batteries increases, but rental fee calculation complexity increases

Engineering Contradiction:

Improvenumber of rentable batteriesVSAvoidrental fee calculation complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The system performs preliminary calculation of the remaining power amount before rental decision-making. By calculating the remaining power based on initial capacity, charge rate, and deterioration degree in advance, the system simplifies the rental fee calculation process. The rental fee is then determined based on this pre-calculated remaining power amount, avoiding complex real-time calculations during the rental transaction.

3Productivity

If more batteries are made rentable, then battery availability improves, but operational costs for service providers increase

Engineering Contradiction:

Improvebattery availabilityVSAvoidoperational costs

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The patent implements dynamic rental fee calculation based on the actual remaining power amount of each battery. Instead of charging a fixed fee or requiring full charge, the system calculates rental fees proportionally based on remaining capacity. This allows batteries with partial charge to be rented at reduced fees, increasing availability while maintaining operational cost efficiency through proportional pricing.

AI summary

A server acquires deterioration degree, a charging rate, and initial full charge capacity of a battery pack mounted on the electric mobile object at a rental start time of the battery pack, calculates a power amount of the battery pack at the rental start time based on the deterioration degree, the charging rate, and the initial full charge capacity, calculates a rental fee of the electric mobile object incorporating a battery pack having a power amount less than current full charge capacity or a rental fee of a battery pack having a power amount less than current full charge capacity based on the power amount, and outputs the rental fee.
