Modular Vehicle Battery Assembly for Selective Swapping

Solution Overview

Problem

Existing battery swapping systems face inefficiencies due to the replacement of whole large battery packs, often without deep discharge, leading to power waste and increased difficulty in swapping, especially with large dimensions.

Innovation Solution

A battery assembly comprising a plurality of detachable batteries with mounting structures, allowing for flexible configuration and separate replacement, reducing the need for all batteries to be mounted, and enabling compatibility with various vehicle models and scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a whole large battery pack is replaced, then battery swapping is performed, but power is wasted due to replacement without deep discharge and swapping difficulty increases

Engineering Contradiction:

Improvebattery swapping efficiencyVSAvoidpower waste

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The battery pack is divided into multiple independent battery modules that can be separately mounted and replaced. Each battery has its own mounting structure allowing individual attachment and detachment from the vehicle, enabling selective replacement of only the discharged batteries rather than the entire pack.

Inventive Principle:

Principle #1Segmentation

2Productivity

If a whole large battery pack is replaced, then battery swapping is achieved, but swapping difficulty increases due to large dimensions

Engineering Contradiction:

Improvebattery swapping efficiencyVSAvoidswapping difficulty

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The battery pack is divided into multiple independent battery modules that can be separately mounted and replaced. Each battery has its own mounting structure allowing individual attachment and detachment from the vehicle, enabling selective replacement of only the discharged batteries rather than the entire pack.

Inventive Principle:

Principle #1Segmentation

3Quantity of substance

If all batteries are mounted to the vehicle, then complete battery capacity is provided, but vehicle load increases

Engineering Contradiction:

Improvebattery capacityVSAvoidvehicle load

Core Design Contradiction:

Quantity of substanceVSWeight of moving object

Solution Approach 1:

The battery pack is divided into multiple independent battery modules that can be separately mounted and replaced. Each battery has its own mounting structure allowing individual attachment and detachment from the vehicle, enabling selective replacement of only the discharged batteries rather than the entire pack.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of mounting all batteries to the vehicle, only the necessary number of batteries required for the intended usage scenario are mounted. This partial mounting approach reduces vehicle load while still providing sufficient battery capacity for the vehicle's operational needs.

Inventive Principle:

Principle #16Partial or excessive action
