Key Findings

  • 01EV battery packs, despite design variations, share common disassembly structures.
  • 02Disassembly can be logically segmented into two main stages and six distinct blocks.
  • 03Understanding precedencies and criticalities within these blocks is essential for efficient disassembly.
02

Application

Design takeaway

Design electric vehicle battery packs with a clear, sequential disassembly process in mind, prioritizing ease of access to internal components for repair, reuse, or recycling.

How to apply

When designing or evaluating EV battery packs, map out the disassembly sequence, identify critical components, and assess the tools and time required for each step.

Project actions

  • 01When researching a product for disassembly, look for commonalities across different models.
  • 02Clearly define the stages and individual steps involved in taking a product apart.
03

Method & Evidence

AimTo identify and analyze critical disassembly stages and precedencies within electric vehicle battery packs to facilitate the application of circular economy strategies.
MethodComparative analysis of disassembly procedures
ProcedureThe study analyzed the structure and disassembly procedures of four different electric vehicle battery pack models, identifying commonalities and critical steps. Six key disassembly blocks were defined and grouped into two main stages: initial external component removal and internal component extraction.
ContextElectric vehicle battery pack design and end-of-life management

Variables

IVBattery pack model, design features affecting disassembly
DVNumber of disassembly stages, number of disassembly blocks, criticalities in disassembly procedure
CVType of battery technology (e.g., lithium-ion), general purpose of the battery pack
04

Strengths & Limitations

Strengths

  • +Provides a structured framework for analyzing product disassembly.
  • +Identifies practical stages and blocks applicable to complex products.

Limitations

The complexity of some products may make a full, safe disassembly difficult without specialized tools or knowledge.

Reliability & validity

The findings are based on a comparative analysis of specific models, and the generalizability to all EV battery packs would require a broader sample size. The identification of 'criticalities' is subjective and could vary based on the expertise of the dissector.

Think critically

How might the identified disassembly stages be adapted for products with significantly different internal structures, such as consumer electronics or furniture?

05

Design Principles

"Design for Disassembly (DfD) in battery systems should follow a structured, multi-stage approach to maximize material recovery and circularity."

As electric vehicles become more prevalent, the end-of-life management of their battery packs presents a significant challenge and opportunity. Designing for efficient disassembly directly impacts the economic viability of repair, remanufacturing, and recycling, thereby supporting sustainability goals.

06

What This Means for Your Design

To make electric car batteries easier to fix or recycle, we need to design them so they can be taken apart in a specific, step-by-step way.

How to use in your project

  • 1.Use the identified disassembly stages and blocks as a framework for analyzing the disassembly of your chosen product.
  • 2.Discuss how the design of your product facilitates or hinders these stages.
