Particles contamination in battery and electric vehicles systems: from safety to sustainability

Purpose and goal:

The project aimed to identify key differences in Technical Cleanliness between ICE vehicles and EVs. It focused on detecting harmful particles that cause early EV failures, identifying knowledge gaps, and developing better particle extraction methods and analyses to prevent early damages. Expected results and effects:

The main outcome of this project is a comprehensive Literature Review that examines various aspects of Technical Cleanliness in electric vehicles. This document can serve as a base for larger publicly funded research projects or be used internally by the project partners to develop improved processes and routines for manufacturing durable and sustainable components and systems.

Approach and implementation:

The aim was to explore particle extraction methods for analyzing Technical Cleanliness in batteries and electric motor components. However, it became clear that there was a significant knowledge gap regarding the effects of particles and damage mechanisms under electrified conditions. Consequently, the focus shifted to addressing these gaps before examining Technical Cleanliness methods.

With project partners also interested in how electricity affects damage mechanisms, a report was created, leading to plans for larger projects focused on experimental analyses.
