Electromobility+, Administrative and Scientific Report 2014

Project advancement: Activities have been started in all Work Packages with different level of progress.

Electromobility+, Administrative and Scientific Report 2014 – Publishable Summary

Within the reporting period activities in all work packages were sustained.

The degradation behaviour of the cells was further investigated. It was ascertained that the higher the depth of discharge, the earlier a nonlinear aging behavior will emerge. It is furthermore the charge cutoff voltage which is presumably responsible for the more fasten degradation of cells. Tests have shown that there is definitely the possibility for mitigation by lowering the load at a certain cell’s state of health. Analysis show good accordance from in-field degraded cells to laboratory cells.
Related to the 2nd life solutions it was identified that the smallest level for an exchange of single units is a modular one since no bigger variation in the single cells’ parameters could be detected in the aged modules.

The activities in the Recycling solution work package lead to the identification and characterization of the components in different types of Li-ion battery packs and cells as well as their contents and individual economic values. A flow sheet of a recycling process for Li-Ion-batteries from EV, a strategy to determine the state of charge of battery cells and a method for discharging the cells were developed. Customers for the different products of the recycling process in dependency of their purity were identified.
For the business models of 2nd Life and recycling solutions for the batteries a reference scenario “Electric Vehicle Use (1 Use) + Home Energy Management Storage (2 Use)” was finalized and implemented in Gabi Software.

Theoretical results about the advantages and limitations of coupling were gained. Basics for the built-up of a small scale pilot plant were accomplished.
Dissemination activities started (conference participation) communication tools were provided. Communication, reporting and regular general assemblies were performed.

The main objective of the project is the development and implementation of a knowledge base on high voltage traction battery deterioration; a safe management structure for EV battery recycling; strategies and technologies for battery re-use and recycling. ABattReLife gathers stakeholders from France, Germany and the Netherlands in order to:

Develop a technology for optimised materials recuperation from battery waste

Create a new management structure for re-using and recycling EV

Set boundary conditions for the use of batteries in the first stage of the life-cycle (tradeoff between the efficiency and lifetime of battery packs)

After an analysis of batteries behaviour and degradation phenomena (WP1), the consortium will assess in parallel the options to use EV batteries in second life applications (WP2) and the recycling technologies solutions at the end of life of the battery (WP3). Once this new knowledge will be structured and available, new value-chain and business models for recycling and re-use should be proposed (WP4) before carrying out a feasibility study and small scale pilot (WP5).

The project should therefore allow: Academic to transfer their knowledge to Industry; Industry to develop a non-existing value chain; users to get more information on battery behaviour; and policy-makers to develop public policies to promote the penetration of EVs into the market
