EFB and Heat

EFB and Heat: High Temperature Durability Tests for Advanced Lead 12V Batteries
When: 22-23 May 2019
Where: Bruges, Belgium
The Consortium for Battery Innovation (formerly ALABC) with CENELEC are holding a workshop bringing together technical global experts from the advanced lead battery and automotive industries to discuss. This follows meetings held Kloster Eberbach in 2017 and Alcalá de Henares in 2018.
The advanced lead 12V battery workshop will be followed on 23 May (3.30pm-6pm) and 24 May (9am-3pm) by a Consortium for Battery Innovation (CBI) European Technical Workshop, to discuss the launch of new projects to be funded under the 2019 CBI technical program.
The workshop takes place at the Crowne Plaza Hotel in the ancient city centre of Bruges, Belgium.
Registration will open on 4 March 2019. To secure your place and obtain more information contact Maura McDermott (mcdermott@ila-lead.org).
The “EFB and Heat” Workshop will trigger discussion and establish co-operation between battery experts working in all parts of the value-added chain.
Compact overview talks and plenary discussions in the following areas:
  • Battery data from micro-hybrid vehicle application in hot climate, including field simulation testing
  • Improved understanding of parasitic reactions in modern automotive batteries: gas evolution, oxygen cycle, corrosion
  • New test methods and standards: high temperature durability, microcycling (stop/start) durability, dynamic charge acceptance
  • From small test cells to real batteries: How to evaluate performance and durability through R&D

Breakout sessions out of which participants will select their key topics:

Deep dive of high temp. test & field data

  • CENELEC draft key life test and reference drive cycles
  • Field tests by OEMs and suppliers
  • Comparison of EFB and AGM with and without “high DCA” additive

Stop/Start micro-cycle durability testing

  • Review of MHT trial runs with parameter variation
  • Validation of CENELEC draft Micro-Hybrid Test (MHT) v2.0
  • Can we achieve global harmonization?

Measuring gas evolution directly

  • First user workshop for CBI’s electronic gas analysis system (eGAS) 
  • Laboratory applications from Tafel slopes to drive cycles
  • In-vehicle applications
Water loss and oxygen cycle in EFB real-world operation
  • Explaining the discrepancy between water loss rates during steady-state overcharging versus during microcycling 
  • Experimental investigation of the oxygen cycle in EFB
  • What are implications for durability test methods?
Corrosion under PSoC microcycling conditions
  •  Localized results from lab test cells and actual 12V batteries
  • How to measure corrosion during tests: in-situ (relative comparison) and ex-situ (sample preparation effects?
  • Recent results from ongoing XRD study - can it be used for corrosion?
Measuring DCA and water loss in test cells
  • Examples of test cell designs; ALABC/CBI cell-test manual 
  • How to scale down “fresh” and “run-in” DCA tests?
  • Can we test high temperature durability in small lab cells?
The workshop will begin on Wednesday 22 May with a working lunch and finish in the early afternoon of Thursday 23 May.
