  1. Assessment of performances of various lithium-ion chemistries for Plug-in Hybrid Electric Vehicles Noshin Omar, Joeri Van Mierlo, Peter Van den Bossche Belgian platform on electric vehicles # 3 noshomar@vub.ac.be slide 1

  2. Overview • Introduction • Battery requirements for PHEV • Test methodology • Ragone plot • Battery characteristics • Economic and life cycle considerations • Summary and conclusions

  3. Introduction • Plug-in hybrid electric vehicles have received considerable attention due to: • Reduce gasoline consumption • Decrease green house gas emissions

  4. Battery requirements Source; 1. A. Pesaran, “ Battery Requirements for Plug-In Hybrid Electric Vehicles –Analysis and Rationale”, EVS23, 2007, California, USA 2. P. Van den Bossche, “SUBAT: An assessment of sustainable battery technology”, Journal of Power Sources, 2005 3. J.

  5. Test Methodology

  6. Ragone plot • LNMCO based cells: 126 – 149Wh/kg • LFP based cells: 75 – 118Wh/kg • LNCA: 90Wh/kg • The situation regarding the power density is not clear due to the wide range Power density: Max. Current rate, 50% SoC, 10 sec. Pulse

  7. Energy and discharge performances

  8. Power performances

  9. Charge capabilities

  10. Life cycle LFP NMC NCA

  11. SoC determination

  12. Peukert and SoC

  13. Summary

  14. Conclusions • LNMC based cells: • Pro: higher energy, energy efficiency, SoC determination • Con: thermal stability, cost • LFP based cells: • Pro: high power density, favourable thermal performances, cost • Con: low energy density, lower energy efficiency, SoC determination • LNCA in the postive electrode: • Pro: high energy efficiency, SoC determination • Con: low energy density, power density, less thermal performances, cost, life cycle • Control strategy in PHEV application is a key issue
