Substituting new battery technology would impact on vehicle price & efficiency, finds new study
That’s the finding of a major study published today (19th May) by Europe’s automotive and battery industries.
The study concludes that lead-based batteries will by necessity remain the most wide-spread energy storage system in automotive applications for the foreseeable future. Their low cost and unparalleled ability to start the engine at cold temperatures sets them apart in conventional and basic micro-hybrid vehicles, and as auxiliary batteries in all other automotive applications. With regard to overall storage capability and potential for further fuel efficiency improvements, the demand for larger battery systems based on lithium, nickel and sodium will continue to grow through the increased market penetration of vehicles with higher levels of hybridisation and electrification.
Commenting on the findings, Johann-Friedrich Dempwolff, chairman of EUROBAT, the Association of European Automotive and Industrial Battery Manufacturers, said: ‘Currently all battery technologies have specific performance profiles that serve a well-defined purpose in automotive applications and continue to have an irreplaceable role in reducing CO2 emissions from transport.
‘In particular, this report demonstrates the necessity of maintaining the exemption for lead-based batteries within the EU End of Life Vehicle Directive’s wider ban on lead in light-duty vehicles. The EU’s legislative and regulatory framework should guarantee a fair and technology-neutral competition between battery technologies.’
The report also makes clear that a transition towards other battery types would have significant ramifications for development times and would be expensive to implement effectively. In order to optimise fuel efficiency improvements in each vehicle type, automobile manufacturers need the flexibility to choose the most appropriate batteries from a technical and economic perspective.
