5. 4. Development of a Novel Method for Lithium-Ion Battery Testing on Heavy-Duty Vehicles

   Författare :Pontus Svens; Mårten Behm; Göran Lindbergh; Per Alvfors; Anders Malmqvist; KTH; []
   Nyckelord :Lithium-ion battery; HEV; field testing; heavy-duty vehicles;

   Sammanfattning : Increasing demands for lower environmental impact from vehicles, including heavy-duty vehicles, have driven several vehicle manufacturers to consider adding hybrid electrical vehicles (HEV’s) to the product portfolio. Present research on batteries for HEV’s is mainly focused on lithium-ion battery chemistries, since lithium-ion batteries has the most promising technical potential compared to other types of batteries.
