Audi A3 Sportback e-tron

Volkswagen intends to develop a single lithium-ion battery cell design, which would fit into all of the plug-in cars made by the VW Group.

We believe that Volkswagen is referring to geometrical dimensions and maybe general type with universal modules and battery management system, because cell chemistry still could be unique to different suppliers and applications (high energy for BEVs and high power for PHEVs).

For now Volkswagen uses Panasonic batteries in e-up!, e-Golf, Golf GTE and Audi A3 Sportback e-tron. Samsung will supply cells for the upcoming Volkswagen Passat GTE and new Audi models.

Standardization of cell design over many models could bring overall costs down. The target is for 66% reduced costs, but we are not sure at what level (Only costs of design? Or whole modules?).

 "the group is targeting a 66 percent cost reduction with a design that would be packaged into modules customized for each vehicle."

"A single design would enable greater utilization of the group's battery module assembly plant in Braunschweig, Germany. Multiple suppliers could be used to source the single cell design, a spokesman said."

Heinz-Jakob Neusser, VW's board member in charge of development, said:

"We have a clear understanding in the group of a common cell. That means each member of the group, each brand, uses the same cell. Otherwise, we cannot get the synergies out of this development."
