VW Looking to Reduce Battery Costs by 66% with Singe Cell Design

Volkswagen Group may shift to a single lithium ion battery cell design for all of its electrified vehicles.

Heinz-Jakob Neusser, VW's board member in charge of development, says the group is targeting a 66 percent cost reduction with a design that would be packaged into modules customized for each vehicle.

"We have a clear understanding in the group of a common cell," Neusser said during a roundtable at the auto show here. "That means each member of the group, each brand, uses the same cell. Otherwise, we cannot get the synergies out of this development."

Volkswagen currently uses multiple types of lithium ion cells. For example, Panasonic supplies cells for the e-Golf, Golf GTE plug-in hybrid and Audi A3 e-tron, while Samsung supplies cells for the upcoming Passat GTE and Audi electrified vehicles.

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.

Volkswagen plans to decide in the first half of this year whether new battery technology under development at U.S. startup QuantumScape Corp. is ready for use in its electric cars.
