BMW and Samsung SDI plan to expand their supply relationship for EV battery cells. The two companies have signed a memorandum of understanding that includes an increase in quantities delivered as well as further technological development of battery cells.

BMW produces high-voltage batteries for the i3, i8 and other future hybrid vehicles at its plant in Dingolfing, Germany, using Samsung cells. The 60 Ah nickel-cobalt-manganese (NCM) cells used in the BMW i3 offer the industry’s highest volumetric energy density, according to Samsung.

The company is currently developing next-generation batteries with the United States Advanced Battery Consortium, and expects to offer an advanced NCM chemistry cell, with energy density of ~250 Wh/kg, around 2019.

“Our partnership with Samsung SDI is a good example of successful Korean-German cooperation on innovative technologies,” said BMW Board Member Dr. Klaus Draeger. “The battery is a key component in every electric vehicle, since it basically determines the range and performance capabilities of the car. In Samsung SDI, we have chosen a supplier that offers us the best available technology with future-oriented Korean battery expertise.”

“The decision taken in 2009 to choose lithium-ion battery cells from Samsung SDI for the BMW i models was the right one for both companies,” said Sang-Jin Park, CEO of Samsung. “Additional BMW vehicles will also be equipped with Samsung SDI’s leading lithium-ion technology. This MoU with the BMW Group demonstrates the trust in Samsung SDI’s future technology and efficient mass production capabilities. Both companies are confident that this extended partnership will secure their leadership in future technologies.”
