FRANKFURT/SEOUL -- Volkswagen Group is making changes to its battery-purchasing plan worth about 50 billion euros ($56 billion) over concerns that a supply deal with Samsung might unravel, according to people familiar with the matter.
Samsung initially agreed to deliver batteries for just over 20 gigawatt hours, enough to power 200,000 cars with 100-kilowatt hour packs, before different views on production volume and schedule emerged during detailed negotiations, said the people, who asked not to be identified as the talks are confidential. The impasse cut pledged supplies to less than 5 gigawatt hours, they said.
Access to vast amounts of batteries to power a growing number of electric vehicles has emerged as a new battleground for global automakers amid capacity constraints, supply bottlenecks and limited access to raw materials. Producing batteries safe to use in cars is more complex than the technology used for consumer electronic devices like smartphones.
"VW ultimately needs 300 gigawatt hours of annual battery cell supply and without robust global multi-sourcing contracts this will be impossible," Evercore ISI analyst Arndt Ellinghorst said. "It's one thing talking up electric vehicle volume numbers, building the necessary value chain remains a major challenge."
VW is spending 30 billion euros on the industry's biggest push into electric vehicles with a new range of purely battery-powered cars to challenge electric-car leader Tesla. The automaker's electric ID3 hatchback will start rolling off assembly lines later this year.
"Samsung continues to be our battery cell supplier for Europe," VW said in an emailed statement. Samsung declined to comment.
Tesla, beset by concerns over demand and its ability to make a profit, last month accused its battery supplier, Panasonic, of being the culprit for tepid production rates of the affordable Model 3.
Earlier this month, VW outlined a project to build a domestic battery-cell factory in Germany together with Swedish startup Northvolt for almost 1 billion euros ($1.1 billion) with capacity of 10 gigawatt hours. VW plans to make a final decision later this year.
VW's electric rollout in the next ten years translates into battery demand of more than 300 gigawatt hours in Europe and Asia alone, outstripping current market capacities.
VW has picked LG Chem, Samsung and SK Innovation as battery suppliers for Europe along with Contemporary Amperex Technology for China. It later added SK Innovation as partner for North America as well, starting in 2022.
The huge investments required to ramp up battery-production capacity have stoked intense rivalry, highlighted by a lawsuit LG Chem filed in the U.S. against SK Innovation over allegedly stealing secrets. SK Innovation has denied acting improperly.
