Stellantis is boosting production of plug-in hybrids but has lagged some competitors in launching battery-electric vehicles in the United States.
Stellantis North America Chief Operating Officer Mark Stewart on Tuesday acknowledged the automaker was behind "when it comes to bringing the BEVs to this marketplace, but not much."
Last year, Stellantis said it planned to pump $35 billion into electric vehicle production and software globally through 2025.
Stellantis has had strong sales of plug-in hybrid vehicles and is launching its Jeep Grand Cherokee plug-in hybrid this month.
The companies in October announced they were forming a joint venture for lithium ion battery production in North America.
Samsung SDI CEO Yoonho Choi said the company has "secured a solid foothold in a rapidly growing North American EV market through the joint venture with Stellantis."
Samsung SDI will be using its technology PRiMX to produce battery cells and modules for North America.
