Ultium
Ultium is an electric vehicle battery and motor architecture developed by General Motors. It is planned to be deployed for battery electric vehicles from General Motors portfolio brands along with vehicles from Honda and Acura. Overview. Ultium is characterized by a modular layout, and large, pouch-style cells which can be stacked horizontally or vertically, depending on the form factor needs of each vehicle. A common charging and battery management system serves as the basis for each vehicle's electrical architecture, and a common series of motors and inverters known as "Ultium Drive" will be produced for use across  the entire lineup. Ultium is used by GM's BEV3 platform and BT1 platform. Ultium Drive. Ultium vehicles are powered by a family of five interchangeable drive units and three motors, known collectively as "Ultium Drive." Planned units include: The motors can be configured in front-wheel drive, rear-wheel drive and all-wheel drive combinations. Ultium batteries. In-house Ultium battery cells feature Nickel, Cobalt, Manganese Aluminum (NCMA) chemistry, and will be manufactured in a joint-venture with partner LG. At least four production facilities are planned, as of 2021: The Ultium battery is designed to accommodate charging speeds  of up to 350 kW. Ultium features a wireless battery management system or wBMS, the first battery architecture from any automaker to do so. Vehicles using Ultium. Current Planned
