The Sustainable Experience Architecture (SEA; Chinese: 浩瀚; pinyin: Hàohàn) platform is a modular electric vehicle platform developed by CEVT, a company based in Gothenburg, Sweden within Geely Automobile Holdings group of companies.^[1] The platform is planned to be deployed to Geely Holding portfolio brands along with the Smart joint venture with Mercedes-Benz Group.^[2]

Geely refers the SEA platform as "open-source," meaning the manufacturer is open to supply the platform to other automakers.^[3] Geely Holding has claimed it has entered into preliminary discussions with other manufacturers about potential use of the SEA platform.^[4]

Overview[edit]

The SEA platform is more of an architecture that unifies multiple platforms covering almost all vehicle types. The platform will consist of five different core versions covering a variety of market segments:^[5]

SEA1 (previously PMA1) for E-segment executive cars with wheelbase of 3,000 mm to 3,019 mm
SEA2 (previously PMA2) for D-segment compact executive cars with wheelbase of 2,900 mm
SEA-E (SEA Entry) for C-segment compact cars with wheelbase of 2,750 mm
SEA-S (previously EPA for Electric Premium Architecture) for S sports cars
SEA-C (SEA Commercial) for commercial vehicles between 3.5 and 5.5 tonnes, including trucks, vans, and buses.

Each core platform will further be available in several different variants such as front, rear, and all-wheel drive, as well as single, double, and triple motor configurations.^[6] Performance is expected to be competitive, with support for both 400V and 800V architectures, fast charging, and 0-60 acceleration times as low as three seconds.^[7]

The predecessor of SEA platform is Geely's pure electric vehicle platform PMA. According to Geely's plan for the SEA architecture, the PMA platform was split into two variants in the later phase with the PMA1, now renamed SEA1, used in medium and large vehicles such as the Zeekr 001, and PMA2, now renamed SEA2, used in small and compact vehicles such as Smart #1.^[8]

The first model based on the SEA architecture is the Zeekr 001 (unveiled on 23 September 2019 as the Lynk & Co Zero Concept) and is being launched in 2021.^[9]

SEA OS is the software component of the SEA platform.^[10]^[11]

On 5 September 2021, Geely and Mercedes-Benz Group announced the Smart Concept #1 based on SEA, and due in 2022.^[12]

Jidu Auto, a joint venture between Geely and Baidu, intends to use SEA for a full portfolio of vehicles in different segments, starting in 2022.^[13]
