Geely Says Their SEA Platform Is Better Than Volkswagen’s Platform
It is an even better platform than what Tesla is using right now.
Vehicle platform engineering is one of the biggest way to save production costs in the auto industry. The idea is simple, use one platform for a variety of models.
This means vehicles using the same basic underpinnings can share almost 60 percent to 70 percent common parts with just very different exterior panels and forms. The vehicles might look very different on the outside, but underneath and under the hood they will be very similar allowing for easy after sales and common replacement parts. This will also allow lower production costs and common factory tooling to be used.
Six leading traits of SEA empowering smart electric vehicles of the future
Geely approached Ford in mid-2008 about a possible takeover of Volvo Cars and the deal reached in late March and completed in early August 2010. Geely and Volvo Cars mutually developed the Compact Modular Architecture (CMA) and B-segment Modular Architecture (BMA) to allow them to develop, design and build different types of compact or smaller cars with similar mechanical layouts faster than before – and at a lower cost.
After 4 years, with an investment of more than 18 billion RMB, the SEA laid the foundation for a three layered ecosystem around whole vehicles, automotive systems, and Internet of Vehicles.
It is the world’s most versatile vehicle architecture, able to accommodate a basic A segment vehicle right through to E segment vehicles including sedans, SUVs, MPVs, city cars, sports cars, pickup trucks and other future vehicles.
At the same time, the SEA architecture also offers the most efficient smart electric vehicle solution, revolutionizing the software development cycle for vehicles and shortening development time by more than 50 percent.
The SEA was developed from the ground up to bring users a smarter and more convenient drive experience with continuous innovations in areas of interior space, electric power, smart connectivity, autonomous driving, safety, and performance.
Space: Maximizing interior space utilization with full A through E-class segment coverage.
The SEA can support the development of models with a wheelbase ranging from 1800mm to 3300mm. A vehicle built on the SEA offers larger interior space than competitive models within the same segment. The SEA not only enables the development of vehicles with increased interior space, it also enables brands to better meet the users’ personalized demands by offering greater design freedom.
Electric power: Battery tested to last 200,000 kilometers degradation free and a design life of 2 million kilometers.
The SEA adopts a three-tiered power management system based around the vehicle’s e-motors, battery management system and charging ecology. The battery has been tested to be able to retain its range without degradation for at least 200,000km and have a design life of 2,000,000km under NEDC operating conditions. The 110kWh modular CTP integrated battery eliminates range anxiety with a long battery range of 700km.
The SEA can accommodate e-motors with power outputs of up to 475kW. In addition, it is equipped with an independently developed high-performance two-speed EV transmission with maximum torque of 8000Nm. In terms of charging speed, the SEA supports an ultra-high speed 800-volt charging system, which can recharge 120 kilometers of range in less than 5 minutes.
