BYD Ocean Network's product Seal pure electric passenger car spy photo exposure, code name EK, is planned to be put into production at the Changzhou base, currently planning annual output of 60,000 vehicles, the benchmark model is Tesla Model 3.
Seal EK is based on BYD e platform 3.0, charging range will reach 700 kilometers, support 800 volts high voltage fast charging technology, equipped with BYD higher energy density of the second generation of upgraded blade battery.
1. Size
BYD Seal EK adopts a six-fold design, the body size is 4770 * 1860 * 1460 mm, 2900 mm of ultra-long wheelbase, from the side point of view looks very slender, which is mainly due to the e platform 3.0 use of the standardization and integration of parts, a more flat blade battery, to the body to bring more space.
This car benchmark Tesla Model 3, its size is 4694 * 1850 * 1443 mm, wheelbase of 2875 mm, in comparison, SEAL EK has a shorter front and rear overhang, larger space, but also allows EK to use the front double wishbone rear five linkage suspension, which is currently most European luxury cars will be equipped, such as Mercedes-Benz e-class, Audi a6, the main role of this is to improve the handling ability of the vehicle, the overall comfort has also been greatly improved.
2. Rear drive + four-wheel drive
The car is available in rear-drive and four-wheel drive versions. The rear drive is the first post-drive version of the e-platform 3.0, relying on the new eight-in-one electric powertrain.
The new car is divided into three gears, the entry-level EK A model motor maximum power of 150kW, the expected 100 km acceleration time of 6.7 seconds; EK B model motor 180 kW, acceleration time of 5.6 seconds, A, B two models are rear-drive; EKEC model is the strongest, dual motor four-wheel drive combination, the comprehensive power of 360kW, 100 km acceleration time of 3.4 seconds.
3, how to improve the battery life
Seal EK can achieve a single motor to achieve a range of 700 kilometers, and his maintenance quality is only 1.85 tons, indicating that the body does not pile up a lot of batteries, mainly thanks to the development logic of e platform 3.0, which is around improving resource efficiency and reducing resource loss, as well as reusing resources.
The power density of the new eight-in-one electric drive can be increased by 20%, relatively speaking, the power consumption of the entire car is lower, and the integration of body parts at the same time can help the car have a lighter body effect, coupled with the continuous improvement of the blade battery, the energy density of the blade battery has reached 150WH/KG, and it is likely to reach 160-180 or even higher in the next few years.
At present, most car companies want to improve the endurance, the simplest and most practical way is to stack the battery, but the negative effect is relatively large, BYD is to use a complete set of programs to optimize him. At present, the gap will not be particularly large, but in another three or five years, there will be a significant gap in the height of technology.
4. Higher level of intelligent assistance system
The Seal EK will be BYD's first car to have a higher level of intelligent assisted driving. In terms of software, the new BYD OS solves a problem of insufficient system performance, with a 25.7% reduction in response time, and is fully coupled in software and hardware, supporting the core capabilities of higher-level autonomous driving assistance development. In terms of hardware, the highly integrated control domain architecture and regional control can shorten the response time between each other, laying the most basic foundation for the leap-forward improvement of computing power.
BYD will be the first mass production car company to have a production solution equipped with the chassis-by-wire technology, and the vehicles that enter the L3 and L4 levels of autonomous driving must use line-controlled dynamic drive and steering. Only with this wire-controlled chassis can it be said that it has the ability to carry out a high degree of fusion based on the perception system of the vision scheme based on lidar-based, millimeter-wave radar and on-board cameras, and feedback signals to the motor, steering and braking systems very quickly, in order to achieve a relatively safe automatic auxiliary driving system.
That is to say, the e-platform 3.0 system can quickly complete the correct guidance transmitted by visual perception in a shorter period of time and in a more complex environment, so as to make the most correct judgment according to the information, how the car should go, whether it is stopped or walked or avoided, which is what the really very high-level automatic driving should do.
Autonomous driving or assisted driving is built on the basis of hardware keeping up to introduce so-called safer solutions. It's like you're on the road right now, you can see some dangers with the naked eye, but your reaction speed can't keep up, that's nonsense, and consumers want results.
E-platform 3.0 is not only about what kind of cars BYD can build in the future, but also has a profound impact on the entire automotive industry. Because the core purpose of e platform 3.0 is to help intelligent car electrification vehicles to achieve a basic solution, this technology BYD will be shared and open to the entire industry across the country and even the world, I believe that in the future we can see more car companies and BYD e platform 3.0 cooperation.
