BYD Sea Lion 07EV launches in China, what changes does it introduce with the adoption of the e-platform 3.0 Evo for the first time?

On May 10, the BYD Sea lion 07EV officially hit the market, with 4 configuration models launched, and the price range is 189,800-239,800 RMB. It will be delivered upon listing, and it will be delivered to the user within this month at the earliest. Sea lion 07EV is the first model built with e-platform 3.0 Evo technology, and it is also the first medium-sized pure electric SUV by Sea lion. Whether it's design or platform technology, the new car has quite a few features. Let's talk about this car together with the selling price and competitors.

I. Let's get to know the Sea lion 07EV

First of all, in terms of exterior design, the new car also continues the "Ocean Aesthetics" design concept, such as the X-shaped front face, double U floating lights, "sky-line" through-type taillights, etc., which are highly recognizable.

In terms of details, the fastback-style body design is a major feature of the Sea lion 07EV, especially the side body posture is quite dynamic. Compared with traditional SUVs, it should appeal to younger groups more. How many points would you rate the exterior design of the Sea lion 07EV?

In terms of interior design, the Sea lion 07EV also continues the family design style of the sea lion vehicle, with many parts of the center console adopting more fluid curves. Combined with its minimalist design, the interior atmosphere of the vehicle is younger and more vibrant.

In terms of details, the center console emphasizes the edge lines of different surfaces through contrast of colors and materials. Even the door panel design has rich details, subtly echoing the overall interior. In terms of materials, the official statement is that the soft-quality area occupies more than 80% of the interior area of the car, such as the seats using water wave pattern stitch and double stitch craftsmanship. From a practical experience perspective, some detail treatments are quite in place, giving a good sense of quality.

In terms of configuration, the Sea lion 07EV is equipped with a high-level version of the smart cockpit-DiLink 100, which includes functions such as intelligent voice interaction in a full range of scenarios with four audio zones and K song. In addition, it contains everything such as front and rear seat ventilation/heating, aroma, 128-color atmosphere lights, full view skylight with sunshade curtain, AR-HUD head-up display, Dana audio system, etc.. Of course, some functions are exclusive to high-end models, you need to check the corresponding model version configuration for details.

In terms of body size, the length x width x height of the Sea lion 07EV are 4830x1925×1620mm, and the wheelbase is 2930mm, which is larger than the Tesla Model Y.

From the actual experience, whether it is the sitting space in the front and rear rows, or the interior storage space, the performance of the Sea lion 07EV is not bad. Especially thanks to the pure electric platform, the rear space performance is spacious enough. In addition, it also has a not small front compartment space, the trunk volume in the standard state is 500 liters, all the back seats folded back can be further expanded to 1769 liters.

Sea lion 07EV provides three power configurations, of which the maximum output power of the 550KM standard version motor is 170kW, and the maximum torque is 380Nm. The maximum output power of the 610KM long endurance version and the 610KM intelligent sailing version motor reaches 230kW, and the maximum torque is 380Nm. The maximum total power of the 550KM four-wheel drive intelligent sailing version motor is 390kW, the maximum total torque is 690Nm, and the acceleration time from 0-100km/h is 4.2 seconds.

II. What changes are there in the e-platform 3.0 Evo technology?

e-platform 3.0 Evo, simply understood as the further optimization and upgrading of each part of the original e-platform 3.0. The design technology points are quite a lot, next will list some key technologies mainly from the three dimensions of safety, efficiency, and intelligence tolet  everyone quickly understand.

Safety: A new generation of CTB vehicle safety architecture

Mainly composed of main rear-drive safety power architecture, front steering safety force transmission architecture, and inner skeleton CTB safety architecture.

Rear-drive layout: It can improve the safety performance of front collision, the X-direction of the front compartment absorption area can increased by 100mm, and the safety performance can increased by 60%.

Front steering layout: It can improve side impact deformation resistance, the force transmission path is shorter and more coherent, and deformation resistance can increased by 50%.

Inner skeleton CTB: The battery is embedded in the body, which increases the rigidity of the body, and Sea lion 07EV can reach 40000+Nm/°.

Efficiency: Electric drive assembly and thermal management efficiency

12-in-1 electric drive assembly: Higher integration, boost module, current increase module, self-heating module, etc., higher efficiency, the highest system integrated working condition efficiency up to 92%.

1200V silicon carbide power module: Using a series of new processes, the most prominent being the industry's first layered laser welding, stray inductance reduced by 75%, overcurrent capacity improved by 10%, electronic control efficiency reached 99.86%.

Motor technology: Using ultra-thin silicon steel sheet technology, achieving high speed 23000 revolutions, Sea lion 07EV tested maximum speed 230km/h.

Thermal management efficiency: 16-in-1 integrated module, reducing the number and length of pipelines, and reducing system loss and energy consumption.

Dual circulatory direct cooling and heating technology: Optimize the water circuit, improve heat exchange performance, accurately control battery temperature, reduce energy consumption.

Electric drive composite cooling system: Integrates stationary, rotor intelligent partition multilayer cooling technology and rotor permanent magnet oil cooling technology, improving heat dissipation efficiency by 40%, waste heat utilization efficiency improved by 30%.

Intelligence: Fast charging technology

Global intelligent fast charging solution: Including intelligent boost fast charging, double gun super charging, current increase fast charging, end fast charging and full scene pulse self-heating technology.

Pulse self-heating: The battery quickly heats up under high-frequency alternating current, suitable for charging, parking, and driving scenarios.

Fast charging with current increase: Decoupling the charging voltage from the vehicle voltage, increasing the vehicle-side current, and fully utilizing the power of public DC charging stations.

Terminal fast charging technology: Use intelligent pulse charging to shorten the last ten percent charging time.

iTAC intelligent torque control system: Custom developed super iTAC multi-scene mode for four-wheel drive vehicles: "Terrain Assistance Mode", "Trapped Vehicle Assistant Mode" and "Drift Mode".
