BYD Sea Lion 07EV launches in China, what changes does the first adopted e-platform 3.0 Evo have?

On May 10th, BYD Sea lion 07EV officially went on sale. With four configuration models launched, its price range is 189,800 - 239,800 RMB. It can delivery immediately upon listing, and the fastest delivery will be within this month. Sea lion 07EV is the first model built with e platform 3.0 Evo technology and is also the first mid-size pure electric SUV of the ocean network. The new car has many characteristics in both design and platform technology. Combined with price and competition, let's discuss this car below.

I. Understand the Sea lion 07EV car first

In terms of exterior design, the new car also continues the "ocean aesthetic" design concept, such as the X-shaped front face, double U floating headlights, "sea and sky" through taillights and so on, with very high recognition.

In terms of details, the hatchback design is a major feature of the Sea lion 07EV, especially the body posture on the side is very dynamic. Compared with traditional SUVs, it should be more appealing to the younger crowd. I wonder how many points you would rate the exterior design of Sea lion 07EV in front of the screen?

In terms of interior design, the Sea lion 07EV continues the family design style of the ocean network model. The central control station uses more fluid curves in many places, plus the simple design, the cabin atmosphere is younger and more vibrant.

In terms of details, the central control uses color and texture contrast to further emphasize the edge lines of different shapes, and even the door panel design has rich details, cleverly echoing the overall interior. In terms of materials, the official statement is that the soft area accounts for more than 80% of the total interior area, like the seats use a wave pattern quilting and double stitching process. In actual experience, some details are well handled, giving a good sense of quality.

In terms of configuration, the Sea lion 07EV is equipped with the advanced version of the intelligent cockpit - DiLink 100, which includes full scene intelligent voice interaction with four sound zone recognition, K-song and other rich functions. In addition, features like front and rear seat ventilation/heating, aromatherapy, 128 color ambient light, panoramic sunroof with sunshade, AR-HUD head up display, Dana audio system, etc., are all included. Of course, some functions are exclusive to high configuration models, specific needs to check the corresponding model version configuration.

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.

In terms of practical experience, whether it is the seating space in the front and rear rows, or the storage space in the car, Sea lion 07EV performs well, especially thanks to the pure electric platform, the rear row space is also spacious enough. In addition, it also has a front compartment space with a decent volume, the volume of the trunk in the standard state is 500 liters, and the entire rear row seats can be folded down to further expand to 1769 liters.

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

II. What changes does the e-platform 3.0 Evo technology have?

In simple terms, the e-platform 3.0 Evo is a further optimization and upgrade of the original e-platform 3.0 in various parts of the technology. There are many technological points in the design, and the following are mainly the key technologies from the three dimensions of security, efficiency, and intelligence, for everyone to quickly understand.

Safety: All-new Generation CTB Whole Vehicle Safety Architecture

This is primarily composed of rear-drive safety power architecture, steering-forward safety transmission architecture, and endoskeleton-style CTB safety architecture.

Rear-drive layout: It can improve frontal collision safety performance, and the X-direction energy absorption area of the front cabin increases by 100mm, which improves safety performance by 60%.

Steering-forward Layout: This enhances the ability to resist deformation during side collisions, and with a shorter, more coherent transmission path, it can improve deformation resistance by 50%.

Endoskeleton-style CTB: The battery is embedded in the body, which enhances the rigidity of the vehicle. The Sea lion 07EV can reach over 40000+Nm/°.

Efficiency: Powertrain and Thermal Management Efficiency

12-in-one powertrain: This has a higher degree of integration, incorporating boost modules, current increase modules, self-heating modules, etc. The system's combined condition efficiency can reach up to 92%.

1200V Silicon Carbide Power Module: This uses a series of new processes, the most notable of which is the industry-leading stacked laser welding, reducing stray inductance by 75%, improving overcurrent capacity by 10%, and achieving an electronic control efficiency of 99.86%.

Motor Technology: This utilizes ultra-thin silicon steel sheets and other technologies to achieve high speed operation of 23000 rpm. The Sea lion 07EV has been tested to achieve a top speed of 230 km/h.

Thermal Management Efficiency: 16-in-one integrated module, reducing the number and length of pipelines, thus reducing system loss and energy consumption.

Dual-loop direct cooling and heating technology: Optimized water routes enhance heat exchange performance, precisely control battery temperature, and reduce energy consumption.

Compound cooling system of electric drive: It integrates static and rotor intelligent partition multi-layer cooling technology and rotor permanent magnet oil cooling technology, improving heat dissipation efficiency by 40%, and waste heat utilization efficiency by 30%.

Intelligence: Fast charging technology

All-domain intelligent fast-charging solution: It includes intelligent boost fast charging, dual-gun super charging, current increase fast charging, end fast charging, and full-scene pulse self-heating technology.

Pulse self-heating: Under high-frequency alternating current, the battery cell heats up quickly, which is suitable for charging, parking, and driving scenarios.

Increase current fast charging: It decouples the charging voltage from the vehicle voltage, and increases the current on the vehicle side to make full use of the power of public DC charging piles.

End fast charging technology: Uses intelligent pulse charging to shorten the charging time of the last ten percent.

iTAC Intelligent Torque Control System: Custom-developed "Terrain Assistance Mode", "Stuck Vehicle Assistant Mode", and "Drift Mode" for four-wheel-drive models.
