netcom news on september 19, the opening ceremony of the "byd e-platform 3.0 evo and sea lion 07ev technology experience and co-creation camp" was held at byd's changzhou production base. as byd's first model equipped with the e-platform 3.0 evo advanced technology, the sea lion 07ev has made all-round leaps in vehicle efficiency, power performance, and driving quality.

from its launch on may 10 this year to the end of august, the sea lion 07ev has achieved cumulative sales of over 24,000 units despite insufficient production capacity and only three full sales months.

such achievements are inseparable from the world-class intelligent manufacturing technology, advanced processes and quality control system of byd changzhou production base, the birthplace of haisheng 07ev.

the stamping plant of the changzhou production base adopts the industry-leading 7,900-ton fully enclosed high-speed steel-aluminum hybrid flexible production process, achieving high-efficiency, fully automated production and ensuring the high precision and high quality of stamping parts.

the welding factory adopts intelligent automated production lines, combining cold and hot connection processes. it can produce white bodies made of various steel plates, aluminum alloys and other materials, and ensure the welding quality of the white body.

the painting factory adopts highly automated production and achieves 100% robot spraying. the painting uses the latest environmentally friendly water-based paint, body sealing, body cavity wax injection and other advanced technologies to ensure the durability and appearance of the vehicle's paint.

the final assembly plant adopts modular, automated and information-based production processes. the manufacturing information of each vehicle can be traced throughout the entire process, ensuring the quality of the entire vehicle.

the advanced manufacturing technology has laid a solid foundation for the quality of the sea-lion 07ev in all aspects and dimensions, giving the sea-lion 07ev comprehensive and leading high-end quality.

as the first model equipped with the e-platform 3.0 evo technology, the sea lion 07ev has multiple advantages in terms of safety, efficiency, charging, etc. based on the new generation ctb vehicle safety architecture, the sea lion 07ev is equipped with the world's first endoskeleton ctb safety architecture, which improves the regional body strength by 60% compared with the industry, and the anti-deformation ability of the passenger compartment by 50%, improving the safety of the vehicle and the cabin, and setting a higher safety benchmark.

thanks to the continuous technological evolution of the e-platform 3.0 evo, it brings users a new pure electric experience of low energy consumption and high efficiency. equipped with the world's first high-efficiency 12-in-1 intelligent electric drive system, the energy conversion efficiency of the sea lion 07ev is improved, the system's comprehensive working condition efficiency is up to 92%, and the city commuting range is increased by 50km.

in addition, the sea lion 07ev is also equipped with a new generation of intelligent wide temperature range high-efficiency heat pump system as standard, using the world's first 16-in-1 high-efficiency thermal management integrated module, and intelligent dual-circulation battery direct cooling and direct heating technology, which reduces battery thermal management energy consumption by 25%, and uses a dual-circulation four-area compensation design to improve heat exchange performance by 20%, effectively reducing energy consumption. in extreme vehicle use environments of -30℃ to 40℃, the vehicle's low-temperature cruising range increases by 45km, and the normal-temperature cruising range increases by 60km.

in terms of energy replenishment, in order to solve the daily difficulties of users in finding charging piles and slow charging, the sea lion 07ev is the first to be equipped with intelligent up-current fast charging and full-scenario intelligent pulse self-heating technology. on a public dc charging pile that meets the 2015 version of the national charging standard, the charging time from 10 to 80% soc is as fast as 25 minutes. its intelligent terminal fast charging technology has broken the bottleneck of the last 20% slow charging in the industry, shortening the time from 30 minutes to 18 minutes for 80-100% soc.

in the coming october, the sea lion 07ev will push the eye of god advanced intelligent driving ota, covering six core functions of high-speed navigation such as automatic on- and off-ramp, autonomous lane change/overtaking, and active obstacle avoidance, bringing users a new intelligent electric car experience.
