After its debut at the Shanghai Auto Show in April and the launch of its first model, officially introduced the e-Platform 3.0 to the public.

At Wednesday night's launch, BYD officially unveiled the e-Platform 3.0 solution, as well as the Ocean X concept car based on it.

The platform is the most critical layout for BYD to move from electrification to intelligence, said BYD Chairman and President Wang Chuanfu at the launch event.

The platform's models use BYD's signature blade battery and a module-less design that integrates the battery with the body, enabling a driving range of up to 1,000 kilometers.

It has a standard eight-in-one electric powertrain, with a maximum power of 270kW for the high-performance version and a 0-100 km/h acceleration time of as fast as 2.9 seconds, according to BYD.

The platform uses electric drive boost fast charging technology and support up to 800V high-voltage fast charging for a range of 150km in as little as 5 minutes of charging.

It uses a new domain-controlled electronic and electrical architecture, Wang Chuanfu said, and BYD thus became the first Chinese automotive company to mass-produce domain controllers.

To solve the problem of short electric vehicle range in winter, BYD has built a heat pump system and introduced an integrated module for thermal management.

With these technologies, the vehicle's battery heat can be integrated to maintain good efficiency in the range of -30°C to 60°C, the company said.

The platform features four domain controllers and the vehicle operating system BYD OS under a new electrical and electronic architecture and enables high-level autonomous driving capabilities.

Based on the architecture and BYD OS, electric vehicles can achieve more powerful autonomous driving capabilities with new features updated as quickly as two weeks instead of two months.

BYD announced the e-Platform 3.0 at the Shanghai Auto Show on April 19, and the Dolphin, the first model based on the platform, was officially launched on August 29 with a price of RMB 93,800 ($14,500) - 121,800 yuan after subsidies.

At Wednesday's launch, BYD unveiled Ocean-X, a concept car that will be a prototype for the company's Ocean series sedan, smaller in size than the flagship Han model.

Wang apologized to consumers at the event for the slow delivery of the DM-i model, saying that production capacity is currently climbing and deliveries will be expedited.

BYD released models with DM-i Super Hybrid technology earlier this year, and their high fuel efficiency has attracted a lot of consumer interest. However, the production capacity of these models has not been able to increase quickly, leading to a large number of consumers' dissatisfaction with the long waiting time.

BYD apologized on May 17 for the delayed delivery of the DM-i models, saying the company was actively making arrangements to speed up the production capacity of these models.

BYD's wholesale sales of new energy passenger vehicles in China reached 60,858 units in August, the highest of any brand, according to data released Wednesday by the China Passenger Car Association (CPCA).

's wholesale sales in China for the month were 44,264 units and SAIC-GM-Wuling's 43,783 units, ranking behind BYD, the data showed.
