1. DM technology (Dual Mode technology)
DM technology is Dual Mode technology, which is the abbreviation of BYD dual-mode hybrid technology, and is a pioneering plug-in hybrid technology. After more than 10 years of accumulation of experience and continuous upgrading of technology, BYD has created a dual-mode hybrid technology platform with equally excellent dynamic performance and economic performance. BYD launched the new DM3.0 technology platform in 2018, and launched the DM-p & DM-i dual-platform strategy in June 2020. The DM-p platform focuses on power performance while taking into account economy. The DM-i platform is equipped with a new dual-motor power system. Architecture, focusing on economic performance while taking into account dynamic performance. In mid-November 2020, one of the core components of BYD's DM-i super hybrid technology, the Xiaoyun-Hybrid dedicated 1.5L high-efficiency engine was officially unveiled. The 1.5L high-efficiency engine for Xiaoyun-plug-in hybrid is specially designed for the DM-i super hybrid technology. It is developed to achieve ultra-low fuel consumption, with a thermal efficiency of 43.04%, which is the world's highest thermally efficient mass-produced gasoline engine. As of 2020, BYD DM technology has become the plug-in hybrid technology with the largest installed capacity in the global market.
2. Blade battery
In times of change, transformative technology is needed, and technology is increasingly playing a decisive role. Based on environmental governance and supply chain security considerations, BYD launched a highly secure blade battery in March 2020 through continuous integration and innovation based on new energy industry chain technologies. [85] The blade battery adopts lithium iron phosphate technology, which is a new generation of lithium iron phosphate battery newly developed by BYD. It adopts self-developed large cells with a length of more than 0.6 meters. It is flatter and narrower (the long side can be customized and changed, and the maximum stable length of the single unit can reach 2100 mm). It is arranged in an array and inserted into the battery pack like a "blade", so it is called "" Blade Battery". [88] Since the launch of blade batteries in March 2020, the direction of batteries in China has completely changed, and the loading volume of lithium iron phosphate has increased rapidly. [89] In May 2021, the monthly output of lithium iron phosphate batteries surpassed that of ternary lithium batteries for the first time; in July, the monthly loading volume also surpassed that of ternary lithium batteries for the first time. [82] In December, the output of lithium iron phosphate batteries accounted for more than 63% of the total industry output.
3. e-platform
On April 19, 2021, BYD released a new generation of e-platform (e-platform 3.0) at the Shanghai International Auto Show. [112] The electric vehicle built on the e-platform 3.0 can accelerate from zero to 100 in only 2.9 seconds, and the maximum cruising range can exceed 1,000 kilometers. The power consumption per 100 kilometers is 10% lower than that of models of the same level, and the cruising range in winter is increased by at least 10%.
The e-platform launched by BYD has the characteristics of independent innovation, high integration and extraordinary performance, which can reduce the weight of the vehicle, optimize the layout of the vehicle, improve energy efficiency and reliability, and greatly reduce the cost of vehicle manufacturing. , is the world's leading technology, mature, reliable and safe pure electric solution, known as 33111. The first 3 is a highly integrated drive three-in-one; the second 3 is a high-voltage three-in-one; the first 1 is a highly integrated PCB board; the second 1 is a power battery with long battery life and stable performance; The third 1 is a highly integrated and controlled intelligent automatic rotating large screen, equipped with DiLink system, compatible with millions of mobile phone applications, and open to the outside world. To build an e-platform, it is necessary to understand the core technologies of the whole industry chain of new energy vehicles at the same time. The difficulty and the high threshold are beyond imagination. As an advocate and promoter of the automobile electrification revolution, BYD will share all the technologies of the e-platform with the global automobile industry, accelerate the industrialization of electric vehicles, and jointly push the electrification wave to a new height.
4. DiLink intelligent networking system, D++ open ecosystem and DiPilot intelligent driving assistance system
In 2018, BYD launched the world's first open vehicle-mounted intelligent network connection system. The brand is positioned in the Internet industry and adheres to the design concept of high integration with the Internet. It consists of five platforms: Di platform, DiUI, Di cloud, Di ecology and Di open. Open software and hardware platform and ecosystem service system. The world's first (question 6) intelligent rotating screen, 100% compatible with the mobile phone ecosystem, endows the smart cockpit with more rich content. The industry-first (question 7) mobile phone NFC car key, Bluetooth key, and cloud service key form a digital key for all scenarios. Powerful cloud service functions, clairvoyance, and remote high-temperature disinfection and sterilization allow more functions to be implemented on the mobile phone.
BYD D++ Open Ecology: On September 5, 2018, the BYD Global Developers Conference with the theme of "Opening and Creating the Future" was held in Shenzhen. This is the first developer conference in the 132-year history of the automotive industry. At this developer conference, BYD officially released the D++ open ecosystem. Combined with the previously released DiLink intelligent network connection system and the many developers who have joined the D++ ecosystem, it means that the BYD super smart travel ecosystem has been completed. The D++ open ecosystem provides developers with open interfaces, vehicle data and control permissions based on the world's latest automotive intelligent architecture and security policies. BYD's D++ open platform has attracted a large number of manufacturers to cooperate, and an ecosystem around automobile intelligence and autonomous driving has begun to take shape. In terms of autonomous driving, BYD has cooperated with Baidu, 360 and other companies.
DiPilot intelligent driving assistance system: DiPilot is an intelligent driving assistance system built by BYD with the user as the core, which brings together profound insights into the needs of new energy users. DiPilot consists of DiTrainer and DiDAS, where DiDAS includes automatic emergency braking assist system, forward collision warning system, adaptive cruise, single-lane integrated cruise, traffic jam assist, lane departure warning system, lane keeping system, blind spot detection, automatic Parking, panoramic images, remote control driving and other functions are equivalent to standardized advanced driver assistance systems. Among these functions, APA automatic parking is the first to be applied to BYD Han models. The emergence of BYD DiPilot has not only greatly improved the performance of new energy vehicles in terms of safety, intelligence and personalization, but also injected new vitality into the development of the industry.
