With the continuous development of new energy vehicle technology, now domestic new energy vehicles can be described as a hundred flowers, charging technology has become more and more a problem that users can not ignore, how to make users more convenient to charge is also a key area of BYD's technological innovation and R&D investment, just to allow users to enjoy the charging experience of the jump.
Recently, at the "More than Fast, All-round Evolution" - BYD Full-Scene Efficient Charging Technology Communication Conference held in Guangzhou, BYD fully demonstrated its innovative achievements in the field of new energy vehicle charging technology to the industry, and the five pioneering technologies solved the charging problem and achieved a breakthrough in charging technology from 0 to 1.
User pain point 1: Poor experience of electric vehicles in the early days, low charging efficiency, BYD solution: BYD's world's first 800V high-voltage platform and step-up charging technology.
In the early stage of the popularization of new energy vehicles, in order to break through the technical ceiling of charging speed and charging experience, and create a more extreme electric vehicle experience for users. BYD took the lead in achieving a breakthrough in 2015 with the world's first 800V high-voltage platform for passenger cars, which was installed on models such as the Qin EV (2015 model) and the Tang DM (2015 model). This technology can increase the fast charging power to 60kW, improving the user experience in all aspects. At the same time, through the boost charging technology, BYD solves the problem of incompatibility between high-voltage models and low-voltage pile charging, and realizes the full compatibility of vehicle piles.
User pain point 2: Most fast charging piles are still not charged fast enough BYD solution: BYD is the world's first dual-gun supercharging technology for passenger cars, making public fast charging piles supercharging piles in seconds.
In the face of the pain points of users who do not charge fast enough in most fast charging piles, BYD launched the world's first dual-gun supercharging technology for passenger cars. This technology upgrades public fast charging piles to supercharging piles, providing users with faster charging services. Taking the DENZA N7 as an example, the maximum power of the dual-gun supercharge can reach 230kW, and it only takes 15 minutes to charge 350 kilometers on a public fast charging pile.
User pain point 3: The charging efficiency in the north is greatly reduced in winter BYD solution: BYD is the world's first full-scene intelligent pulse self-heating technology, which can also be charged quickly in the extreme cold in the north.
In the winter in the north In the case of extreme cold, the charging efficiency of new energy vehicles is greatly reduced, and the reduction of battery energy efficiency is a common problem faced by users. Based on this problem, BYD pioneered the world's first full-scene intelligent pulse self-heating technology, and realized fast charging of cold cars at extremely low temperatures for the first time in the industry. It can self-heat when charging, and can intelligently start the self-heating technology in the parking and driving states to ensure the performance of the vehicle at extremely low temperatures.
User pain point 4: High-power charging is a severe test for battery thermal management, BYD's solution: BYD's world's first composite direct cooling technology.
BYD's world's first composite direct cooling technology has carried out a compensating runner design through the design of straight cold plates on both sides of the battery, as well as two sets of independent control systems for refrigerant, which increases the cooling area of the battery by 100% and the heat exchange capacity by more than 85%, escorting the safety of user overcharging.
As one of the drafting units of China's battery vehicle charging standards, BYD has continued to innovate and invest in R&D with 20 years of technical accumulation and deep skills, and built a charging technology system that is more in line with the current national conditions. Paving the way for the future of green mobility.
