Five world-first technologies, BYD builds an all-in-one charging system ahead of the curve

In the early days of the development of new energy vehicles, the industry generally faced the dilemma of three no’s: no charging technology, no charging infrastructure, and no charging standards. In order to solve these development problems, BYD took the lead in achieving a breakthrough in charging technology from 0 to 1. It has independently developed AC and DC charging technologies for household and public use at both the vehicle and pile ends, providing a reference for the national standard AC and DC charging standards. It has also become the first batch of units to draft China's electric vehicle charging standards. BYD's five innovative technologies solve charging problems and give China's new energy vehicle charging technology a "root".

Charging has always been the pain point that new energy users are most concerned about, and it is also a key area of ​​BYD's technological innovation and R&D investment, just to allow users to enjoy a leap in charging experience.

User Pain Point 1: Poor experience with early electric vehicles and low charging efficiency

BYD launches world's first 800V high-voltage platform and boost charging technology

In the early days of the popularization of new energy vehicles, in order to break through the technical limits of power, range, charging, etc., and create a more extreme electric vehicle experience for users, it is imperative to make technological breakthroughs in high-voltage electric vehicles. BYD was the first to achieve a breakthrough in 2015, creating the world's first 800V high-voltage platform for passenger cars, which was installed on Qin EV (2015 model), Tang DM (2015 model) and other models. This technology can accelerate to 100 kilometers in as fast as 4 seconds, the pure electric cruising range can reach 450km, and the fast charging power can be increased to 60kW, improving the user experience in all aspects. BYD's 800V high-voltage platform was 2-3 generations ahead of the industry. At that time, all passenger cars on the market were low-voltage, and only BYD was high-voltage. Today, the industry is competing to enter the 800V high-voltage platform track.

Although high-voltage models have greatly increased the charging power of electric vehicles, at that time, 95% of domestic low-voltage piles were below 500V, which were incompatible with charging of high-voltage models, affecting charging efficiency. In order to solve this problem, BYD has pioneered the world's first boost charging technology, which is completely compatible with vehicle piles and fully adapts to all DC charging piles.

User Pain Point 2: Most fast charging stations still don’t charge fast enough

BYD's world's first dual-gun overcharging technology for passenger cars turns public fast charging stations into overcharging stations in seconds

Currently, only 2% of public supercharging stations with a current of more than 300A are used. Fast charging stations are widely used and supercharging stations are extremely scarce. Rather than letting users compete for a very small number of supercharging stations, it is better to make full use of the existing over one million units. Public fast charging pile resources.

To this end, BYD has launched an upcharging solution that is more in line with my country's charging conditions. It is the world's first dual-gun supercharging technology for passenger cars, allowing public fast charging piles to become supercharging piles in seconds, replenishing energy in a short time, and enabling overcharging everywhere. Taking   Denza N7 ( parameters | inquiry ) as an example, the maximum power of dual-gun supercharging can reach 230kW, and it can charge 350 kilometers in 15 minutes at public fast charging piles.

It needs to be fast and sustainable, but also fast and safe. Because upflow technology poses more stringent challenges to battery thermal management, BYD has pioneered the world's first composite direct cooling technology. Through the design of straight cold plates on the upper and lower sides of the battery, and two sets of independent refrigerant control systems, a compensated flow channel design is carried out. The battery The cooling area is increased by 100%, and the heat exchange capacity is increased by more than 85%, ensuring the safety of users when overcharging.

User Pain Point 3: Charging efficiency is greatly reduced in northern winter

BYD's world's first full-scenario intelligent pulse self-heating technology enables fast charging even in the extreme cold in the north

The northern winter is extremely cold and charging efficiency is slow. BYD pioneered full-scenario intelligent pulse self-heating technology, enabling fast charging of cold cars at extremely low temperatures for the first time in the industry.

Under extremely cold conditions of -30°C, taking Denza N7 as an example, the full-scenario intelligent pulse self-heating technology increases the battery heating rate by 230% compared with traditional solutions, and reduces the battery full charge time by 30%. Northern users can also enjoy fast charging in winter. Full experience.

Not only can it self-heat when charging, but it can also intelligently activate self-heating technology during parking and driving to ensure the performance of the entire vehicle at extremely low temperatures.

Build a charging technology system that is more in line with current national conditions and continuously upgrade users’ full-scenario charging experience

With 20 years of technological accumulation and profound foundation, BYD continues to innovate and invest in R&D to build a charging technology system that is more in line with the current national conditions. It is not only fast, but also continuously upgrades users' full-scenario charging experience.
