If you want to talk about the hottest tourist destination at the moment, it must be the Northeast. Whether it is the romantic and magnificent Changbai Mountain, or the ice and snow world of ice and snow art, or the ...... of the Songhua River covered in silver, all of which make the small potatoes in the south linger, and often rush to the hot search, bringing a lot of warmth to the cold land of the Northeast in winter, and bringing more joy to everyone. At the same time, a grand skating marathon challenge is also in full swing on the Songhua River in the Songhua River Ecological Tourism Scenic Area in Baishan City, Jilin Province.
As the first Songhua River Ice Skating Marathon Challenge, the grand occasion of the participation can be described as unprecedented, the whole event with the skating marathon as the main body, set up 10 ice and snow sports events and 10 ice and snow experience activities, attracting nearly 10,000 sports enthusiasts to sign up for the competition, the scene is quite a sense of atmosphere on the Songhua River for the New Year.
As the supporting brand of this event, BYD not only actively assisted in the competition, but also brought a variety of models such as Formula Leopard Leopard 5, Denza D9, N7 and Song L to the event site, which not only brought more highlights to the event, but also brought a safer, more stable and more comfortable driving experience in the ice and snow, which also reflects BYD's determination and perseverance to continue to promote and practice the concept of "cooling the earth 1".
Why BYD can bring such a stable and comfortable driving experience on the icy ice and snow land of Northeast China has to mention BYD's years of technology accumulation.
Taking the Leopard 5 as an example, it is equipped with its first DMO off-road dedicated hybrid architecture composed of its first off-road dedicated longitudinal engine, longitudinal EHS electric hybrid system, and CTC battery chassis integration, which brings a strong power performance system to the Leopard 5 and realizes reliable safety guarantee from the inside to the outside. Therefore, the Leopard 5 can not only drive smoothly in the ice and snow environment, but also bring the ultimate stable and safe driving experience. In addition, the technologies and functions supported by the DMO off-road dedicated hybrid architecture such as intelligent electric four-wheel drive, wide-temperature heat pump, cooling and heating refrigerator, and front and rear heating also bring passengers a longer battery life and a more comfortable driving experience.
The DENZA N7, which was exhibited at the event, is the world's first model equipped with pulse self-heating technology. Users who use electric vehicles in the north know that due to the extreme cold winter in the north, the charging efficiency is greatly reduced, and the battery life is also greatly reduced. Based on this scenario, BYD has developed a pulse self-heating technology that divides the battery pack into two, reuses the electrical control topology of the electric appliance, realizes the mutual charging and discharging of half-pack 1 and half-pack 2, and uses the heat pump system to absorb the waste heat of the motor electronic control to improve energy utilization. As a result, the full charging time of the vehicle is shortened by 35% in the case of the battery temperature of -20, which is almost increased compared with the normal temperature environment, so that users in the north can also enjoy the fast charging experience in winter.
In addition, another important factor why the above models can ride in ice and snow is thanks to BYD's self-developed ITAC intelligent torque control system. This technical system has changed the way in the past that only the power output can be used to restore the stability of the vehicle's dynamics, and has been upgraded to torque transfer. Through intelligent allocation of drive torque, power distribution and other control methods, the driving stability of the vehicle is maintained, and the comfort and handling of the vehicle are improved.
The fusion of BYD and Songhuajiang Ice Skating Marathon Challenge, I think it's a successful two-way run. Whether it is the colorful Northeast characteristic culture and scenic spots, or the athletes who compete fiercely with superb skills on the ice, or BYD's amazing technical strength and driving performance, they all reflect a kind of Chinese spirit of hard work, self-improvement, perseverance, and accumulation, which allows me to understand the strong and excellent Northeast culture, and also allows me to see the beautiful life brought by scientific and technological progress.
