Ice and snow is the main "selling point" of Northeast cities, and when Harbin became an "Internet celebrity", the "wealth of the sky" was once again given to Jilin of the three brothers of Heiji and Liao. On the morning of January 30, the first China Jilin Songhua River Ice Skating Marathon Challenge was held in Jingyu County, Baishan City, Jilin Province, with more than 7,000 ice and snow sports enthusiasts participating in the skating marathon, running marathon, snow bike marathon, ice dragon boat, and cross-country skiing at the same time.
This year's Ice Skating Marathon Challenge is the first in China, and the competition puts forward the concept of "Songhua River Skating Natural Golden Track at 42 degrees north latitude" for the first time, promoting the integrated development of "sports +" culture, tourism, food, entertainment, festivals, business and other formats. Adhering to the concept of "mutual progress, green and humanities", the event will simultaneously carry out 10 ice and snow sports events and 10 ice and snow experience activities with the ice and snow marathon as the main body, becoming the main venue of the "2024 National Fitness New Year's Greeting Event" of the General Administration of Sports of the People's Republic of China, and creating a carnival of winter ice and snow events in Songhua River.
As the initiator and practitioner of the "1°C Cooling the Earth" campaign, BYD has been committed to providing people with clean, efficient and environmentally friendly transportation solutions, and actively participated in the ice and snow events to advocate the concept of green travel. In this Ice and Snow Marathon Challenge, BYD showcased its latest new energy vehicles, including Formula Leopard Leopard 5, Denza D9, N7 and Song L. These models demonstrate BYD's leading position in new energy vehicle technology and its firm determination to promote green mobility, reduce carbon emissions, and protect the environment.
Taking the Leopard 5 as an example, as a model born under the DMO off-road dedicated hybrid architecture, the world's first off-road dedicated longitudinal engine, the world's first longitudinal EHS electric hybrid system, the world's first off-road dedicated rear-wheel drive electric assembly and other technologies, the vehicle's dynamic performance is very strong. The comprehensive power can reach 505kW, which is equivalent to the system power of 5.0T displacement fuel vehicles, and the system torque can reach 760N.m, the maximum traction force can reach 32000N, the maximum climbing is 45°, and the acceleration is 4.8s.
New energy vehicles have the advantages of energy saving, emission reduction, environmental protection and other advantages, but the battery mileage attenuation and poor low temperature resistance have also become pain points affecting consumers' car purchases. The winter car scene in Northeast China is regarded as an insurmountable gap by many new energy vehicle brands, and BYD's performance in the skating marathon challenge can be said to be a perfect slap in the face of the fate of "electric vehicles are not but Shanhaiguan". The DENZA N7 is equipped with a pulsed self-heating system. The system reduces the full charge time of the battery pack by 35% at battery temperatures as low as -20°C, and only increases the full charge time by 25 minutes compared to ambient ambient conditions. Moreover, BYD's pulse self-heating technology can also meet the heating needs of charging, parking, and driving scenarios, which is more advanced than other single-scene heating in the industry.
In addition, BYD's exclusively developed iTAC intelligent torque control system is also a weapon for ice and snow. Even if the skating marathon has to face many slippery road conditions, the vehicle can still maintain the stability of the vehicle by appropriately reducing torque or outputting negative torque. The sensor will accurately predict the change trend of the vehicle state, and dynamically adjust it according to the actual situation such as body posture and wheel status to ensure the acceleration, comfort and handling of the vehicle. What is the experience of driving a BYD on the Songhua River? The answer is undoubtedly safe, stable and comfortable. (Source: Blue Science and Technology Network)
