It all started with a cup of hot tea on the ice surface of the Songhua River.
On January 30, the Jilin Songhua River Ice Skating Marathon Challenge was held in the Songhua River Ecological Tourism Scenic Area of Baishan City. I was honored to be here as a guest. The grand scene and the fierce competition will not be repeated here, during the filming, because I was wearing a ** work card, I was pulled for help: someone has hypothermia.
The patient is a contestant in this event, the competition uniform is relatively thin, the weather is cold, the physical exertion is relatively large, and the body temperature is quickly lost after sweating, resulting in hypothermia. Fortunately, the situation was not too serious, the patient could still walk and talk, but his body was shaking uncontrollably, and I was already wearing a tin foil blanket when I arrived, and it was not life-threatening, but I did need help.
I just have a warm treasure in my pocket, and I don't care if it's useful or not, I put it on first. Not far away, there is a BYD show car to help this event, a Formula Leopard Leopard 5 is discharging to boil water for the induction cooker, I went to ask for a cup of hot tea, the patient is much better after drinking, and the body is no longer trembling.
Without this cup of hot tea, there is not much health risk to the patient, after all, there are many people at the scene, who will lend a hand, and there is an ambulance on standby a few hundred meters away. But this cup of hot tea, on the icy and snowy Songhua River, can indeed make people more comfortable. This is the gap between fuel vehicles and new energy, a cup of hot tea on the Songhua River.
This time, BYD helped Jilin Songhuajiang Ice Skating Marathon Challenge, and a total of 4 cars were unveiled, namely Formula Leopard Leopard 5, Song L, Denza N7, and Denza D9. There is e-platform 3The Song L and Denza N7 with 0 blessings, with the help of ITAC technology, gallop in the ice, which is indeed calm and steady, and the snow drifting is also exciting enough. However, as a leader in new energy vehicles, it has also proved the limitations of pure electric vehicles in extremely cold weather: at least during the more than ten hours of demonstration, the pure electric Denza N7 and Song L did not dare to turn on the air conditioner.
Some industry insiders concluded that, like the climate, the Qinling Huaihe River is a watershed between pure electric vehicles and plug-in hybrid vehicles. However, with the advancement of new energy technology, I think this dividing line should now be able to advance to Shanhaiguan. Under minus 10 degrees Celsius, under non-extreme conditions, pure electric vehicles equipped with heat pump air conditioners can be competent for most work scenarios. However, out of Shanhaiguan, the temperature is often minus twenty or thirty degrees, and the limitations of pure electric vehicles will be magnified exponentially. For example, in this activity on the ice, the hybrid Denza D9 and Equation Leopard Leopard 5 both unscrupulously turned on the air conditioner, and the in-situ power generation can not only use the waste heat of the engine to heat, but also store the excess energy in the battery, without worrying about the emission and carbon deposition of the in-situ hot car. The heating power of this extremely cold weather should be maintained at 3-5kw, which is equivalent to consuming 3 to 5 kWh of electricity in an hour, and the discharge efficiency of the cold weather is reduced, and the battery pack of 100 degrees can not resist the consumption of more than ten hours.
Hybrid vehicles, on the other hand, have no such problems, as they have almost all the advantages of pure electric vehicles, and there is no range anxiety. Especially in the cold winter, the presence of the engine makes up for the last shortcoming of the pure electric car. Not only that, compared with pure oil vehicles, its advantages are also obvious - in addition to the low cost, low noise, low pollution, strong power, fast response speed of pure electric vehicles, it also has unique advantages in winter. For example, the external discharge function of the plug-in hybrid and a cup of hot tea on the Songhua River can not only save lives, but it can indeed make you more comfortable and comfortable. For example, the battery capacity of fuel vehicles is small, and it is easy to not catch fire in winter, while plug-in hybrid vehicles can drive purely electrically, among which BYD's technology is more mature in this regard, replacing the traditional lead-acid battery as a starting battery with a lithium iron battery, and there is no need to replace it in the whole life cycle, and there is no need to worry about losing power and not igniting.
Pure electric vehicles still have limitations, at least the battery life and heating problems under severe cold conditions have not been completely solved, so there is a pure electric but Shanhaiguan said, but plug-in hybrid has no such problem at all, it does not have the so-called limit, if there is, the grave of fuel vehicles. Perhaps one day in the future, battery technology will undergo a qualitative change, and plug-in hybrids, as a transition, will also retire from the stage of history, just like fuel vehicles.
