What is the hottest thing this winter? The southern little potatoes bravely entered Harbin and are definitely on the list. Sanya, surrounded by sunshine and sand, never thought that it would lose to the icy Harbin in the battle of winter tourism, and Harbin is not only promoting local tourism income, but also promoting the development of ice and snow sports and ice and snow industry in the entire three eastern provinces.
As the initiator and practitioner of "cooling the earth 1", and also the absolute advocate of green travel, BYD gave strong support to this event, and a series of BYD's ace models such as Leopard Leopard 5, Denza D9, N7 and Song L have been unveiled, galloping in the extremely cold weather, enjoying themselves, allowing a group of tourists to realize the novel experience of spending the New Year on the Songhua River, and at the same time, it has also allowed friends in the north to see BYD, as the global leader in new energy vehicles. How to overcome the severe challenge of low temperature to new energy vehicles through technological innovation.
Why is it that the further north you go, the lower the penetration rate of new energy vehicles, especially pure electric vehicles? Mainly because the lower the temperature, the greater the impact on the chemical reaction speed inside the battery, the greater the impact on the battery life and battery charging and discharging efficiency, taking the same pure electric car as an example, when you are in the south, the full battery life can have a 600 kilometers, and the fast charging only takes 2 hours, but in the northeast, the battery life may be about 300 kilometers left, and the fast charging time is extended to 4,5 hours. Therefore, this has led to the common phenomenon that new energy models, especially pure electric vehicles, will decline faster the overall car experience the further north they go.
So, isn't there a solution?
Of course, there is, taking BYD as an example, the following technological innovations, each of which directly hits the pain points of using cars in snow scenes:
Intelligent pulse self-heating technology.
This technology is the world's first with the BYD Denza N7. To put it simply, it is a technology that divides the battery pack into two parts, so that the two battery packs operate according to a specific program through their own motors and electronic control technology, so as to realize the technology of charging each other. It doesn't matter if you don't understand it, the simple understanding is that the DENZA N7 equipped with this technology can achieve the three technical advantages of fast charging, long battery life and fast heating in low temperature scenarios, I will list an official measured data, and you will know better that in the extremely cold environment of minus 20, the charging efficiency of DENZA N7 can be increased by more than 25% compared with traditional solutions, so that the experience of new energy vehicles in the low temperature scene in the north has been qualitatively improved.
Wide temperature range and high efficiency heat pump air conditioner.
Currently, both the DENZA D9 and the BYD Song L are equipped with this technology. Another important reason for the serious discount of battery life of new energy vehicles in low temperature environments is that the lower the outside temperature, the heating power of the air conditioner will be forced to increase, and the more power will be consumed in the same time, which will eventually lead to a discount on the mileage of the whole vehicle, so how does BYD solve this problem? How to understand the wide temperature range, that is, it can work normally at a temperature of minus 30 to minus 60, so how efficient is it? Compared with the traditional scheme, BYD pioneered the power battery direct cooling and direct heating technology, through the compressor to mobilize the heat generated by the major systems of the vehicle in a unified manner, without wasting a trace of residual heat, so that the heat can also be refined according to the outside temperature, the heat utilization efficiency is improved, the energy consumption of the vehicle in the low temperature scene is naturally low, and the mileage of the vehicle has been gratifyingly improved.
ITAC Intelligent Torque Control Technology.
In the northern car scene, snow mode is unavoidable, and vehicle skiddling has become the norm. But BYD resolutely said no! The self-developed ITAC intelligent torque control system allows the vehicle to improve its power, body attitude, handling and so on to varying degrees by intelligently deploying the torque between different tires.
DMO-specific hybrid architecture.
I personally think that in this round of ice and snow events, the coolest model is the indulgence of mountains and seas, the formula leopard leopard 5 galloping in the snow, it is hard to imagine, a big guy close to 5 meters, can be so free and easy in the snow, behind the tough, is the DMO off-road dedicated hybrid architecture, intelligent electric four-wheel drive, Yunlin-P and a series of industry high-precision technology blessing, not modest to say, ice and snow, desert jungle, trekking mountains and rivers, only do not want to go to the distance, there is no equation leopard leopard 5 can not reach the distance.
Cooling the earth 1 is definitely not a simple slogan, with continuous scientific and technological innovation, to promote the transformation of the new energy vehicle industry, to meet the needs of different consumers in different scenarios, so as to promote the popularization of low-carbon green travel mode, BYD has been in action!
