What does it feel like to celebrate the New Year on the Songhua River? And there are 7,000 people to celebrate the New Year with you, how lively it will be. Recently, the first China Jilin Songhua River Ice Marathon Challenge was held in the Songhua River Ecotourism Scenic Area in Baishan City, Geely Province, in addition to the ice skating marathon, there are 10 ice and snow sports events and 10 ice and snow experience activities to accompany us to celebrate the New Year. What's even more surprising is that the event has been helped by BYD, the world's leading brand of new energy vehicles, BYD Song L, Denza D9, Denza N7 and Equation Leopard Leopard 5 all appeared on the ice, practicing the determination of "cooling the earth by 1°C" in a piece of ice and snow at -15°C.
But if you want to maintain an efficient and stable car in the ice and snow, many people's practice is to change to a set of snow tires, or the speed is to drive a little slower, and the air conditioner is a little lower, however, these models of BYD can not only drive stably and comfortably on the ice, but also realize the ice and snow environment to use the car and electricity worry-free. So, how does this work? The simple answer is: technology. In BYD's product and technology exploration in the past few years, it has always insisted on seeking a cleaner, more efficient, and more secure way to use cars, which has also made us see the superior technologies that can support all scenarios in these products.
We all know that the electricity consumption of new energy vehicles is a hurdle in winter, and the ultra-low temperature environment will not only make the output power consumption surge, but also the battery efficiency of each link will be relatively reduced, especially in this winter, air conditioning heating is an "invisible killer" for vehicle power consumption. In this regard, BYD has almost achieved the coverage of a wide range of high-efficiency heat pump systems in multi-brand and multi-model, and three of the four models that appeared in the skating marathon have completed the coverage of the technical system, which not only allows the on-board air conditioner of DENZA D9, DENZA N7 and BYD Song L to achieve efficient cooling and heating in a wide temperature range environment of -30°C~60°C, but also can use the waste heat of the power system to heat the air conditioner. Optimize the comprehensive utilization of vehicle energy and minimize the impact of on-board air conditioning on energy consumption levels.
So what about the DENZA N7 that is not equipped with this wide-temperature high-efficiency heat pump? BYD has prepared a set of world-first technology for the DENZA N7 - pulse self-heating technology, which is the first time that this technology has been installed in a production car. To put it simply, this set of technology that can be used in all scenarios is to divide the battery pack into two, so that the battery half pack can charge and discharge each other, and in the process, the heat pump system is used to absorb the residual temperature released by the motor and electronic control system during operation, and this also allows the DENZA N7 to self-heat in all scenarios and under all working conditions, so that the battery can always be kept in the optimal working temperature range.
It should also be mentioned that this technology also directly brings a major benefit, that is, even if the vehicle is charged at -20°C, its actual energy replenishment efficiency will not suffer strong attenuation like other new energy vehicles. Don't forget, the DENZA N7 also has a high-power dual-gun supercharge, even without a supercharging pile, the vehicle can enjoy the supercharging speed, and the "strong combination" of these two technologies in the charging scenario allows the DENZA N7 to achieve ultra-low temperature car, electricity, and charging without worry.
Write at the end
Using technology to empower the use of electricity in vehicles, BYD provides us with a key answer, letting us know why new energy vehicles can maintain efficient operation at -15°C and achieve worry-free electricity consumption in all scenarios. This time to help the first China Jilin Songhuajiang Ice Skating Marathon Challenge, not only to show us the extreme survivability of BYD's new energy vehicles in extremely low temperatures, but also to implement the "1°C cooling for the earth" and bring the concept of green travel to consumers.
