Every winter, especially in the northern region, electric vehicle users seem to have made a seventy-or-eight discount on endurance, or even halved. At the current level of technology, is it possible to achieve an increase in low temperature endurance?
In this regard, the BYD e platform sacrificed the "three-plate axe". One is to reduce the drive power consumption, including a higher degree of integration of the electric powertrain, low wind resistance design, etc.; the second is the IPB integrated intelligent electric control, which can use the energy recovery system more efficiently; and finally the large killer heat pump air conditioning system, BYD In addition to using heat pump + PTC auxiliary heating for air conditioning heating, BYD also created the world's first heat pump direct cooling direct heat power battery thermal management program, thermal efficiency increased by 20%.
In order to verify the actual performance of this set of technologies, we came to a one-way endurance challenge of more than 250km in Shenyang, Liaoning province in winter, and under the condition of full air conditioning and heating, what kind of performance will this dolphin with a comprehensive endurance of 405km give?
![About 15,000, these 2 four-wheeled electric vehicles, the endurance is not low, but also oil-electric hybrid, good practicality[fig]](data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACwAAAAAAQABAAACAkQBADs=)
