The weather in heroic times

As a new force in building cars this year, a network celebrity, Tucki P7' s coupe modeling, suspended transparent screen, Xpilot? 3.0? L3 automatic driving assistance, 4.3 seconds to break 100, 706km long battery life ... from the outside to the inside, it has attracted the recognition and favor of many consumers.

Among many advantages and highlights, the world's first 706km battery life has made it stand out from the crowd. As for the waterless official endurance belt of Tucki P7, we were tested in the endurance challenge held in Xiaopeng Ludao on September 25th.

The activity route of this endurance race is around the coastline of Xiamen Island, with Hollis Cafe as the transfer point, along Huandao East Road, Gao Qi Road, Dudong Road, Yanwu Bridge, passing through Music Square, One Country, Two Systems, Xiangshan Yacht Club, Wu Tong Lighthouse and other scenic spots, with a total length of ***20 traffic lights, about 43km.

In this test, Tucki P7 Rear Drive Long Life Intelligent Edition (NEDC? 670km), Xiamen temperature 2 1-30℃, northeast wind direction, the weather turned cloudy; This test completely simulates the real car scene. During driving, according to daily car habits, turn on the air conditioner and open the window.

At 9am, Tucki P7, fully charged, set off from the charging station and officially started the endurance challenge. The overall road conditions of the event were normal, but when driving normally to the sixth lap, traffic jams began to appear in different degrees throughout Xiamen.

At night 19: 30, after the traffic jam was relatively relieved, Tucki P7 began the endurance test of ninth circle. Because of the use of car lights, the night test also increased the power consumption of Tucki P7.

The endurance test lasted from 9 am to 4: 48 am the next day. After nearly 20 hours of uninterrupted testing, the long endurance challenge was successfully completed. With the speed limit below 60 and the rush hour coming ahead of schedule, the challenge was successfully completed with the result of "flying around the island" 14 lap.

Through the test, we can calculate that the actual cruising range of Tucki P7 is almost 604km, which is about 90% of the official cruising range of 670km. Generally speaking, this measured endurance performance still makes me very satisfied. After all, it exceeds the performance of most pure electric vehicles on the market. At present, the measured and official target percentages are around 80%.

The reason why we can achieve such excellent results is inseparable from the improvement of this car by Xpeng Motors.

It is understood that Tucki P7 adopts the square flexible battery of contemporary Amperex Technology Co., Ltd., with limited core, rated energy of 80.9kWh and energy density as high as 170Wh/kg. At the same time, the battery pack is equipped with intelligent thermal management temperature control system, which realizes the ultra-wide temperature range of -30℃~55℃ and meets the worry-free use in the whole climate.

Thanks to the high-performance three-in-one electric drive system, the volume of the whole electric drive system is only 18.6L, and the power density reaches the industry-leading 2.0 kW/kg. Through system optimization and matching, the highest efficiency of the three-in-one system is >: 93%, and the higher efficiency will naturally transform more electricity into longer battery life and stronger performance.

In addition, Tucki P7 further reduces the unsprung weight by optimizing the suspension material and technology, and the inertia impact is smaller when bumping, thus obtaining better ride comfort and dynamic response. The upper and lower control arms, steering knuckle, shock absorber joint and front fork of Tucki P7 front suspension are all made of aluminum alloy, and the weight reduction effect is obvious. The rear suspension swing arm is made of stamped parts, which are superior in strength and weight to common weldments of the same level, and improve endurance performance everywhere in detail deconstruction.

For electric vehicles, drag coefficient is very important for cruising range. Every time the drag coefficient decreases by 0.0 1, the comprehensive cruising range of NEDC will increase by about 8- 10km. P7, on the other hand, through its unique streamline shape of coupe, extends the duck tail shape, semi-hidden wiper, low wind resistance exterior rearview mirror, low wind resistance wheel hub cover, AGS active air intake grille and almost completely flattened low wind resistance chassis, and finally reaches the ultra-low wind resistance coefficient of 0.236Cd.

Conclusion:

The superior endurance of Tucki P7 is an attack of Xpeng Motors on the market under the current trend of intelligent electric vehicles. By strengthening endurance, more users can avoid the anxiety of travel mileage and create a better travel life.
