A few days ago, Xiaopeng Automobile conducted an extremely cold test with a lower temperature than the national standard test temperature for Xiaopeng P5 in China Automotive Technology and Research Center (the national standard test requires -18 °C, this experiment -23 °C), and finally Xiaopeng P5 successfully passed the test with a lower temperature, faster start-up and defrosting speed.
Although the national standard test requirement is only -18 °C, Xiaopeng Automobile in order to be closer to the real winter extreme cold with the car, the experiment began to Xiaopeng P5 for up to 8 hours of professional experimental cabin extreme cold "soaking", until the temperature inside and outside the car dropped to -23 °C. After the frosting of professional and technical personnel, the entire body and windshield of Xiaopeng P5 have been covered with frost flowers.
After that, the staff of China Automobile Research Institute officially began the test, first of all, the remote low temperature start test, when the staff pressed the remote start button on the mobile phone, Xiaopeng P5 started successfully in an instant, far faster than the national standard required within 7 seconds to start;
The second is to detect the defrosting speed of the vehicle, after the vehicle starts, Xiaopeng P5 immediately enters the defrosting working state, and after 20 minutes, the front window defrosting reaches 99.8% (80% of the 20-minute defrosting required by the national standard); within 40 minutes, the defrosting has reached 100% (90% of the 40-minute defrosting above the national standard requirement). In the end, Xiaopeng P5 successfully passed these two tests with a number of indicators higher than the requirements of the national standard.
Although the test conditions are more demanding than the national standard, with the unique X-HP intelligent thermal management system of Xiaopeng P5, it can still have excellent performance beyond the national standard. Xiaopeng P5 is the first model equipped with heat pump air conditioning in the same class, which makes Xiaopeng P5 effectively solve the problem of low temperature energy consumption under the premise of ensuring the thermal comfort of the disabled occupant compartment, and the winter endurance is about 15% higher than that of traditional PTC heating.
In addition, the intelligent safety thermal control of Xiaopeng P5 can achieve an ultra-wide temperature range of -30 °C -55 °C, and according to the needs of the power system, the power system can always be in the best working temperature range, ensure the thermal safety of the power system, shorten the charging time, and increase the mileage.
The low temperature defrosting and heating in traditional fuel vehicles are waste heat generated by the engine, so the heating rate is slower. The heating speed of electric vehicles is significantly faster, which can quickly increase the defrosting and heating speed in the car. In addition, Xiaopeng P5 is equipped with anti-fog sensors and independent defrost dampers as standard, and when the humidity in the car is detected to be too large, the front windshield can be defogged by opening the independent defrost damper, effectively preventing the problem of fogging and frost.
Even in extreme cold conditions, the battery pack of the Xiaopeng P5 can still work normally, so as to ensure the normal start of the vehicle. Therefore, compared with the low temperature start difficulty of traditional fuel vehicles in extremely cold conditions, the advantage of Xiaopeng P5 is that it does not need a low temperature hot car, as long as it is normally powered on. With excellent quality, the Xiaopeng P5 test has dispelled some consumers' worries about the use of pure electric models in winter.
