【December 24, 2021】In order to focus on the real pain points of low temperature start and low temperature defrosting in the user's winter driving, Xiaopeng Automobile simulates the real car use scenario of the user in winter, and in the industry authoritative organization China Automotive Technology and Research Center, Xiaopeng P5 conducted an extreme cold test with a lower temperature than the national standard test (national standard test requirements -18 °C, this experiment -23 °C), with a lower temperature, faster start and defrosting speed, successfully passed the limit test.

Meet the challenge of extreme cold with Pengpai quality
Low temperature start test, the requirements of the national standard is carried out at a temperature of -18 ° C, and this time Xiaopeng Automobile in order to more realistically simulate the extremely cold conditions in winter, the experiment first carried out a professional experimental cabin extreme cold "soaking" for up to 8 hours on xiaopeng P5 until the temperature inside and outside the vehicle dropped to -23 °C.
(Air outlet temperature is -23°C)
(Actual ambient temperature as low as -24.5°C)
After the professional and technical personnel frosted, the entire body and windshield of the Xiaopeng P5 have been covered with frost flowers.

After the preparation, the staff of China Automobile Research Institute officially started 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 instantaneously, faster than the national standard required within 7 seconds to start; followed by the detection of the defrosting speed of the vehicle, after the vehicle started, Xiaopeng P5 immediately entered the working state, within 20 minutes the front window defrosting reached 99.8% (80% of the 20 minutes above the national standard requirement); in 40 minutes it has reached 100% defrosting. (90% of the 40-minute defrost required by the national standard), and the windshield is not blurred and does not affect the driver's vision.
In the end, Xiaopeng P5 successfully passed these two tests with a number of indicators higher than the requirements of the national standard.

Super group of "black technology" to create super cold performance
More stringent test conditions than the national standard, can still have excellent performance beyond the national standard, it can be said that this is due to xiaopeng P5's unique X-HP intelligent thermal management system. This system is the first time in the same level equipped with heat pump air conditioning, in the air conditioning system efficient, energy-saving, comfortable, in the premise of ensuring the thermal comfort of the crew compartment, all-round energy saving, effectively solve the problem of low temperature energy consumption, winter endurance than the traditional PTC heating increased by about 15%; followed by intelligent safety heat control, can achieve -30 °C -55 °C ultra-wide use temperature range, according to the needs of the power system, so that the power system is always in the best working temperature range, to ensure the thermal safety of the power system, shorten the charging time, increase the mileage.

l Xiaopeng P5 full range of models equipped with indirect heat pump system + water heater two heating methods of air conditioning and heat management system.
l In the extremely low temperature (-10 °C below) the use of water heater for air conditioning heating and battery heating, water heater has the advantages of high power output, fast heating response, to ensure the good performance of air conditioning and battery heating in alpine environment. Cooperate with BMS to achieve rapid heating of the battery under extremely low temperature conditions above -30 °C, and improve the battery charging rate under extremely low temperature conditions.
l Under the driving conditions, the waste heat recovery technology of the motor is used to maximize the use of waste heat generated by the electric drive system during the driving process to heat and insulate the battery pack, increase the depth of low temperature discharge of the battery, and improve the discharge power of the battery.
l At an ambient temperature above -10 °C, the use of heat pump system for air conditioning heating, heat pump system has an energy efficiency ratio of more than 1 (COP), by absorbing the heat of the ambient air to the air conditioning heating use, 1Kw electric power can produce more than 1Kw of heat, can greatly reduce the energy consumption of air conditioning.
l Xiaopeng P5 battery in the temperature range of more than -30 °C can work normally, so as to ensure the normal start of the vehicle, basically meet the needs of users in more than 90% of China's cities

What are the advantages of thermal management of the Xiaopeng P5 compared to traditional cars
Low temperature defrosting and heating in the car of fuel vehicles are the use of waste heat generated by the engine, and the heating speed is slow. Electric vehicles heat up faster, which can quickly increase the defrosting and heating up 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.
Finally, the Xiaopeng P5 battery in the temperature range above -30 ° C can work normally to ensure the normal start of the vehicle. Therefore, compared with the low temperature start of traditional fuel vehicles, the advantage of Xiaopeng P5 is that it does not need a low temperature hot car, as long as it is normally powered on, it can be used.
Witness the truth about quality with the most rigorous testing
From the 550-hour seawater shower experiment to the extreme cold challenge, Xiaopeng Automobile is using the extreme test again and again to test the "Pengpai quality", and using strict challenges to show every user the determination of Xiaopeng Automobile to put quality first. In fact, such achievements are also expected:
In August this year, Xiaopeng P7 won the C-NCAP five-star rating with a super high scoring rate of 89.4%, far exceeding the industry average; In the 2021 China New Energy Product Attractiveness Index Study (NEV-APEAL) released by Power this year, Xiaopeng P7 won the first place in the charm index of the medium-sized pure electric market, which is the first model in the industry to obtain this result; in addition, in the 2021 J.D. Power China New Energy Vehicle New Energy Vehicle Quality Research (NEV-IQS), Xiaopeng G3 also won the first place in the quality ranking of new car quality of new energy vehicle compact models. Behind the double material champion is the "intelligent and reliable" quality reputation of Xiaopeng Automobile, and it is also the most authentic embodiment of the quality of Pengpai
(Xiaopeng P7 obtained the highest score certification of C-NCAP, i-VISTA, and J.D.Power)
The sales volume has continuously exceeded 10,000, which is the user's recognition of the quality of Pengpai
Xiaopeng Automobile has delivered more than 10,000 yuan for three consecutive months since September, and in November it won the first place in the sales of new car-making forces, with a cumulative delivery volume of more than 120,000 units in history, and the beautiful results are inseparable from the trust and recognition of many users for the quality of Xiaopeng Automobile. As a firm pioneer and leader on the intelligent automobile track, Xiaopeng Automobile's "Pengpai quality" DNA that has always run through R&D and manufacturing is becoming increasingly prominent, adhering to the quality of intelligent manufacturing as the cornerstone and the quality control system as the guarantee, Xiaopeng Automobile not only leads the way on the "smart" track, but also sets a new benchmark on the road of "quality".
