Extreme challenge, ice-breaking "star" life. A few days ago, the ultra-comfortable and long-range luxury SUV Star Era ET winter calibration test "-30°C 24-hour immersion ice extreme challenge" was successfully completed in Yakeshi, the ice and snow capital of China. Focusing on the three major pain points of users' winter car battery life, electrical safety, and driving safety, Epoch ET comprehensively verifies the reliability and comfort of the vehicle under strict test conditions, bringing users a comfortable and beautiful mobile space, and making every trip as warm as home.
The world's leading strength solves the three major pain points of users in winter
Fearless of extreme cold, comfort and "star" come together. Relying on Chery Group's 26 years of experience in car manufacturing and tens of millions of users around the world, and in-depth analysis of users' high-frequency scenarios and extreme working conditions, Epoch ET took "the car is an extension of home" as its original intention at the beginning of the design, and used the design concept of home to create an in-car space and create an ultra-comfortable travel experience for users. Epoch ET can also have a sense of security at home even in the face of -30°C extreme challenges, giving users the comfort and peace of mind equivalent to home.
Inheriting the genes of rigorous argumentation and rational truth-seeking of "science and engineering men", Epoch ET has created the first "-30°C 24-hour immersion ice extreme challenge" in the history of new energy vehicles and the industry, including the extreme low temperature endurance test, the battery pack ice water immersion test and the vehicle ice test The "triathlon" extreme cold trial is superimposed, just to solve the three major pain points of users' winter cars.
Test 1: Extreme low temperature endurance test solves the anxiety problem of extremely cold car use in winter
The Epoch ET, which has the best energy consumption performance in its class, far outperforms its peers. Speaking with data is the consistent rational and honest style of "science and engineering men". In this test, the Epoch ET 760km long-endurance version passed through different road conditions on national highways, provincial roads and mountain roads, and under the test conditions of the lowest temperature of -30 °C, it simulated the user's daily car use scene and drove a total of 435.9km in 8 hours after the test conditions of the test with the air conditioning set to AUTO mode 23 °C until the motor stopped the power output. According to the calculation of the low-temperature range of 689km under the standard working conditions, the achievement rate of the extreme low-temperature endurance is 63.3%, and the endurance of the extreme low-temperature range is 95.2% according to the calculation of the cruising range of 458km under the dynamic working conditions. According to the public data of the car emperor, the range achievement rate of the million-level model Model X is 74.4%, and the range achievement rate of the Model Y is 69.7%.
Previously, a large number of tests have shown that the low-temperature mileage achievement rate of new energy vehicles in the low-temperature red line -25 °C environment is generally about 40%. Epoch ET far exceeds the average performance of competing products and the industry, which is due to a number of black technologies inherited and innovated by the "Science and Engineering Man": the 800V high-voltage (electrical) platform can easily achieve 400km of efficient energy replenishment in 10 minutes, the more energy-saving dual heat source heat pump air conditioner, the more efficient SiC motor technology, the more intelligent thermal management system and the battery plug-in gun insulation function...... A solid R&D achievement has won the core competitiveness of the lowest power consumption in the same class of 12.7kwh/100km under CLTC working conditions.
It is worth mentioning that in the low-temperature charging test, when the ambient temperature is -25°C, it only takes 22min to charge 30%-80% of the Star Era ET, which is comparable to the summer charging time. Epoch ET not only runs farther, but also charges faster, so that "the car is an extension of home" is implemented, which greatly alleviates users' anxiety about winter travel.
Test 2: Ice water immersion test of battery pack makes electricity use in extreme environments fully reassuring
The ice water immersion test of the battery pack is higher than the test standard of the national standard, and the battery pack is continuously soaked in the ice-water mixture at <0°C for 60min. After 60 minutes of low temperature immersion, the battery pack of Epoch ET has the same appearance as before immersion, air tightness and insulation. Re-installed on the vehicle can still work normally, excellent performance to ensure the user's driving safety under extreme conditions.
Test 3: The whole vehicle ice test ensures driving safety
The difficulty of the vehicle ice test is that the vehicle is sprayed with high pressure in a low-temperature environment of -30 °C, which is the most effective and difficult test item at present, which extremely tests the tightness of the vehicle, the process level of structural parts, the resistance to low-temperature deformation, the reliability of cold and hot alternating and electrical safety. After 24 hours of ice confinement, the Epoch ET successfully broke the ice and started normally, with super reliability allowing users to enjoy driving safety even in extreme environments.
Extreme ice and snow challenges, just to create a super comfortable mobile home
