The cold winter is a big test for electric vehicles, and many people are also worried about the power loss of the tram when parked at night, the battery life is discounted, and even the battery is unsafe when driving. Based on these problems, the Cadillac IQ Ruige, a luxury pure electric SUV, conducted a devilish test on the luxury pure electric SUV Cadillac IQ Ruige in an extremely cold environment, in order to test the various performance of the vehicle in an extreme environment, and the results are also unexpected, let's take a closer look.
Challenge the ice breaker
The first challenge is the Freezing Challenge, which tests whether the vehicle's performance remains stable in extremely cold environments. After putting the vehicle in the -30 refrigerator for 12 hours, the performance of the vehicle is checked. As a result, the performance of IQ Ruige is eye-catching, the battery pack temperature is -12, the vehicle has no cold start failure, the door can be opened normally, the car machine runs as usual, the battery life is not lost, and the BEV Heat efficient and integrated thermal management system is normal, and there is no problem in all aspects. Sure enough, as a century-old luxury brand, the pure electric model from the IQ luxury rear-wheel drive platform is trustworthy in terms of quality, quality and performance.
Challenge 2: Extreme battery life
The second challenge is the range challenge, which verifies the true range of the thawed vehicle. The challenge vehicle is the vehicle that has been frozen for 12 hours, with a challenge mileage of 409km, three road conditions: snow, highway and national highway, the temperature is -10 to -2, and the air conditioning in the car is automatically maintained at 24. In the end, the IQ Ruige started 522km, the end showed 23km, the consumption was 499km, and the endurance achievement rate was 82%, which was extremely good.
First, the battery adopts an exclusive long-life and high-stability formula to support fast charging throughout the life cycle, and the battery attenuation of 240,000 kilometers is only 5%. Second, the BEV Heat efficient integrated thermal management system has made great contributions, which adopts a dual-source heat pump design to collect excess heat from the battery, motor and electric drive system for cabin heating, improve heat utilization efficiency, improve vehicle endurance, and maximize energy utilization. This is the reason why IQ Ruige has excellent battery life in the cold.
Challenge the three bumps and trials
The third is the bump challenge, which checks whether the battery pack is still safe after a spike in a collision. In the challenge, the impact column was rushed out of the ground, and the impact force was more than 5000N, which was extremely harsh. In the end, IQ Ruige was successfully completed, the bottom of the vehicle and the battery pack were bumped and scratched in many places, but there was no smoke and leakage, and the battery health was 100% tested by the instrument, with perfect results and reliable safety.
IQ Ruige's battery pack shell is reinforced with multiple 1500MPa ultra-high-strength steel beams, the upper cover assembly adopts 1500MPa super strong side protective beams, and the tray assembly adopts 1000MPa bottom protectionThe application of high-strength steel in the whole package accounts for about 61%, and the application of ultra-high-strength steel accounts for 375% to create ultra-high-strength security protection. In addition, the body is also made of high-strength steel, and the bottom is made of PHS hot-stamping steel to protect the battery from damage. In fact, long before, its battery pack has undergone a super national standard safety test, the drop test is 2 times the national standard, the devil's acupuncture test is also beyond the national standard, and the anti-extrusion test is 3 times that of the national standard, that is, it has to withstand 300KN extrusion, about 30 tons of extrusion weight. Daily driving, no need to worry about small bumps, safe and worry-free.
In the severe cold environment, the three challenges of the Cadillac IQ Ruige have been perfectly completed, withstanding freezing, stable battery life, and bearing bumps.
