With the rapid expansion of the new energy vehicle market, consumers are increasingly accepting pure electric vehicles, but the reports of pure electric vehicles from time to time have made the safety of pure electric vehicles power batteries and the safety of whole vehicles one of the key points of consumers' attention when buying cars.
According to the "2021 McKinsey Automotive Consumer Insight" report released by consulting company McKinsey, Chinese consumers are increasingly accepting new energy vehicles, but in terms of safety and other dimensions, consumer concerns have increased instead of falling.
Recently, GAC Mitsubishi's first joint venture hard-core pure electric SUV Artuko completely dispelled consumers' concerns through a video. In a number of tests at the National Automobile Quality Inspection and Testing Center (Shunyi, Beijing), Artuko successfully passed the battery immersion, battery squeezing, and body rigidity tests with high standards. Behind GAC Mitsubishi Artucco's successful pass of rigorous tests, what black technologies has GAC Mitsubishi applied? In addition to bringing consumers a sense of security, what are the hard-core strengths of GAC Mitsubishi Artuco?
extruded water soaking battery is safe and sound
In several tests at the Guojia Automobile Quality Inspection and Testing Center (Shunyi, Beijing), GAC Mitsubishi Artuko's power battery pack first undergoes water immersion test, and its power battery pack is soaked in fresh water with a water depth of 1 meter for 30 minutes. After taking out the pool and letting it sit for two hours, disassembly and check whether there is water inlet inside the power battery pack. The reason why
was the first to conduct the water immersion test is because driving in rainy days is one of the common driving scenarios for vehicles, and the power battery pack is in the chassis position of the vehicle. Whether it is driving in rainy days, washing the car, or when the vehicle is parked in deep water in heavy rainy weather, the power battery pack is prone to contact with water. If there are problems with the sealing and insulation of the power battery pack, it will cause short circuits, leakage and other risks, leaving safety hazards for vehicle safety. Therefore, the power battery needs to undergo rigorous water immersion test.
When the staff of Guojia Automobile Quality Inspection and Testing Center (Shunyi, Beijing) completed the disassembly of GAC Mitsubishi Atuke's power battery pack, it was found that no water inlet was found inside the power battery pack. At the same time, in the detection of insulation resistance , the insulation resistance value of Atuko Power's battery pack is 752Ω/V, which is higher than that of the national requirements of the positive electrode of the pool and the shell. GAC Mitsubishi Atuko power battery pack successfully passed the water immersion test.
GAC Mitsubishi Atuko power battery pack can pass the water immersion test mainly due to the sealing design. It is understood that Atuko's power battery pack adopts a double-layer sealing protection design, with a protection safety level of IP67, which can effectively block water and dust from entering the power battery pack and protect the structural stability and insulation of the internal electrical. In addition, GAC Mitsubishi has conducted nearly 100 safety inspections for new cars that are far higher than the national standards.
undergoes water immersion test, and GAC Mitsubishi Artuko's power battery pack is pushed onto the squeezing test bench again. On the extrusion table, Artuko's power battery pack needs to undergo bidirectional extrusion test with a radius of 75mm semi-cylindrical extrusion plate. The extrusion pressure will reach 100KN (10 tons) and will be kept for 10 minutes, and then stand for observation for two hours.
extrusion test simulates the safety of the power battery when a vehicle encounters a violent collision. If the power battery case invades or squeezes the internal battery cell during a collision, a local short circuit will occur, which will cause the power battery pack to get out of control and cause the vehicle to catch fire.
After the intense extrusion test, the main structure of GAC Mitsubishi Atuko power battery pack did not deform, and the fragile power interface also withstood the test of extrusion and did not have an impact on the safety of the power battery pack. Passed the extrusion test smoothly. The application of
aluminum alloy structural parts enables GAC Mitsubishi Atuko power battery pack to withstand 10 tons of extrusion. In addition, the exclusive platform of aluminum alloy pure electric gives GAC Mitsubishi Artuko the characteristics of high safety, lightweight, and high durability.
Aluminum components application body rigidity improvement
In addition to power battery safety, GAC Mitsubishi also attaches special importance to the safety of the whole vehicle. After two rounds of strict tests for power batteries, GAC Mitsubishi Artuko conducted a rigid test for the whole vehicle.
In the top static pressure test, after GAC Mitsubishi Artuko squeezed the top of the 2.8 tons, it only showed slight wrinkles near the roof rack. After being measured by staff of the National Jia Automobile Quality Inspection and Testing Center (Shunyi, Beijing), the displacement of the extrusion position was only 20.5mm, far lower than the 127mm required by the national standard, and will not have an impact on the members in the car. Even in the 5.6-ton top static pressure test, the displacement of Atuko was minimal.
After completing the top static pressure test, GAC Mitsubishi Artuko ushered in the side door squeezing test. After the door passed a 5.7 tons of squeeze pressure, the window at the extrusion position was also broken as a whole. Although the body changes are obvious than the top static pressure test, GAC Mitsubishi Artuko's performance is still remarkable, with the displacement of the squeezed part being 215.5mm, which does not cause any obvious intrusion into the interior space. GAC Mitsubishi Artuko successfully passed the vehicle rigidity test.
top static pressure test and side door squeezing test mainly restore whether the body structure can provide safety guarantees for drivers and passengers when a vehicle encounters a side collision and rolling accident. In traffic accidents, the degree of casualties caused by side collision and rolling accident is relatively high. According to data released by the China Transportation In-depth Research (CIDAS) working group, the injury rate of rolling accidents is 55.6%, and the mortality rate is 10.9%, which is significantly higher than the front and rear-end collisions.
GAC Mitsubishi Artuko successfully passed the top static pressure test and side door squeezing test with a relatively small displacement, showing that it has excellent body rigidity, ensures the living space of internal occupants, and can provide users with all-round protection. The reason why
was successfully passed the test is derived from the exclusive platform of aluminum alloy pure electric used by GAC Mitsubishi Artuko. The platform has a reliable body structure and chassis structure. It is understood that Atuke uses a large number of high-strength materials such as die-cast aluminum, extruded aluminum, stamped aluminum, and thermoformed steel. The body bending stiffness reaches 26744N/mm and torsional stiffness 2849Nm/rad. In addition, the front longitudinal beam of GAC Mitsubishi Atuko adopts an extruded aluminum alloy structure, which increases the crush energy absorption efficiency by 2.5 times. When a frontal collision occurs, the front longitudinal beam can effectively avoid energy transmission to the crew cabin structure.
At the same time, the exclusive platform of aluminum alloy pure electric is for GAC Mitsubishi Artuko to achieve longer-term battery life and more secure. The CLTC model equipped with ternary lithium batteries has a range of 520 kilometers under operating conditions, which can easily cope with daily commuting and long-distance needs.
