I don't know if you found it, now there are more and more new energy vehicles on the road, and this trend is becoming more and more obvious. In today's period of iteration of fuel vehicles and new energy vehicles. Compared with the mature technology and stable quality of fuel vehicles, the endless new energy vehicles in the short term will still be questioned by some consumers, and a large part of the doubt is actually from the concern about safety.
As a newly launched model, Artuka naturally has also received a lot of attention.
Some time ago, the National Automobile Quality Inspection and Testing Center (Beijing Shunyi) announced part of the quality inspection process of Atuka, and we also want to take a look at this hardcore joint venture SUV, whether its quality is also "hard" enough.
1. Battery wading test
When it comes to electricity, what are you most afraid of? It must be water! In people's common sense, electrical appliances can not touch the water. However, as an electric vehicle, it is necessary to shield people from the wind and rain, and it is extremely normal to drive on rainy days. Especially in the south, when the rainy season is rainy and the road area is seriously watery, electric vehicle wading is also a matter of concern. So first, let's consider the reliability of the Atuka battery pack wading.
We soaked Atuka's battery pack in one meter of fresh water for thirty minutes to simulate battery reliability in extreme weather.
After taking it out and then sitting for two hours, Atukao's battery pack did not have the short-circuit fire explosion caused by the water immersion that everyone feared.
Atuka's batteries are designed with a double-layer sealed protection and have no water stains inside the battery pack when opened. It shows that the overall battery sealing of Atuka has a very good level of protection, even in the case of vehicle wading, it will still not be affected.
Subsequently, the insulation resistance was used for detection, and the data showed that the insulation resistance value of the Atuka battery pack was 752Ω/V, which was much larger than the standard of 100Ω/V required by the national standard for the insulation resistance of the battery positive electrode and the housing.
2. Battery extrusion experiment
When the vehicle is driving on the road, an unexpected situation occurs, and when the battery is deformed by the impact of external force squeeze, it is very easy to cause the battery to short-circuit thermal runaway, resulting in the risk of explosion. So what will happen to Atuka's battery pack in the face of this round of extrusion test results?
In order to simulate the extrusion deformation of the vehicle by collision, we performed extrusion tests on the X and Y axes of the Artuco battery pack, stopped when the pressure reached 100 KN or the shape variable reached 30%, and maintained the pressure for 10 minutes.
After the X-axis extrusion test is completed, it is left to stand for two hours, and the Y axis of the battery pack is once again squeezed.
Atuka's battery pack is squeezed under the squeeze of 100KN (10 tons), the battery body basically does not undergo any deformation, and only the external buffer part of the battery pack is squeezed and damaged. In particular, there is a power interface in the X-axis direction, which also has no practical impact on safety.
3. Body rigidity test
In addition to the extrusion test of the battery, we also carry out stress tests on the rigidity of the body. As we all know, when the vehicle encounters collision pressure, the intrusion of the body deformation into the driving space will directly cause injury to the personnel. In particular, the lateral impact accident and rollover accident of the vehicle, the casualty rate is actually high. The requirements for body rigidity and buffer zones on the roof and sides will be higher. This time we will conduct a top static pressure test and a side door squeeze test.
First, a 2.8-ton pressure test was carried out on the roof, and with the push of the instrument, Atukao's body was almost untouched. The test instrument results show that the displacement of the extrusion part of the car is only 20.5mm. Through our observation, we also only saw some damage folds in the roof rack.
So we decided to challenge twice as much as the national standard and perform another squeeze experiment on the other side of the body.
The test results are still no significant deformation!
Next, a side door squeeze test was carried out, which was a 5.7-ton squeeze on the main driver's door, which was three times the mass of the body.
This time, the body has been significantly deformed, and the window glass has also cracked! After the final instrument measurement, the displacement of artuco's pressured part is 215.5mm, which does not infringe on the interior space.
As the sales of new energy vehicles continue to rise, volkswagen will pay more and more attention to the safety of new energy vehicles. This time, we will conduct an "examination" of this newly listed GAC-Mitsubishi Artuka through several common safety accident experiments in life. As the representative model of the joint venture electric SUV, Artuco also handed us a satisfactory answer. With its own excellent strength and rich technology configuration, Artuco will certainly be more favored in the automotive consumer market.
