Now, pure electric vehicles have become the priority product for many consumers when buying a car; the beautiful shape, advanced technology and lower cost of use make pure electric vehicles a high-quality choice for urban commuting.
However, the reported electric vehicle fire incident has made safety the main concern of consumers for pure electric vehicle models, of which battery safety is the most prominent.
As a tool that needs to shoulder the heavy responsibility of daily travel, the battery pack of electric vehicles needs to face many challenges. From the hot summer heat, to the cold winter temperature test, and even the wading challenges and non-paved pits and stones after the rainstorm, is the battery pack of the domestic pure electric vehicle model safe enough?
In response to the concern of the majority of netizens about the safety of new energy vehicles, the professor decided to pay real money to buy a latest pure electric vehicle, and with a series of cruel violent tests, to verify the safety performance of pure electric vehicles in China today!
The protagonist who will participate in the safety performance test of this electric vehicle is the newly purchased Baojun KiWi EV.
First of all, as a popular car that was freshly launched in August, Baojun KiWi EV has a very good avant-garde design, and the appearance and interior are full of futuristic feeling, which is very prominent in its class.
A futuristic modern car, the Baojun KiWi EV is very much in line with the image of pure electric model avant-garde, personality and high technology.
Secondly, Baojun KiWi EV also has a wealth of scientific and technological configurations, such as remote control, driving assistance, active safety and other functions are equipped.
The 40kW permanent magnet synchronous motor with a capacity of 31.9kWh of battery pack, more support DC fast charging, for Baojun KiWi EV to bring up to 305km of cruising range and more convenient charging methods, in the technical level more than many of the same level of competitors.
And the price of 69,800 yuan is also very grounded, making it an affordable modern car for many young people.
Combining the above points, Baojun KiWi EV is undoubtedly the most suitable fashion travel product for the younger generation at present.
For such a popular model that is popular among young people, its safety performance is naturally very noteworthy.
In fact, for safety issues, automakers have provided comprehensive protection for battery packs through various ways.
Just like the Baojun KiWi EV, don't look at it as a small model, but it is not ambiguous in terms of safety measures involving battery packs!
First of all, from the design of the body structure, Baojun KiWi EV chose to place the battery pack in the core position in the middle of the body, and used anti-collision components made of ultra-high-strength steel around it.
The battery pack itself also uses a shell made of high-strength aluminum alloy, so that it can obtain excellent physical protection in the face of collisions.
Baojun KiWi EV also optimizes the waterproofing of the entire high-voltage system, so that its overall protection level reaches IP67, and the protection level of the battery pack can reach IP67 or above, which means that even if you drive Baojun KiWi EV through the wading section, you don't have to worry about the danger caused by water leakage in the power system.
At the same time, it is equipped with a smart housekeeper function that will detect the battery status at all times, and can perform operations such as power outage and notification to the owner in time when extreme situations occur, and provide technical support for software such as battery preheating function of winter cars.
In addition, Baojun KiWi EV has also undergone up to 16 rigorous safety tests, including fire, collision, extrusion, drop, vibration, overcharge, salt spray corrosion, etc., which can be called "armed to the teeth".
In order to test the safety performance of Baojun KiWi EV, the professor combined the complex road conditions that daily cars may face, and tailored the following cruel tests for Baojun KiWi EV.
Level 1: Wading
Earlier news about continuous heavy precipitation caused by flooding has been heard from time to time, although the pure electric model is not equipped with a fuel engine, not afraid of engine water ingress and causes flameout damage; but once the battery and circuit system into the water, there may also be short circuit, leakage and other situations; light lead to damage to the power system, heavy lead to fire and combustion, very dangerous.
The depth of this wading reached 1150px, simulating whether the waterproof measures of the high-pressure system can be effective when the Baojun KiWi EV passes through extreme wading sections, avoiding water leakage and short circuits.
Level 2: Frozen
Regarding pure electric models, many people think that they are not suitable for use in the northern region; because low temperatures will lead to a significant decline in battery performance, which will seriously affect vehicle performance. So, can baojun KiWi EV's battery system withstand the effects of low temperatures?
The professor will perform rapid cooling treatment on the battery pack of Baojun KiWi EV, simulate the cold environment of the northern winter, and test the working condition of the battery pack at low temperatures.
Level 3: Sea of Fire
In addition to the low temperature environment, the continuous high temperature will also bring challenges to the safety performance of the battery pack; overheating the battery pack may cause damage, and even many consumers will worry that the continuous high temperature will cause the battery pack to catch fire and burn.
In this case, the professor decided to heat the battery pack of the Baojun KiWi EV in a way that far exceeded the daily ambient temperature, which was not only a challenge to the battery thermal management system, but also a cruel test of the high temperature resistance of the battery pack itself.
Level 4: Rocks
Although most of the urban roads are paved, when road construction or need to go to the suburbs, it is inevitable to encounter potholes and gravel on the road. At this time, if the battery pack is directly bumped by the stone, causing deformation or even penetration, it is likely to cause the battery pack to catch fire.
To this end, the professor decided to let the Baojun KiWi EV pass through a road surface covered with larger volumes and sharp corners of the stone, so that the battery pack can directly face the "attack" of the stone during the driving process, and test the strength of the battery pack shell.
After the conclusion of the above series of cruel test projects, the professor will take baojun KiWi EV to a professional venue for disassembly, to see what impact these cruel tests have on the battery pack and other internal structures of Baojun KiWi EV, so as to more intuitively and comprehensively judge the safety performance of Baojun KiWi EV.
Like other tests in the past, in this battery pack safety test, the professor will continue to invite the majority of netizens to witness it!
Professors will track the test in the special mini program, welcome everyone to pay attention to the KiWi EV battery limit breakthrough, let us look forward to the performance of Baojun KiWi EV in the four rounds of challenge levels!
