After Huawei’s Mate60 Pro flagship mobile phone became popular all over the network, the M7, which was jointly built by Huawei and Cyrus, also ushered in its own "Mate moment" and became another "far ahead" product in Yu Chengdong’s mouth.
One of the core selling points of M7 is "super security". At the press conference, when Yu Chengdong mentioned "five-fold safety structure, safety should be high above", he cued Contemporary Amperex Technology Co., Limited, a battery partner under the stage. Obviously, Yu Chengdong’s confidence comes from Contemporary Amperex Technology Co., Limited to a great extent. Compared with high-level intelligent driving and price, the author is more concerned about how M7 can achieve a far-reaching lead in the century-long problem of battery safety.
Battery safety is "far ahead", Contemporary Amperex Technology Co., Limited’s "handwriting" and Huawei’s "wonderful pen"
How safe the battery pack is depends on whether there are top-notch battery technologies, reasonable battery protection measures and effective thermal runaway solutions.
Based on Contemporary Amperex Technology Co., Limited’s assistance in battery safety technology, the battery pack of the world M7 has passed a number of thermal safety experiments. Just as Yu Chengdong said, "the battery pack, circuit design and safety overheating protection all reach the highest level". In fact, Contemporary Amperex Technology Co., Limited not only helped Huawei develop this extremely safe battery, but also relied on the extreme manufacturing capacity to mass-produce it quickly. This also proves that Yu Chengdong’s "far ahead" and "safety is paramount" are not empty talk.
The test standard is "far ahead" and the safety is "high above"
Yu Chengdong mentioned that the sub-frame is the lowest point of the chassis, which fundamentally reduces the risk of battery scratching. The "high" here is not only as simple as the structural location layout, but also because Huawei and Contemporary Amperex Technology Co., Limited have set "high safety standards" ahead of the industry.
Contemporary Amperex Technology Co., Limited’s battery pack has obtained extremely high mechanical strength through the unique CTP technology reinforced box design. The test results of this battery far exceed the national standard several times.
For example, in the vibration test, the national standard requires to simulate the mechanical vibration test of 300,000 kilometers of the battery wrapped in the whole vehicle for 10 years, and Contemporary Amperex Technology Co., Limited has also met Huawei’s unique high-standard speed bump vibration test requirements on the basis of the national standard; In addition, the test results of key indicators of batteries such as collision test and extrusion test all exceeded the national standard several times, and performed well.
It’s not hard to understand why, in the face of doubts, Yu Chengdong can confidently express that he is "not afraid of any slander", and even threatened to ask the world that the new M7 is far safer than the 500,000-class mainstream luxury car currently on sale.
Technology is far ahead, and Contemporary Amperex Technology Co., Limited is the guarantee of high performance.
In addition to safety, Contemporary Amperex Technology Co., Limited also added a lot of black technology to the 41.89kWh ternary lithium battery in Wenjie M7.
For example, with the help of Contemporary Amperex Technology Co., Limited’s CTP technology, the M7 can fully demonstrate the high performance of pure electric mode. Contemporary Amperex Technology Co., Limited has optimized the structural parts of battery pack. By using the structural parts made of composite materials and the lower box made of aviation aluminum, the energy density of the battery pack has reached 160Wh/kg, which can easily achieve the excellent effect of battery life of up to 230 kilometers.
In addition, Contemporary Amperex Technology Co., Limited achieved extremely high discharge power by optimizing the battery cell design, and reduced transmission loss by optimizing the whole package high-voltage connection and reducing power consumption at the Pack level. Therefore, this battery pack can provide continuous acceleration power of 315kW and maximum torque of 720N·m for the M7, and its zero-hundred-acceleration is as low as 4.8 seconds, and its power performance is comparable to that of a 3.0T displacement twin-turbo luxury fuel vehicle.
Write at the end:
Ten thousand people hold bows and shoot strokes together, all of which are successful.
Whether HI mode or Smart Choice mode, Huawei gives priority to cooperation with Contemporary Amperex Technology Co., Limited. Obviously, behind the M7 fire, Huawei and Contemporary Amperex Technology Co., Limited share the same idea, that is, the ultimate scientific and technological innovation and the unremitting pursuit of "high above" safety.
Recently, brands such as Aouita and Wenjie invited Contemporary Amperex Technology Co., Limited’s "platform" at the press conference. After all, Contemporary Amperex Technology Co., Limited’s market share of power batteries ranked first in the world for six consecutive years. In the future, consumers may really want to know whether they are equipped with Contemporary Amperex Technology Co., Limited’s batteries before purchasing electric vehicles.
