Geely released a new generation of blade batteries, and shouted "long knives are not the best solution, short knives are the new generation!" From the name, it will make people suspect that Geely's Aegis short knife battery is shouting the "long knife battery" of friendly businessmen. But since Geely didn't mention those three words, MYAUTO will not step on it, and see if the "short knife new generation" is a gimmick or a real name?
Like the long knife battery, the Geely Aegis short knife battery is a lithium iron phosphate battery. Lithium iron phosphate batteries also have a tendency to dominate the rivers and lakes. Judging from public data, in May this year, lithium iron phosphate accounted for 74% of the power batteries installed in China. In the context of the lithium iron phosphate controversy, the Aegis short knife battery is very aware of the trend.
The reason why the Aegis short knife battery is called short knife is because compared to the 960mm cell length of the long knife battery next door, its battery length is shorter, only 580mm. What are the benefits of making the battery shorter? To put it simply, it will be more flexible and more adaptable when arranged in groups, and can be used in different models such as cars, commercial vehicles, SUVs, and MPVs, which can be called the "vast architecture" in the battery field.
According to Geely, the advantages of the Aegis short knife compared with the long knife battery lie in energy density, battery life, fast charging performance, endurance achievement rate and so on. In terms of cell energy density, the Aegis short knife is 192Wh/kg, and the volume utilization rate is increased by more than 50%, compared with the energy density of the long knife battery is 180Wh/kg, the numerical advantage is still obvious.
HOWEVER, MYAUTO IS MORE INTERESTED IN THE SAFETY OF THE AEGIS SHORT KNIFE BATTERY. When the BYD long knife battery came out, it first played a wave of acupuncture tests, and a needle was used at that time. And the Geely Aegis short knife battery directly borrowed the rake of Marshal Tianpeng, directly pierced it with eight 5 mm steel needles, and kept it for an hour. Judging from the results, there is no smoke, no fire, and no explosion, which is quite reassuring. In addition, Geely also showed a number of battery safety test videos, including the Galaxy L7 vehicle underpinning, L6 three-car chain collision, E8 heavy truck pinching, etc., to confirm their safety concept.
Another point is the life of the battery. The Aegis short knife battery can achieve a cycle life of 3500 laps. In other words, the Aegis Short Knife battery can last almost 10 years while it can be charged once a day. This data is still very impressive. By the way, Geely explained that the "short" physical characteristics of the Aegis short knife battery determine that its internal resistance is smaller, and at the same time, there are carbon nanotube materials and additives with lower film-forming impedance, which can comprehensively improve the fast charging performance, with an average fast charging rate of 2.45C, which is better than the 1.61C rate of the long knife battery. Specifically, the 10~80% SOC charging time of the Aegis short knife battery is only 17 minutes and 4 seconds, compared to 26 minutes for the long knife battery.
Seeing this, it is not difficult to see from the data and publicity that Geely is very targeted this time. Judging from the information that has been obtained, Geely does have a certain advantage in this battery battle. As the first Aegis short knife battery, the Galaxy E5 has naturally attracted much attention.
The Geely Galaxy E5 is positioned as a global model, and it will be supplied to overseas markets in the future, so it is also necessary to consider a more complex environment. So Geely also did a 5.8mm real gun penetration test: after the Type 95 5.8mm automatic rifle bullet pierced the battery cell at a speed of 920m/s and caused a wound of more than 60mm in diameter, the mechanical structure was destroyed by explosive damage, but in the end the battery cell did not catch fire and did not explode.
From the perspective of the product itself, the Geely Galaxy E5 will provide two specifications of 49.52kWh and 60.22kWh batteries, which can drive the CLTC range of 440km and 530km, with a pre-sale price of 130,000 to 170,000. Regarding the parameter configuration, the current known information also includes: length, width and height 4615/1901/1670mm, wheelbase 2750mm, Aegis short knife battery, GEA architecture, 160kW motor, 000 6.9s, top speed 180km/h, Galaxy Flyme Auto cockpit system, 7nm Longying No. 1 car machine chip......
Of course, these are still parameters on paper, whether it is a mule or a horse, you still have to try it on the road. And the battle between long knives and short knives has just begun. BYD has long announced that it will release the second-generation blade battery in August. It is said that the energy density of the second-generation blade battery will be increased to 190Wh/kg. So whether Geely Galaxy E5 can become a new benchmark in the industry, or with the strong rise of local brands, MYUATO hopes that they can create a new pattern of local brands on a global scale.
