Aegis Dagger Battery + Thor EM-i Super Hybrid, Geely New Energy has thrown out two "king bombs"

In recent years, the sales of new energy vehicles in China have exceeded expectations. In October this year, the retail sales of narrow passenger cars reached 2.261 million units, of which new energy passenger cars accounted for 1.196 million units, with a penetration rate of 52.9%. The penetration rate exceeded 50% for the fourth consecutive month.

In the new energy vehicle market, hybrid vehicles, especially plug-in hybrid vehicles, are occupying an increasingly important position. According to data from the China Passenger Car Association, in the first nine months of this year, the cumulative sales of pure electric vehicles in China reached 4.122 million, a year-on-year increase of 17.6%. The cumulative sales of plug-in hybrid vehicles reached 3.01 million, a year-on-year increase of 78.5%, four times the growth rate of pure electric vehicles.

BYD is a leader in the plug-in hybrid market, and its DM super hybrid and blade batteries, which are known for their safety, are still at the top of the new energy technology field. However, it is about to face a powerful rival, Geely Auto.

Recently, Geely Auto released its latest generation of self-developed and self-produced "blade-shaped" lithium iron phosphate batteries - the Aegis Short Blade Battery, as well as the new generation of Thor EM super hybrid technology. The advent of these two technologies will make Geely more comfortable in the new energy market.

First, let’s take a look at the Aegis Dagger battery.

Its length is 580mm, which is 40% shorter than the 960mm of the Changdao battery; its thickness is 18.2mm, which is 35% thicker than the 13.5mm of the Changdao battery.

Why do we need to thicken and shorten? Because for lithium iron phosphate batteries, battery safety not only needs to avoid external collisions and extrusions, but also needs to avoid excessive heat generated by internal current. Generally speaking, the longer the battery, the greater the resistance and the more heat it generates. The short-blade battery has a larger cross-section, shorter length, smaller resistance, and less heat generation, which is not only safer, but also effectively extends the battery life.

In addition, the Aegis Short Blade battery also uses a wet double-coated diaphragm and heat-resistant coatings such as alumina, which is safer than the Long Blade battery cell.

According to the official introduction, the battery cell of the Aegis Dagger battery can achieve 8 times the national standard, and can be pierced by 8 steel needles with a diameter of 5mm at the same time and maintain for 1 hour without smoke, fire or explosion. It is also the world's first battery cell that has successfully passed the 5.8mm real bullet penetration test.

In addition to higher safety, the Aegis Dagger battery is short in size and has low internal resistance. In addition, the optimization and upgrade of the material system has also greatly improved the fast charging performance. The average charging rate is 2.45C, and the power can be charged from 10% to 80% in 17 minutes.

In addition, the short size allows the charge conduction between the positive and negative electrodes of the Aegis Short Blade battery to be faster and the discharge performance to be better. Compared with the thicker Long Blade battery, it allows it to dissipate heat more slowly during low-temperature discharge. In addition, it adds low-impedance film-forming additives to the electrolyte, which can reduce the internal resistance of the battery during low-temperature discharge and significantly reduce the resistance of ions and electrons during low-temperature shuttle. Tests show that the discharge capacity retention rate of the Aegis Short Blade battery is higher than that of the Long Blade battery at temperatures of 0℃, -10℃, -20℃, and -30℃. The lower the temperature, the greater the difference.

Let’s take a look at the new generation of Raytheon EM super electric hybrid technology.

It is divided into EM-i with a single-gear design and EM-P with a three-gear design. Among them, EM-P takes into account both energy saving and performance, while EM-i focuses more on extreme energy saving.

The Thor EM-i Super Hybrid is equipped with a 1.5L four-cylinder engine with a maximum power of 82kW and a maximum torque of 136Nm. Its thermal efficiency reaches 46.5%, the highest among mass-produced gasoline engines in the world. In addition, its 11-in-1 hybrid electric drive technology has the advantages of ultra-high integration, lighter weight and more compactness, achieving efficient energy management and excellent power output.

What's more worth mentioning is that Geely Auto has also introduced artificial intelligence technology for the first time in the field of power systems, launching the car-cloud integrated Star AI cloud power system. Based on the powerful computing power of Geely Star Intelligent Computing Center, the system can more accurately combine the environmental information, driving behavior, navigation information, and road condition information perceived by the vehicle, conduct comprehensive analysis and intelligent decision-making, and improve the vehicle's energy management capabilities. Especially in urban commuting scenarios, this system can save up to 15% of fuel consumption.

Officials said that vehicles equipped with the Raytheon EM-i super electric hybrid have a CLTC comprehensive range of over 2,300 kilometers and a fuel consumption of only 2.67 liters per 100 kilometers. In actual tests, its extreme range and fuel consumption performance are even better.

In recent years, Geely Auto has been making continuous efforts in the new energy vehicle market. As of October, the cumulative sales of Geely Auto's new energy products this year have reached 654,500 units, an increase of more than 91% year-on-year. In addition, it surpassed Tesla in August, September and October, firmly securing the second place among domestic new energy vehicle companies. Now, the arrival of the safer and more efficient Aegis Dagger battery and the more energy-efficient new generation Thor EM-i hybrid technology will surely make it explode further. Let's wait and see.
