Yesterday we brought the news of Geely's latest generation of Aegis short-bladed battery, today we bring you more detailed information about the battery。First of all, according to Geely, the official name in English seems to be just "New Short Blade EV Battery Technology," but Aegis's name is not mentioned.。

Although the most important specification is still 192 Wh / kg energy density, there are now more known elements about the battery, its function and safety。Geely claims that its lithium iron phosphate battery has first-class battery life, charging speed and ultimate safety。

The Geely short blade battery is 580 mm long, about 40% shorter than the traditional long blade battery. While increasing the volume, the internal resistance and heat generation are smaller and the utilization rate is increased by 50%。

The short blade battery in the test has achieved 3,500 charge cycles。Geely claims that this is equivalent to charging 1 million kilometers。More importantly, this has the least impact on battery attenuation, which helps extend the life of the battery and increase the residual value of used electric vehicles。Geely didn't give any details of how the figure was arrived at, but said it would cut carbon emissions by 80,000 tonnes a year.。Perspective 1 million kilometers e For a car, an average of 20,000 kilometers per year is enough for 50 years。Another key proposition of the new short blade battery is its ultra-fast charging and stable low temperature performance。Geely battery charges 10-80% in 17 minutes and 4 seconds, with an average charging rate of 2.45C, about 1 faster than long blade batteries.5 times, the long blade battery takes about 26 minutes, and the average charging rate is 1.61C。Electric vehicles generally experience a decrease in cruising range at low temperatures. The capacity retention rate of long-blade batteries at a temperature of -30 ° C averages 78.96%, while Geely's new battery maintains 90.54% of capacity。This is achieved by using long and fine carbon nanotubes in the battery to help ion transport and additives that improve the permeability of the film。These changes make it easier for lithium ions to move between electrodes, thereby improving fast charging performance。-Advertising-The battery has passed six extreme tests, including seawater corrosion immersion, extremely cold environment, high-frequency bag bottom scratch, 26 tons of overweight rolling, single bag side collision, and fire baking。These are all carried out by the China Automotive Center, and Geely batteries are all passed。The test standard is higher than the national standard requirements, the scratch test requires 3 times, the rolling test can withstand a weight of 26 tons, the cold resistance test can withstand an equivalent temperature of -35 ℃, 5000m altitude for 8 hours, and baking at 1000 ℃ for 130 seconds。Geely's own test, which involved piercing the battery with eight nails at the same time, had no effect after an hour.。Similarly, Geely launched a standard model to the battery without a hot spot fire (5.8mm) Chinese Army Rifle Bullet。This result is possible because the short blade battery uses "high strength, high thermal stability, high heat resistance diaphragm, highly stable diaphragm with safety electrode, so as to achieve higher energy density and safety。The electrode surface also has self-developed self-melting technology, which can prevent short circuits in the event of an accident.。If the battery is subjected to extreme impact and punctured, the aluminum foil layer will fuse into the battery separator to form an insulating layer。Geely said the battery has "a patented grid frame design, energy-absorbing cavity, three-layer sandwich bottom guard, CTB (cell and body) integration, thermal runaway control system, and a number of other safety features.。Geely Short Blade Battery Certified by CATARC The new short blade battery will debut in the Geely Galaxy E5 SUV, which will be launched in early August.。They will be used for 49.52 kWh and 60.22 kWh battery pack, providing 440 km and 530 km CLTC cruising range respectively。Equipped with Galaxy 11-in-1 intelligent electric drive system, E5 100 kilometers power consumption as low as 11.9kWh / 100km。Source: Geely, Fast Tech.
