China’s electric vehicles are making great strides to “go out”.
Are the most important parts-power batteries ready? Recently, the second generation AION V Ian Tyrannosaurus Rex, the first global strategic model of GAC Eian, was launched ceremoniously.
This model, which is to be sold all over the world, must also meet the needs of extremely cold and hot areas, as well as different market standards, as well as higher requirements for power batteries.
, who is the battery supplier of such a “global car” that aims at the global market? It is understood that the power battery of the 750km long-lasting version of the Tyrannosaurus Rex is supplied by Funeng Technology, which contributes its star product-Super soft package solution SPS (Super Pouch Solution) (hereinafter referred to as SPS), which uses ternary material system to achieve long-lasting, fast charging and wide application of electric performance.
Eamba Dragon is another mass production supply project of Funeng Technology SPS after Geely Radar Pure Electric four-wheel-drive pickup Horizon, from four-wheel-drive pure electric pickup to new hard high-end SUV, from Lithium Iron Phosphate to Ternary, Funeng Technology SPS reflects the product competitiveness in multi-dimensional market, multi-material route and multi-application scenario.
, 01, Tyrannosaurus Rex “core”, “this is less than 190000, the industry’s only 750km ultra-long range of SUV, cross-provincial travel does not recharge.
” At the listing conference of Eian Tyrannosaurus Rex, Gu Huinan, general manager of GAC, is full of confidence in the continuation of Eian Tyrannosaurus Rex.
Although the energy consumption performance of Ean Tyrannosaurus Rex is very good, which consumes only 12.
8kwh for 100 kilometers, it still needs enough electricity to run to 750km for a long range.
The ternary material system SPS developed by Funeng Technology for Ian Tyrannosaurus Rex uses the high specific energy cell of 275Wh/kg to make the total charge of the battery system reach 90.
215kWh, ensuring that sufficient electricity is provided within a fixed volume and weight range.
In order to increase the power, many battery systems have to increase the thickness, which makes the seats in the second row are not high enough, such as sitting on a “small bench”, and the head is very close to the roof of the car, which makes the passengers feel depressed.
, 
, the super soft package solution SPS of Funeng Technology, but the ultra-high volume utilization of the SPS can hold enough electricity in a small enough volume without affecting the head and foot space of the second row of passengers.
Ian Tyrannosaurus Rex has the highest legroom in the back row up to 1106mm, with a height of nearly 1.
3m, which is comparable to that of medium and large SUV.
In addition to its long range, the Tyrannosaurus Rex equipped with SPS can also be recharged very fast, traveling 370km in 15 minutes.
Moreover, considering that the charging infrastructure in overseas markets is not as advanced as that in China, Ian King Dragon has also pioneered 400V+3C fast charging technology, in which the 400V platform can accommodate more than 99 per cent of the world’s charging piles and charge compatibility of more than 97 per cent.
In order to achieve high-power fast charging, 400V platform must ensure that large current can pass through without overheating.
, 
, to this end, Funeng Technology SPS has made four improvements.
First of all, during the charging process, the lithium ion should be quickly separated from the positive electrode and embedded in the negative graphite.
Funeng Technology uses secondary granulation, multi-layer doping and other processes, so that the lithium ion can be quickly embedded to improve the charging speed.
Secondly, the cell of Funeng Technology SPS adopts laminated technology and supports all-pole ear design, resulting in shorter transmission distance between positive and negative lithium ions, low resistance, high charging efficiency and low calorific value.
, , fourth, the SPS of Funeng Technology adopts a vertical liquid-cooled plate design, which can achieve liquid cooling on both sides of the cell and heat transfer on three sides, thus increasing the cooling effect by 2.
5 times, ensuring that the heat caused by fast charging is quickly taken away.
Thanks to Funeng SPS, Ian Tyrannosaurus Rex has achieved a 3C fast charging experience comparable to 800V on the 400V platform, charging for 5 minutes, 125km, 15minutes and 370km.
“charge for 300 seconds, run freely in the city.
charge for a quarter of an hour, and it’s easy to get out of the province!” Gu Huinan said.
The global car needs a “global core”.
“this car is to be sold in a place as cold as Russia, and it is very hot in the Middle East.
” Gu Huinan said, “We have also done a lot of consideration about the materials of the battery this time.
” This means that the power battery of the Tyrannosaurus Rex needs to be able to charge and discharge efficiently from minus 30 ℃ to 55 ℃-high battery life and ultra-fast charging in all climates from Siberia to the Sahara.
In order to solve the power supply demand of such a wide temperature range, Funeng Technology provides a solution from two aspects: the intrinsic characteristics of the cell and the thermal management of the battery package.
Funeng Technology SPS carried by Tyrannosaurus Rex adopts ternary material system, so it has good low temperature performance and wider working temperature range.
If you want to further improve the charge and discharge performance of the battery, you need to intervene in the thermal management of the battery pack-heating the battery pack when it is cold and cooling when it is hot.
As mentioned earlier, Funeng SPS’s battery thermal management technology can quickly conduct heat and cool down.
In scenarios that require heating, liquid cooling on both sides becomes heating on both sides-the low-temperature, rapid self-heating design of Funeng Technology enables the battery to heat up efficiently.
The experimental data show that in the environment of minus 20 ℃, the capacity of SPS battery system is always maintained at more than 90%, and the charging time is reduced by half.
, Gu Huinan introduced that the Tyrannosaurus Rex meets the high standards around the world.
In addition to meeting the needs of the world, the power battery also needs to work with the whole vehicle to meet the standards around the world, which requires enterprises to be familiar with the technical standards of the major global markets.
This is not difficult for Funeng Technology.
In 2011, Funeng Technology began to supply power battery systems to global luxury electric motorcycle companies.
in 2016, it entered China’s new energy vehicle market and shipped large-scale power battery systems to domestic manufacturers.
in 2017, it partnered with the international top sports car brand Venturi to help FIA Electric Formula Competition.
in 2018, Funeng Technology reached a strategic cooperation with Germany’s Mercedes-Benz.
In addition, Funeng Technology is also one of the first battery companies to build production capacity overseas.
It can be said that the supply of the “global car” of the Ian Tyrannosaurus Rex is originally a “global core”, and only the global “core” can really make the Ian Tyrannosaurus Rex global.
As Gu Huinan said, “it is not as simple as you think to build a real global car.
” From home to abroad, from the ground to the air.
After the mass supply of Ian Tyrannosaurus Rex, Funeng Technology SPS will continue to produce goods for other car companies.
In fact, from home to abroad, from the ground to the air, Funeng Technology has a forward-looking layout.
InternationallyFuneng not only supplies batteries to Mercedes-Benz cars, but also set up a 50 per cent battery joint venture, Siro, with Turkish electric carmaker Togg.
In addition, Funeng also signed a power battery strategic cooperation agreement with Ingar, an Indian new energy company, and established a cooperative relationship with Moli Power, a power exchange operator in Southeast Asia.
In Turkey, Funeng Technology has built local production capacity based on Siro.
Wang Meng, chairman of Funeng Technology, said that for Chinese battery companies, the international market is very large and the opportunities are good, but there are also great risks, one is that technological innovation is fast, and the other is that international trade barriers may become obstacles.
Turkey is a good fulcrum, import can be exported to the European market, retreat can also supply the rest of the world.
, chairman of Funeng Technology, Wang Jie, besides automobiles, the batteries of Funeng Technology are also “in heaven”.
In May, Funeng confirmed at its performance presentation that its power battery had been awarded a fixed-point contract in the field of manned flight, such as the tilt rotor eVTOL of Shanghai-based TCab Tech.
The case was also reported by CCTV that Funeng Technology became the behind-the-scenes hero of the low-altitude economy.
Funeng Technology completed the development of key technologies for eVTOL power batteries as early as 2017.
supplied samples and completed certification to eVTOL customers for the first time in 2020.
delivered the first generation eVTOL power battery products and verified the second generation product system in 2022.
In 2023, electric aircraft equipped with the first generation of aeronautical power batteries of Fuergy Technology were delivered to end customers, the first example of global commercial delivery.
For this emerging market, Funeng Technology has also prepared the next generation of semi-solid battery products with higher energy density, higher charge and discharge rate, longer cycle times and higher safety.
Funeng Technology is actually the “predecessor” of the power battery industry.
It has been 22 years since its establishment and has always been a front-row player in the battery industry.
Throughout the enterprise history of Funeng Technology, with the trend of traffic electrification, the key products of Funeng Technology, from high-end electric motorcycles to electric vehicles, to low-altitude aircraft, the material routes cover sodium ion, lithium iron phosphate, ternary batteries, and semi-solid and solid-state batteries.
The market demand is changing all the time, but Funeng Technology responds with continuous technological innovation and profound market insight.
For example, before the rise of new energy vehicles, Wang decided that long range was the first problem for power batteries, so he began to develop power batteries to support a range of 300 kilometers in 2005.
At the electric car 100th meeting in 2018, Wang Meng proposed that fast charging will become the next demand point for consumers, reducing the charging time to 15 minutes.
At the World Power Battery Conference in 2022, Wang summarized the eight characteristics that the ideal battery should have in the future, and made the corresponding layout in Funeng Technology a long time ago.
, 
, it is precisely in this way that we continue to study the market and invest in research and development, so that Funeng Technology can continue to bring forth the new and lead the industry.
Funeng Technology’s “global core” and Eian Tyrannosaurus Rex “global car” go out together, will open the prelude of Chinese enterprises to establish a global high-end image.
