Frontier | The industry's first test of the new charging national standard shows that the average charging rate of GWMG's XFC ultra-fast charging battery reaches 8.8C.
Currently, the new energy vehicle market is booming, and ultra-fast charging technology is surging ahead. In both the passenger car and commercial vehicle sectors, ultra-fast charging has become the focus of the industry and society.
On May 20th, Govee Technology completed the industry's first public test after the release of the new charging national standard. The test results show that based on the 800A national standard charging pile, its XFC ultra-fast charging battery only takes 3 minutes and 58 seconds to charge from 5% - 63% SOC, 62 seconds faster than the megawatt flash charging time; it can charge 54.54kWh of electricity in 5 minutes (from 5% - 78% SOC), with an average charging rate of 8.8C, surpassing the performance of competitors on non - national standard 1000A charging piles.
By the end of 2024, the new national standard for high - power charging was fully introduced. It clearly stipulates the voltage and current of the charging interface. The upper limit of the current has been increased from 250A to 800A, and the upper limit of the voltage has been raised from 1000V to 1500V. This standard covers the charging pile gun head and the vehicle - mounted charging socket. This regulation comprehensively considers safety, cost, and energy efficiency. It reserves a redundant space for charging safety and is compatible with both old and new national standard interfaces, avoiding a geometric increase in the component upgrade cost due to the increase in current.
In the industry's first public test of the new charging national standard, the mass - produced and mature battery products of Govee Technology achieved a performance leap through software upgrades. For the 2022 AION V Plus model equipped with this battery, after the software upgrade, the continuous average rate in the 0 - 80% SOC range exceeds 8C, and a higher rate can be achieved in the 20% - 70% SOC range.
That is to say, based on the new charging national standard, the performance of Govee Technology's mass - produced ultra - fast charging battery products has been significantly improved after software iteration, still maintaining a certain advantage compared with the industry's leading level.
Test data of Govee Technology
Pei Feng, the president of Govee Technology, believes that ultra - fast charging will become the standard for electric vehicles, just like the upgrade from manual to automatic transmissions. The era of "no ultra - fast charging, no electric vehicles" is accelerating. 800A is a prudent regulation for the current capacity of DC charging interfaces in China at present, which comprehensively considers safety, cost issues, and efficiency improvement.
He said that Govee Technology always takes scenario requirements into important consideration during the product R & D process, and creates excellent hardware performance with high - standard technology. With the upgrade of the new charging national standard, Govee's batteries have demonstrated unique advantages. Only by implementing software updates can the strong performance contained in the hardware be fully released. Aiming to truly achieve "technological equality and share the beauty of technology", Govee Technology is developing more competitive XFC ultra - fast charging battery products, which are about to be mass - produced and launched.
Technically, Govee's XFC ultra - fast charging battery pays less attention to peak power and emphasizes constant and sustainable charging power.
Pei Feng believes that whether the 0 - 80% SOC fast - charging range can achieve high - power ultra - fast charging throughout the process is the core standard for testing ultra - fast charging. Only achieving full - range constant - power ultra - fast charging is true ultra - fast charging. Govee's XFC ultra - fast charging battery has a peak capacity of 16C, but it adopts a full - process constant - current charging strategy, and the average rate in the test is stable at 8.8C. In contrast, some ultra - fast charging batteries adopt a non - constant - current charging strategy. The initial short - term peak current is 1000A, and the charging rate reaches 10C or even higher, and then the C - rate continues to decline. This charging strategy has a high peak upper limit, requiring larger, more expensive, or non - standard charging piles, and the charging sockets on the vehicle are also non - standard, resulting in limited applicability.
While having an ultra - high rate, with advanced material technology and innovative structural design, Govee's XFC ultra - fast charging / ultra - high - speed charging batteries also feature long service life. It is reported that its normal - temperature ultra - fast charging cycle number is as high as 3000 times. During frequent ultra - fast charging, the battery attenuation is small, and it can always maintain stable performance output, ensuring higher reliability for long - term use.
At the test site, Govee Technology also showed that the battery pack with the longest driving mileage in the background of its battery health monitoring platform has exceeded 310,000 kilometers, and it is in good condition with an attenuation degree of less than 5%.
Ultra - fast charging batteries have strict requirements for manufacturing processes in terms of precision and reliability. Govee Technology is accelerating the construction of high - end production capacity. The professional factory for Govee's ultra - fast charging power batteries started construction in May 2022 and was fully put into production in 2024, marking that Govee has become the first enterprise to achieve large - scale mass production of ultra - fast charging / ultra - high - speed charging power batteries.
While adapting to the new charging national standard and accelerating the popularization of ultra - fast charging, Govee Technology has also accumulated rich technologies in hard - core, high - end, and cutting - edge scientific and technological fields such as advanced new materials and next - generation new energy storage devices, achieving a series of innovative breakthroughs.
It is reported that Govee Technology is researching and developing a new - generation solid - state battery technology around the dual systems of high energy density and high rate. Its maximum energy density can reach 450Wh/kg, and the maximum charging rate can reach 6C.
Pei Feng said that currently, Govee Technology has received support from a national - level major project and has become the undertaking unit for the "R & D and industrial production of composite solid - state electrolytes for solid - state batteries". It is expected to achieve a double breakthrough in "ultra - fast charging + high energy density" within 3 - 5 years.
