Avita Kunlun range extension technology officially released

On August 21st, the "reaching the peak" Avita range-extended technology conference was held at the Shanghai Tank Art Center. Avita Technology officially released the range-extended technology - Kunlun Extended Range, entering the range-extended market, and will release a number of pure electric and range-extended power models within the year to fully meet the diversified and all-scenario travel needs of users.

Software and hardware synergy, smart range extension

Hu Chengtai, Vice President of Avita Technology, said: "We believe that a good range extension is when the experience is infinitely close to pure electric, and there is no anxiety about mileage. Avita is a pure electric company As a high-end new energy brand, if it wants to extend its range, it must use pure electric experience as the standard. "For this reason, Avita Technology has applied its peak wisdom to range extension technology for the first time through years of full-stack self-research. The collaboration between software and hardware leads to an intergenerational leap in range extension technology from traditional range extension to smart range extension.

In the process of full-stack self-research, Avita Technology focuses on users’ actual car experience, giving Kunlun extended-range industry-leading capabilities in temperature control, torque control, fuel and electricity control, through millimeter-precision control , promoting a transformation in user perception. Not only that, the blessing of intelligent attributes also gives Kunlun Extended Range the ability to sustain OTA upgrades, extending the "frequently used and always new" car experience to the power domain, truly achieving the ultimate power and quietness comparable to pure electric vehicles. , ultimate peace of mind.

Powerful both with and without power

Traditional extended-range vehicles have strong power when the battery power is sufficient, but in the feed state, the power is seriously attenuated, thus affecting the user's performance in high-power requirements scenarios such as high speed and hill climbing. car experience. In order to solve the above pain points, Avita Technology teamed up with CATL to create a 39kWh Shenxing super hybrid battery, which has a peak discharge rate of 9C when fully charged and can maintain a peak discharge of 7.7C even under low battery conditions. magnification. In this way, the Avita 07 extended-range four-wheel drive model only needs 5.8 seconds to accelerate from 100 kilometers to 100 kilometers even in the power-feeding state.

Not only that, Kunlun Extended Range also independently developed a seven-in-one rear electric drive with a peak power of 231kW and a wheel-end torque of 4500 Nm. Based on this, the Avita 07 extended-range four-wheel drive model takes only 1.8 seconds to accelerate from 40-80km/h and 2.7 seconds from 80-120km/h. It has unimaginably strong power in the speed range most commonly used for overtaking.

Kunlun range extension is a generation-leading range extension technology with wisdom as its core. After continuous acceleration of a new energy vehicle, in order to protect the motor from overheating, the system will intervene in advance to limit the power, resulting in power attenuation. Avita links oil-cooling technology at the hardware level and AI large models at the software level to reduce the rotor temperature measurement accuracy from the industry-wide 30°C to 8°C, an increase of nearly 4 times to avoid premature and excessive ineffective intervention. . Based on this, Avita models equipped with Kunlun's range-extending technology will still have no degradation in performance after 25 consecutive accelerations from 100 kilometers, and acceleration will be on call.

Relying on the global energy smart control system, the Avita extended-range model can adjust the torque according to actual road conditions in scenarios such as going up and downhill, so that users do not need to frequently "recharge" or brake during driving, thus reducing the cost of driving. 60% of the frequency of accelerator pedal changes and braking reduces the dizziness caused by the rapid response of the motor torque, truly achieving "driving without tired feet and riding in a car without motion sickness".

Quiet with or without power

The engine of traditional extended-range vehicles will produce noise when feeding power, especially at low speed or idling, which seriously affects the comfort of the occupants in the vehicle. In order to be as quiet as a pure electric vehicle, Avita independently developed the Kunlun extended-range HE 1.5T supercharged special engine, and equipped it with the world's first electronic oil pump technology and active shutdown piston control technology, successfully integrating The sound pressure in the car during idling charging is controlled at 35.7dB, providing users with a zero-perception extended-range start-stop experience.

Different from traditional oil pumps, the electronic oil pump used in this technology can pre-establish oil pressure and provide delay-free lubrication after the engine starts, thereby effectively reducing noise, improving efficiency, and extending the service life of the engine.

Kunlun Extended Range’s unique shutdown piston active control technology allows Avita Extended Range models to accurately position the piston at the position with the lowest starting cylinder pressure, minimum resistance and lowest vibration when the engine is turned off, thereby significantly reducing engine start-up time. vibration and noise.

Empowered by peak intelligence, the Kunlun Extended Range All-Area Energy Smart Control System connects the smart driving domain and the cockpit domain, and intelligently plans the engine's intervention time based on on-board navigation and road conditions. When Kunlun Extended Range determines that the vehicle cannot drive through the congested sections of the preset navigation route with the current power alone, it will start the engine in advance and give priority to using oil when the road is clear, leaving the electricity for congested sections to ensure that the user can travel even when the road is clear. Even in congested roads crawling at low speeds, you can enjoy the same quietness and comfort as a pure electric vehicle.

Not only does it perform well in terms of quietness, the thermal efficiency and fuel-to-electricity conversion rate of the Kunlun extended-range HE 1.5T supercharged special engine also reach industry-leading levels. Since the supercharged special engine does not need to directly drive the vehicle, compared with the traditional engine of the same displacement, its cylinder diameter is smaller, coupled with higher injection pressure and spark plug energy, the thermal efficiency is increased to 44.39%, burning one liter of oil can It generates 3.63 degrees of electricity, significantly reducing fuel consumption.

No worries about using oil or electricity

At present, the energy replenishment efficiency of traditional extended-range vehicles generally lags behind that of pure electric vehicles of the same level. In addition, traditional extended-range vehicles have a shorter pure electric cruising range, so users need to recharge frequently. Poor energy replenishment experience. In order to optimize the user's energy replenishment experience, the Avita extended-range model will be equipped with the 39kWh Shenxing super hybrid battery. The peak charging rate can reach 3C, and the battery can be charged from 30% to 80% in just 15 minutes. At the same time, Kunlun's extended range technology can bring strong power retention capabilities, ensuring that during daily driving, the battery power will never be exhausted after fuel.

While the battery life is stable, the Avita Kunlun Extended Range can also cope with various harsh natural environment tests such as extreme cold and extreme heat. Even at temperatures of -35℃~65℃, the battery can still normal operation. It also supports No. 92 gasoline, so users can reach any place with a gas station.

Use the most rational persistence to create the most romantic experience. This is the starting point of Kunlun’s extended range and Avita’s best yearning. Avita Technology has been working hard for many years to create Avita Kunlun extended-range technology based on pure electric experience, and is committed to providing users with the ultimate performance, ultimate quietness, and ultimate worry-free range-extended luxury experience!
