On April 24, at the 2024 VOYAH Spring Technical Communication Conference, VOYAH unveiled a number of core three-electric technologies: the latest generation of the full-stack self-developed Lanhai power system, which reached the industry-leading level in power and energy consumption, announced 5C super fast charging, which can replenish energy for 450km in 10 minutes, and also demonstrated the next-generation AI algorithm intelligent cockpit of VOYAH. It is expected that the new pure electric SUV model will be released this year, and the first MPV model equipped with Huawei's intelligent driving and intelligent cockpit VOYAH Dreamer will also be launched in the first half of next year.
VOYAH has launched the latest generation of full-stack self-developed Lanhai power system, which is a completely forward-looking power system for the new energy era, with three power modes: BEV pure electric, plug-in hybrid and extended range, and is the only power platform in the current market that can provide three modes. It is equipped with the world's most efficient 800V high-efficiency electric drive system, and the working efficiency under the CLTC standard reaches 92.5%, which is 0.5% higher than the industry's 800V electric drive efficiency, which is a leapfrog improvement in pure electric technology.
This improvement is mainly due to the application of the 800V silicon carbide platform, as the only car company in China that can develop a full-stack self-developed silicon carbide platform, VOYAH's electronic control efficiency can reach 99.4%, based on the world's first application of the latest generation of TMOS 160nm "fine trench gate" chip, which can reduce energy transfer loss by 20%, and the first fluid dynamics elliptical needle fin, which can reduce thermal resistance by 10%. In addition, in terms of the efficiency and stability of the motor, VOYAH also adopts a wrap-around waterfall oil-cooled motor system, which increases the heat dissipation area by 15% while reducing the number of components by 50%, and the motor uses the highest precision "aerospace-grade process" shaft teeth in the industry to achieve the best reducer efficiency.
The PHEV system is a plug-in hybrid system based on the pure electric platform developed by VOYAH, which is composed of a large battery with a range of more than 260km, a large front and rear motor four-wheel drive, and an engine with the highest "thermal efficiency of more than 45%" in mass production in the industry, with a comprehensive range of more than 1,200km, leading the hybrid technology into the 3.0 era. Lanhai Power PHEV is an "intelligent multi-mode drive" system with central integrated control, including a "six-in-one series-parallel" structure of urban pure electric, high-speed direct drive, parallel burst, power loss and range extension, external discharge, and energy recovery, which deeply covers all travel scenarios of users and provides the best power experience. Lanhai Power PHEV also pioneered the AI algorithm of the power system, which selects the most energy-saving power output scheme for users through prediction, optimization and control. Equipped with this hybrid system, the VOYAH vehicle can have the longest pure electric range of 260km, the strongest comprehensive power of 420kW and 840Nm, the fuel consumption is as low as 5.36L/100km and the industry-leading cruising speed of the electric loss.
The range extender power is the third-generation ultra-long range extender system, which adopts the "1.5T deep Miller cycle range extender" that has won the top ten hybrid systems, which can provide a cruising capacity of 310km+ and a comprehensive range of 1400km+ to achieve an "ultra-long" cruising range.
In terms of batteries, VOYAH has brought a new generation of amber batteries, which can provide multiple power options of 80kW·h, 110kW·h and 112kW·h. It adopts the industry's highest 212Wh/kg top-level energy density battery pack, with high specific energy cells and four lightweight designs, and has an ultra-long endurance of more than 900km with the blessing of the 800V platform. Not only that, the mileage attenuation of the Amber 2.0 battery is less than 8% per million kilometers, which is 7 times higher than the 20% attenuation of 300,000 kilometers required by the national standard, and has the highest 16-fold hard-core structural protection and thermal safety technology, so as to achieve "no water ingress, no leakage, no fire, no explosion, no thermal diffusion". The Amber 2.0 battery has undergone more than 20 industry-leading tests and more than 1,200 comprehensive experiments, ensuring battery safety with sufficient redundant safety standards, making users' travel safer and more secure.
In addition, VOYAH also released a new generation of intelligent cockpit, equipped with the world's first OLED sliding curved screen, using super retina technology, contrast ratio of 1000000:1, response time of 5ms, can slide between the central control and co-pilot positions, the edge of the curved screen can also be interacted;
It can be seen that as a national team of new energy vehicle manufacturing, VOYAH's deep technical research and development capabilities and industrial manufacturing capabilities also provide the best application scenarios for Huawei's intelligent technology. This complementary cooperation model not only promotes the rapid development of the business of both parties, but also provides strong support for the intelligent transformation of the entire automotive industry.
