Upgrades to the Lanhai power 800V platform mean that Voyah claims it has the world’s more efficient 800V electric drive system with an efficiency rate of 92.5% under the CLTC standard. The system has three power modes pure electric, PHEV hybrid and REEV range extension. Voyah says that 800V platform gives vehicles an additional 50 km of range under the same power.

An AI algorithm is used by the Lanhai Power PHEV system to optimize energy efficiency. The PHEV system itself is able to operate in six modes: pure electric, high-speed direct drive, parallel burst, power loss and range extension, external discharge, and energy recovery. The 1.5T Miller cycle engine has thermal efficiency of more than 45% and this is coupled with a large capacity battery capable of giving a range of 260 km (CLTC). Combined with front and rear motors comprehensive power is 420 kW and maximum torque is 840 Nm. Fuel consumption of the system is 5.36 l/100 km. Voyah’s third generation PHEV system can deliver a range of over 1200 km.

Voyah’s latest generation of Amber batteries come in 80, 110 and 112 kWh packs. Energy density is 212 Wh/kg and combined with an 800V platform can deliver ranges of 900 km. Mileage attenuation of the Amber 2.0 is less than 8% per million kilometres which is seven times better than the minimum national standard rate of 20% per 300,000 km. Amber 2.0 batteries also feature structural protection and thermal safety technology to achieve no water ingress, no leakage, no fire, no explosion, no thermal diffusion. They’ve undergone 20 industry-leading test and 1,200 experiments to ensure safety.

Voyah’s self-developed 5C super-fast charging x800V silicon carbide platform can allow the batteries to add 450 km of range in 10 minutes. Furthermore Voyah claims to have developed the world’s first 8C charger. Peak power is 1000 kW and it can add 500 km of range in just five minutes or 1.7 km per second. The charger has a 1000 A current.
