Among the technologies displayed at 2022 GAC Tech day at the GAC R&D Center was a new-generation LFP battery built on microcrystalline technology (SmLFP). Compared with the current mass-produced lithium iron phosphate batteries on the market, the super-energy lithium iron battery has an increase of 13.5% in mass energy density, 20% in volume energy density, about 10% in low temperature capacity at -20°C, and a fast charge of more than 2C.
The life of the battery can reach more than 1.5 million kilometers (>4000 weeks @ 80%)—effectively solving the technical problem of a “balanced performance” lithium battery.
Aside from the SmLFP technology, GAC Group displayed its Mega Waves Hybrid Modular Architecture (originally announced in April) and unveiled its 1.5L hydrogen-fueled engine for the first time, positioned as an element in the hybrid system.
Four major categories of the modular hybrid architecture include an economical single-speed system; a dynamic power split system; a power-saving multi-speed system; and a high-efficiency zero-carbon-hydrogen hybrid system.
The hydrogen engine features a hydrogen consumption of 0.84kg/100km. GAC’s first hydrogen engine using hydrogen direct injection technology was successfully ignited in September 2021. The operation verification time exceeds 12,000 hours, and the thermal efficiency is expected to reach 44%.
The GMC electromechanical coupling system offers high efficiency, high performance and high integration, and is compatible with all XEV models. This year, GAC Trumpchi will launch a flagship MPV model equipped with high-torque GMC, with a pure electric cruising range of more than 100km and a comprehensive system power of 270 kW.
