GAC unveils new greater vitality density LFP battery, 1.5L hydrogen engine


Among the many applied sciences displayed at 2022 GAC Tech day on the GAC R&D Middle was a new-generation LFP battery constructed on microcrystalline know-how (SmLFP). In contrast with the present mass-produced lithium iron phosphate batteries available on the market, the super-energy lithium iron battery has a rise of 13.5% in mass vitality density, 20% in quantity vitality density, about 10% in low temperature capability at -20°C, and a quick cost of greater than 2C.

The lifetime of the battery can attain greater than 1.5 million kilometers (>4000 weeks @ 80%)—successfully fixing the technical drawback of a “balanced efficiency” lithium battery.

Apart from the SmLFP know-how, GAC Group displayed its Mega Waves Hybrid Modular Structure (initially introduced in April) and unveiled its 1.5L hydrogen-fueled engine for the primary time, positioned as a component within the hybrid system.

4 main classes of the modular hybrid structure embrace a cheap single-speed system; a dynamic energy cut up system; a power-saving multi-speed system; and a high-efficiency zero-carbon-hydrogen hybrid system.

The hydrogen engine encompasses a hydrogen consumption of 0.84kg/100km. GAC’s first hydrogen engine utilizing hydrogen direct injection know-how was efficiently ignited in September 2021. The operation verification time exceeds 12,000 hours, and the thermal effectivity is anticipated to achieve 44%.

The hydrogen hybrid system contains the hydrogen inner combustion engine and a GMC electromechanical coupling system.

The GMC electromechanical coupling system affords excessive effectivity, excessive efficiency and excessive integration, and is appropriate with all XEV fashions. This 12 months, GAC Trumpchi will launch a flagship MPV mannequin geared up with high-torque GMC, with a pure electrical cruising vary of greater than 100km and a complete system energy of 270 kW.

GAC Group additionally introduced the Psi Working System, its independently developed industry-first, vehicle-wide, cross-domain and standardized working system based mostly on the X-SOUL Electrical and digital structure . The system successfully enhances the car pc techniques’ software program compatibility by unifying its interface and core parts.

A brand new and improved ADiGO Ecosystem, now expanded to incorporate a sensible cockpit resolution along with driving help applied sciences, was additionally unveiled.
The ADiGO SPACE Clever Cockpit System options an clever voice assistant that responds in lower than 0.6 seconds, and top-notch sound system with up-to-date infotainment content material.

In the meantime, the upgraded ADiGO PILOT Clever Driving System is now geared up with 39 superior sensors and a high-performance computing platform. Relevant not solely to superior driving help applied sciences and clever parking, ADiGO PILOT can be utilized in autonomous robotaxi providers.

GAC additionally revealed the hydrogen-powered MPV idea automotive SPACE.
