Guangzhou Automobile Science and Technology Museum officially opened! See what real skills you have in building a car.

Technology is one of the most mentioned keys of independent automobile brands in recent years. In fact, in these years of rapid development, we are no longer talking about technology discoloration, but talking about Kan Kan!

On March 19, Guangzhou Automobile Science and Technology Museum was officially opened in Nansha, Guangzhou. Its completion highlights GAC's understanding that technology is the primary productive force, and it is also the epitome of Guangzhou Automobile Group's transformation into a technology-based enterprise.

Guangzhou Automobile Science and Technology Museum is located in the southeast of Guangzhou Automobile Toyota near the junction of Shinan Avenue and Jijiashan Road in Nansha District, Guangzhou, with an area of 16000 square meters and a construction area of 7800 square meters. There are six sections in the museum: sorting hall, power technology, new energy technology, intelligent network connection, responsible Guangzhou Automobile and future-oriented six sections.

So, what technologies and R&D achievements are specifically displayed here?

Modular architecture of GPMA GAC global platform

GPMA is the abbreviation of global platform modular architecture of Guangzhou Automobile Group, which is a platform modular architecture developed by Guangzhou Automobile Group for the world's major automobile markets, covering cars, SUVs, MPVs, PHEV, HEV and other models. It made its official debut at Guangzhou Auto Show in 20 19.

Huge wave mixing

Speaking of mixing, in fact, GAC Chuanqi has 13 years of technical accumulation. At present, in addition to GMC dual-motor series-parallel hybrid system, there is also a THS power split hybrid system. Among them, the self-developed giant wave hybrid is a common series-parallel system, which can cover oil-electric hybrid, plug-in hybrid, extended-range hybrid and hydrogen power system.

The second generation electromechanical coupling system of giant wave hybrid GMC 2.0 is basically the same as the hybrid system of series-parallel logic, and the motor layout is the mainstream P 1+P3. Like lemon hybrid DHT, it adopts 2-speed DHT, but the shifting mechanism of GAC Chuanqi is mainly in at form, which gives play to its own "personality".

In terms of thermal efficiency of internal combustion engine, the highest thermal efficiency of hybrid special engine 2.0ATK independently developed by GAC reached 44. 14% in the laboratory, which once again set a new record for the highest thermal efficiency certification of China brand engines.

AEP pure electric platform

Last year, Aeon released a new generation of high-end pure electric platform AEP 3.0. To say what level this platform has reached, the official statement is that it has completely surpassed Tesla in platform technology! The first model under this platform is Hyper SSR, and the acceleration of 1.9 seconds can be described as lightning speed.

AEP 2.0 has its advantages in large space, long battery life and high safety. Today, AEP 3.0 is based on these, and has been comprehensively upgraded in terms of body structure, lightweight, energy consumption and low-temperature endurance, while paying attention to the creation of driving pleasure.

Spirit electronic and electrical architecture platform

This is the latest upgrade of Guangzhou Automobile Group's car cloud integrated centralized computing spirit electronic and electrical architecture, which is the technology of smart cars. Supporting advanced intelligent driving and intelligent cockpit function applications depends on it!

With an open attitude to the architecture, Guangzhou Automobile Group will maintain security and independent development in the underlying operating system and software algorithms. In terms of peripheral hardware and application software, we will keep an open and * * * attitude, thus creating a richer ecology.

Battery technology

At the Science and Technology Museum, Guangzhou Automobile Group also demonstrated its battery research and development achievements. Super two-speed battery technology, the world's highest 880V high-voltage platform, the fastest charging speed can reach 6 times, it can be charged for 5 minutes and has a battery life of 200 kilometers. In other words, isn't the efficiency the same as adding oil?

Microcrystalline super lithium iron battery technology introduces higher capacity second-phase cathode microcrystals, and improves the energy density through a number of original technologies, so that the battery's low temperature, long life and fast charging performance are comprehensively improved. How awesome is it? In official terms, it is to redefine the lithium iron battery.

The magazine battery that everyone is familiar with has been carried on a large number of models under the Guangzhou Automobile Group. It eliminates potential risks by combining cloud big data with deep learning algorithm. In most cases, the spontaneous combustion of the battery is caused by the internal short circuit of the battery, which leads to the temperature rise, and the internal reaction of the battery generates heat, and finally the heat is out of control, and then it spreads to the whole battery pack ... Therefore, to "not catch fire", it is natural to work hard on the battery.

Just because GAC's magazine battery does not mean that it is enough to repair the battery. Nowadays, the industry has changed from battery safety to system safety, so it must be overcome from three aspects: battery, module and system!

Magazine battery is a system technology specially designed to improve the safety of power battery. It is not purely structural optimization, nor is it simply to increase thermal insulation. It is a set of safety technology from the intrinsic safety of batteries to passive safety enhancement, and then to the active prevention and control of software. Combine soft and hard to improve the defense ability as much as possible.

Simply put, the idea of magazine battery is to prevent short circuit of battery core, prevent thermal runaway after short circuit and prevent thermal spread after thermal runaway.

In terms of core technology, there are mainly four aspects: ultra-high heat-resistant stable battery, ultra-high heat-insulated battery safety cabin, rapid cooling system with extremely fast cooling, and fifth-generation battery management system with full-time control.

In Guangzhou Automobile Science and Technology Museum, the development history of GAC, powertrain technology independently developed by GAC, pure electric platform and battery motor technology, Spirit electronic and electrical architecture platform and ADiGO PILOT and ADiGO SPACE technology, digital GAC, green and low-carbon contribution to society, energy ecological strategy, next-generation platform architecture and chip strategy are presented to the public in an orderly manner, showing all-round scientific and technological innovation achievements and future innovation imagination of GAC.

Finally, Guangzhou Automobile Science and Technology Museum will be open to the public free of charge after its opening. If you are interested in automobile technology and new energy technology, you can explore a lot of new knowledge here and feel the rising power of self-made cars at present!
