Representatives of multinational car companies in Inhouse components look at the public, see Toyota, is very meaningful. At the end of January this year, the public released its latest layout in the parts business. It has been re-integrated according to the electrification development trend, and aims to external supply.

Volkswagen Group Components (VWGC) is the development and production of the Volkswagen Group in January 2019, responsible for engine, casting, gearbox, chassis, plastic and seven product lines. Today, its idea has severe transformation, and the parts business is re-compliant.

The new business unit is divided into engine and castry, gearbox & electrical driving, chassis & battery system (running through joint venture), battery and charging Battery Cells & Charging Infrastructure 5 major sectors.

These businesses have been manufactured in Kassel, Brunswick and Salzgitter, Hanover, Wolfsburg (Wolfsburg).

Brandik Factory manufactures most parts of chassis and battery systems, including shock absorps, sub-frames, front-rear drive shafts, wheel rotation devices, hardware and software, steering systems, brakes, battery systems, etc. The battery system required by the MEB platform will be produced from the factory, while the battery will be produced from the mass and Northvolt Saarzeti Industrial Factory.

The Cassell plant evolved from the Garage production base of the Volkswagen into electric drive system, producing ZSB electric drive and motor. Its stator and rotor it need are from the Salze Industry Plant. The gearbox housing is produced in Poznań, Poznań, is responsible for the Hannover factory.

Under the cooperation of each business unit, the Volkswagen develops four-step strategic research and development: from the first stage of single components to the second phase of the high-pressure integrated system, the third stage of electric power transmission system (hardware + software ), Eventually realize the platform of the fourth stage.

Obviously, the adjustment of the business unit will facilitate the public to standardize, integrated development, and then transition to the entire power assembly, platform. This can be verified from its battery and battery system technology route.

The public now is the standard module route, and the inherent battery cell can be a soft bag, square. It is a standard battery, and at least 80% of the battery cells are standardized, and thereby constitute a battery system.

This is consistent with the route of battery manufacturers such as Ningde Times. The proposal of CTP and CTC battery system scheme has strengthened the meaning of electrical core standardization. They rely on the module, and even directly fuse the battery and the chassis, remove the unnecessary weight and space occupied by the castings, and achieve the increase in results.

Moreover, according to the interpretation of the Chairman of the Ningde Times, CTC technology will not only re-arrange the battery, but also include high-voltage components such as motor, electric control, DC / DC, OBC. Moreover, CTC can also optimize power distribution and reduce energy consumption by intelligent power domain controller.

The public integrates the chassis to the battery system into a business unit, which is convenient for collaborative development of CTC technology. Moreover, the implementation of its third phase and the fourth stage, will be possible based on this.

At present, the public said that compared with E golf, VWGC has a higher than 10% of the components of ID. 3 and other ID series models, reaching 40%. Combined with its business adjustment, it can be seen that it continues to do the value of the high contribution rate to other car enterprises, allocate, and reduce development costs. It is very likely to leave more available funds to add more intelligent configurations with higher intelligence configurations to additional value.
