The following are some of the information that Car Cloud has learned.
Volkswagen's goal is to achieve annual sales of 1 million electric vehicles by 2025. To achieve this goal means that Volkswagen's products are more attractive to a wide range of consumers around the world than conventional electric vehicles. Although Volkmar Tanneberger, head of the Group's electronic and electrical R&D, only listed the three main partners of Panasonic, Samsung and LG Chem, it is clear that Volkswagen's battery technology partners are more than these. Tanneberger said that the price offered by Korean battery suppliers is indeed very advantageous, but at the same time Volkswagen is developing a new modular structure of batteries, consisting of 12 battery cells, which can be bag-shaped or prismatic. Or cylindrical.
In addition, Tanneberger's team is still working on combining energy-optimized and power-optimized battery cells into the same battery pack. But Tanneberger said that when the battery pack is being charged, it is difficult to achieve balanced absorption of energy from two different types of battery cells. Such a combination may be attractive in practical applications, and supercapacitors may be a better choice for battery pack energy absorption and release. At the same time, Tanneberger's team is paying close attention to solid-state battery technology, which does not require liquid electrolytes and has broad prospects for the future.
In order to acquire technology in solid-state batteries, Volkswagen invested in the startup QuantumScape. However, Tanneberger believes that solid-state battery technology may have to wait ten years after it is applied to a car. This technology is expected to be the first to be applied to mobile phones and other electric terminal products.
When asked whether there was chassis part sharing between the Volkswagen Group's electric vehicle MEB platform and the comparable size of the MQB A and MQB B platforms, Stefan Gies, head of the public chassis research and development, replied briefly, “Not muchâ€. He said that several modules such as steering gear can be used universally, but important components such as frame rails and crash structures need to be specially built. Because the electric vehicle chassis is low, the battery layout space is large, and the battery in the crushing area does not have the stability characteristics of the internal combustion engine, the front suspension of the MEB model is significantly shortened compared with the more mainstream MQB models.
At the same time, Gies is not optimistic about the prospects of the hub motor. Although the hub motor can save a considerable amount of space for the electric vehicle, the cost of this technology is still very high, and it is difficult to control under severe conditions, and the requirements for the brake system are also high.
