Immited Scars, Volkswagen also held a press conference similar to “battery day”.
On March 15th, the public held the first “Power Day”, at the press conference, the public CEO Herbert Disteganization is elaborated on the overall layout of the public’s new energy vehicle sector.
The Mass Group will adopt intelligent standard cells, which are fully built in 2023, and 2030 will cover 80% of the electric models of the Volkswagen Group. The power battery cost of entry-level electric vehicles will be reduced by 50%.
The public should build 6 battery plants in Europe, and the capacity of each battery plant reaches 40GWH.
In addition, the public also explained in detail in the fields of battery recovery and fast charge networks.
Obviously, the public’s dynamic day is more rich, involving a broader range. Some plans are easy to achieve, and some have a big challenge, still need time.
Because the mass of the Volkswagen Group has nearly 10 million cars, it has an industry leading role in the action of the power battery. Including self-producing batteries, it is possible to compete with the interaction with energy network interaction. In particular, the standard battery can also lead the dynamic battery cells in size, material route, and technical route.
2030 battery demand reached 240GWH
According to the EU Green Agreement, by 2030, the mass of the public will reach 60% in the group, and the amount of battery demand reaches 240GWh / year.
In order to meet this need, the Volkswagen plans to open and run 6 oversized plants, and the average annual production capacity of each plant is 40GWH. The first factory will be the battery factory collaboration with Northvolt, the rest of the factory, and the public will express its expression as “We will pass your own strength and with partners.”
In 2023, the Swedish factory in the public and Northvolt will have 40GWH production capacity, which will be mainly used for the group’s luxury car.
2025, its second 40GWH power battery plant in Salzgite will be put into production. In 2026, the third 40GWH power battery plant will be put into production in Spain or France. In 2027, it will build the fourth 40GWH power battery plant in Poland or Czech Republic of Eastern Europe.
Battery cost is reduced by 50%
Since the battery has a high cost, the public hopes to further reduce the cost of the battery, and the way it adopts the standardized battery cell.
Volkswagen said that they hope that the Group’s 80% models can apply standardized batteries, 20% of models, independent dedicated battery design, which can achieve scale efficiency. The public emphasizes that 80% of the battery standardization is the baseline that cannot be compromised.
From the press conference, the public’s standard battery selection is a square shell battery, which is good for many China’s power battery manufacturers. Because Chinese companies deep tillage casings. The soft bag battery route walking by LG, SK will be hit by South Korea’s LG, SK.
In terms of battery reduction costs, the public also has a clear plan, and they reduce the cost of the battery model by 30%, and the battery cost of the entry-level model is reduced by 50%.
Volkswagen plans to reduce costs from design, manufacturing, materials: 11% reduction in battery design, 10% cost reduction process, 50% of electrode cost, 5% cost reduction in battery system, ultimately Reduce the battery cost by more than 50%.
Solid state battery is the ultimate morphology of the power battery
The Volkswagen covers the lithium iron phosphate battery, high manganese battery, nickel-manganese ternary batteries and solid state batteries.
Volkswagen believes that the biggest advantage of lithium iron phosphate batteries is cost, and there is a slight disadvantage in renewal mileage, but because of its technical maturation and fully verified, it is a very promising technology for low-decisions.
The high-manganese battery is also very promising. Due to the low nickel content and free of cobalt, the cost is also obvious, the renewal mileage also has a relatively advantage, with a large application space.
Material level, the public believes that the silicon-based material is better than graphite performance, and can increase the renewal mileage of 10%, and the charging time is also shorter.
The current battery technology can be filled with 60 minutes, 35 minutes charge 80%; the next step is 50 minutes full, 20 minutes to 80%.
The public believes that solid-state batteries are the ultimate morphology of future vehicle power batteries because they have higher performance and lower cost, and the vehicle from 10-80% of charging time is reduced to 12 minutes.
Battery structure is gradually simplified
In addition to optimization in the electrical core, the public should also optimize the battery system structure, and optimized in the way CTP (no module battery pack) and CTC (integrated electric chassis).
The ultimate goal of the public is to load the battery directly to the model, and there is no need to have the assembly of the middle battery pack. The public believes that such a way will greatly reduce the complexity of the structure, and more excellent performance in light quantization, and you can get a longer battery life.
Battery recovery rate can reach 95%
In addition, the Volkswagen Group pays great attention to battery recycling. In terms of recycling, the mass uses a wet metallurgy process that can be recycled by 95% of the raw materials of the battery.
The public raised an example, taking 400 kg of batteries as an example, reusable materials reached 82 kg. In order to recycle the battery, the public has built a factory specializing in the power battery cell, which has been put into production in January this year.
In 2025, China built 17,000
Volkswagen believes that charging convenience and mileage anxiety are two main factors that currently hinder Chinese customers to purchase electric vehicles.
Volkswagen market surveys and research have shown that about 50% of car purchases in China believe that electric vehicles are inconvenient, and time-consuming is too long; nearly 50% of potential customers believe that new energy models are insufficient. In addition, 40% of the owners cannot install private charging piles.
Summarizing, 81% of charging piles are exchanged slow piles, 30% of the piles are occupied by gasoline vehicles, 30% of damage cannot be used due to maintenance.
The public solution is the CAMS charging station created with FAW, Jianghuai and the stars.
At present, the public has been laid out in Beijing, Chengdu and Shenzhen City, with a total of 40 super charging stations, and the charging power is between 120 kWh to 180 kW, a total of 255 charge stations, including 1800 charging piles.
In 2021, the public will further expand the charging service network. Volkswagen plans to build more than 500 charging stations and more than 6,000 charging piles in China this year, comprehensively covering 8 major cities, with a range of services that can cover approximately 80% of China’s new energy auto market.
By 2025, the Volkswagen plans to amplify the charge pile in China to 17,000, equipped with 120 kW to 180 kW, and even more than 300 kW high-power charging piles, and will cover most of China.
North America, European operators build piles
In North America, the company’s main charging pile operator is Electrified America, as of now there are more than 500 superchants, at the end of 2021, there will be 800 supercharts, 3,500 super charges.
In 2025, the company will also have 17,000 super-charged piles in North America.
In Europe, Ionity is the majority of the main charging network service provider. The company is constructed by the Volkswagen passenger car, Audi, Porsche, Ford, Daimler, and BMW.
In 2020, Ionity already had 325 super-filled piles.
5 million vehicles have V2G functionality
In addition, the public has brought many new charging equipment, including charging robots, charging piles, wall-mounted charging boxes, etc. Among them, the wall-mounted charging box will also have two-way charging function, which is an example of id.3, and it is available for a home for more than 5 days.
By 2030, Volkswagen expected 5 million electric vehicles on the street.
Finally, the public puts forward in the dynamic day, I hope to charge a free charging one day.
