Volkswagen Group China building battery system factory in Anhui to strengthen BEV value chain
24 September 2021
Volkswagen Group China is commencing construction of a battery system production factory in Hefei (Anhui province). VW Anhui Components Company is the first battery system plant to be wholly owned by the Group in China. The initial annual capacity will be 150,000 to 180,000 high-voltage battery systems for Volkswagen Anhui’s all-electric vehicles based on the Group’s Modular Electric Drive Toolkit (MEB platform).
With an area of more than 45,000 square meters, the plant will be located next to the production facilities of Volkswagen Anhui, Volkswagen’s first majority-owned joint venture for all-electric vehicles. Volkswagen Group China is investing more than €140 million until 2025 in the new plant and its facilities, with the start of production (SOP) targeted for the second half of 2023.
Volkswagen Group's platform strategy is a competitive advantage which we are transferring into the e-mobility era. With a significant increase of battery-electric vehicles (BEVs) in the future, we need to focus on keeping key components like battery systems in our own value chain, allowing us to leverage Group-wide synergies and innovations. Volkswagen Anhui and VW Anhui Components Company, alongside our two strong Joint Ventures, are crucial to our electrification strategy and to achieving our goal of the Volkswagen Group China fleet reachingover 40% NEVs by 2030.—Dr. Stephan Wöllenstein, CEO Volkswagen Group China
The development and production of battery systems is a crucial step on the way to achieving end-to end responsibility for the battery. Thus, Anhui is an important pillar of our global battery strategy. The global strategy leads from vertical integration in the raw material market via building battery plants, as well as cell factories in collaboration with partners—amongst them the Chinese battery expert Gotion—to second life solutions and recycling.
Currently, we are building up three MEB battery manufacturing facilities in Asia, Europe and the USA to be able to meet the growing demand for MEB battery systems in the future. Our blueprint factory in Braunschweig, Germany, is ready to produce up to 500,000 battery systems a year and is assisting in our capacity build-up with its expertise in planning, development and production.—Thomas Schmall, Volkswagen Group Board Member for Technology and CEO of Volkswagen Group Components
The new plant, VW Anhui Components Company, will be located in the nearby supplier park of Volkswagen Anhui’s EV-production site, which brings logistical and cost efficiencies and a faster time-to-market. The
The new plant will leverage existing synergies with the Group’s wholly owned battery plants and workshops in Braunschweig (Germany) and Tianjin (China), as well as enhance ties and synergies with the MEB battery plants of Volkswagen Group’s Chinese Joint Ventures.
The Braunschweig plant is the lead plant for the planning, development and production of battery systems. Experts from Germany provide support at the international facilities currently being set up, including in Anhui. The experience gained at the Braunschweig plant, which has been running since 2019, is thus transferred across the Volkswagen Group. In addition to experts working on site, there are also teams working from Germany as bridgeheads in the collaboration. At the same time as Anhui, battery assembly capacities are also being set up in the Czech Republic (Mlada Boleslav) and in the USA (Chattanooga). The plan is to manufacture more than 1 million battery systems per year in a few years.
The battery system for MEB vehicles consists of several cell modules, a cell management controller, a battery management system, and a connector strip, which are interconnected via high-voltage connectors and protected in an aluminum battery housing.
In terms of the manufacturing process, there will be two production steps each with two production lines—one for frame production and one for system assembly. Consistent with the Group’s vision for a digitized manufacturing process, the production, assembly and testing of the battery systems will utilize advanced technology and involve a high level of automation at each stage. Prototype production has already started at the Group’s Tianjin plant.
