Battery preconditioning optimizes charging performance to minimize charging times Predictive thermal management puts battery cells in the ideal temperature range while approaching a charging station The Audi e-tron route planner provides charging station information – including the number of available stations, payment options, and more Audi offers helpful functions in its electric model series that significantly shorten charging times and make it much easier to find charging stations. The key to optimal charging success There are several basic factors that promote fast charging: Sufficient preconditioning Battery temperature in ideal temperature range of +25°C to +45°C Low state of charge (SoC) at charging start Moderate interior climate control during charging Sufficient power output at charging station How battery temperature affects charging times The temperature of the high-voltage battery (HV battery) has a significant impact on the maximum power output, the charging time, and ultimately the battery’s own service life. In order to ensure optimal charging performance and fast charging stops in low or high outside temperatures, the HV battery must be sufficiently preconditioned. The ideal range for charging the HV battery is between 25 and 45 degrees Celsius. Temperatures above 50 degrees Celsius can damage the battery’s electronics and chemical components. At the same time, temperatures below 25 degrees Celsius increase the battery’s internal electrical resistance, which means that charging will take longer. For this reason, the Q6 e-tron, A6 e-tron, e-tron GT, and Q4 e-tron model series feature a predictive thermal management system designed to put the battery cells in the ideal temperature range while approaching a DC fast-charging (HPC) station. The process of achieving this ideal charging condition is known as preconditioning. It works by heating the battery in cold temperatures and cooling it in warm temperatures.

The Audi Q4 Sportback e-tron derivative has been produced here since summer 2021. For the Four Rings, production in Zwickau is also a return to its roots, which lie in Saxony: to expand his business, company founder August Horch moved to Zwickau, where he had "A. Horch Motorenwagenwerke AG" entered into the commercial register in 1904. This laid the foundation stone for automobile manufacturing in Saxony. Glass recycling in the Audi Q4 e-tron In 2022, Audi and its partner companies launched a pilot project for recycling old car windows. The project aims to recover valuable material from damaged car glass for series production. The car windshield is first shredded in a multi-stage process using an innovative recycling process. The partner companies then sort out all non-glass impurities, such as adhesive residue. The resulting glass granulate is then melted down and processed into new flat glass with the primary material. This is used to make new car windows. Since September 2023, the Four Rings has been using glass with a recycled content of up to 30 percent from car windows that can no longer be repaired for the Audi Q4 e-tron windscreen. Audi is thus successfully transferring the "GlassLoop" pilot project to series production. Audi is the first premium manufacturer to establish such a glass loop in the automotive industry together with partner companies. With this project, Audi and its partner companies are taking up the challenge of establishing a closed material loop for automotive glass1. The project is part of Audi's circular economy strategy. Audi has set itself the goal of increasingly using secondary materials, especially from post-consumer sources, to save resources, energy, and CO₂ - precisely where it is technically feasible, ecologically sensible, and economically viable. 1Audi saved more than 480,000 metric tons of CO₂ equivalents (CO2e) in its supply chain in 2021.

Audi has already shown how this works in practice as part of the MaterialLoop program, for example, by using a proportion of high-quality recycled post-consumer secondary materials for the windshield of the Audi Q4 e-tron (GlassLoop) and the outer roof section of the Audi Q6 e-tron (SteelLoop). Audi is now going one step further with its recycling concept for post-consumer secondary materials. Together with its contractual partner TSR Resource – a specialist in the recycling of end-of-life vehicles – Audi is the first carmaker to ensure that recycled materials are reprocessed for further use in its supply chain. In this specific case, these are high-quality recycled raw materials, such as steel, from preproduction vehicles as well as other sources. Christian Blackert, Managing Director of TSR Resource: “We are delighted to be working with Audi to set another important milestone for the circular economy in the automotive industry. This project is an impressive example of what is possible thanks to industry partnerships. We are also reducing our dependence on fragile supply chains and making an important contribution to resilience in the face of the challenges posed by global markets.” Solution for a strategic, cost-efficient, and sustainable circular economy Closing material loops in industry usually requires several companies to work together. This has advantages for everyone involved: the recycling partner benefits from a predictable incoming stream of end-of-life vehicles and potential buyers of the secondary material. Potential suppliers gain access to high-quality recyclates suitable for the automotive industry at stable conditions – and can pass these on to Audi. In turn, Audi can stabilize its raw material supply chains at improved economic conditions. This makes it possible to increase the proportion of post-consumer secondary material for new vehicles – without compromising on quality or costs.

More sustainability in the supply chain The Audi Q4 e-tron shows in concrete terms what sustainability looks like throughout the life of an Audi vehicle. Producing powerful batteries takes a great deal of energy. This is why, in the production of electric vehicles, nearly half of carbon emissions can be chalked up to the supply chain. To offset this, Audi launched its “CO₂ program in the supply chain” back in 2018. Together with suppliers, the program identified measures for reducing carbon emissions. For example, certified green electricity is used for the production of the Audi Q4 e-tron’s cells – and suppliers commit to this by contract. Another example of how Audi is bringing more sustainability to the supply chain is secondary materials. Audi returns the aluminum scraps from the press plant to the supplier for processing and then gets them back in the form of newly processed aluminum coils. This means less primary aluminum is necessary, and less carbon is emitted. The Aluminum Closed Loop has avoided more than 780,000 tons of net carbon emissions3 since its introduction This means less primary aluminum is necessary, and less carbon is emitted. The Aluminum Closed Loop has avoided more than 780,000 tons of net carbon emissionssince its introduction in 2017. In the meantime, the plants in Neckarsulm, Ingolstadt, and, since 2021, Győr in Hungary, as well as the Volkswagen site in Bratislava, are implementing the "Aluminum Closed Loop". Green power in the utilization stage The greatest potential for fully leveraging the advantages of electric drive systems lies in the utilization stage. In addition to the fact that electric cars don’t emit carbon on the road, the electricity used for charging is a decisive factor here. In their garage at home, customers can charge the Q4 e-tron with green power, for example, using Volkswagen Naturstrom, a sustainable electricity solution provided by “Elli”, a subsidiary of the Volkswagen Group.
