At Auto Shanghai 2023, the largest automotive tradeshow in China, Audi will be appearing at a joint booth together with its local partners First Automotive Works (FAW) and SAIC Motor. There, in line with the brand's commitment to sustainability and local market trends, visitors will be greeted by a selection of exclusively all-electric Audi vehicles. The F1 show with Audi launch livery as well as the Audi A6 e-torn Avant concept and the Audi urbansphere concept - all displayed publicly in China for the first time - are further highlights. Thus, the brand’s exhibits at the motor show stand for Audi’s China approach: It is characterized by products and services developed ‘in China for China’ as well as a holistic ecosystem.
The lights on an Audi have long provided more than just safety. They represent the interface between design and technology and they have an authoritative impact on every Audi model’s visual appearance. That is particularly distinct in the exterior design of the e-tron GT quattro and RS e-tron GT – headlights and taillights are defining elements of these models.
You need powerful thermal management for high and reproducible output. In the e-tron GT, there are two coolant circuits for the technical components operating on different temperature levels. The cooler one controls the temperature of the high-voltage battery and the warmer one serves the electric motors and power electronics. Plus, there’s a cold circuit and a heating circuit for the interior, which I suppose your race car doesn’t have.Prediction is important in our case, too, albeit on a different level. We use a special functional feature to ensure that the driver can charge the battery with utmost capacity during a trip. When the car travels a longer distance with active navigation, the e-tron route planner issues suggestions of where to charge the battery. About half an hour before the car arrives at the selected charging station, the thermal management system starts adjusting the temperature of the battery to precisely match its state of charge and the charging station’s capacity.
On long-distance routes, the Audi e-tron Sportback 55 quattro can charge with direct current (DC) at up to 150 kW at fast-charging stations. In just under half an hour, the battery reaches 80 percent of its capacity-sufficient for the next leg of its long-distance trip. The e-tron Sportback 50 quattro can charge at up to 120 kW and achieves an identical charge status in the same time. Charging at public AC charging stations can be performed using a standard mode-3 cable. Up to 11 kW of power is available here, which can be increased to 22 kW with an optional second on-board charging device that will be available in summer 2020. Audi's own charging service, the e-tron Charging Service, provides easy access to almost 120,000 public charging points in 21 European countries - and the number is rising. Whether AC or DC, 11 or 150 kW-a single card is all that is required to start the process. The Plug & Charge function, which is also due to follow in 2020, will make charging even more convenient: The car authorizes itself at the charging station and activates it. The highly flexible thermal management, which comprises four separate circuits, regulates the temperature of the high-voltage components with maximum efficiency. This enables rapid DC charging, a long battery life cycle, and reproducible performance even under heavy loads. The standard heat pump, which harnesses waste heat from the high-voltage battery, can use up to 3 kW of actual power losses for heating and air conditioning the interior-which is exceptionally efficient. Depending on the outside temperature, that can boost the Audi e-tron Sportback's range by up to ten percent in customer operation.

The standard compact charging system is suitable for a simple 230-volt connection and for a 400-volt three-phase outlet with an output of up to 11 kW. The optional charging stem connect will be available for ordering at market launch. It offers smart charging functions, for example preferred charging at low-cost times. The combination with a suitable home energy management system allows the vehicle to be charged preferably with self-generated solar power, provided that the house is equipped with a photovoltaic system.
