4. Now that you're talking about the mid-control interior, just talk about its network connection system. The Audi e-Tron is equipped with its own in-car multimedia system MMI, which can perform entertainment, communication, information, control, and other operations, and supports 4G/WiFi, voice interaction and touch screen control. It seems to be feature-rich, however, it is now 2018, these features should be the most basic function of a car, like Amazon's Alexa voice assistant to query the charging situation may just add a little color to the e-Tron. But there is no substantial value.
Moreover, Audi did not mention OTA-related information at the press conference, and the L3-level autopilot function on the Audi A8 was also absent from the e-Tron. Therefore, although there are two electronic rearview mirrors, the performance of this car in terms of intelligence is not as good as that of Tesla. This is not surprising. After all, the transformation of traditional car companies requires a process.
5. Regarding the cruising range of this car, it is only known that under the WLTP standard, the e-Tron can reach 400 km of battery life, and the EPA working condition has not been announced yet. Compared to the NEDC battery life, the WLTP standard can better reflect the actual car situation. From September 1st, the EU has begun to use the WLTP standard to replace the current NEDC standard. The Mercedes-Benz EQC, which was released earlier than it, achieved 450-kilometer NEDC life with 80-degree power. The current Model X 75D (battery capacity 75kWh) NEDC has a cruising range of 406 kilometers, and the Model X is larger than the e-Tron in body size. In some cases, comparing the two cars, the range of more than 400 kilometers (NEDC standard) may be worse on this 95-degree SUV, and how much discount will be used in actual use. not sure.
It is worth mentioning that Audi particularly emphasizes the e-Tron's kinetic energy recovery system. According to the official statement, after the start-up can be recycled, it can increase the cruising range by 30%, but the actual effect is determined by factors such as weather and road conditions.
6. After you finish your life, talk about charging it. The e-Tron supports up to 150kW of fast charge. It takes only 30 minutes to rush from 0 to 80%. Although it is higher in terms of charging efficiency, it will take some time for the 150kW charging pile to become popular. Audi gives the data compared with the competing models, and also charges 30 minutes, how far can the three cars travel? Look at the picture below
The Mercedes e-Tron has a battery pack capacity of 95 kWh and consists of 36 battery modules. Each battery module consists of 12 60Ah batteries, for a total of 432 batteries. The battery pack is tiled on the chassis, and as can be seen from the figure, Audi uses aluminum frame and beam structure design to enhance the safety of the collision in the design of the battery protective case and also considers the weight reduction of the battery.
When charging, due to different charging methods, different heating sources, different heat sources, the cooling method used is different (a bit of a mouthful). When using AC charging, energy enters the battery through the high-voltage charger, and the high-voltage charger is the main body of heating. At this time, the liquid cooling heat starts; when DC charging is used, the energy directly enters the battery, and then the battery becomes a heating main body, at which time the heat is dissipated by the caulking agent and the thermal conductive gel.
While driving, the battery management system selects the different cooling methods to keep the battery in a suitable temperature zone.
In foreign countries, e-Tron's batteries are soft pack batteries supplied by LG Chem, while domestic suppliers are in the Ningde era.
