In the United States, starting this year, there will be carrots in the form of block benefits Hundreds of billions for domestic production of batteries and electric cars, the European Union is trying it with a whip at the moment: at the beginning of 2024 a new battery regulation will come into force, which will require, among other things, comprehensive information about each installed battery and subsequent compliance with ESG standards. Basic data should be collected and presented in a standardized manner. Tesla and Audi have now published the first examples of these battery passports.
Audi battery for the new electric car?
The information published by the Global Battery Alliance is still incomplete. Tesla made it available to the battery pack that can power most of the company’s electric cars: a 78-kWh pack, made up of Chinese-made batteries from LG Energy Solutions and then In Tesla China for the final battery and in the Model 3 and Model Y. Installed in the long run and performance versions. The passport form states, among other things, that it contains 4416 individual batteries and that it weighs 481 kilograms.
Audi has First passport data It was even issued for two batteries, and one of them is unusual in two ways: First, the cells in it are said to come from Samsung SDI in Hungary – a laudable exception in terms of the EU’s goals, since the vast majority of batteries are still produced in Asia and especially China. Secondly, the rated power of 114 kWh. An Audi electric car with such a large battery does not exist yet. So passport information could confirm reports that the Q6 e-tron and its brother, the Porsche Macan, have plenty of capacity.
to update: Readers noted that the new Audi battery for the Q8 e-tron, successor to the previous e-tron can be provided. Its net capacity was estimated at 106 kWh when it was announced last November, which could correspond to the 114 kWh gross value in the passport.
Audi’s second battery, like Tesla’s, is likely to be in a car series: 100 kWh with NMC cells from CATL from China, which became the battery in Germany and which is intended for a German-produced electric car. chat Audi e-tron GT, which also has a close team relationship with the Porsche Taycan she has. This package consists of only 180 prismatic cells and is said to weigh 580 kg.
Tesla gives data on the carbon dioxide footprint
In addition to this basic data, which in the future will have to be accessed directly from the QR code on each battery, Tesla and Audi have isolated more in-depth information from the Battery Alliance. At least that’s what Tesla calls its cobalt supplier — the battery comes 100 percent from a subsidiary of Glencore in the Congo. In the case of Audi batteries, this material makes up a much larger proportion and also comes mostly from the Congo, in this case from two unnamed producers described as large. Tesla also mentions the carbon footprint of its battery, depending on the method at 74 or 77 kilograms per kilowatt-hour, while Audi says this data is “protected”.
