The Mercedes EQS battery has a capacity of 108 kWh. Its production has started, so the car is just around the corner.

Mercedes has announced the start of production of the Mercedes EQS battery and work on prototype cells for electricians. We also found out that the EQS battery capacity is 108 kWh, but it is unclear if this is a utility value or a general value.

• The countdown to the Mercedes EQS premiere is in full swing: battery capacity, drag coefficient, ...
  • Farasis Energy, one of the main suppliers of Daimler, with a cell density of over 0,33 kWh / kg.

During the launch of the Mercedes EQC, the manufacturer used the figure "80 kWh", and over time it became clear that this is a useful value. When the Mercedes EQV electric van was announced, it was initially called “100 kWh” and only later admitted that it was full power because the buyer had 90 kWh at his disposal. Thus, the data is not provided uniformly.

However, even when it turns out that 108 kWh battery Mercedes EQS is an integer value, and the useful value will be, say, 95 kWh, we will deal with the record. Tesla Model S and X today have batteries of around 102 kWh, in theory Lucid and Rivian will offer us more, in practice all these numbers are promises on paper. The same will happen with EQS, at least for some time.

Large battery capacity combined with air resistance coefficient Cx beginning with 0,20 should allow you to reach high ranges on a single charge. The manufacturer's declaration states that "more than 700 WLTP units”(About 600 km in kind), which is again a record. More claims are Tesla with the Model S Plaid+ (837 WLTP units) and Lucid with the Aira Dream Edition (~840 WLTP units), but again, none of these machines are on the market yet.

Farasis Energy, one of the main suppliers of Daimler, with a cell density of over 0,33 kWh / kg.

Out of curiosity, it should be added that around the same time that Daimler disclosed the Mercedes EQS battery data, the Chinese Pharaohs said that he cells of the 4th generation... Their parameters on paper are excellent: they withstand more than 1 complete discharge cycles, retain 90 percent of their capacity at -20 degrees Celsius and, importantly, provide energy density more than 0,33 kWh / kg and more than 0,75 Wh / l. So far, the best cells we know have had 0,3 kWh / kg (source).

The question is important because Farasis is one of the strategic suppliers of lithium-ion cells for Mercedes vehicles. In the near future, they will appear in half of the German manufacturer's electric vehicles offered in Europe. Therefore, we would not be surprised if the announcement of the parameters of the Gen 4 cells were delayed until the date agreed with Mercedes, and if they appeared in the EQS battery [www.elektrowoz.pl assumptions].
