The charging speed of the Mercedes-Benz EQS and has been compared to other luxury electric vehicles (EVs), revealing competitive results, but not top-notch.

Mercedes-Benz EQS 450+ is an ultra-luxury rear wheel drive electric sedan featuring 107 kWh battery capacity, but only 200 kW max charging power and 400V architecture, which is odd for such a technologically advanced car brand.

The Mercedes EQS DC fast charging test was performed by Kyle Conner for the out of Spec Reviews YouTube channel.

Kyle used the EVgo charging station rated at 350 kW and 500 A max power output. Data shown at the charger’s display and the car’s display are slightly different. Kyle compared the charging behavior with other high-end electric models, like Tesla Model S Plaid and Lucid Air.

Charging power in the EQS quickly raises to the max of 200 kW and remains there until about 1/3 of total battery capacity. From 10% to 80% of capacity it fills up the battery in 31 minutes.

In comparison with it rivals Tesla Model S Plaid and Lucid Air, there is a big difference in the power level in the first half of charging.

After 50% battery level, the charging curves are quite similar to each other. You might think that the EQS charges much slower due to this. Actually that’s not true. Within 20-80% state of charge the charging time is almost on par with Tesla and Lucid.

The EQS average charge time between 20-80% SOC is 13.3 km/min (8.3 mi/min) – slightly less than Model S Plaid.

Conclusion
Mercedes-Ben EQS 450+ is one of the fastest charging EVs on the market today. However, not as fast as the the Tesla Model S Plaid or the Lucid Air.

The 200 kW peak power input and just a 400V architecture make it charge a little bit slower than expected from a car that has been long considered a king of the automobiles – the Mercedes S Class. An upgrade to a 800V battery system could bring it to the top of the list.
