Several technical changes are expected in the large electric sedan Mercedes EQS.

Mercedes is electrifying all its models

In 2018, Mercedes embarked on an electric adventure. To distinguish between petrol/hybrid and electric models in the range, the German manufacturer introduced a new brand called EQ, which means “emotional quotient”. The first 100% electric production model released that year was the EQC SUV, an electric counterpart to the well-known GLC. Later, the Class V (EQV), GLA (EQA) and GLB (EQB) also went through the Volts, before the arrival of the EQS large sedan in 2021. Like the S-Class, it serves as the standard bearer at the top of the Mercedes lineup. By streamlined silhouette and rounded shapes it develops up to 751 horsepower and has a 108 kWh battery, which theoretically allows it to travel up to 785 kilometers on a single charge (in the EQS 450+ version). Mercedes is already preparing its restyling to allow this stay in the game against the latest BMW i7 and many new Chinese premium products from Nio, XPeng and soon YangWang and AITO. Apart from a few aesthetic improvements, mainly technically it will develop the most… What do we already know about this updated EQS?

Mercedes EQS, which will speed up the charging time

The few cross-test prototypes we’ve seen on the roads in recent weeks only hint at that slight retouching of the front and back sides : new specific bumpers, grille and diffusers. The EVA electric platform, which was the first to benefit from it (the EQE, EQE SUV and EQS SUV have since benefited from it), does not undergo any major changes, nor does the range of batteries and motors. The big change will be mainly about power and charging capacity, as it has to replace its 400V architecture with a faster 800V system. By going from 400V to 800V, we double the output power of the battery. A configuration that allows as much speed up the charging speed to the limits that increase the power of the electric motor. To get the equivalent power at 400V would require (and this is what Tesla is currently doing) double the size of the cables to support more currentwhich meets many spatial limitations in an electric car. Audi, Porsche, Hyundai AND Kia already use such a battery architecture, which is currently limited rather a premium make and model. It currently accepts up to 200kW of charging power to charge from 0 to 80% in half an hour.

Therefore, the move to 800 V should allow it to be even more competitive with the competition. Answer in the spring!
