Mercedes is engaged on upgrading the EVA 2 platform to enhance its effectivity.
Mercedes officers aren’t pleased with gross sales of the luxurious electrical fashions, falling far in need of expectations, and they’re planning to improve the EVA I2 platform used within the EQE/EQS and spinoff SUVs.
On the launch of the Mercedes EQS, within the two-motor, all-wheel-drive electrical variations, each everlasting magnet synchronous motors have been working repeatedly, resulting in larger power consumption. Mercedes EQS two-motor fashions to any extent further may have a clutch that enables the entrance motor to be disconnected when extra energy or extra traction is just not wanted.
Clutch engagement and disengagement ought to be very easy, and, due to this fact, the velocity distinction between the wheels and the engine ought to be as small as attainable.
Mercedes selected the answer with a synchronous motor on the entrance axle and clutch for decoupling as an alternative of an asynchronous motor that isn’t powered when not beneath load as a result of they discovered it’s as much as 6% extra power environment friendly.
Decoupling the entrance motor saves power and will increase vary. German automotive journal auto motor und sport carried out a spread check with the Mercedes EQS 580 4Matic outfitted with the entrance engine decoupling system, which lined 601 km between prices in eco mode in comparison with 560 km earlier than.
The rise in vary was achieved regardless of modified Mercedes EQS 580 4Matic fashions are 46 kg heavier as a result of introduction of the clutch and warmth pump. Mercedes engineers haven’t launched warmth pump to this point, contemplating it has benefits solely in sure respects.
A further condenser has additionally been fitted within the water circuit to make extra environment friendly use of the engine’s waste warmth.
With the introduction of the clutch to the entrance engine, Mercedes has elevated the output of the EQS 580 4Matic from 523 to 544 ps, the identical because the EQS 580 4Matic SUV.
The battery capability may also be elevated sooner or later. The usable capability of the massive battery will improve from 108.4 kWh to 118 kWh, and the small battery from 90.6 to 96 kWh in case of EQE.
Mercedes says it has additionally solved the issue of inconsistent brake pedal suggestions, and restoration can be lively when the brake pedal is depressed (aside from emergency braking), with a really excessive restoration power energy of as much as 290 kW.
The German premium producer has additionally been conscious of criticisms in regards to the high quality of supplies in comparison with the S-Class and can supply higher high quality supplies on seat backs and different areas. It would additionally introduce an indicator displaying the remaining battery degree in p.c.
Oliver Rocker, head of the EVA II platform mannequin vary, confirms what we wrote just a few days in the past, that the 2025/2026 facelift will see the introduction of the 800V structure, which might be used additionally within the new compact fashions constructed on the brand new MMA platform.
Nonetheless, 800V expertise is just not attainable with no new battery as a result of the chemistry of the battery cell should stand up to a better charging voltage. Rocker says the EVA 2 platform should stay technologically superior. This strategy is logic as a result of it doesn’t make sense that the platform for brand spanking new compact fashions working at 800V ought to be extra superior than the one for luxurious electrical fashions.
