Mercedes EQG EV SUV to get high silicon content battery

The EQG EV SUV, based on the G-Class, will have many firsts, including motors to simulate the effect of the three differential locks like the standard SUV.

Mercedes-Benz is readying an all-electric G-Class which was previewed sometime back as the EQG concept. This new SUV will have multiple innovative tech, including the brand’s new energy dense battery cells.

Mercedes-Benz EQG: battery tech 

Insiders have confirmed to our sister publication Autocar UK that the electric off-roader, which is due to be launched in 2025, has been earmarked first for the battery technology previewed by the one-off EQXX saloon concept. This tech will then be used in other forthcoming Mercedes EQ models.

The new battery has been developed in partnership with US company Sila Nanotechnologies. It features a silicon anode that, in combination with other chemical changes in the cells, is said to contribute to a 20-40 percent increase in energy density compared with the batteries used in the existing line-up of EQ models, which feature more commonly used graphite anodes.

Mercedes-Benz says the new cell chemistry allows it to store “more electric energy in any given space than is the case now”. This will allow it to increase the range of future models without resorting to larger-capacity batteries. The prototype battery used by the EQXX is said to have a capacity of 100kWh, compared with the 90kWh and 107.8kWh batteries currently available for the EQS. The battery in the EQXX is said to weigh 495kg.

The basis for the EQG is a modified version of the existing Mercedes-Benz G-Class’s ladder-frame chassis, which has been comprehensively reworked to support the extra weight of the battery. The electric G-Class is set to be powered by a quartet of electric motors – two at the front and two integrated into the rear axle assembly, and each with its own fixed-ratio gearbox. A software package being developed by Mercedes is said to enable the motors to simulate the effect of the three differential locks featured on the combustion-engined G-Class models.

Mercedes EQ line-up in India

As far as Mercedes EQ range goes in India, the EQC is already on sale and has had its first batch sold out. The Mercedes-AMG EQS 53 4Matic+ was recently launched here, while the Mercedes-Benz EQS 580 is scheduled for a launch on September 21. Additionally, the carmaker will also introduce the EQB three-row electric SUV in India in the near future.
