The EQS marks the launch of a new generation of batteries with significantly higher energy density. The larger of the two available batteries has a usable energy content of 107.8 kilowatt-hours. The in-house battery management software allows updates over the air (OTA). This keeps the energy management system to remain up-to-date throughout the life cycle. In terms of cell chemistry, the cobalt content of the cathodes has been reduced to 10 percent.
