More battery capacity and higher charging power: EV Battery The high-voltage battery system in the new EV (Electric Vehicle) operates with a nominal voltage of 396 volts. Two different battery sizes are available: the battery has a storage capacity of 89 kilowatt hours net (gross: 95kWh), while the two more powerful versions, the have 106 kWh net (gross: 114 kWh). In both cases, the space required for the drive battery is the same; thanks to further developments in cell technology and structure as well as in cell chemistry, the individual cells boast an increased energy density.
