During the 2021 IAA Munich Motorshow BMW displayed a cut iX to show its batteries and electric engines.

More about the iX's batteries

High-voltage battery with the very latest battery cell technology.
Fifth-generation BMW eDrive technology also includes a high-voltage battery with state-of-the-art battery cell technology. Its volumetric energy density at cell level is up by around 40 per cent compared to the high-voltage battery in the 2020 BMW i3. The BMW iX xDrive50 is fitted with a high-voltage battery with a net energy content of 105.2 kWh (gross energy content: 111.5 kWh), while the battery unit for the BMW iX xDrive40 has a net energy content of 71 kWh (gross energy content: 76.6 kWh).

The standard specification of the BMW iX includes an integrated heating and cooling system for the cabin, together with its high-voltage battery and a drive system that operates using an exceptionally efficient heat pump function. Anticipatory thermal management enables the high-voltage battery’s operating temperature to be optimised for quick and efficient charging prior to a scheduled stop at a fast-charging station.

The Combined Charging Unit (CCU) in the BMW iX has been designed to offer a very high level of charging flexibility. DC power can be taken on board at a rate of up to 200 kW (BMW iX xDrive50) or 150 kW (BMW iX xDrive40). This allows the battery’s state of charge to be increased from 10 to 80 per cent in around 35 minutes in the BMW iX xDrive50 or 31 minutes in the case of the BMW iX xDrive40. What is more, range can be increased by up to 150 kilometres (93 miles) for the BMW iX xDrive50 and over 95 kilometres (59 miles) for the BMW iX xDrive40 in just ten minutes when they are plugged into a DC fast-charging station with an initial battery charge of 10 per cent. BMW iX models in Europe are supplied complete with a BMW Charging Card, the Flexible Fast Charger offering a charging rate of up to 11 kW and a mode 3 charging cable for public charging stations. The special tariff system offered by BMW Charging allows electrical power to be replenished at a very attractive price at both public charging stations and high-power charging stations.
