The fifth generation of BMW eDrive technology also includes a high-voltage battery with the latest battery cell technology. Its volumetric energy density at cell level is around 40 percent higher than in the high-voltage battery of the BMW i3 from model year 2020. The BMW iX xDrive50 has a high-voltage battery with a net energy content of 105.2 kWh (gross energy content: 111.5 kWh) amounts to. The storage unit designed for the BMW iX xDrive40 has a net energy content of 71 kWh (gross energy content: 76.6 kWh). An integrated heating and cooling system for the interior, the high-voltage battery and the drive, which operates with a particularly efficient heat pump function, are part of the standard equipment of the BMW iX. Predictive thermal management makes it possible to optimize the operating temperature of the high-voltage battery for fast and efficient charging in good time before stopping at a fast charging station
