If the navigation system’s route guidance function is active and has scheduled a stop at a fast-charging station, anticipatory thermal management will automatically pre-condition the battery beforehand. The integrated heating and cooling system also insures optimal temperature control for the high-voltage battery in highly dynamic driving situations with high power requirements and during fast-charging from a DC charging station. "The latest version of the heat pump achieves a high efficiency factor by making use of ambient heat and heat from dehumidification – as well as the waste heat from the motors – for energy-efficient operation. A two-level cooling module, a refrigerant compressor, two evaporators, a water-cooled condenser and a high-performance control unit together ensure optimum temperature control for both the BMW eDrive components and the vehicle interior in any operating state and in all regular weather conditions." While driving in low outside temperatures, for example, the excess heat generated by the drive units is used to warm up the high-voltage battery. "The BMW iX’s heating and cooling system is made up of three cooling/heating circuits that can be interconnected by means of electric valves with a shared expansion tank. There is a battery pre-conditioning feature ahead of fast charging. The vehicle has an advanced thermal management system - heating and cooling with heat pump. According to BMW, the gravimetric energy density of the lithium-ion battery has been increased by around 20% compared to the previous generation (no numbers were provided).ĭepending on wheel size and type, the EPA range will vary from 305 miles (491 km) to 324 miles (521 km).
