The Combined Charging Unit in the BMW iX1 xDrive30 enables single- and three-phase AC charging up to 11kW, optionally increased to 22kW (three-phase AC). This allows the battery to be fully recharged from empty in 6.5 hours as standard and just 3 hours 45 minutes as an option. DC recharging at up to 130kW makes it possible to boost the battery level from 10 to 80 per cent in 29 minutes, or increase range by 75 miles in just 10 minutes.

As in the BMW i7, the charging software has been further refined. Once the battery reaches a higher charge level, the new process drops the charging rate smoothly instead of the previous “stepped” curve, resulting in even shorter charging times.

An optimised cooling strategy for DC charging improves the durability of the battery. Alternating phases of full and partial cooling power are used to prevent cell temperatures dropping too low during fast charging, shortening charging times and reducing ageing. Customised settings for individual charge points can be stored and automatically recalled on the next visit, while preheating can be started manually on approach to a DC charging station.
