BMW iX xDrive40 charging cable

The BMW iX xDrive40 pairs dual motors and all-wheel drive with a 76.6 kWh battery (71.0 kWh usable) and an 11 kW three-phase onboard charger as standard. An optional 22 kW three-phase charger was available for those who ticked the AC Charging Professional box when ordering. Produced from 2021 to 2025, the xDrive40 has since been succeeded by the xDrive45 in the facelifted iX range, though thousands of xDrive40s remain on UK roads and the charging setup is no less relevant for it. On the standard 11 kW charger, a full charge from near-empty takes approximately seven hours, comfortably within an overnight window. With the optional 22 kW charger and a compatible three-phase supply, that drops to around three and a half hours. DC rapid charging peaks at 150 kW, bringing the battery from 10 % to 80 % in roughly 31 minutes at a CCS rapid charger. The charging port sits on the right rear flank.

Choosing the right charging cable for the BMW iX xDrive40

Most UK homes charge on single-phase power. On a 32A single-phase wallbox, the most common domestic setup for EV owners, the iX xDrive40 draws 7.4 kW regardless of whether the standard or optional onboard charger is fitted. A Voldt® Type 2 22 kW charging cable is rated at 32A per phase, which means it delivers the full 7.4 kW on a single-phase 32A circuit. An 11 kW cable, rated at only 16A per phase, would cap your single-phase charging speed at 3.7 kW: half the rate, for the sake of a cable specification. If your wallbox is a 16A unit, both cables perform identically at 3.7 kW, but the 22 kW cable ensures you are not leaving speed on the table if you upgrade your wallbox later or charge at a public 32A post. At 7.4 kW, a full charge from near-empty takes approximately ten to eleven hours. At 3.7 kW on a 16A installation, that extends to around twenty hours. The difference is large enough that cable choice matters as much as wallbox selection for everyday usability. For owners who specified the optional 22 kW onboard charger and have access to a three-phase supply, less common in UK homes but found at some workplaces and commercial premises, the 22 kW cable is essential to unlock the full charge rate of around three and a half hours from near-empty.

The right-rear port position means reversing into a bay brings the connector closest to the charge point, worth considering when choosing a cable length. A 6-metre cable covers most home setups where the wallbox is mounted near the parking space. An 8-metre cable is the most practical all-round length, handling both home and the majority of public situations without repositioning the car. A 10-metre cable gives useful extra reach at posts set further from the bay or where the port side faces away from the pillar. A 15-metre cable suits long driveways, hotel car parks, and any layout where the geometry works against you.

Portable charging for the BMW iX xDrive40

A Voldt® portable charger with a red three-phase CEE plug (up to 11 kW) matches the standard onboard charger and delivers the full 11 kW from a 16A three-phase supply, charging the 71.0 kWh battery from near-empty in approximately seven hours. Three-phase CEE sockets are uncommon in UK homes but turn up at workshops, farms, and some commercial sites: worth knowing about if you have access to one. Owners who specified the optional 22 kW onboard charger should consider the 22 kW red CEE portable to make full use of 32A three-phase supplies where available. The Voldt® blue CEE portable charger draws up to 3.7 kW from a single-phase 16A CEE socket, the type commonly found at campsites and marinas. A full charge from near-empty takes around twenty hours at that rate, so the blue CEE is best suited to topping up over a longer stay rather than recovering full range in a single session.

The Voldt® three-pin portable charger plugs into any standard UK household socket and delivers up to 2.8 kW, within the limits of what your wiring can sustain. At that rate, charging the 71.0 kWh battery from near-empty takes approximately twenty-seven hours: a practical backup for destinations where no wallbox or dedicated supply exists, not an everyday charging solution for a battery of this size. A built-in thermal sensor monitors the plug and socket temperature throughout the session and adjusts the charging current automatically if things begin to warm beyond safe limits.
