BMW i7 charging cable

The BMW i7 is a full-size luxury saloon built entirely around an electric powertrain. The eDrive50, xDrive60, and M70 xDrive all carry the same 105.7 kWh battery (101.7 kWh usable), the same Type 2 CCS charging port on the right rear flank, and the same 11 kW three-phase onboard AC charger as standard, with an optional 22 kW three-phase charger available across the lineup. Where the variants diverge is in drivetrain layout and output. The eDrive50 is rear-wheel drive with a single motor producing 335 kW. The xDrive60 adds a front motor for all-wheel drive, raising combined output to 400 kW. The M70 xDrive is the performance flagship: 485 kW, 1,100 Nm, 0–100 km/h in 3.7 seconds, and a top speed of 250 km/h. DC rapid charging peaks at 200 kW across all three, covering 10–80 % in approximately 35 minutes. On the standard 11 kW AC charger, a full charge from near-empty takes approximately ten hours on every variant. With the optional 22 kW charger and a compatible three-phase supply, that drops to around five hours.

Selecting your i7 charging cable

Most UK homes charge on single-phase power. On a 32A single-phase wallbox, every i7 variant draws 7.4 kW regardless of which onboard charger is fitted. A Voldt® Type 2 22 kW charging cable is rated at 32A per phase and 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, purely because of the cable specification. On a 16A wallbox both cables deliver 3.7 kW equally, but the 22 kW cable keeps you ready for a wallbox upgrade, a public 32A post, or a future vehicle with a higher-capacity charger. Owners who specified the optional 22 kW onboard charger and have access to a three-phase supply will want the 22 kW cable to unlock the full charge rate of around five hours from near-empty.

The right-rear port is consistent across eDrive50, xDrive60, and M70, so reversing into a bay brings the connector closest to the charge point on every variant. The i7 is a large car and parking positions are not always predictable, so choosing the right cable length from the start avoids any issues later. A 6-metre cable covers most home setups where the wallbox sits near the parking space. An 8-metre cable is the most practical all-round length for any i7, 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.

Charging away from your wallbox

A Voldt® portable charger with a red three-phase CEE plug (up to 11 kW) matches the standard onboard charger fitted to every i7 and delivers the full 11 kW from a 16A three-phase supply, charging the 101.7 kWh battery from near-empty in approximately ten hours. Three-phase CEE sockets are uncommon in UK homes but can be found at workshops, farms, and some commercial premises. Owners who specified the optional 22 kW onboard charger should consider the 22 kW red CEE portable charger 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 found at campsites and marinas across Europe, and suits topping up over a longer stay.

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. For a car of this calibre, the three-pin charger comes into its own at destinations where the i7 sits for an extended period: a weekend away, a longer work trip, or any stop where every kilowatt-hour added extends the next leg of the journey. A built-in thermal sensor monitors the plug and socket temperature continuously and adjusts the charging current automatically if things begin to warm beyond safe limits.
