A BMW i7 charging cable has to move more energy than any other cable BMW owners buy from us. The i7 carries 101.7 kWh of usable battery and accepts up to 22 kW on AC, three phase, standard on cars built from 2023. The very first xDrive60 deliveries in late 2022 were quoted at 11 kW. Battery size does not vary across the eDrive50, xDrive60 and M70 xDrive, so the charging answer is the same for all three.
Every BMW i7 uses a Type 2 to Type 2 Charging Cable. The inlet on the offside rear combines the Type 2 AC connection with the DC pins, and the AC half is what a home or destination charger uses.
The size of that battery is what makes the cable choice matter here. Paying for a three phase cable to use on a house supply buys nothing: the i7 will draw 7.4 kW from it and 7.4 kW from the single phase cable that costs less, because a British domestic feed carries one phase. What the battery does change is the cost of getting the cable wrong. A 32A single phase cable is the sensible home choice and takes the i7 from empty in about 15 hours 30 minutes, which is already two overnight windows rather than one.
Step down to a 16A cable and the same job takes 31 hours. In practical terms that is around 14 miles put back per hour instead of 28, so a seven hour off peak window returns about 98 miles rather than 196. On a car with this much battery, a 16A cable never catches up with normal use and the saving disappears inside a month of charging.
Because a full charge is a long job, most i7 owners top up rather than fill. That makes a Type 2 to 3 Pin Charging Cable more useful than it first looks. At 2.3 kW it adds roughly 9 miles an hour, so an afternoon on a 13A socket at a relative's house is worth something, and it removes the risk of arriving somewhere with no working post.
Other large BMWs in the range include the BMW i5 and the BMW iX, both of which take the same cable. You can see everything we stock on the BMW EV charging cable range.
Our cables are built to IEC 62196, CE certified, and rated to run between -30C to +50C, or +60C for the 3-pin. The Type 2 to Type 2 cable is sealed to IP55 and the Type 2 to 3 Pin to IP67. A 2 year manufacturer's warranty covers every one, and UK delivery is free and next working day.
Maximum onboard AC charging speed: 22 kW three phase on cars from 2023, 11 kW on the earliest xDrive60 deliveries.
| Cable Type | Max Charge Rate | Empty to Full | Range Added Per Hour | Verdict |
|---|---|---|---|---|
| 16A Type 2 to Type 2 | 3.7 kW | 31 hours | approx. 14 miles | Too slow for this battery |
| 32A single phase Type 2 to Type 2 | 7.4 kW | 15 hours 30 minutes | approx. 28 miles | Best Fit at home |
| 32A three phase Type 2 to Type 2 | 22 kW | 5 hours 15 minutes | approx. 84 miles | For 22kW posts and workplaces |

Compatible with all Type 2 cars
A BMW i7 takes a Type 2 to Type 2 charging cable, and the 32A single phase version suits nearly every owner. It carries the full 7.4 kW a domestic wallbox provides and refills the 101.7 kWh battery in about 15 hours 30 minutes. We stock it in 5m, 10m, 15m and 20m.
No. A BMW i7 can accept 22 kW, but only from a three phase supply, and houses in Britain are fed with a single phase. At home the car takes 7.4 kW through either cable. The three phase cable is worth owning if a workplace or destination charger you use often runs three phase AC, where it cuts a full charge to about 5 hours 15 minutes.
A BMW i7 takes roughly 15 hours 30 minutes from empty on a 7.4 kW home wallbox with a 32A single phase cable, and about 5 hours 15 minutes on a 22 kW three phase AC supply. Very few owners run the battery flat, so a nightly top up of 150 to 200 miles is the more useful number.
The BMW i7 is close to 5.4 metres long with the charge flap on the offside rear wing, so parking direction changes the answer more than it does on a smaller car. Reversing onto a drive with a wallbox by the house usually works with 5m, while nose in parking or a charger on the opposite wall of a garage points to 10m. It is worth measuring the actual run before ordering.
Many BMW i7 cars were supplied with a single phase cable, and it will not use the car's 22 kW three phase charger. It is also common for the supplied cable to be shorter than a driveway needs. A second cable in the boot means a public post is never a problem when the first one is plugged in at home.
A 16A cable will charge a BMW i7 but it halves the rate to 3.7 kW, stretching a full charge to 31 hours and returning around 14 miles for each hour on the plug. On a battery of 101.7 kWh that difference shows up every night, so the 32A cable is the better buy.

Every i7 is fully electric, and the i7 has the fastest AC charging of any BMW: 22 kW as standard in the UK. That only pays off on a three-phase supply. On a normal single-phase home wallbox the car charges at 7.4 kW like everything else. The petrol and diesel 7 Series has no charging port. Trim level makes no difference to charging.

Cable Length:
Sizing guideWe offer different length cables to suit your needs, whether you park next to your charger at home or at the office.
Rated Power (Charge Speed):
How do I Choose?Rated power is the fastest the cable can charge. Match it to your car and your charge point. A higher rated cable still works at every lower speed.
Accessory Add-Ons
We offer a range of products to help store and transport your charging cable. Choose from the accessories below:
A charging cable that connects electric vehicles (EVs) with a Type 2 connector to charging points is also equipped with a Type 2 socket. It supports faster charging speeds and is commonly used across Europe for EVs with this standard connection.
This cable allows electric vehicles with a Type 2 socket to charge from a standard UK 3-pin domestic outlet. It provides a slower charge but is useful for home or emergency charging when dedicated charging stations aren't available.
A cable used to extend the reach of a Type 2 charging cable. It's helpful when the existing cable is too short to connect an electric vehicle to the charging point, providing more flexibility in parking.
A fixed charging cable attached to a charging point, designed for electric vehicles with a Type 2 socket. The tethered design eliminates the need to carry a separate cable, offering convenience for regular charging at home or work.
A charging cable that connects electric vehicles with a Type 1 socket to charging points equipped with a Type 2 outlet. This allows EVs with the older Type 1 standard to use more modern charging infrastructure.
This cable enables electric vehicles with a Type 1 connector to charge from a standard UK 3-pin household outlet. It's suitable for slower charging at home when dedicated EV charging points aren't accessible.
A 5M charging cable is the shortest length that we offer. It is a great option if you can park close to the charge point and do not need much length to reach your car.
A 10M charging cable is the most popular length. It allows you to have enough flexibility whilst still being easy enough to move. This is a great option if you cannot park close to the electricity supply.
A 15M charging cable is a great choice if you need some extra flexibility, i.e. get past another car or reach the other end of a driveway. The length of the cable does not affect the charging speed.
A 20M charging cable is the longest cable that we currently offer. 20M reaches the vast majority of locations where you would want to charge your car. Always use one continuous cable. Never join two charging cables together and never charge through an extension lead, because the join is where heat builds up.
The choice if you will charge from a standard UK 3 pin socket. It runs at the most the socket can safely supply, and the control box lets you turn the current down for a slower, gentler charge overnight or on an older circuit.
A 16amp cable will be able to charge at 3.7kW. This is the cheapest product if your car's max charge speed is 3.7kW. If you have two electric cars or are looking to purchase another it might be worth considering a faster charging cable as this could limit charge speeds moving forward.
A 32amp charging cable will be able to charge at 7.4kW, which is the most a single phase UK home supply can deliver. A 32amp cable also charges at every lower speed (for example 16amp, 3.7kW), so it is the right choice if your home charge point is 7.4kW or you mostly charge at home.
A 32amp 3-phase charging cable will be able to charge at all speeds up to 22kW, so the cable never limits your charge speed at home or in public. It is also capable of charging at all lower charge speeds.
