Two plug-in 7 Series share this page: the 740e, 740Le and 740Le xDrive iPerformance of 2016 to 2019 with a 9.2 kWh battery, and the 745e, 745Le and 745Le xDrive of 2019 to 2022 with 12 kWh. Both charge through a Type 2 inlet, and BMW never published an AC rate for either, so we judge them by what the packs actually do. A 745e is full in about 3 hours 20 minutes on a 16A lead and in exactly the same time on a 32A one, which shows the car, not the cable, setting the pace. A single phase UK home can supply 7.4 kW, and neither car comes close to using it.
A 16A Type 2 to Type 2 lead is light enough to coil neatly into a 7 Series boot, and it is also the cable to reach for at a hotel car park or any public post without a lead of its own. Measure from the wallbox to the flap with the car where it normally stands: the 15m and 20m cables are made in 32A single phase only, which on these cars buys reach rather than speed, useful for a car kept at the roadside or a charger out on a detached garage. With only 9.2 or 12 kWh to replace, a 3 pin lead gives a proper overnight fill at a friend's house rather than an emergency trickle; its current can be dialled down for older sockets, and the RCD is built into the lead.
Browse every lead for the marque in BMW EV charging cables; the fully electric 7 Series is covered on the BMW i7 charging cable page.
740e, 740Le and 740Le xDrive iPerformance, 2016 to 2019, 9.2 kWh battery
| Cable Type | Max Charge Rate | Empty to Full | Verdict |
|---|---|---|---|
| Type 2 to 3 Pin (5m / 10m) | 2.3 kW | 4h 30m | Genuinely usable on a pack this size |
| Type 2 to Type 2, 16A (5m / 10m) | 3.7 kW | Overnight on any wallbox | Best choice |
| Type 2 to Type 2, 32A (5m / 10m) | 7.4 kW | Overnight on any wallbox | Costs more, no gain |
| Type 2 to Type 2, 32A three phase (5m / 10m) | 22 kW | Overnight on any wallbox | No benefit on this car |
745e, 745Le and 745Le xDrive, 2019 to 2022, 12 kWh battery
| Cable Type | Max Charge Rate | Empty to Full | Verdict |
|---|---|---|---|
| Type 2 to 3 Pin (5m / 10m) | 2.3 kW | 6h 00m | Fine for an overnight away from home |
| Type 2 to Type 2, 16A (5m / 10m) | 3.7 kW | About 3h 20m | Best choice |
| Type 2 to Type 2, 32A (5m / 10m) | 7.4 kW | About 3h 20m | The car sets the pace, not the cable |
| Type 2 to Type 2, 32A three phase (5m / 10m) | 22 kW | About 3h 20m | No benefit on this car |
We pride ourselves on the quality of our cables. Every cable comes with a 2 year manufacturer's warranty, and the jacket will survive being driven over, though we would rather you did not make a habit of it.
Protection against pressure
Our cables are safe to use whatever the weather. Type 2 to Type 2 cables are IP55 rated, CE marked, and work from -30°C to +50°C. Type 2 to 3 pin cables are IP67 rated, CE marked and work from -30°C to +60°C.
Protection against temperature
Our cables fit any electric car or plug-in hybrid with a Type 2 inlet, including Audi, BMW, Volvo, Mini, Mercedes, Kia, Hyundai, Volkswagen, Smart and Toyota. Use our car reg checker to confirm your car.
Compatible with all Type 2 cars
A Type 2 to Type 2 cable, and 16A is plenty. The 740e carries a 9.2 kWh battery and the later 745e carries 12 kWh, both small enough that a 3.7 kW cable empties the job overnight. The same cable fits every 7 Series plug-in hybrid built from 2016 to 2022.
No. The 745e refills in roughly 3 hours 20 minutes on a 7 kW wallbox, which is far less than a 32A cable can carry, so the onboard charger is the limit rather than the lead. Paying for 32A buys you a heavier cable and the same finish time on both cars.
About 3 hours 20 minutes from empty on a 7 kW wallbox for the 12 kWh pack. On a Type 2 to 3 Pin cable at 2.3 kW it stretches to around 6 hours. The earlier 9.2 kWh 740e needs about 4 hours 30 minutes on 3 pin and finishes overnight on any wallbox.
Model years and battery size. The 740e, 740Le and 740Le xDrive iPerformance ran from 2016 to 2019 with 9.2 kWh. The 745e, 745Le and 745Le xDrive took over from 2019 to 2022 with 12 kWh. Both use a Type 2 inlet, so one cable serves both and only the charge time changes.
No. The 730d, 740d, 740i and 750i have no battery pack and no charging port, so nothing on this page fits them. Only the 740e and 745e badges plug in. If you are after the all electric 7 Series, that is the i7 and it has its own page on our site.
Five metres is enough when the wallbox is on the same side as the car and within a couple of paces. Ten metres suits a long driveway, a car parked nose out, or public posts where you cannot choose your bay. A 7 Series boot swallows either length without complaint.

Use our car reg compatibility checker to make sure your getting the right charger for you vehicle.
Cable Type:
How do I Choose?The cable connection depends on what connection type your car accepts. If you don't know, use our handy car reg checker.
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.
