BMW 740E eDrive charging cable

The BMW 740e iPerformance was the first plug-in hybrid in the G11 7 Series lineup, produced from 2016 until the 745e replaced it with the 2019 facelift. Its powertrain combines a 2.0-litre turbocharged four-cylinder (190 kW) with an 83 kW electric motor integrated into the eight-speed Steptronic gearbox, producing a combined 240 kW and 500 Nm. The standard 740e is rear-wheel drive and reaches 62 mph in 5.4 seconds, while the long-wheelbase 740Le completes the sprint in 5.5 seconds. The 740Le xDrive adds all-wheel drive across the same powertrain. A 9.2 kWh battery (7.4 kWh usable) provides 27 to 30 miles of NEDC electric range in the shorter-wheelbase car, with the xDrive returning 25 to 28 miles. Real-world figures on a typical commute sit noticeably below those NEDC numbers. No DC rapid charging is available on any variant. The onboard AC charger operates at 3.7 kW (single-phase, 16A), and the Type 2 charging port is located on the left front wing. The 740e is now found almost exclusively on the used market, but its charging requirements remain straightforward and fully supported by current Type 2 infrastructure.

Which cable suits the BMW 740e?

Every 740e variant charges through a Type 2 connector. The onboard charger accepts a maximum of 3.7 kW at 16A on a single phase, so the cable rating makes no difference to charging speed: an 11 kW Voldt® Type 2 cable delivers the full 3.7 kW, and a higher-rated cable does exactly the same. The car's charger is the limiting factor, not the cable. For the 740e on its own, the 11 kW cable is the correct choice. A 22 kW cable performs identically on this car and becomes worthwhile only if you share it with a vehicle that charges faster, or if you intend to keep the cable for a future fully electric car. Since the 740e is now a used-market car, many owners already have or are planning a second vehicle with a more capable charger, which makes the 22 kW cable a practical investment beyond the 740e itself.

The charging port sits on the left front wing, so pulling forward into a bay puts the connector on the correct side for most wallboxes and public posts. A 6-metre cable covers the majority of home installations. An 8-metre cable is the better long-term option if you charge at varied locations or use public posts where the distance from pillar to port can be less predictable.

Charging on the move

With only 7.4 kWh of usable capacity, the 740e's battery is small enough that portable charging covers a full cycle in a remarkably short window. The Voldt® blue CEE portable charger delivers 3.7 kW from a 16A single-phase industrial socket, the full rate the onboard charger can accept. Approximately two and a half hours from near-empty fills the battery completely, so any campsite, marina, or workshop with a blue CEE socket becomes a genuinely useful charging stop rather than a compromise. For a car designed around relaxed long-distance travel, the blue CEE charger fits naturally into a lunch break or an afternoon pause.

The Voldt® three-pin portable charger connects to a standard UK household socket and delivers up to 2.8 kW (13A), within the limits of what your household wiring can sustain. A built-in thermal sensor tracks the connection temperature continuously and adjusts the current automatically if the socket or cabling runs warm. At 2.8 kW, the 740e's battery fills from near-empty in approximately three hours: comfortably within an evening at home, an afternoon visit, or an overnight stop anywhere with a standard socket. A battery this size turns the three-pin charger into something closer to a primary charging tool than a fallback. Plug in when you arrive, leave with a full battery, no wallbox required.
