Audi A7 Sportback TFSI PHEV charging cable

The Audi A7 Sportback TFSI e quattro is a large four-door liftback plug-in hybrid combining a sleek coupé-inspired roofline with a practical hatchback boot. It is available in two power levels: the 50 TFSI e with 220 kW (299 PS) combined output and 0–100 km/h in 6.3 seconds, and the 55 TFSI e with 270 kW (376 PS) and 0–100 km/h in 5.6 seconds. Both share the same 2.0-litre TFSI petrol engine, gearbox-integrated electric motor, quattro all-wheel drive, and identical charging hardware. Battery is 17.9 kWh gross and 14.4 kWh usable, with a 7.4 kW single-phase onboard AC charger and no DC rapid charging. WLTP electric range is up to 67 km (42 miles). The Type 2 charging port is located on the left rear flank.

Battery, range, and powertrain

The lithium-ion battery sits under the luggage compartment floor and provides 14.4 kWh of usable capacity. Audi's predictive drive management uses navigation data to plan battery usage across the route, prioritising electric running in urban zones and reserving charge where it is most effective. Electric-only driving is available at speeds up to 135 km/h (83 mph), covering most everyday running without engaging the petrol engine. Both the 50 and 55 TFSI e variants charge at the same rate, so everything below applies equally across the range.

Charging at home and at public wallboxes

The 7.4 kW single-phase onboard charger draws 32A on a single phase. At any wallbox or public AC point that delivers 32A on a single line, the car charges at its full 7.4 kW rate, completing a full charge from empty in approximately two and a half hours. Connecting to an 11 kW or 22 kW three-phase wallbox does not increase speed: the onboard charger draws from a single phase only and is capped at 7.4 kW regardless of what the wallbox delivers. A 50% top-up at 7.4 kW takes around 75 minutes, which suits most daily charging patterns without needing a full cycle.

Which cable suits the A7 Sportback TFSI e

The 7.4 kW single-phase onboard charger requires 32A on a single line to reach its full rate. An 11 kW three-phase cable is not the correct match: its conductors are rated at 16A per phase, and on a single-phase supply it delivers only 16A × 230V = 3.7 kW, halving the charge rate and doubling the session time. To reach the full 7.4 kW, the correct choice is a Voldt® 7.4 kW single-phase cable or a 22 kW three-phase cable, whose 32A-per-phase conductors carry the full single-phase load without restriction. A 22 kW cable is also the forward-looking choice for drivers planning ahead for a future vehicle with 11 kW or 22 kW three-phase charging, requiring no change of hardware when moving on.

Cable length

The charging port sits on the left rear flank, making reversing to the wallbox the most practical approach at home. A 6-metre cable covers the majority of home driveway and garage configurations comfortably. An 8-metre cable is the sensible choice for public charging, where bay layouts and post positions vary widely between stations. For locations with greater distances between post and bay, 10 and 15-metre cables are available. For dedicated commercial or specialist installations, Voldt® supplies cables up to 40 metres.

Portable charging with a CEE charger

The Voldt® portable CEE charging cable makes the A7 Sportback TFSI e straightforward to charge wherever a fixed wallbox is unavailable. On a 16A single-phase CEE socket (3.7 kW), a full charge from empty takes approximately four hours. On a 16A three-phase CEE socket, the single-phase onboard charger draws from one phase only, receiving 16A at 230V = 3.7 kW: the same four-hour charge time as the single-phase socket. On a 32A three-phase CEE socket, one phase carries 32A at 230V = 7.4 kW, completing a full charge in approximately two and a half hours, matching the speed of a dedicated wallbox. On a standard domestic socket at 2.3 kW, a full charge takes around seven hours, a practical overnight option for this battery size.

Red three-phase CEE sockets are found at industrial sites, workshops, and some commercial marinas. Standard European campsite hookup points use blue single-phase 16A CEE sockets, which cap output at 3.7 kW and result in the four-hour charge time noted above. For a 14.4 kWh battery, a campsite overnight stop is entirely practical at this rate.
