Audi A3 Sportback TFSI PHEV charging cable

The Audi A3 Sportback TFSI e is a compact plug-in hybrid hatchback that has evolved considerably across its 8Y generation. The pre-facelift model, sold from 2021, paired a 1.4-litre petrol engine with a 13 kWh battery and a 3.6 kW single-phase onboard charger. The 2024 facelift brought a far more capable system: a 25.7 kWh gross battery with 19.7 kWh usable, an 11 kW three-phase AC charger, and, for the first time on an Audi PHEV, 50 kW DC rapid charging. Both generations share the same Type 2 charging port, located on the left front flank.

Charging specs: pre-facelift versus facelift

The pre-facelift A3 Sportback TFSI e (2021–2024) carries a 13 kWh gross battery with approximately 10.4 kWh usable. Its onboard AC charger is rated at 3.6 kW single-phase. WLTP electric range is around 66 km (41 miles), and the 150 PS combined system covers 0–100 km/h in 7.6 seconds. There is no DC charging capability on this version.

The 2024 facelift is a different proposition. The battery grows to 25.7 kWh gross and 19.7 kWh usable, and the onboard AC charger rises to 11 kW three-phase. DC charging is available at up to 50 kW via CCS2. WLTP electric range reaches 142 km (88 miles). Two power variants are available: the 40 TFSI e with 204 PS combined and 0–100 km/h in 7.4 seconds, and the 45 TFSI e with 272 PS combined and 0–100 km/h in 6.3 seconds.

How long does a full charge take

For the pre-facelift model, the 3.6 kW ceiling means a full charge from empty takes approximately 3 hours at any wallbox or public charger. Because the onboard charger is single-phase and capped at 3.6 kW, connecting to a three-phase 11 kW or 22 kW point makes no practical difference: the car draws only what its onboard charger accepts. Most owners simply top up overnight, keeping the battery near full between regular trips.

For the 2024 facelift at 11 kW from a compatible three-phase wallbox or public AC point, a full charge from empty takes around 2 hours. On a standard single-phase home wallbox, the correct cable choice determines the actual charge rate: see the cable section below. On a 50 kW DC rapid charger, the battery reaches 80% from 10% in under 30 minutes.

Which cable do you need

For the pre-facelift A3 TFSI e (2021–2024): the onboard charger tops out at 3.6 kW single-phase. Any Voldt® Type 2 cable rated at 7.4 kW or above works physically, but charging speed is capped by the car regardless of cable rating. An 11 kW cable is the recommended choice for future-proofing across public AC posts. A 22 kW cable is the option for those who want maximum versatility for future vehicles.

For the 2024 facelift: the 11 kW three-phase onboard charger makes an 11 kW Type 2 cable the correct match for three-phase wallboxes and public AC posts. However, on a standard single-phase home wallbox (7.4 kW), an 11 kW three-phase cable will bottleneck the session to 3.7 kW, because its conductors are rated at 16A per phase rather than the 32A a single-phase wallbox delivers on one line. To reach the full 7.4 kW from a single-phase supply, a dedicated 7.4 kW single-phase cable or a 22 kW three-phase cable is required. If your home wallbox is three-phase, an 11 kW cable is the straightforward choice. If it is single-phase, a 22 kW cable covers both home and public use without compromise.

Cable length: what works in practice

For home use with a fixed wallbox, a 5 or 6-metre cable covers the majority of driveway and garage configurations comfortably. The charging port sits on the left front flank, so parking orientation is worth considering before settling on a length. For public charging, an 8-metre cable gives considerably more flexibility, removing the risk of falling short at an awkwardly positioned post.

Portable charging with a CEE charger

The Voldt® portable CEE charging cable is a practical addition for both generations, particularly for travel or locations without a fixed wallbox.

For the pre-facelift (3.6 kW AC ceiling): the car's single-phase limit applies across all socket types. On a 16A single-phase CEE socket (3.7 kW), a full charge from empty takes approximately 3 hours. Connecting to a 16A three-phase or 32A three-phase CEE socket does not increase speed: the onboard charger draws only from a single phase and is capped at 3.6 kW regardless of what the socket makes available.

For the 2024 facelift (11 kW AC ceiling): socket type makes a genuine difference. On a 16A single-phase CEE socket (3.7 kW), a full charge from empty takes approximately five and a half hours. On a 16A three-phase CEE socket (11 kW), the car charges at its full AC capacity, completing a charge in around 2 hours. On a 32A three-phase CEE socket (22 kW), the car is again capped at 11 kW: charge time is the same as the 16A three-phase option.

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. For the pre-facelift that means around 3 hours for a full charge; for the facelift around five and a half hours. Both are workable for an overnight stop, with the facelift benefiting meaningfully from any three-phase supply that is available.
