Audi A3 TFSI e 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 modest 3.6 kW onboard charger. The 2024 facelift brought a far more capable system: a 25.7 kWh gross battery, an 11 kW three-phase AC charger, and, for the first time on an Audi PHEV, 50 kW DC rapid charging. Both share the same Type 2 charging port, located on the left front flank of the vehicle.

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 41 miles, and the 150 PS combined powertrain covers 0–62 mph 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 the CCS2 port that supplements the Type 2 socket. WLTP electric range reaches 88 miles. Two power variants are available: the 40 TFSI e with 204 PS combined and 0–62 mph in 7.4 seconds, and the 45 TFSI e with 272 PS combined and 0–62 mph 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 2 hours 50 minutes at any wallbox or public charger. Because the onboard charger is single-phase, connecting to a three-phase 11 kW or 22 kW point makes no practical difference: the car draws only what its onboard charger accepts, which is 3.6 kW. Most owners simply top up overnight, keeping the battery near full between regular trips.

For the 2024 facelift, the 11 kW three-phase charger allows a full charge from empty in around 2 hours at a compatible three-phase wallbox or public AC point. A single-phase 7.4 kW wallbox will charge the 19.7 kWh usable pack in approximately 2 hours 40 minutes. On a 50 kW DC rapid charger, the battery can reach 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 Type 2 cable rated at 7.4 kW or above will work physically, but charging speed is capped by the car, not the cable. An 11 kW Type 2 cable is the recommended choice: it matches every public AC point and home wallbox you will encounter and leaves room for a more capable vehicle in future. A 22 kW cable is an option for those who want complete future-proofing, though the current car will never exceed 3.6 kW regardless.

For the 2024 facelift: the 11 kW three-phase onboard charger makes an 11 kW Type 2 cable the correct match for everyday home and public AC charging. If you plan ahead for a future vehicle with 22 kW AC charging capability, a 22 kW cable is a reasonable upgrade: it is fully compatible with the A3 facelift and future-proofs your investment in one purchase.

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 far more flexibility. Charging bay layouts and post positions vary considerably, and the additional length removes the risk of the cable falling short at an awkwardly positioned station.

Portable charging with a CEE charger

A portable CEE charger is a practical addition for both generations of the A3 TFSI e, particularly for travel, away-from-home stops, or locations without a fixed wallbox.

Pre-facelift (3.6 kW AC ceiling):

The car's 3.6 kW single-phase limit applies across all socket types. A 16A single-phase CEE socket delivers 3.7 kW, meaning a full charge from empty takes approximately 2 hours 50 minutes. Connecting to a 16A three-phase or 32A three-phase CEE socket does not increase speed: the car's onboard charger draws only from a single phase and is capped at 3.6 kW regardless of what the socket makes available. Charge times remain the same.

2024 facelift (11 kW AC ceiling):

Here, socket type makes a genuine difference. On a 16A single-phase CEE socket (3.7 kW), a full charge from empty takes approximately 5 hours 20 minutes. 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 output available), the car is again capped at 11 kW, so charge time is the same as the 16A three-phase option: around 2 hours.
