Audi S6 E-Tron Charging cable

The Audi SQ6 e-tron and SQ6 Sportback e-tron are fully electric performance SUVs sharing identical powertrain and charging hardware across two body styles. The SQ6 e-tron is the traditional upright SUV; the SQ6 Sportback e-tron adds a sloping coupé roofline and a fractionally longer WLTP range. Both are dual-motor quattro all-wheel-drive models producing 360 kW (489 PS) in standard operation and 380 kW (517 PS) with boost, with 855 Nm of torque and 0–100 km/h in 4.3 seconds. The 100 kWh gross battery (94.9 kWh usable) operates on an 800-volt architecture, supporting up to 270 kW DC rapid charging and 11 kW AC charging as standard, with a 22 kW AC option available. WLTP range is up to 598 km (372 miles) for the SUV and up to 607 km (377 miles) for the Sportback. Like the Q6 e-tron, both models carry charging ports on both rear flanks: the combined CCS/Type 2 inlet on the left rear handles both DC and AC charging, while a second AC-only Type 2 port on the right rear provides flexibility when the primary port side faces away from a charge post.

Battery and charging architecture

The 800-volt electrical system is the defining feature of the SQ6 e-tron's charging capability. At a compatible 800V DC rapid charger, the battery charges at up to 270 kW and covers the 10–80% window in approximately 21 minutes. Ten minutes of charging under ideal conditions adds up to 255 km (158 miles) of range. At 400V DC chargers, the SQ6 e-tron uses bank charging: the battery splits into two equal halves that charge in parallel, delivering up to 135 kW combined without requiring an 800V supply. The AC onboard charger is 11 kW three-phase as standard, with 22 kW three-phase available as a factory option.

AC charging at home and at public wallboxes

With the standard 11 kW three-phase onboard charger, a full charge from empty takes approximately ten and a quarter hours at a compatible three-phase wallbox. In practice, most SQ6 e-tron drivers charge overnight from a partial state rather than from empty. With the optional 22 kW three-phase charger, a full charge from empty drops to approximately five hours at a 22 kW three-phase supply.

Choosing the right cable

Both Type 2 inlets accept a Voldt® Type 2 charging cable. For the standard 11 kW onboard charger, an 11 kW cable is the correct match at any three-phase wallbox or public AC post. For cars fitted with the optional 22 kW charger, a 22 kW cable is required to unlock the full charging rate: an 11 kW cable would cap a 22 kW session at 11 kW.

On a single-phase home wallbox (7.4 kW), an 11 kW three-phase cable bottlenecks the session to 3.7 kW, as its conductors are rated at 16A per phase rather than the 32A a single-phase wallbox delivers on one line. At 3.7 kW, a full charge on the 94.9 kWh battery takes around 28 hours. A 22 kW cable, whose conductors are rated at 32A per phase, carries the full single-phase load and delivers 7.4 kW, reducing that to approximately 15 hours. For owners with a single-phase home installation, a 22 kW cable is the practical choice regardless of which onboard charger is fitted.

Cable length

The left-rear combined port suits reverse-entry bays and aligns with the nearside in UK parallel parking layouts. The right-rear AC-only port is useful for nose-in approaches and off-street bays where the post is on the passenger side. A 6-metre cable suits most home driveway and garage configurations. An 8-metre cable covers the wider variation in bay layouts and post positions found at public charging stations. For locations with greater distances between post and parking space, 10 and 15-metre options are also 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 complements the SQ6 e-tron's DC capability with flexible AC charging wherever a fixed wallbox is not available. Given the large 94.9 kWh battery, socket choice has a meaningful impact on charge time. On a 16A three-phase CEE socket (11 kW), a full charge takes approximately ten and a quarter hours, well suited to an overnight stay. On a 32A three-phase CEE socket (22 kW), cars with the standard 11 kW charger see the same result; cars with the optional 22 kW charger complete a full charge in approximately five hours.

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. At that rate, a full charge from near-empty takes around 28 hours, making a campsite blue socket suitable for a partial top-up during a multi-night stay but not a realistic source for a full charge. On a standard domestic socket at 2.3 kW, a full charge would take around 41 to 45 hours: relevant only as an emergency top-up option, not a practical charging method for a battery of this size.
