An 11kW EV charging cable runs at 16A three-phase — the middle option between 7.4kW (single-phase) and 22kW (full three-phase). It's the right answer for UK three-phase homes paired with an EV that accepts 11kW AC but not 22kW — which is most of them, including BMW, VW Group, Mercedes, Tesla and Polestar.
When 11kW is the right choice
Two conditions need to be met:
- Three-phase supply at your property — most UK homes are single-phase. Confirm with a qualified electrician.
- Your EV accepts 11kW AC — most modern EVs do. The list of 11kW-only cars (won't take 22kW) is long: BMW i3 refresh, i4, i5, i7, iX1, iX3, iX; VW ID.3, ID.4, ID.5, ID.7; Audi Q4 e-tron, Q6 e-tron; Mercedes EQA, EQB, EQE, EQS; Tesla Model 3, Model Y; Polestar 2, 3, 4; Volvo EX30, XC40 Recharge; Hyundai Ioniq 5, 6; Kia EV6, EV9; Nissan Leaf Mk3.
If condition 1 isn't met, you don't need 11kW — go with 7.4kW single-phase. If condition 2 isn't met (your car accepts 22kW), step up to 22kW.
What 11kW means for charge speed
At 11kW three-phase you add ~45 miles of range per hour, vs 25-30 at 7kW single-phase. A 60kWh battery refills 10-100% in about 5 hours, vs 8 hours on single-phase. For typical UK commuter use (50-mile daily mileage), the difference is small — both refill comfortably overnight. For high-mileage drivers (taxi, sales, fleet) the 1.5-3 hour saving each charge cycle adds up materially.
Connector type
Type 2 (Mennekes) — same connector at both ends as 7kW and 22kW. The cable wires up all three phase pins; on a single-phase wallbox it'll throttle to 7.4kW automatically.
Cable build vs 7kW
11kW cables use the same conductor cross-section as 22kW (typically 4mm² per phase) because the current-carrying capacity per phase is 16A — same as a single-phase 16A circuit. The cable is heavier than a 7kW single-phase cable but lighter than a full 32A 22kW three-phase cable.
Length considerations
Three-phase cables are heavier per metre. Pick the shortest cable that works for your driveway:
- 5m — wallbox close to parking spot. Easy to coil.
- 7.5m or 10m — typical UK three-phase driveway with the wallbox on the garage wall.
- 15-20m — long driveways or shared. Note 15m three-phase cables are 8-10kg.
Build quality
- IEC 62196-2 compliance on the connector.
- IP55 minimum on couplings — IP66 if you'll leave plugged in during storms.
- Halogen-free woven jacket — survives UK weather 5-10× longer than rubber.
- 3-year minimum manufacturer warranty; 5 years on premium options.
Pairing with the right wallbox
- MyEnergi Zappi 22kW — three-phase, native solar diversion. Ideal for UK three-phase solar homes.
- Easee One 22kW — load-balancing across multi-EV setups.
- Wallbox Pulsar Plus 22kW — Power Boost dynamic load management.
- Project EV Pro Earth 22kW — best-value three-phase option at £799.
Three-phase upgrade — when worth it
Upgrading from single-phase to three-phase costs £3,000-8,000 typically, takes 6-16 weeks, and may not be possible everywhere (LV grid capacity constrained in some areas). Worth it if you also run heat pumps, electric AGAs, induction hobs and batteries that benefit from three-phase distribution. Not worth it solely for EV charging — the 1-2 hour overnight saving doesn't justify the capex on a single 7kW vs 11kW comparison.
What it won't do
Won't speed up a single-phase wallbox — supply caps the speed. Won't charge from public DC rapid (CCS) — those are tethered to the rapid post. Won't make a 22kW-capable EV charge faster than 11kW unless your wallbox is also 22kW.
