ABB Terra AC W9-P8-R-D

ABB Terra AC W9-P8-R-D is a Level 2 home EV charger from ABB with up to 40 A (9.6 kW) output and a J1772 connector — 26 ft cable, networked smart charging.

Our take

Cable reach is the differentiator: 26 ft is longer than 98% of the 56 certified 40 A models in this database, two feet past the cohort median and enough to serve either bay of a wide garage without repositioning the car. The rest is a straight ABB Terra AC package — 9.6 kW on a 50 A circuit, about 34 miles of range per hour, Wi-Fi connectivity, and full-rate compatibility with 25 of our 29 tracked EVs. Standby draw of 2.76 W runs modestly above the 2.38 W class median, a difference of a few kWh a year.

Best for: Installs where an extra couple of feet of cable decides where the unit can mount.
Trade-off: Idle draw is slightly above the class median, though the cost difference is trivial.

EV compatibility

The ABB Terra AC W9-P8-R-D's J1772 connector plugs directly into 23 of the 29 EVs tracked in this database. The other 6 (Hyundai Ioniq 5, Tesla Cybertruck, Tesla Model 3, Tesla Model S, Tesla Model X, Tesla Model Y) work with it too — requires a J1772-to-NACS adapter (Tesla includes one with its vehicles).
