Does the Tesla Wall Connector Have PEN Fault Protection? (UK)
Why UK EV charge points on PME supplies need protection against an open PEN fault, the options installers use, and how to check any charger, including Tesla’s.

Why UK EV charge points on PME supplies need protection against an open PEN fault, the options installers use, and how to check any charger, including Tesla’s.

You do not need a special charger to start: every EV can use a standard outlet with a Level 1 cable. Here is when a Level 2 charger, an adapter or a specific connector matters.

J1772 is the SAE standard AC charging connector used by most non-Tesla EVs in North America. Why it is called J1772, which cars use it and how it relates to CCS and NACS.

Yes. Teslas charge at J1772 Level 2 stations with a J1772-to-NACS adapter. Where to get one and what speed to expect.

A CCS1 car inlet accepts a J1772 plug for AC charging because CCS1 is J1772 plus two DC pins. What CCS is and how it differs from CHAdeMO and NACS.

Certified adapters rated for the charging current and approved by your automaker are safe. What to check, which adapters to avoid and why DC adapters need extra care.

Some EVs include a Level 1 cord or a Type 2 cable; many no longer do. What to check at delivery and what to buy if it is missing.

DC fast chargers deliver 50 to 350 kW. The DOT estimates 180 to 240 miles of range per hour of charging; most cars go from 10% to 80% in roughly 20 to 45 minutes.

DC fast chargers convert grid AC to DC inside the station and feed the battery directly, under the car’s control. The power path, the communication and the cooling.

A first-timer’s guide to DC fast charging: plan, precondition, plug in, pay, monitor and leave promptly.
