Using a 16A Schuko socket
So, I have an EV (Leaf) which would benefit from the ability to charge
using more than a 13Amp socket can supply. The supplied charging unit/cable limits to about 10A, but the car's on board charger can accept up to 3.3kW (some say 3.6kW). This would need a different EVSE than the supplied unit, AND a beefier mains socket. Is it OK, in terms of building regs etc, to have a Schuko 16A socket on a radial from the CU? I know I can get a proper home charge point installed, but that's not the cheapest option. TIA. |

Charge points contain a protocol controller to handle comms with the car and to enable a contactor once safe so to do, they also have an RCD. Finally, they're supposed to be TT'd to ensure that supply and car ground potentials are similar. It's probably cheaper to buy a charge point (currently about £135 on fleabay) than building one yourself. |

Not many caravans can take 43kW Can't see why the car has to talk to the supply point AFAIK there's not much signalling from car-EVSE just a resistor divider to let the car say it's connected and ready, or it's charging, or there's an error. Also a diode so the EVSE can't be fooled by a short on the signalling pin. Signalling from EVSE-car is a 1kHz tone, where the duty ratio says how many amps it's able to provide. |

Pretty sure the IET regs have a prohibition on unshuttered sockets in a domestic setting. Commando with an interlocked isolator would technically be a departure but at least trivial to justify. That's my understanding anyway - could be wrong and welcome correction. |

Commando with an interlocked isolator would technically be a departure but at least trivial to justify. There is a commando where the isolation is included in the socket - such that you can't energise it until the plug is in.

Some of the newer sites have outlets on the bollards which require you to twist the plug after inserting it and to press a button to release it. They confuse overseas visitors and those whove not seen them before - they try another socket, then start asking €˜neighbours if their power works etc. |

Using a 16A Schuko socket
As long as the cable does not cross a footway and remains in your own
premises, ie if you have a garage or hard standing, I'd imagine you can use what you like. Obviously it has to be safe for visitors etc, ie coming out of a window and snaking across in front of the door might be an issue if the postman breaks his leg and sues!

Is it OK, in terms of building regs etc, to have a Schuko 16A socket on a radial from the CU? I know I can get a proper home charge point installed, but that's not the cheapest option. The schuko straight off the CU, by itself wouldn't give you proper earthing for an EV. |

The charge lead will often include the type A RCD. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

So, I have an EV (Leaf) which would benefit from the ability to charge using more than a 13Amp socket can supply. The supplied charging unit/cable limits to about 10A, but the car's on board charger can accept up to 3.3kW (some say 3.6kW). This would need a different EVSE than the supplied unit, AND a beefier mains socket. Is it OK, in terms of building regs etc, to have a Schuko 16A socket on a radial from the CU?

Thanks for the link. Would it not make more sense to hard wire in a proper 32A style charger? Yes, but... The car is a company car and as yet they haven't decided if providing me with a home charging point is something they want to pay for. Charging at work is provided - free. The car only has a 3.3kW on-board charger (excluding the quick charge option) for connection to 230Vac. The supplied EVSE charge cable is limited to 10Amps, 2.2-2.4kW. But if I get a 16Amp EVSE, then that could be considered as an accessory for the car, and the company would then pay. Only £100-£150. And I don't mind stumping up a few pounds for a Schuko in the garage. |
