Why do EVs not use the full 3.12kW from a mains socket?...

In the UK, \"most vehicle manufacturers limit the current drawn from a standard domestic 3 pin socket to 10A or less, which equates to a maximum of 2.3kW.\"

Why? A UK socket is 13A, or 3.12kW.

ROFL! \"The typical cost of a home charge point is around £800.\"

Er.... £100 2nd hand on Ebay plus a bit of cable to connect it to the fusebox. Not £800.

I\'ll play the stright cow here. In the USofA, a \"continous load\"
on a circuit is generall maxed at at _80 percent_ of the rated
wire/circuit carrying capcity.

Reason: heat buildup.

I suspect, with no foundationwhatsever, the UK uses

That\'s about the right, a derating to 80%. The socket may be rated for that current, but the connecting wiring may not be able to handle the temperature rise. It saves the homeowner the cost of a new circuit installation, which for most people equates to hiring an electrician and obtaining a permit.

I\'m no expert in UK electrical regulations, but in other conversations, I\'m pretty sure I\'ve been told this is not the case. The reason is, in the UK, most homes are wired with a \"ring\" that can carry much more than 13 amps. So the wires and breaker are rated at higher currents. So each 13 amp load can actually draw 13 amps.

Also, in the UK, the protection device for everything plugged into an outlet, is in the device. They put a \"fuse\" in the connector itself.

Sounds pretty good to me. In conversations with brits who know about this stuff, they claim their electrical safety is much better than in the US. They don\'t seem to have a problem with tossing out the old every few decades, when they come up with something that is significantly better.

It does not, we wire things properly as we\'re a 1st world country. You can buy 3kW fanheaters for example. I\'ve run one for several hours without anything bursting into flames.

We also have switches on our sockets, and sleeved pins. I guess that\'s why you still have the wimpy 120V in most circuits.

I have an old British plug here, fused. I just opened it for a check,
and the fuse is rated 13A.

With a continuous load of 13A, that fuse will blow. I don\'t know if in
hours, or days, or minutes, but it will blow.

I don\'t think that\'s right. A 13A fuse should not blow at 13A, but may
blow above 13A. It may take some time.

Why above, but not at 13A? These things are not hugely precise. I know you can\'t count on a 13A fuse to blow at 14A. I would not expect to draw 13A from a 13A circuit and never have problems. I guess if you go through a few 13A fuses, you will eventually find a 13.5A fuse and life will be good.

A UK 13A fuse will actually pass about 20A indefinitely.

Fuses are not precision things. For that you need an electromagnetic
current limiter switch. They simply blow faster the higher the current
is. Given time, they will eventually blow even at half the rated current.

Although they are nominally rated at 13A modern sockets are seldom happy
with anything much beyond 10A as a continuous load. I have seen plenty
of extension sockets destroyed by having a fan heater plugged in.

In a cold room a 3kW fan heater doesn\'t switch it off until the
thermostat is satisfied which can be a few hours by which time the
plastic around the socket has melted.

At full 13A load current for an extended period plugs can also get
uncomfortably hot due to the UK having a mains fuse in them.

Short term 3kW loads are OK like kettles for a few minutes (but even
that is now deprecated all modern kettles are 2.4kW aka 10A).

I suspect that they use less beryllium in the spring contacts than they
did in the old days when nominally 13A sockets were real 13A sockets.

It does not, we wire things properly as we\'re a 1st world country. You can buy 3kW fanheaters for example. I\'ve run one for several hours without anything bursting into flames.

UK adopted the ring circuit for residential wiring as a measure to conserve copper which was expensive and in short supply in the 1940s. It is not better.

We also have switches on our sockets, and sleeved pins. I guess that\'s why you still have the wimpy 120V in most circuits.

Much of UK wiring would not be allowed under the national electric code in the U.S. For one would be this crummy ring circuit idea. U.S requires at least two independently fused/ protected circuits per room, UK puts an entire floor on the ring circuit. U.S. not only allows for, but requires, many more electrical outlets than UK. If they try doing the equivalent number on a ring circuit, they would be begging for nuisance trips. Sounds like the ring circuit method has been abandoned for new construction in UK for quite some time.

UK is not exactly famous for high quality housing of any kind, actually the place is a disaster area.

As usual for you, you don\'t have a hint in hell what you\'re talking about, and you\'re completely wrong.

Of course the ring circuit has more capacity, it\'s nearly powering the whole damned house. So, unless they want to up the fault current tolerance of every single thing they plug into it, and thus increase the cost significantly, they have to be fused at lower current.
