Well, on a 3kw fan heater on for two hours the plug even on a brand new
socket can be warm. I guess it depends what margin of safety you prefer, and of course how well the socket and plug are fitted to the bare wires and how warm the fuse inside is allowed to be without blowing, not to mention the resistance of the dissimilar metals used in their construction these days. For example, just cos a 6 way socket bar has a 13 amp fuse taking the whole drain through one of its sockets makes it get quite warm, as they are in effect supposed to be a shared load. I was led to believe that many Electric vehicles can have the charging current varied and of course the lower the charge rate the longer it will take. A large cooker point might be nearer what is needed here I imagine. Brian -- ----- -- This newsgroup posting comes to you directly from... The Sofa of Brian Gaff...

I vaguely recall that the HV battery in my car operates at 130V, but I can't find the info to confirm that. |

If it's okay after 60 minutes, is it not likely still to be okay after 10 hours? At 13A for 1 hour a UK socket gets really rather hot. The sort of thing that can happen when you have a 3kW fan heater in a very cold room. I have seen moulded extension blocks melt or deform under such loads. I've seen a lot of worrying things after having electric heaters plugged in for long periods at work. It's presumably why it's one of the questions our insurer asks, 'do you use portable heating?' Probably more a case of fire risk if a heater is knocked over or has something put in front or even on it. Sockets can get fairly warm with no risk of overheating. SteveW |

A standard plug and socket can carry 13A - but there are provisos. It needs to be well terminated, and the pins etc need to be very clean. It will also still get hot (you will gets several watts of dissipation in the fuse for example). So its not the ideal connection for long term heave loads near the maximum. I discovered that after putting MK plugs and sockets into a mate's "light industrial" application with 3 kW immersion heaters running typically for up to 12 hours. (Having plugs and sockets added flexibility when elements or controllers failed). Since going over to the standard 16A industrial plug and socket (no switch or fuse) there have been no problems at all. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

It depends on the charger. My Outlander came with a ‘free’ (supplied by Mitsubishi) charger which you can use with a normal 13A socket- as I do almost every time it needs charging. It takes about 5 hrs or so. (The car has a timer so I set it to use economy 7 over night.) The Gov. also paid for a “ quick “ charger to be fitted to my house- it has a dedicated 16A spur etc. It charges in about 3 hrs. I use it when needed. I have run the ‘slow ‘ one during the day and checked the socket. It didn’t get noticeably warm. Would it not be possible to wire the quick charger to Economy 7 and use the slow charger at other times only when needed? Yes. For various reasons, I opted to have the quick changer outside. As I normally park the car in the garage, I use the slow charger. The timer is a function of the car system, so it will work with either charger. I could have had the quick charger in the garage but it seemed a good idea to have it outside, in case we bought another car and wanted to put that in the garage or a visitor needed to use a charger on the drive. |

My Mitsubishi draws 10 amps on charge. I have had the car for six years, no problems. Typical charging times between two and four hours. Plugged into 13A socket on ring main. And how many miles does that give you running on electric power? Well 4 hours at 10 A at 230 V is 9.2 kWhr. A gallon of diesel contains over 10 kWhr... -- Cheers Dave. |
