EV (Electric Vehicle) Get Me Home Charging on 13A sockets

Owners of certain electric cars will likely to have a “Get Me Home” cable which can be plugged into a standard domestic 13A socket.  Useful if visiting friends or relatives and you have misjudged the power in the car batteries needed to get you home.

Take a little care with these charging cables because they often need a fairly continuous 10A of electricity while plugged in.  A 13A socket is designed to provide 10A of electricity but be aware this socket could be on the primary downstairs sockets circuits of a home which is designed for 32A maximum.  Where this same circuit could have high energy use tumble drier, washing machine, portable heaters or similar. Maybe in a busy home with guests present so more occupants than usual as well.  So suggest apply some common sense  to enquire as what you are planning to plug a Get Me Home Lead into.

Also if the property at which this lead is being plugged in happens to be an old small terraced house or flat that has not been renovated of late, be aware there are still quite proportion of old electrical services that are rated at 60A maximum for the whole house, and old Consumer Units (Fuse Boxes) with a maximum limit of 60A for the whole house. More modern installations will have 100A capacity for a whole house.

Electric Vehicle Charging Point

In Residential use if you want to avoid the ugliness and hassle of having that power lead trailing from your under the garage door or out of a window to your Electrical Vehicle, then how about installing a proper EV charging point.  If you are starting out and have a requirement for only a 16A (3.6Kw) powered point then I would seriously consider installing a 32A (7.2Kw) capable circuit. One reason being is the extra costs for a larger 32A cable and protection accessories are relatively small compared to the overall installation labour cost to run a cable from the home Consumer Unit (Fuse Box) through the house to a charging point.  Also your next vehicle or a change of use might benefit considerably with a 32A powered point so an upgrade would be less disruptive on the house and cheaper.

If you are thinking about the Tethered or Non Tethered choice, then certainly Tethered is convenient.  No wet grubby cable to tidy up and keep in the boot. But if you change vehicles often or have guests to stay with other types of vehicles to charge, then Un Tethered has its benefits.

Some designs of Charging Points have an outside grade 13A socket built in as well. Useful for vacuuming the car or powering that lawnmower.
