Electric Car Etiquette

[Quiksilver]

At a time when we're being urged, forced even, to reduce electricity consumption and the Government is allowing suppliers to play fast and loose with the contractual terms and conditions of consumers, it totally escapes me why anyone would make themselves reliant (ha!) on a mode of transport that depends on electricity!

Not forgetting that here in CH and in Germany they may be "banned" if electricity is in short supply.

And then there is the issue of vehicle-to-grid - where your car battery can be remotely drained and used to put power back into the grid. It will be a bummer if the day before you pay for a supercharge only to try to use the car the following morning to find you have a flat battery after a windless night.

@ DaveW, from a friendly forum member: a chain is no stronger than its weakest link.

1/ Your puissance souscrite should have enough headroom to feed the iron horse and at the same time enough power for the humans inside the house. Count your blessings:



2/ In single-phase the standard power to charge a car battery is a max of 3.7 kW (about 16 A / 230 V). Advice: currents greater than 8 or 10 amps should be avoided when charging with the help of a regular 16 A socket. These domestic sockets have not been designed for 24/7 max currents. A better solution: make it a circuit specialisé and use a special heavy duty socket + its own interrupteur différentiel + disjoncteur.

3/ More about sockets by the EDF and an introduction to charging modes by Promotelec.

4/ @ Niemeyjt, 22 kW of charging power is a special case. Only for those who have a triphasé connection to the grid ready for the necessary power. If there is a disjoncteur de branchement triphasé of the 30 - 60 A type (for the 18 kVA to 36 kVA clients) it is possible. The other one, from 10 to 30 amps per phase, only for the lower charging powers in three-phase. About the smartmeter LINKY, master of your puissance souscrite with its overload and short protection, this information. The Wallbox chargers allow you to set the maximum power also to 11 kW or lower (US info).

Another problem I see with that is that battery life (that is life before it has to be replaced) is reduced in proportion to the number of charge/discharge cycles.
So selling power from your very expensive car battery means it will need replacing sooner.
If drawing power from it becomes a regular occurrence, much sooner.

BTW, how many people check the battery replacement cost before buying an electric car?
I have seen complaints on forums from people who have found that the new battery they need will cost more than their 4 or 5-year-old car is worth.

I think batteries are going to be the killer in many ways : cost of replacement and disposal of used ones, plus the government is trying to persuade people to change to an electric car whilst upping the cost of electricity ....

I assume that car batteries are not the type that last longer if allowed to run flat before recharging ?

The radios we use at work, which don't seem to have changed in design for donkey's years, don't hold their charge if put on the charger when they've hardly been used.

I wouldn't expect visitors to ask to charge their car in the same way as I wouldn't expect visitors to ask me to give them some diesel or petrol for their car.

[Nomoss]

I don't believe following the herd in rushing into new things is a good thing.
I can see electric cars ending up like 8-track tape recorders, Betamax, and a host of other great innovations.

Add devices such as TOM TOM sat nav ,put one up for sale the other week surprise no takers then realised everybody uses the phone nowadays. Might as well bin it.

Here is a link https://youtu.be/R5XmPti_FeI with some information about the great electric car brainwash. I think its an American politician in some sort of meeting or debate about mining permissions. Food for thought if you think buying an electric car makes any sort of Eco sense.

My concern is that customers demanding electric car charging will push up the price of accommodation in chambres d’hôtes. If plugging in their cars becomes the norm the owners will have to make up the cost somehow. I’ve watched quite a few videos where electric car owners seem to think that it’s a basic right.
Personally although I have petrol flowing through my veins I’d love an electric car but I’m waiting to see if the prices start coming down and I’m worried that if I jump too soon I might miss a vital battery technology upgrade. For now I’m happy to rely on my ageing ICE vehicles but the next car I buy will be electric.
