Can we recharge an electric car by plugging into a simple plug
The overwhelming majority of car drivers run less than 50 kilometers a day, and thus a classic socket or a green’up will be enough to find a full battery each morning, as long as they are parked and in charge for around 10 hours.
Electric car: what are the ideal charges and charging sockets at home ?
Between a domestic socket and a dedicated charging station, what must be favored to load at home ? We will examine in this file the different possibilities to allow you to choose with full knowledge of the facts.
The electric car will gradually modify our relation to the automobile, for the better as for the worst. Among what worries the most newcomers in the world of trendy vehicles is of course the recharge, especially at home.
We will therefore recall the fundamentals of the load of a car at home, which must be done and not to make, before taking stock of the different existing solutions to install a plug or a charging station. At the end of this file, you should know more about what is possible to install, and what is most suitable for your situation.
Home recharge, essential comfort
If in thermal vehicle there is no other choice to fill your tank than to visit a service station, by electric car the experience is very different. Indeed, like a smartphone or a laptop, you will recharge your car mainly at home, while it is not used. It is also possible to recharge it on the public highway or parking lots, but that is another subject.
Of course, it takes power: having a dedicated location to park and a power supply that happens there. For those who live in individual house with a garage in particular, it is very easy, but for urban residents in collective housing, it is not necessarily obvious. In the latter case, know that you can invoke the right to take.
With the necessary to recharge at home, ideally the vehicle can be connected every night, and thus have a battery filled or almost, every morning. In this way, the experience of the electric vehicle will even be better on a daily basis than that of a thermal vehicle, in the sense that there will never be necessary to think where and when to recharge: it will be at home, while the we sleep.
In addition to the advantage of not wasting time and always having a vehicle with a full battery, the cost of home recharge will break all records in the face of a petrol vehicle. Indeed, considering the average cost of the kilowatt hour electricity in France at 0.17 euros, and a consumption of an average vehicle of 18 kWh per 100 kilometers, The price to cover 100 kilometers amounts to only three euros.
Opposite, average consumption per 100 kilometers according to ADEME for a petrol vehicle was located at 6.8 liters in 2020, and at the current price of 1.90 euros per liter, it comes up at a price of almost Thirteen euros per 100 kilometers, either more than four times more than the price of an electric vehicle.
If the advantage of recharging at home your electric car should no longer be questioned, it remains to be seen what are the different load solutions that exist, and their particularity.
Domestic or reinforced socket
Many people arriving in the universe of electric mobility are not aware of it, but It is quite possible to load your electric car on a conventional outlet. Indeed, many manufacturers also deliver an occasional charging cable with the purchase of a trendy car (CRO), which allows you to use a domestic outlet.
With this loading method, you will therefore need no additional equipment, which limits the necessary investment, provided that a plug is already available where you park your vehicle (this is for example the case in a garage adjoining a home).
One of the precautions to be taken to avoid any overheating problem linked to recharging is to limit the intensity to 8 or 10 amps (1.8 or 2.3 kW), the classic sockets being planned for 13 amps maximum, but rather For short durations. In the case of a car load which can last more than ten hours without stopping, it is therefore advisable to limit the intensity (either at the level of the electrical panel, either directly from the interface of the vehicle when possible )).
Of experience, on recent installations (in 3G 2.5 mm2), there is no problem to recharge at 13 amps (3 kW) on long periods. This allows, for example, to recharge a model 3 propulsion and its 60 kWh battery in about 20 hours. But beware with aging installations or you don’t know.
In the event that you do not have an outlet nearby and that it should be added, the Green’Up de Legrand socket at around 80 euros is an excellent alternative to a classic socket, since it allows you to load more quickly while remaining compatible with the domestic charging cable provided with the vehicle.
Its advantage is that it allows the load at 3.7 kW (at 16 amps), against between 1.8 and 3 kW with a conventional domestic socket. In practice and to use more digestible units, A Green’UP socket will recover approximately 20 kilometers of autonomy per hour of load, compared to 10 to 13 kilometers on a conventional socket.
The overwhelming majority of car drivers run less than 50 kilometers a day, and thus a classic socket or a green’up will be enough to find a full battery each morning, as long as they are parked and in charge for around 10 hours.
However, to optimize recharges and ensure that they are faster, it will be necessary to consider something other than a domestic socket, as we will see below below.
Industrial socket P17
If the solution consisting in using a domestic socket is acceptable for many, it is far from ideal in many cases. Indeed, in addition to the large rollers to add only 150 kilometers of autonomy each day will not be possible, we can also cite people with an electricity subscription with a preferential rate depending on the hours (EDF tempo option, or off -peak hours) and who therefore want to minimize the costs related to the load.
Similarly, some households today have several electric vehicles, and if there is only one load point, it must be powerful enough for each vehicle to be able to recharge enough to respond to its needs.
Thus, industrial socket P17 (blue) can be a good solution, since it will allow a charge to a power between 3.7 kW and 7.4 kW depending on the installation (between 16 and 32 amps). If you have an electric subscription three -phase, You can even go up up to 22 kW of power with a P17 three -phase (red) 16 Ampères socket.
However, the decree relating to charging infrastructure for electric vehicles does not specify that industrial sockets P17 are authorized to recharge electric vehicles, so it will be necessary to check the compliance of its installation if necessary. A legal installation in other European countries.
If you set up a single -phase P17 16 or 32 amps, you will need to plan Compatible charging cable, or an adapter as Tesla sells it for its mobile connector. The cost of the adapter being only 48 euros to date is a good economical solution to be able to load at a power of 7.4 kW, enough to recover around 40 kilometers per hour of load.
To use a three -phase P17 socket, this will necessarily become more expensive. Indeed, if the addition of a three -phase P17 socket costs only a few tens of euros at most, it is necessary to a charging cable which is not provided with the vehicle, which can sometimes increase the bill of several hundred euros. The advantage will be an improved charging speed, allowing to recover up to 120 kilometers of autonomy per load hour.
Even if it means spending several hundred euros for a charge point, it is logical to move towards dedicated solutions: Wallbox, or domestic charging stations.
Wallbox or charging station
A wallbox, or charging station, is a term actually designating equipment dedicated to the recharge of the electric car. Unlike the solutions presented above, it is not possible to use a Wallbox for something other than to load an electric vehicle, it will therefore be an investment that will only be used.
Several advantages of wallboxes make them generally quite popular with individuals, despite their high price (between 500 and 1,500 euros depending on the model) without counting the installation which must be carried out by an Ireve Ireve electrician. First of all, there is a undeniable security Unlike other more conventional sockets, in the sense that there is no current until a vehicle is connected to the terminal, and in charge.
In this way, when you are never immune to an accident on a domestic socket, the risk with a wallbox is much more reduced. In addition, many manufacturers of charging stations offer a intelligent integration of their terminals with home automation solutions, as an automatic load at certain time slots, which is practical for people with a hollow hours subscription.
We told you about it in our file dedicated to Wallbox, the “Wallbox” brand offers a solution incorporating a mobile application and an online dashboard grouping all the useful information with regard to recharge: hours, energy consumed, power, power, Cost … In addition, the cable is attached to the charging station, which means that you will not need to plug or unplug your cable with each load:. And unlike the above proposals, you can leave your occasional charging cable in the car.
Tesla also offers its wall connector for 500 euros with attached cable – and of course compatible with all electric vehicles, not only the Tesla – which is an excellent price, but which has some disadvantages in the face of competition. There is no intelligent load piloting, nor the possibility of load shedding, which can be prohibitive for some.
Delics is a very important element according to the power of your electrical installation (in KVA) and the power of all the electrical devices in your home (in KW). Load shedding thus makes it possible to temporarily reduce the load power of the car If you turn on for example your oven and your cooking plates at the same time. Without load shedding, your installation will find it if it is not powerful enough.
The small advantage that the Tesla wall connector will have for owners of the brand’s vehicles is that it includes a small button on the handle of the charging cable to open the car hatch, and thus plug in all simplicity. Aside from that, other references offer more advanced features, but sometimes for much more expensive.
Wallbox is also a good solution for homes that have several electric vehicles to be loaded, with a load power up to 7.4 kW at 11 kW in single -phase or 22 kW in three -phase, it is sometimes enough for a few hours to fill out fully the vehicle battery.
Summary table
We summarize below the different charging solutions with their specificities.
Type of charger | Kilometers recovered in an hour | Maximum power | Price (excluding installation) |
---|---|---|---|
Domestic outlet | 10 to 16 | 1.8 to 3 kW | 10 € |
Reinforced | 20 | 3.7 kW | 80 € |
P17 single -phase | 41 | 7.4 kW | 10 – 50 € |
P17 three -phase | 122 | 22 kW | 10 – 50 € |
Wallbox 7 kW | 41 | 7.4 kW | 500 – € 1,500 |
Wallbox 11 kW | 61 | 11 kW | 500 – € 1,500 |
Wallbox 22 kW | 122 | 22 kW | 500 – € 1,500 |
We considered a Average consumption of 18 kWh per 100 kilometers To try to give an equivalence between charging power and autonomy recovered by load hour.
This should allow you to better understand the ideal solution according to your budget, your use and your future needs. Finally, note that the maximum charging power of the installed wallbox will not necessarily be that accepted by your vehicle: a Tesla Model 3 for example has an 11 kW on -board charger, and even plugging it into a 22 kW wallbox, it does not will charge that at 11 kW.
Conclusion
For those who live in individual housing, installing a charging station or a power outlet is often a formality. However, in shared habitat or in co -ownership, it will be necessary to warn in general meeting the installation of a charging solution, but the work will be able to start before thanks to the right to the right to the right to the right to the right to the right to the right.
If this is not possible for you to install a home load solution, we have a file that summarizes solutions to live as an electric vehicle without the possibility of loading at home, but it will be necessary to accept to walk with different cards recharging, unfortunately.
The fast load remains to be reserved for large journeys, and it should not be imagined as a daily load solution. Indeed, in addition to the costs much higher than the home load (between three and ten times more expensive), the practical side of the charge at home is undeniable.
You have to see the investment of a home charging station as a budget to be added when buying the car, which will always “refuel” at a lower cost. Whatever solution you opt for, you now have all the information you need to make the best possible choice.

Nevertheless, this recharge mode is not very efficient and not very secure, which results in considerably long recharge times and a risk of overheating of the house circuit of the house in the event of intensive recharge. So if it is possible, is that the solution that will suit you best ? Let’s do a check in.
Can we recharge an electric car on a simple plug ?
Yes, it is possible to recharge an electric car on a simple domestic socket if you want to recharge your vehicle at home without having to install any specific device, provided you do not do anything.
Recharge your electric car on a conventional socket is allowed by the majority of manufacturers who provide a charging cable allowing this use. It is therefore quite possible to opt for this daily solution. On the other hand, some prerequisites are necessary to do this.
On the one hand, before choosing to connect your electric vehicle to a simple domestic grip, it is essential to check the compatibility of the electrical network. Indeed, if it is not properly sized, overheating is possible and may cause significant damage. You should know that security is not as guaranteed with the use of a domestic socket to recharge your car as by opting for a charging solution specially designed for this function. Thus, it is imperative to have your installation checked by a competent and specialized electrician and to provide the possible referral required if necessary before considering connecting your electric car to one of your domestic catches.
In addition, whatever the power of your car, recharging its battery through a simple power outlet can only be made a power of 2.3 kW, because the intensity of the current cannot exceed 10 amps. Consequently, recharging your electric vehicle will be very long. Indeed, depending on the power of your battery, you will need to count between 5 hours and 47 hours of load ! So be ready to wait for long hours and make sure your domestic electrical circuit can resist the risk of overheating.
Consequently, if it is possible to recharge an electric car with a simple plug, this recharge mode requires the prior intervention of an electrician in order to verify the capacity of the domestic network to support such prolonged use. In addition, it is preferable to reserve this type of recharge at a night update of the battery after short journeys of everyday life. In the event of larger journeys, the recharging time will be far too long to be comfortable.
What about the reinforced taking ?
To better meet the recharge needs of an electric vehicle without embarking on major work, it is possible to opt for the reinforced taking. If it looks like a traditional socket, it is more efficient for recharging an electric vehicle, but also more secure. Indeed, it delivers a power of 3.2 kW, or 14 amps. Consequently, the charging time is reduced and stretches between 3 hours and 31 hours depending on the power of the battery and the load level of the vehicle.
Reinforced socket is simple to lay. Just call on a competent and authorized technician to connect reinforced socket to the domestic electrical panel through a dedicated line. To compensate for the higher load power than the classic socket, differential protections should be placed. The link with the vehicle is carried out by means of a suitable charging cable.
What other charging solution for an electric vehicle ?
If the simple socket and reinforced socket are not enough to meet your expectations in terms of electric vehicle recharge, there is the charging station, which remains the most efficient and most installed solution to date. The Wallbow is a box that sets up at home for dedicated recharge.
There are several categories of resistant charging stations, classified according to their power. They can indeed deliver 3.7 kW, 11 kW or 22 kW, or even more according to needs and expectations.
If the charging time is much faster, since it oscillates between 1 hour and 27 hours for domestic models, the charging station has the great advantage of being more secure than the other devices mentioned. In addition, it can be set and programmed to better manage electricity consumption in order to make good savings.
Again, it is necessary to call on a professional, who must be certified IRVE (electric vehicle recharge infrastructure).
Thus, if it is quite possible to recharge your electric car with a simple domestic socket, this solution is the least efficient and the least secure recharging methods.
