The socialization of plug-in electric and hybrid cars is slowly catching on. Increasingly, zero-emission vehicles are spreading with greater acceptance among drivers, arouse more interest and have a greater infrastructure, although in this regard there is still a long way to go.

If you are one of those drivers who are considering buying an electric car there will be an immediate question: how do I charge it? Today we are going to try to answer the fundamental question when recharging the batteries by installing a recharging point at home.

Where to recharge an electric or hybrid car?

Either with an electric car with just the autonomy for the day to day or one of the last large capacity electric cars that can allow us to circulate for several days without connecting it to the grid, the most common and except for some lucky cases who wants an electric car You will have to consider installing a charging point in your home .

This means that in most vital situations, the aspiring owner of an electric car will have to have his own garage space . If you are one of the (many) who park their car on the street and do not have access to a charging point on a regular basis, the most convenient thing is to rule out the purchase of an electric car at least for now.If it is a matter of environmental awareness , in exchange you can consider the purchase of another type of alternative car such as electric hybrid (autonomous recharging), plug-in hybrid (they do not need to be connected to the network for many hours), gas or, in case of have very full pockets (and a hydrogenerator nearby), fuel cell.

In the event that the purchase of an electric car continues, we can recharge it in three ways :

  • First, the most common and practical: recharge in our house with its own charging point. Electric cars will need a good number of hours to refill their batteries after daily use. As we have already seen when explaining how much it costs to recharge an electric car at home , slow speed domestic recharges are affordable using the super valley section. In return, we will have to install a charging point.
  • Also, those who have the opportunity will be able to resort to the use of free normal speed recharging points . Obviously in this case it is even cheaper, the biggest handicap is that this type of charging points located in work centers are not very common and, although we work in one of these centers, we will not always be able to connect or not long enough.
  • The last option is to use public charge points . In general, these are slow charging points in which we will have to leave the car generally for a limited time, which will prevent making full charges. If they are semi-fast, fast or super-fast charging points, we will be able to get full charges, but in exchange for a high cost and a greater degradation of the batteries in the high power posts.

 

Both public and private recharging points and from those with a power less than 7 kW to those that can exceed 100 kW will be eligible.
The subjects who can apply for the aid of the MOVES 2020 Plan are individuals, self-employed persons and legal entities such as companies, communities of owners, local entities and public entities.

There are also some brands that are facilitating their customers to enter the electrical world independently or through partnerships with third parties. Kia, together with Repsol, is promoting the installation of charging points in homes, Mercedes-Benz and Endesa are doing the same for their plug-in hybrids and Volkswagen is offering its own charger for the Volkswagen ID.3 at a price of 399 euros.

How much does a charging point cost?

If we have to face the cost of installing a charging point in our house, we must bear in mind that the total cost can easily exceed 1,000 euros , because not only do you have to pay for the wallbox itself.

On the one hand there is the charger that we will leave installed on the wall that will be very specific to the make or model of the electric car, or a generic charger. Its price depends on how many connections it has, if it has security elements (key or card), if it has a hose or not, or if it has electronics to program recharging or measure consumption. As a point of reference, only the Volkswagen ID.3 wallbox costs 399 euros .

At this cost we must add the rest of the installation , adding the necessary wiring that goes from the connection point to the wallbox. In addition to the additional cable, it will also be necessary to add the protection elements such as cable ducts, supports and other hardware to carry the current to our garage in a clean and professional way.

Finally, we must add the cost of the professionals involved in the installation , such as the installation electricians. The best thing is to go to professionals or companies dedicated either expressly to the installation of charging points or who already have experience in the matter. The choice of the electrician in question can be your own or let us recommend it by the dealer, by our own electric company or by a charge manager (they sell the recharging point and electricity).

The installation of a charging point in a single-family house is relatively simple. The work will be minimal and only cables will have to be passed from the light point of the home to the garage. In the case of living in a house with a community garage, the installation will be somewhat more laborious.

The first thing will be to inform the community . It is not necessary to ask permission from the community of owners but to notify the administration in writing, according to the modification of the Horizontal Property Law . The next step is to carry out the installation in the most discreet way possible and in accordance with the Complementary Technical Instruction ITC-52 of the REBT .

And what do I do if I don’t have a garage space?

Having a property with a garage makes things much easier, but does not make it impossible if we do not have our own garage. If we have a rented garage space it leaves us some options, while parking on the street completely rules out any possibility.

With a rental space the first modus operandi would be to propose to the owner to take care of 100% of the cost of the installation ourselves . As it is a high cost, the best thing is that we know that we will keep that position for a long time to amortize its cost with the use of the electric car.

At the other extreme we can propose to the owner that it is he who pays the cost of installing the wallbox. At the end of the day it will be a garage equipment that in the future could offer to other interested parties, charging even a little more for it, but it is not usually a very attractive option for the owners.

The intermediate point would be to assume the costs halfway . So on the one hand the owner would pay all the pre-installation (wiring, protections and installation) and we will be the ones to take care of the charger itself. If in the future we leave the plaza we could disconnect the wallbox and take it with us and the owner of the plaza would leave the pre-installation installed.

How is the installation of a charging point?

To carry out the installation, three procedures can be followed depending on where the installation starts from:

  1. From our own supply line. If we take electricity directly from the same line as the electricity we use at home, things are simplified, relatively. On the one hand, we will not have to make another new contract, but if we have a community garage, the installation will have to be done from our own meter, which can be in a meter room, in the garage itself or at our home, which would force us to put many meters of wiring.
  2. From the garage supply line. If we opt for this option, the installation is easier, but we would have to ask the community of owners for permission, since we are going to use the existing installation and we are going to consume electricity from the garage, so a secondary meter will have to be installed so that it can be community passes that expense to us.
  3. With a new supply line: The most complex option that should only be considered as a last resort is the installation of a new supply line, a new meter and a new contract. In this case we would have a higher fixed cost by having to assume the cost of the contracted power of our home and also that of the charger.
