Install a charging point for electric vehicles in the community or private garage


In the case of having a garage for the car, two things can happen: we have a garage in a house, and being so very probably already has some plug in the garage, or that we have a garage or parking space in a community garage, with more neighbors, which tends to be the most common in Spain. In this case almost no garage has connectors, if any, is from the community.


It should be borne in mind that with a conventional electricity plug, domestic type, 16 A, you can recharge an electric car. This type of plug is for what has come to be known as occasional recharge (which is usually limited to 10 to and about 2.3 kW of power). The most relevant in this case is that the installation of ground contact of the line that feeds this plug is properly installed.



Community Garage:

You only have to inform the community


In the case of a carport or garage in a collective garage installation is a bit complicated, but don't be afraid. As we are talking about having to perform an installation on a common element that is shared with other owners, we cannot act without more, or do whatever we want.


To install a charging point in a community garage, only it is necessary to inform in writing to the President or administration of estates like us gestifinc AF. But it's not worth it in any way.


(The Horizontal Property Law was amended to simplify and facilitate the installation. The 23 of November of 2009 was published in the Official State Gazette number 283 the ACT Government Purchase 19/2009, of confidence-building measures and procedural streamlining of the car and the energy efficiency of buildings, and in its article 17.5 modifies the Horizontal Property Law so that you do not have to submit the installation to the adoption of a board of owners.)


You just have to tell you in writing, in an official manner, the president of the community or administrator of the estate, that is going to perform the installation, and save a copy of the document with time and date stamp or signature.


In compliance with the supplementary technical instruction of the electrotenico of low voltage regulation (REBT), the ITC-BT-52, which regulates the charging infrastructure for electric vehicles.


a)  From our counter


If the garage is in the same building in which we live, the most reasonable thing to do is to make a referral of our individual electrical installation up to the garage, using the same power supply contract of the dwelling. Here there are two options, or carried out from the meter itself of our electricity supply, or carried out from the general control and protection of our home.


The advantage of the first option is that normally the centralization of counters are located on the ground zero, and how the garage spaces are usually on the ground zero or in basement, the distance from the counter to the point of recharge will be lower, and the cost of the installation will also be something minor, having to spend less meters of cable. This option requires electrical meter digital or electronic.


The advantage of the second option is that you can have a direct control of the line that feeds the point of recharge from the dwelling itself, since it would be installed there the automatic switch and the differential switch, or even a small counter, programr, etc. The downside is that the more high is our housing, more meters of cable will be needed to reach the point of recharge.


In principle for a normal charging point, or slow recharge, and about 3.6 to 16 kW of power, it is not necessary to hire a specific supply, with a second contract and a second fixed fee, although it could also be done according to the circumstances.


In fact, many times it will not be necessary or even increase the contracted power that we have in our housing, although this will depend a little of each case. If you look at that degree of electrification has housing, because what we are doing is an extension of the existing installation. The electrician is already pending. The final cost of the installation, in this case, you can be between 800 and 1600 euros.


Not all over the world, in particular certain electrical companies, defends the possibility of installation by deriving from the counter of the user. We will see how is definitely the ITC. Now finds himself in a somewhat legal in certain autonomous communities.


b)  From the counter of the garage


If the garage is not in the same building in which we live, or if it is not possible to perform the derivation from the user's own counter, because the law does not allow it, or because it is very difficult technically, for issues related to the building, you can make the referral from the electric meter's own garage.


Beyond this difference, the installation does not change just with the lead from the meter itself. It is essential to a counter in the lead that will serve for the community of owners of the garage copper to the user the electricity they consume their point of recharge, and have, for example, with the share of the Community.


In this case obviously is not only sufficient to inform the community of owners, but that requires APPROVAL OF THE COMMUNITY.


It is desirable to make it clear that it is not worth 'catch' electricity from a power line that goes to the side of our garage, making a connection or direct derivation. You have to make a new circuit with its own line, specific to the point of recharge. This is particularly so as a matter of security and control, and to prevent overloading a circuit that already exists.


c)  With a new supply


In this case, the installation of the power line to the point of recharge deriving from an existing counter, either from the user, either in the garage, but hires a new power supply, with the fixed cost monthly or bimonthly, and main counter with your own.


C.1) in house:

That is to say, with this solution we would have a contract for the electricity of the house, with their corresponding recurring invoices, and also have a contract for electricity from the point of recharge, in turn with their corresponding invoices. That is to say, it is a solution more expensive for the user.


C.2) in community garage: (requires authorization of the Board)

There are a couple of variations of this system:


The first is the Load Manager. Rather than your own user costee installation, and pay the electric company for the supply and consumption, you can do so through a load manager, which is a company that, without being a power company, deals with solutions of recharging electric vehicles and can resell electricity.


In this case the installation, with the new supply and counter, as well as the own point of recharge, is paid by the Load Manager, and then monthly user pays to the load manager what has been stipulated. That is to say, in this case, it pays for the service, in addition to the consumption. There is usually 'Bono' type solutions (with so many kWh included) or type 'flat rate', as the case may be. This solution can be particularly useful in very large garages.


The other alternative is that new supply with a main counter to several points of recharge. What comes to be called as a trunk installation. The main counter are derived as many counters as recharging points will be. This solution again seems more suitable for large garages, in garages where there is going to be many points of recharge, or in those who are not in the same building as the housing of the users.


What is very complicated installation?


Until the regulations must be complied with in the new building works does not stipulate that provision should be made for (pre), or directly install, recharging points in the garage, and from then on all the buildings already constructed, the installation of a charging point in a garage may be more or less complicated.


What you need to keep in mind is that all the costs of the installation for the user of that point of recharge, and that may not cause damage to the facility or common elements of the building, and in the event that something is damaged due to the installation, you must take care. This on the other hand is all logic and common sense.


In principle, the installation is relatively simple: there is only a cable up to the garage. In a single-phase three-wire really talking about: phase, neutral and earth. In all cases we have stated before, the greatest difficulty is usually to get that cable from the meter to the garage, since the tour can be labyrinthine.


Depending on the location of the garage may be more or less distance to travel, and more or less architectural barriers to overcome: walls, floors, stairs, etc. If the dwelling is not very old may be recessed electrical conductors, generously dimensioned, which can pass the cables. You can also take advantage of the false ceilings and patinillos.


When these lines for facilities not allow having more cables, or when they do not even exist, then there is no choice but to make new pipelines, and very likely to be views, for its lower cost and speed of execution. Within the garage itself that the pipes are not usually a problem because these are now carried out as well. The problem is in other areas. We must try to carry it concealed.


As the case may be necessary to make a hole in something constructive to spend driving with the cable. Obviously pillars and beams, structural elements, should not be affected (screw something to a pillar, yes, boring a beam to pass a cable or pipe, no).


In general  should not be necessary works of masonry. With the views are typically used plastic pipes propagator of the flame. The electrician to carry out the installation is already aware of all the rules and knows how to do its work.


Once the cable has come to the garage, there is placed a control and protection, with differential switch and circuit breaker Circuit breaker, in addition to other elements if they are deemed necessary, and the mural of recharge.


You must choose a database mural of recharge in line with the vehicle


The wallbox can be in different ways: for example, with a hose with cable and connector specific to the electric vehicle that we are going to recharge (with several meters of cable length to arrive without problems), or recharging sockets without more, one or more, with different connectors (i.e. several 'plugs'), where you plug the recharging cable to the vehicle. The outlets will cover, for security.


It should be borne in mind that not all electric vehicles have the same type of charging connector. Electric motorcycles and quadricycles typically use the connector schuko (domestic), while electric cars, vans electric and plug-in hybrids often use the connector Yazaki (Type 1), for example Nissan, Mitsubishi or Chevrolet and Opel, or use the Connector Mennekes (Type 2), for example, Renault, Volkswagen, BMW, Mercedes-Benz or Tesla (not exactly a type 2, but is also compatible)


The safety of the installation of a charging point is more than guaranteed. Right in the shunt is placed a first system of protection of the line in case of any problem cuts the electricity and point. And after the mural has its own electrical protection.


In addition, the bases are designed to be used on the outside and be resistant to splashing water. It should be borne in mind that the own electric vehicles, charging cables and connectors are designed to be used on the outside, exposed to the weather, even if it is raining.


Let us not forget that he who has a charging point in a garage space is not a major problem of safety, as in the garage as there are electrical installation. And for the most scary it is important to remember that the risk of fire of an electric car is less than in a conventional car of a combustion engine (gasoline, although we do not think all day in it, it is much more dangerous than talking to the risk of fire).


So that no other 'catch' electricity of the charging point, that is to say that anyone other than the user can plug in a vehicle or whatever to the point of recharge of the garage, have been thought different locking systems, either by a key or using a RFID card.


Who is thinking of a recharging system wireless through a system of induction, something that you can buy in some countries, should be borne in mind that while you do not need to plug in the car with a cable, if you will also need an electrical installation up to the garage.

A council to end


One last piece of advice: Install a charging point for electric vehicles is at the moment a task quite specific, and although any electrician could do it, the experience and specialization come in handy.


In Spain, there are a number of companies specialized in the installation of charging points, such as Lugenergy or Ibil, although there are also some electricity companies with advice service for it. It is a matter of doing a little research on Google and search for. Some brands of cars are often also advise or to facilitate the installation. There is no other that search and compare service and price.
