The person who knows most about charging points
All the key facts you need to know about charging points, operation, requirements, cost, safety and models. Our expert at Endesa, Juan Ignacio Ferrer, enlightens us.
I have my electric car at home. Do I have to buy a charging point? Compatibilities at home and why a normal socket does not work.
Electric vehicle manufacturers include a cable that can be connected to a domestic socket in a house or parking space. However, it is not the most recommended option: it should only be used for occasional charges, since a charging load that can be supported by the electric installation must be selected.
The installation of a charging point entails a series of advantages, such as:
- Safety: basically, the charging point serves to ensure that the charge works from the start and throughout the entire process under the best conditions. It allows the charging point and the vehicle to “connect” and if by any chance there is a battery failure or problem with the vehicle or the house, the charging will not take place.
- Well-being/comfort: a charging point makes it possible to programme, together with the car, the charging time in order, for example, to charge it at night at a ‘super off-peak tariff’, which is the cheapest. Additionally, if the charging point includes the cable, it is not necessary to constantly fit and connect the plug.
- Speed: a charging point can deliver more power than a domestic socket, enabling a controlled reduction of vehicle charging hours. It is the difference between 16A and 10A (40% faster)
How do the savings work?
It depends on the type of vehicle. In the case of a passenger car, this consumes 17 kWh/100 km on average, which represents a cost of €1.55 per 100 km, provided that it is charged at night at a super off-peak tariff.
In the case of a diesel vehicle that consumes 7 litre/100 km, the cost would be €8 per 100 km (considering a diesel price of €1.152/litre). How much do I save?
Is there specific aid for purchasing the charging point? How much will I receive?
There is aid at both national and regional level. At national level there is the MOVEA Plan, which subsidises both the purchase of the vehicle and the charging infrastructure. The 2017 Plan has not yet been launched by the Government. Read more about 2017 subsidies here.
Do I have to contract more power? What is the minimum power required?
If the charging point is installed in a single-family house, a new electricity supply contract is not required. The electricity installation of the house is used to charge the vehicle when lower power is required: at night.
If the charging point is installed in the garage of a condominium and is located in the same building as the dwelling, a new electricity supply contract is not required provided that the installation can be made from the meter of the dwelling.
Does it mean an extra cost?
There is no extra cost since we do not have to contract a new supply or increase the available power.
If I opt for a collective charging point, do I have to request permission? How do I obtain permission from the residents’ committee?
With the new horizontal property law you do not require authorisation from your residents’ committee to install a Charging Point; it is enough to inform them.
How much will it cost me? Who do I have to call to have it installed? How long do I have to wait? How long does it take to install it?

Endesa has a network of installers specialising in electric mobility who will contact the customer within a maximum of 48 hours to agree upon the two appointments that must be scheduled: the first to prepare a quote and the second to perform the installation, always adapting to the times that best suit the customer.
Once installed… Is it easy to use? Do I just have to plug it in?
Using a Charging Point is very simple.
- Connect the cable to the vehicle.
- Start of charge – End of charge.
- Disconnect the cable from the vehicle.
How long does it take to charge?
Using a conventional 3.7 kW charging point, the estimated time is 4-6 hours. You should ideally charge the vehicle at night between 1 am and 7 am, when household electricity consumption is lower.
(For a battery with a capacity of between 20 and 30 kWh).
How do quick charging, semi-quick charging and normal charging work?
Conventional and semi-quick charging use alternating current and the charging point delivers a maximum of 22 kW.
Quick charging uses direct current and delivers 50 kW, which allows charging 80% of the battery in approximately 30 minutes.
In the near future, quick charging points that deliver much higher power are expected to become available, thereby reducing charging time.
(For a battery with a capacity of between 20 and 30 kWh).
Do the charging points differ?
Yes, they differ. The main difference is the energy delivery mode, since both normal charging points and semi-quick charging points deliver power in alternating current and quick charging points in direct current. The latter are bigger.
Another difference lies in the vehicle’s charging connectors: as in the case of mobile phone chargers, there is no standard. Current connectors for conventional charging are the Mennekes and SAE J1772, and for quick charging the CHAdeMO and CCS COMBO.
Which one is best for me?
A charging point at home is the most efficient and safe way to charge your vehicle. On average, a vehicle covers a distance of 40 km per day, a range which electric cars far exceed.
Quick charging is considered a booster or convenience charge in those cases where we use the vehicle more often and to cover longer distances.
What type of information does the charging point give me?
It depends on the type of charging point installed. There are “Simple” charging points, which do not provide any type of information, and more “Advanced” charging points, which have communications and inform us about charging time, kWh delivered, etc., through an App.
Is my charging point forever? Is it compatible with my spouse’s or neighbour’s car?
The charging point is forever, since in many cases you only have to change the cable and connector depending on our vehicle.
It is compatible provided that both vehicles use the same type of connector and they are near the charging point.
Can I also charge my electric bicycle there?
Bicycles are charged in a domestic or Schuko socket. They do not need a charging point.
