When it comes to installing a charging point for your electric car at home, it is important that you do not do it in a crazy way. An OCU report answers some questions we are likely to ask ourselves when making this decision.
If you are going to buy a car with a plug (plug-in hybrid or electric) it’s almost done It is essential to have a charging point at homebecause always recharging it at public chargers is not worth it, in addition to your convenience. Arriving home, plugging in the car and knowing that the next morning it is 100% charged gives a lot of peace of mind.
With the decision already made, We can then ask ourselves if it is complicated to set up the charging point and if the facilities are safe and work well.. From the OCU they respond to us.
A normal plug may not be enough
If your car is a plug-in hybrid, a regular power outlet (Schuko, round with ground connection) of 16 amps may be enough to replace the energy spent in the day. It could also be valid for a fully electric vehicle if you travel more than 100 km a day.
However, It is always preferable to put a charger (wallbox), since it provides more security, especially if you use the car for longer trips. With a normal plug you would need many hours to recharge and the socket can overheat causing a short circuit, a fire…, they explain from the OCU. It will also depend on the charging power your car supports.
The most recommended “plug”
The charger you will need and its power will depend on the type of plug-in car you have and the kilometers you drive daily.
To install this charger you need, first of all, to have a garage or a parking space. These are the situations that can occur.
- In a single garage: the process is easy. Find an authorized installer who will place the charging point where it is convenient and connect it to your home meter.
- In a neighboring building: You must notify the community of owners, but it does not require a permit. Typically, the charger will be connected to your individual electricity meter and the cable runs can be long.
- The garage space is not located in your home: You would have to make a specific electricity contract for them to install a meter.
- In garages with a single common meter: You should reach an agreement with the neighbors so that they bill you for the energy consumed.
What is the best power to hire?
The home charger powers they tend to oscillate between 16 A in single-phase current (normal in homes), and 32 A in three-phase current. The nominal power of the charger is the maximum it can provide, but in practice they are usually limited so that they do not exceed the power you have contracted with the company or the power supported by your electrical installation, the OCU clarifies. The more powerful the charger, the shorter the recharging time.. It is advisable that to recharge an electric car you use a charging power of at least 7.2 kW, which a wallbox gives you. This way you will get a full fast charge, in 5 or 6 hours, Hyundai says.
This is how the installation should be
Charger regulations require that the circuit has its own control and protection panelwhich must have a lock if it is in a collective garage. Although it is not mandatory, it is advisable that the cables rest on metal trays that facilitate their laying and it is prohibited for them to pass through another neighbor’s square. All connection points must be securely secured and protected with “ferrules” if cables are larger than 6 mm.
If we talk about prices
How much do home chargers cost? The best sellers, according to OCU data, range between 500 and 950 euros. The cost of installing them varies, since it depends on the distance from the meter to the square, whether there are already cable trays in the garage, the type of protection panel, etc. Installation prices range between 1,000 and 2,000 euros which, added to the charger, places The investment between 1,500 and 2,500 euros.
Generally, you must obtain a new electrical bulletin issued by an authorized installer who verifies the safety of the installation. Some car manufacturers offer to install the charger for you for free, a service that is usually included in the price of the vehicle.
Currently, the Moves III Planmanaged by the CCs. AA., offers aid of up to 70% of the installation cost or 80% in towns with less than 5,000 inhabitants.
