Electricity can increase the energy efficiency of road vehicles and contribute to the reduction of CO2 in transport. It is the essential source of energy for the development of electric vehicles, including light electric vehicles, which can help improve air quality and reduce noise pollution in urban or suburban agglomerations and other densely populated areas.

The Government presented the April 6, 2010 the Comprehensive Strategy to Promote Electric Vehicle with horizon 2014, with different programs for the implementation of measures that include the phenomenon from its various facets: stimulating demand, manufacturing and R & D + i, horizontal and building charging infrastructure and energy demand management actions. Under this latter area, it was said in that document that the priority supply infrastructure must be a partner to the purchase of electric vehicles (related infrastructure) own element, involving other infrastructure to recharge energy services.

The Royal Decree-Law 6/2010 of April 9, measures to boost economic recovery and employment, reformed Law 54/1997 of 27 November, the Electricity Sector, inter alia, to include a new agent industry, called "transmission system loads", whose primary function is "energy delivery through services for recharging electric vehicles using electric motors or batteries storage conditions which enable convenient recharging and cost minimum for the user and for the electrical system through integration with future technological recharge systems are developed. "This does not prevent holders use non-public car parks can make the appropriate facilities and manage their own supply or make an internal impact of expenses.

In developing the forecast of the Royal Decree-Law 6/2010 of April 9, Royal Decree 647/2011, of May 9, has regulated activity manager system for carrying loads recharge energy services while created supervalle access fee in order to optimize the use of existing electrical power generation, optionally available in both free market and at last resort tariff, which will make available to the users cheaper refills in the relevant time periods, while the electrical system offer the possibility of improving overall efficiency by a flattening of the demand curve. This is estimated that needs could be met up to 5 million electric vehicles without increasing power generation.

The definition of the position of manager loads was subsequently endorsed by the new Law 24/2013, of December 26, the Electricity Sector, which in Article 48 defines recharge energy services and the obligations and rights managers loads.

According to Article 48 of the Electricity Act, energy service main function will recharge energy delivery services by charging electric vehicles and battery storage conditions allowing the load efficiently and minimum cost to the user and to the electrical system. To ensure the security of facilities charging electric vehicles, and to facilitate its operation by standardizing the minimum cost, it is necessary to develop the appropriate technical standard.

In the European Union are discussing technical issues and preparing policy strategies to promote alternative energy and its use. The European Commission published on 24 January 2013 a "Communication to the European Parliament, the Council, the European Economic and Social Committee and the Committee of the Regions. Clean energy for transport: European strategy on alternative fuels "and most recently" Directive 2014/94 / EU of 22 October 2014, the European Parliament and of the Council on the implementation of an infrastructure for fuel alternative ", aimed both are initiatives to promote so-called" alternative fuels "and, in particular as regards the electric car, the adoption of a model of common connector for electric vehicles in the European Union and the promotion of the necessary infrastructure for recharging electric vehicles.

According to these European policies and in particular in accordance with Directive 2014/94 / EU, Member States of the European Union should ensure that an appropriate number of charging points available to the public to allow electric vehicles moving at least believe in suburban or urban agglomerations and other densely populated areas and, where appropriate, within networks that will determine these Member States. For example, the number of these points publicly accessible recharging shall be provided by national policy frameworks to be communicated to the Commission before 18 November 2016, taking into account, among other factors, the estimated number of electric vehicles enrolled at the horizons of 2020, 2025 and 2030 in all Member States. As an indication, the appropriate number of charging points should be at least equivalent to a charging point 10 vehicles, also taking into account the type of vehicle charging technology and private recharging points available. Public authorities of each Member State shall take measures to help vehicle users ensuring that developers and managers of local infrastructure facilitate sufficient charging points for electric vehicles.

These, and any other initiatives from the EU, should be taken into account, and the relevant legislative acts adopted by the European Parliament and the Council, shall apply to the terms to be determined, so that appropriate provisions should be made to welcome any new information that comes from those instances in the future. Likewise, in the light of developments in the introduction of electric vehicles, it should be possible to adapt flexibly to possible new needs.

This royal decree coverage is first on the final disposition of that cuarta.1 Electricity Act, which enables, in general, to the Government for the scope of its powers, issued the regulations necessary for the development and implementation of this law. But also, secondly, more specifically, also is covered in Article 53.9, which provides that the production facilities, transportation, power distribution and direct lines, intended for reception by users, consumer equipment as well as technical and material elements for electrical installations must meet appropriate safety techniques and industrial quality in accordance with the provisions of Law 21/1992, of July 16, Industry, and other regulations that are application.

Moreover, one of the purposes of the Law 21/1992, of July 16, Industry, is to contribute to industrial activity compatible with environmental protection, which is closely linked to energy efficiency and savings and the use of renewable energy. Moreover said Industry Act provides in Article 12 that safety regulations establish the technical conditions or safety requirements by object must meet the facilities, equipment, processes, industrial products and their use, as well as technical procedures to assess compliance with those conditions or requirements.

Furthermore, Article 12 of the Law of Industry, in section 5, determines that industrial safety regulations state level be approved by the National Government, notwithstanding that the regions with legislative jurisdiction over industry can enter additional requirements on the same matters in the case of installations located in their territory. In furtherance of that legal provision was issued Royal Decree 842/2002 of 2 August, amending the Regulation for Low Voltage Electrical approved.

So this royal decree is the appropriate framework in the Industry Act and the Electrical Low Voltage Regulation amending and complete, to establish the technical specifications that enable the safe charging of electric vehicles in any of the situations expect. To do so, by this Royal Decree a new complementary technical instruction (ITC) added to those already listed in the Electrical Low Voltage Regulation, approved by Royal Decree 842/2002 of 2 August, called ITC BT-52 is approved "Facilities for special purposes. Infrastructure for recharging electric vehicles, "whose purpose is to regulate the efficient and safe power charging stations. Simultaneously several other instructions that which consequently affected change.

According to what is established in the indicated new complementary technical instruction regarding equipment and materials, charging stations with elements of standard and technically secure connection should be used as an instrument of transmission charges or expansion of facilities individuals.

In addition, through the first additional provision allocations minimum structure for recharging the "electric vehicle" in buildings or parking lots of new construction and roads, provision, coverage is provided for in Article 3 of the Act are prescribed 38/1999 of 5 November, Building Management and Articles 82.2, 101 and 104.f) of Law 2/2011, of March 4, Sustainable Economy.

Because of the novelty of the subject, to provide for the development of a technical guide that can give practical issues that may arise in the development of the guidelines, which is done in the second additional provision.

In short, this Royal Decree is a regulatory standard for industrial safety in energy facilities in accordance with the provisions of Law 21/1992, of July 16, Industry and Law 24/2013, of December 26, the Electricity Sector, although their first additional provision should also be put in relation with Law 38/1999 of November 5, Building Management and Law 2/2011, of March 4, Sustainable Economy.

With regard to jurisdictional order, this royal decree is issued under the provisions of the rules 13th and 25th Article 149.1 of the Spanish Constitution, which they attribute to the State the exclusive competence on bases and coordination of planning general economic and bases of mining and energy, respectively regime activity. In any case, this regulation has the character of basic legislation and collects forecasts exclusive character and very technical, so that the law is not an appropriate instrument for its establishment and is justified approval by royal decree.

For its preparation, this Royal Decree has been submitted to hearing procedure prescribed in Article 24.1.c) of Law 50/1997, of 27 November, the Government, including consultation to the autonomous communities and the most representative entity local authorities as well as the provision of information on technical standards and regulations and of rules on information society, regulated by Royal Decree 1337/1999, of July 31, for the purposes of implementing the provisions of Directive 98/34 / EC of the European Parliament and of the Council of 22 June, amended by Directive 98/48 / EC of the European Parliament and of the Council of 20 July. It has also been reported on by the Coordinating Council of Industrial Security, as required by Article 2.d) of its Rules, approved by Royal Decree 25/1997, of 21 February.

The installation of the SPL will be optional in new buildings at the discretion of the promoter and existing facilities at the discretion of the holder of supply, or, where appropriate, the Board of Proprietors buildings. The sizing of facilities link and load forecasting is done considering a simultaneity factor loads of electric vehicles with the rest of the facility equal to 0.3 when installing the SPL and 1.0 when not install . As input SPL measurement receive current through the LGA.
 
Pedificio = (P1 + P2 + P3 + P4) + 0.3 ∙ P5 (the SPL is installed)
 
Pedificio = (P1 + P2 + P3 + P4) + P5 (the SPL is not installed)
 
where:
 
P1 corresponding to the set of dwellings obtained as the number of dwellings by the coefficient of simultaneity in Table 1 (ITC) BT-10 Loading.

To calculate the number of charging stations in a circuit of collective recharge and simultaneity between them according to the scheme 4b shall apply as indicated in paragraph 4.1.
 
5. General Installation Requirements
 
In confined areas of buildings for parking or collective parking public or private use, you can perform the operation of battery charging where this operation is carried out without gassing during charging and that the premises are not classified as local with risk of fire or explosion in a (ITC) BT-29. In the place where the electric vehicle charging is carried out a reflective sign will be placed at the point of recharge to identify which is not allowed to recharge batteries with gassing.
 
Collective recharging circuitry preferably fro for common areas.
 
For 1a, 1b, 1c, 2, 3a and 3b schemes, the main pool will be located on the premises or enclosure to house the concentration of accountants or, if that is not enough space, new premises will enable effect or cabinet according to requirements (ITC) BT-16. When secondary meters are installed, they will be located in a closet in an envelope or in a SAVE.
 
It is permissible for the general line supply has lead to lower section if the protection of such derivations overcurrent is guaranteed. To that end, schemes 1b, 1c and 3b, may be included in the junction box necessary protections with fuses or circuit breaker.
 
When a collective recharging circuit that feeds several charging stations (according to 1a or 1b scheme), each circuit will start installing a circuit breaker for protection against overloads and short circuits. Upstream of each circuit breaker and the same picture will install an IGA (automatic main switch) for the general protection of all circuits recharge.
 
In car parks and parking lots, the scorecard and protection associated with charging stations will be identified in relation to the square or assigned parking spaces. The items to be installed in this table are defined in paragraph 6.
 
Dashboards and protection, or if the SAVE with integrated protection, must have locking devices to prevent tampering of the controls and protection.
 
The power installed in the three phase circuits according collective refill Scheme 1a, 1b or 4b is usually set to one of the steps in the following table, although the designer may justify a different power, in which case the protection circuit will be sized and commensurate with the expected power.

Monophasic recharging stations will be divided equally among the three phases of collective recharging circuit. The maximum number of charging stations for each collective recharging circuit indicated in Table 2, was calculated assuming that the seasons are single and a unit power of 3,680 W. The designer may extend or reduce the number of charging stations if justifies an installed capacity respectively lower or higher station.
 
Forecasts power and circuit characteristics collective or individual recharge scheduled for charging mode 4 shall be for each particular project.
 
The lighting system in the area where the realization of recharge is intended ensure that there is a minimum horizontal illuminance level during operations and maneuvers required for the initiation and termination of recharge ground level of 20 lux for charging stations foreign and 50 lux for indoor charging stations.
 
The maximum permissible voltage drop on any circuit from its origin to the point of recharge will not exceed 5%. Drivers used will usually copper and its section not less than 2.5 mm2, although aluminum may be different facilities or group homes parking in residential buildings, in which case the minimum section is 4 mm2. Whenever aluminum conductors are used, the connections should be made using proper techniques to prevent the deterioration of the conductor due to the occurrence of hazardous potential, caused by galvanic couples between dissimilar metals.
 
In facilities for recharging electric vehicles, having more than 5 charging stations, for example, dedicated specifically to electric vehicle charging stations, the designer will consider the need to install filters harmonic correction, in order to ensure that harmonic voltage distortion remains as the characteristic limits the voltage supplied by public distribution networks, so that other users who are connected to the same network point not harmed.
 
The circuit supplying the charging point must be a dedicated circuit and should not be used to power any other electrical equipment unless auxiliary consumption related charging system itself, among which the lighting may include the docking station.
 
Fixed installation for electric vehicle charging must have bases outlet that is appropriate for the charging mode and location of the charging station in accordance with paragraph 5.4, so as to avoid the use of extension cords or adapters by Ratings recharge services.
 
In all cases, but especially so in existing buildings, the designer of the installation check that the ampacity of the general power line (or individual referral in case of houses) is not exceeded, taking into account the forecast capacity of each charging station and the simultaneity factor proceed as indicated in paragraph 4.
 
The installation for electric vehicle charging can be projected as an extension of the existing facility or a low voltage direct power distribution network through a separate installation own existing link.
 
For any facility dedicated to recharging electric vehicles, the following general requirements apply:
 
5.1 Power. The nominal voltage electrical installations for recharging electric vehicles powered from the grid will 230/400 V ac for charging modes 1, 2 and 3. When required to install a charging station three power and the existing supply voltage is 127/220 V, proceed to its conversion to phase 230/400 V.
 
In the charging mode 4, the voltage refers to the input voltage of the AC-DC converter, and can reach up to 1000 V ac and 1500 V dc current phase.
 
5.2 Systems neutral connection. To enable protection against indirect contact by using residual current devices in special cases where the installation is fed by a TN system, will be used only in the form TN-S.
 
5.3 Pipes. The pipes required for the installation of charging stations shall comply with the requirements established in the REBT ITC different depending on the type of premises where it is to do the installation (local public assembly, local special features, etc. ).
 
The cables from the SAVE up to the connection point forming part of the fixed installation (see Figure 3, case C-shaped connection) should be a minimum rated voltage 450/750 V, with copper conductor class 5 or 6 (suitable for mobile applications) and resistant to all the conditions in the place of installation: mechanical (eg abrasion and impact shocks or crushing), environmental (eg presence of oils, ultraviolet radiation and extreme temperatures) and security (eg deflagration or vandalism).
 
When power cables charging stations run through the outside, these will be rated voltage 0.6 / 1 kV.
 
5.4 Connection Point. The connection point must be located next to Plaza feed, and fixed installation in an enclosure.

Whatever the scheme used, protection of installations of electrical equipment must be secured by differential protection devices. Each connection point must be protected individually by a maximum differential protection device Residual Current-rated 30 mA, which may be part of the fixture or be within the SAVE. To ensure selectivity differential protection installed in the source circuit or collective charge is then selectively delayed with installed downstream.
 
The current devices are Class A. The differential protection devices installed on public roads be ready so you can install an automatic reset and installed in public car parks or at stations for electric mobility will have a warning system switch or shall be equipped with an automatic reset.
 
6.2 Protective measures according to external influences. The main external factors to consider in this type of installation are:
 
For outdoor installations: Penetration of solid foreign bodies, water penetration, corrosion and UV resistance.
 
For installations in car parks or public, private or public road parking: competence of people who use computer.
 
In all cases, mechanical damage.
 
The designer should pay particular attention to existing external influences on the site where the facility is located to discuss the need to choose higher or additional features that are prescribed in this section.
 
When the charging station is installed on the outside, teams must ensure adequate protection against corrosion. To this end the provisions included in the (ITC) BT-30 will be considered.
 
The degree of protection against ingress of solid objects and access to hazardous parts, against ingress of water and against mechanical impacts of charging stations may be obtained by using multiple enclosures provide the degree of protection required all the surround completely mounted. In this case, the manufacturer's documentation of the charging station must be closely defined the method for obtaining different degrees of protection IP and IK.
 
6.2.1 Degree of protection against ingress of solid objects and access to hazardous parts. When the charging station is installed outside the piping must ensure minimal protection IP4X or IPXXD.
 
Charging stations and other electrical panels have a minimum degree of protection IP4X or IPXXD for those installed in the interior and IP5X to those installed outdoors. The degree of protection specified for the charging station does not apply during the charging process.
 
6.2.2 Degree of protection against water penetration. When the charging station is installed on the outside, the installation should be as indicated in Chapter 2 (ITC) BT-30, ensuring, for both pipes one IPX4.
 
Charging stations and associated electrical panels have a minimum degree of protection IPX4. When the base of socket or connector does not comply with the above IP level, it must provide it's own charging station by its design. The degree of protection specified for the charging station does not apply during the charging process.
 
6.2.3 Degree of protection against mechanical impacts. The equipment installed in locations where electric vehicles circulate must be protected against external mechanical damage rate impact of high stringency (AG3). Computer protection is ensured by means of any of the following means:
 
a) By placing the electrical equipment in a location where it is not subject to a foreseeable risk of impact.
 
b) arranging any additional mechanical protection in areas where the equipment is subject to the risk of impact.
 
c) selecting the electrical equipment with a degree of protection against mechanical damage under specified in paragraphs 6.2.3.1 and 6.2.3.2.
 
d) Using the combination of some or all of the above.
 
6.2.3.1 Protection of the envelopes. When electrical equipment protection against mechanical damage is ensured by enclosures, once installed they must provide a degree of protection against external mechanical impacts IK08.
 
The body of charging stations and other electrical boxes located abroad have a minimum degree of protection against external mechanical impacts IK10. The body of charging stations excludes parts such as keyboard, LED screens or vents. The degree of protection specified for the charging station does not apply during the charging process.
 
6.2.3.2 Protection of the pipes. When the pipes are installed in a location subject to mechanical risk areas, such as electric vehicles circulation damage, they present adequate resistance to mechanical damage. In these cases, the tubes present a minimum resistance to impact grade 4 and grade minimum compressive resistance 5. If protective channels are used, they present minimal resistance to mechanical impacts IK08.
 
In other drive systems that do not provide mechanical protection to the cables, protection is ensured through the use of additional mechanical means, eg using armored cables.
 
6.3 Measures of protection against overcurrent. Charging circuits, to the point of connection shall be protected against overload and short circuit devices universal cut curve C, sized according to the requirements of (ITC) BT-22.
 
Each connection point must be protected individually. This protection may be part of the fixed installation or be within the SAVE.
 
In facilities designed for charging mode 1 or 2 wherein the charging point is constituted by sockets comply with UNE 20315, circuit breaker that protects every shot should have a maximum rated current of 10 A, although it may use a rated current of 16 A, provided the manufacturer of the base ensures that is protected by this circuit breaker operating conditions provided for slow recharging of electric vehicle recharging eight-hour day, the intensity of 16 A.
 
The facilities provided for charging mode 3, the selection of the circuit breaker protecting the circuit that feeds the charging station ensure proper circuit protection, while avoiding the nuisance tripping of protection during charging. For selection can be used as reference documentation station manufacturer. The tolerance corresponding to the load current signal, the internal consumption of own charging station and installation environmental conditions justify the rated current of the circuit breaker is in some cases greater than the sum of rated currents that can supply the connection points of the charging station.
 
6.4 Measures of protection against surges. All circuits shall be protected against temporary and transient surges. Protective devices against temporary overvoltages are provided for maximum phase to neutral voltage up to 440 V. The devices temporary overvoltage protection must be adequate to the maximum voltage between phase and neutral planned.
 
The device surge protection should be installed in the vicinity of the origin of the installation or the main control panel and protection, as near as possible to the source of the electrical installation in the building. Depending on the distance between the charging station and device surge protection upstream, it may be necessary to project the installation with a protection device further surge next to the docking station. In this case, the two devices surge protection must be coordinated.
 
In order to optimize continuity of service in case of destruction of the device surge protection because of a lightning discharge greater than the maximum possible intensity, when the surge protection device not lead built his own protection, you must install the protective device recommended by the manufacturer, upstream of surge protection device in order to maintain continuity of the entire system, thus preventing the firing of the main switch.
