    PROCEDURE AND RECHARGE SYSTEM OF ELECTRIC VEHICLES FIELD OF THE INVENTION
    The present invention is framed in the field of the electric vehicle industry. More specifically, the invention relates to a method and a system for recharging the batteries of said vehicles, designed primarily to obtain greater use and efficiency in recharging times, as well as to facilitate the management of energy resources and associated costs. to the same.
    BACKGROUND OF THE INVENTION
    Currently, due to the increasing amount of CO2 and other greenhouse gases emitted into the atmosphere, the electric vehicle is beginning to be considered not only as an alternative, but as a necessity to combat the pollution of large urban centers. That is why, in a growing number of cities around the world, there are already multiple rental services for electric vehicles, with fleets whose typical number is usually on the order of hundreds of vehicles. However, the implementation of these services is growing strongly, so in a few years these fleets can easily increase up to thousands of vehicles in the capitals of the more developed countries.
    Also, the growth of the sale of electric vehicles is exponential today, and is expected to continue with the same trend in the coming years. As an example, worldwide sales of electric vehicles have increased from about 13,000 units / year in 2009 to more than 740,000 in 2015. However, despite the growing demand experienced by this sector, electric vehicles continue to have operating problems and logistics, derived from the recharging processes of batteries to be applied on this type of vehicles, and the still low availability of sufficient recharging points to meet the needs of users. On the other hand, due to the high capacity of the batteries of some electric vehicles (which can reach up to 120 kWh), it is vitally important to create efficient and intelligent systems to recharge them in an optimized way.

    Another factor to consider, in countries like Spain, is the high price of electricity. In fact, Spain is one of the countries in the world with the most expensive energy rates, being the second most expensive country in Europe in terms of the price of kWh. In addition to this factor, it is important to keep in mind that the price of electricity is not constant, as it varies according to the schedule. This feature is not unique to Spain, and is reproduced in numerous countries such as the United States, Canada, United Kingdom, France, Portugal, Finland, Lithuania, Latvia, and it is also planned to implement in China, where smart meters are already being installed. Figure 1 of this document shows, by way of example, three price / demand curves associated with different rates existing in Spain and belonging to the state of the art, represented according to the time of day.
    Within the different solutions designed to efficiently manage the recharging processes of electric vehicles in different areas, systems and procedures are known, based on the network processing of information associated with the supply or demand of electricity, or user habits, such as the cases of US patent applications US 2015/0077054 A1 and US 2013/0179057 A1.
    Document US 2015/0077054 A1 refers to a system and method for charging batteries in electric vehicles, whose main objective is to provide different charging patterns taking into account the conditions of the electricity grid or the demand for electricity in real time. To do this, US 2015/0077054 A1 proposes a system for connecting the battery electric vehicle to a power source, using a charger configured to generate charging instructions based on a historical charging profile, historical temperature data, historical data solar behavior or information associated with the power grid, and provide charging instructions to said charger. Alternatively, charging instructions can be calculated in the absence of network load data, in real time.
    The described system can also be configured to automatically obtain historical load profiles, weather forecasts or other data through a cable and / or wireless data network. For example, the system may be configured to update information with vehicle data, different load profiles or process data from a remote source in real time. For example, the data can be updated

    every hour, daily, weekly or monthly. The system can also be connected to a data network to which the vehicle and / or the load equipment belongs, where one or more of the components of said network can be located at a distance from the user's premises, for example by means of the use of services in a storage cloud, or a data server connected to the Internet.
    For its part, US 2013/0179057 A1 describes different network charging services, applicable to one or more electric vehicles. The invention described in US 2013/0179057 A1 is proposed as an alternative to known driver assistance systems in determining the appropriate time to charge your electric vehicle, and for the location of en route charging points that fit your Real-time needs. In this context, the document US 2013/0179057 A1 proposes a system configured by software, which allows to condition the processes of loading the vehicle to different sources of information, related for example with the patterns of use of the vehicle, the user's driving style , of the planned routes, of the existing traffic conditions, or of the current charge level of the vehicle's batteries, to determine if it will have sufficient scope to complete the proposed trip.
    In another aspect, the system of US 2013/0179057 A1 comprises data processing means to provide information to the user regarding the points of loading of the vehicle, such as its proximity to one or more scheduled routes, to determine suitability of said points for vehicle loading, to check their availability or to make reservations for their use. It is also possible to use information related to electricity prices to suggest periods of charging during which it is cheaper, or also to allow configuring said charge only for a certain price range.
    In an embodiment of the system, it is also possible to present the vehicle charging services to the user through communications between a client device (for example, installed in the car itself, in a mobile terminal or on a computer) and a remote central server , said elements being communicated through a data network.
    Although the previous examples constitute valid solutions to provide an improved management of the electric vehicle charging processes, they have some limitations and technical problems that remain, still unresolved in the state of the art. Sayings

    Problems are mainly related to the specific planning of the charging processes, while the vehicle is plugged into a recharging supply point. In this context, although systems such as those described in US 2015/0077054 A1 and in US 2013/0179057 A1 may be helpful in determining when it may be more economical to recharge, or at which supply station there may be plug availability To this end, none of them allows flexible, efficient and autonomous decisions to be made about how the recharging process should be carried out specifically during the period in which the vehicle remains connected to the charging device.
    It is important to clarify, at this point, that the complete recharging of an electric vehicle requires several hours to complete, and this causes users to regularly perform other activities while said process is completed, for example taking advantage of night periods, or working times . Therefore, it often happens in these situations that the time available for recharging (that is, the time the vehicle is stopped) is longer than the time required to fully charge the battery. In these cases and according to the systems currently available, the user has to choose when the vehicle will recharge manually, guided by the information provided by the system.
    In the same way, on other occasions it may happen that the times required to complete the recharging of the battery are longer than the times available by the user, for example when it is only possible to stop the vehicle for a limited time taking advantage of specific road stops, breaks for lunch, etc. In this situation, an adequate planning of the load can help to obtain a greater use of the electricity available in those times, and also of the costs incurred.
    The known procedures and recharging systems also do not take into account the diversity of existing batteries and electric car models, which can significantly impact the required recharging processes and times. The absence of differentiation between some models and others makes, in practice, that the recharging is carried out identically regardless of the vehicle to be charged, the capacity and performance of its battery or its specific requirements. This implies, therefore, a source of reduction in the performance of the load provided. In practice, the recharge behavior of a battery is parameterized by means of recharge efficiency curves, as shown by way of example in Figure 2 of this document. In said Figure 2,

    represents the state of charge (in English, "State of charge" or SOC) depending on the time of connection to a current point. The SOC is therefore a value equivalent to the fuel tank indicator in a vehicle, but relative to the battery packs present in both battery electric vehicles (BEV), non-pluggable hybrid electric vehicles (HEV), or plug-in hybrid vehicles (PHEV) .SOC units are therefore percentage points (0% = empty; 100% = complete) An alternative form of the same measure is the depth of discharge (DoD), the inverse of the SOC (100% = empty; 0% = complete) The SOC is normally used when talking about the current situation of a battery in use, while the DoD is used more frequently when talking about the battery life after repeated use.In this context and as mentioned above, each battery model usually has a behavior single recharge and parameter trizable, which presents variations compared to other battery models. Likewise, and as shown in Figure 2, the battery recharge curve does not generally have a linear behavior, which makes some sections of charging require a longer time than others, until reaching a SOC of 100 % (Full load).
    As described in the previous paragraphs, it is necessary, in the present technical field, to develop technical solutions that allow obtaining intelligent charging systems and procedures, which, taking into account the characteristics of electric vehicles, user preferences, the price of the electricity and the time available for its connection to the charger device, carry out a planned, autonomous and efficient recharge, so that the vehicle can be optimally recharged, thereby reducing the cost of the energy consumed during the service.
    The present invention is aimed at solving the aforementioned needs, by means of a new method and recharging system for electric vehicles that allow to overcome the limitations of the state of the art.

    as well as other factors such as the state of the load terminals, state of the electricity grid, etc., providing an optimized load in yields and costs.
    Said object of the invention is realized, more specifically, by a recharging method of an electric vehicle, which comprises the use of a recharging system equipped with at least:
    - a charging point of the electric vehicle comprising a plug for connection to the electric vehicle, said charging point being equipped with hardware and / or software means for processing information associated with the charging, as well as for transmitting or receiving said information to / from a recharge management server; and with an interface for the introduction of recharging instructions to the system by a user; Y

    electrical energy in the recharge period defined by the user at the recharging point, through a query to the database or through a query to the source of information associated with the demand or the state of the power grid;
    e) the management server allocates the time sections, within the recharge period, that minimize the total price of electricity required for the recharge period according to the demand curve and / or tariffs based on, at least, the information obtained in step d) and the information obtained in step c);

    The calculation made in step e) refers to the assignment of one or more temporary sections of the battery recharge curve, within the time available for charging the battery, to one or more sections of the demand curve. tariffs within that time, so that the recharge curve is assigned to those sections of the demand / rates curve that have lower values (and therefore associated with lower prices). Said calculation, which comprises numerically analyzing the set of both curves and their ideal distribution over time, can be carried out by means of different numerical optimization methods, for example by means of an associated function said curves (typically, their product), so that it over time it is minimized, by means of stochastic simulations of the Monte Carlo type, or by means of genetic algorithms, as described, for example, in the references "Genetic Algorithms in Search, Optimization and Machine Learning" (DE Goldberg, 1989) or "Monte Carlo Statistical Methods" (CP Robert, 2004). This type of mathematical problems and their numerical solution is well known in the art and therefore does not form an essential part of the invention. If it is, however, the use for this purpose of the recharging system and its constituent elements as described in this document (recharge point, server, real-time data sources with the curves information, and process means configured for their treatment). Consequently, the solution to the technical problems mentioned in the previous section is obtained, in the present invention, thanks to the integration of different sources of information (refill curves and demand curves) in the same process and calculation system, of way that it allows to establish and plan the recharge cycles that most favor private users, in real time and adjusting to different modalities

    - A charging point (1) of the electric vehicle, preferably comprising a plug (2) for connecting to the electric vehicle. Said charging point (1) is additionally equipped with hardware and / or software means for processing information associated with the recharge, as well as for transmitting or receiving said information to / from a recharge management server (3), to the which is connected locally or remotely, for example through the Internet or a mobile network. The recharging point (1) also includes a user interface (4) for the introduction of instructions to the system, such as the duration of the recharging period, characteristics of the vehicle to be recharged, or recharging parameters for carrying out Different modalities of it.
    - A recharge management server (3), connected to the recharge point (1) and equipped with hardware and / or software means for recharge control performed by the

    plug (2), as well as for the planning and configuration of said recharge in time. The hardware / software means of the management server (3) are preferably configured to process data associated with the recharging of the vehicle, based on the information stored in at least one database (5) with information about the vehicles and / o of the users of the system and, at least, a source (6) of information associated with the demand and / or present or future tariffs associated with the supply of electrical energy. Said source of information may be, for example, information provided in real time by one or more operators or marketers of the electricity market.
    In this way, the management server (3) will be able to process, in real time and through its connection to the database (5), the local data associated with the vehicle to be loaded or its owner, such as the temporary availability slots of the vehicle for recharging, the model and characteristics of the vehicle to be recharged, the charging curves of its battery (i.e. the battery charge performance profile as a function of time), historical user recharge data, data local or ambient temperature, meteorological data, user habits, loss of recharge efficiency data due to temperature or climatic or seasonal effects, offline data related to the commercialization of electric energy, parameterization data of different recharge techniques , etc. Additionally, the management server (3) will also process the specific information associated with the demand of the electricity network in real time, thanks to its connection to the source (6) of information associated with the state of said network. Concrete examples of this information can be, for example, the daily rate curves as a function of time, provided by the operators or the commercialization of electric energy.
    Thanks to the processing of the information from the database (5) and the source (6) of information associated with the state of the electricity grid, the system of the invention can program the recharging procedure in the available period indicated by the user, so that such recharging is carried out in those time periods, within the aforementioned period, whose price is lower depending on the current rates, but also of the behavior of the battery or the vehicle according to its charging performance. Thus, the management server (3) will be able to calculate which are the ideal sections for carrying out the recharging of the vehicle, reducing its total costs and optimizing the performance of the battery to be recharged.

    Also, the option that the recharge management server (3) is remotely connected to the recharge point (1), allows to reduce the physical space that this point occupies, either in public places such as in the home or garage where the vehicle is parked. Said connection also allows the data used by the server (3) and, therefore, the system recharge modes to be updated at all times, both for tariff and technical or functional reasons for the user.
    Once the main elements of the system of the invention have been described, the main modes of its implemented recharge procedure are described, according to the embodiments shown in Figures 3 and 4. Said figures schematically represent the different stages of said procedure and its relationship with the charging point (1), the management server (3), the database (5) or the source of information (6) associated with the demand or the state of the electricity grid, for two preferred embodiments of the aforementioned procedure.
    In a first embodiment of the invention (Figure 3), the charging procedure starts at the charging point (1), where the user connects his vehicle to the plug (2) and gives charging instructions (7) to the system , by means of the user interface (4). These instructions will include the time period available for recharging (for example, from 8:00 p.m. to 8:00 a.m.) and, typically, a selected recharge mode, in case of counting a variety of them. By means of said start instructions (7), the recharge point (1) is connected to the recharge server (3) and transfers (8) to it the user's request.
    With said reception (8) of recharge instructions by the server (3), it connects to the database (5) and obtains (9) the data associated with the user, the vehicle and / or the selected charging mode , depending on the instructions generated by that user. Although in different embodiments of the invention the data used may be different, said data will always comprise, at least, information relating to the performance or charging behavior of the battery to be recharged and, more preferably, will comprise information related to the typical recharge curves of said battery. As mentioned, other usable data include, without limitation, one or more of the following: date, model and technical characteristics of the vehicle to be recharged, historical user recharge data, local or ambient temperature data and / or meteorological data.

    Once the data relating to the vehicle, the battery and / or the user are obtained (9), they are temporarily stored (9 ’) on the management server (3).
    Subsequently, the management server (3) will obtain (10, 10 ’) information about the demand and / or the rates associated with the electric power in the recharge period defined by the user at the charging point (1). These rates will be obtained, for example, through a query (10 ') to the database (5) in case they are not subject to market variations (for example, in those cases where the price is fixed or of "flat rate"), or by means of a query (10) to the source (6) of information associated with the demand or the state of the electricity grid (for example, when the price of electricity depends on the curves of Daily charging of the operator or the electric power retailer.
    Once obtained (10, 10 ') the data associated with the tariffs or the demand for electrical energy that will be applied to the user in the period enabled for recharging, the management server (3) will calculate (11) the sections, within said recharging period, which minimize the price of electricity based on, at least, the rates obtained in step (10, 10 ') and the time efficiency curves of the vehicle's battery to recharge. Also, in case the recharge period enabled is less than the time necessary to perform the full battery charge, the calculation (11) of the server (3) will optionally include the limited charge option according to the defined limits by the user through the interface (4), based on criteria related to load efficiency and / or applicable rates.
    Taking into account the calculation parameters described above, and using as a reference period the rates and performance curves of available batteries corresponding to the year 2015, it has been observed that the recharge procedure of the invention saves between 54% and 73%. % (depending on the recharging time periods studied and the efficiency curves used in the simulation) of the cost of energy with respect to the traditional recharge methods of the prior art. Said savings are produced through the optimized planning and allocation of battery recharge times to those available sections that have lower prices or demand within the corresponding curve. The reduction of the recharge cost associated with the present invention stems mainly from the difference between applying an optimized recharge, taking into account the battery recharge curves and the demand / price curves, and not applying any optimization in them, instead applying the direct loading method. On the other hand, although the application of some specific or other numerical methods to achieve

    Such optimization can additionally present small differences between them due to their particular efficiency, all of which are generally included in the range of improvement described compared to non-optimized methods.
    Optionally, other limits or recharging conditions may be, in different embodiments of the invention, taken into account in a general way in the procedure used, for example in cases where the user does not wish to recharge his vehicle above a certain rate. , or if you only want to recharge the vehicle battery to a certain level of charge. This last loading mode is illustrated as an example in Figure 4, where an additional calculation step (9 ’) of recharging sections is carried out depending on the setting of the top-up recharge value that the system will perform.
    After carrying out the calculation (11) of the appropriate sections within the recharge period enabled by the user, the management server (3) will send (12), finally, the programming of the procedure to be performed to the recharge point (1), which will be received and processed by the means of processing it. With this, the plug (2) of said charging point (1) will recharge the vehicle's battery in the terms calculated by the server (3).
    The described procedure can be combined, in different embodiments of the invention, with other charging modes, such as an optional fast charging mode, where the only criterion to be applied is the partial or total recharge of the battery, in the shortest possible time. In said embodiments, the selection of this recharge mode by the user, through the interface (4), will start the procedure in these terms, until the recharge level of the selected battery is reached.
    Additionally, in relation to the charging point (1) of the vehicle, it can be equipped with different elements or functionalities in the system of the invention, as shown, by way of example, in Figure 5. Said elements may comprise , for example:
    The plug (2) that connects to the vehicle can be any commercial plug, for example Schuko type, NEMA type, Type C, type D, Type E, SI-32, AS 3112, SEV 1011, Afsnit or other plugs used according to the industrial standards or norms of the country of application. It could also be changed to connectors of type SAE J1772, Mennekes, CSS, Scame or CHAdeMO, either directly or through adapters, to be able to
    17
    Connect the electric vehicle directly to the aforementioned charging point (1).
    The charging point (1) can also include a push button (13), a keyboard (13 ') or a touch screen (13' '), which will be used to select the charging mode to be used from 5 among different modes available, as well as for the introduction of the different parameters corresponding to the recharge period, maximum desired battery level, maximum rate or total cost to pay, etc. Also, the charging point (1) may include one or more visual, sound or haptic indicators (14), for example to indicate the selected charging mode, as well as its start or end, etc.
