Abstract

Battery Charger for Electric Vehicles. # Consists of a charger or milestone where you can recharge the battery of electric vehicles on a distributed basis. It allows by means of the use of connection boxes installed along the street and / or public or private parking, the recharging of the batteries of the vehicles parked at a certain distance from the charger itself. It allows, therefore, the purchase / sale of energy for recharging vehicle batteries.

Battery charger for electric vehicles.

The present invention aims at allowing the charging of batteries or any other energy storage model that vehicles may use at some time. Given the possibility of developing electric vehicles with battery operation, this invention allows the charging of these while they are parked. Background

The hitherto reduced or non-existent number of electric vehicles does not allow to indicate the current state of this field. The known or advanced so far is the possibility of charging the vehicle battery in a standard plug base.

The improvement introduced by the electric vehicle charger (CVE) is the possibility of charging the battery in the street.

For a long time it can be read in any newspaper or magazine that in the near future the cars will be electric and that their load will be carried out by plugging it into the mains as one more appliance. Given the conception of most cities, with housing blocks of various heights, it is not possible to charge your vehicle energy from your own home. What will generate a new market; the purchase of energy for charging the vehicle on the street or parking. This would also be possible in all types of parking lots in supermarkets, shopping centers, stations, airports, etc.

Document IO137344 describes an element that allows the loading of a single vehicle parked next to the charger. This charger allows to load several nearby vehicles (at least six) and also allows the loading of vehicles parked along the street or parking by means of peripheral connection boxes, remote from the charger. Description of the invention

The charger is an element for installation on roads or areas of access or passage of the public. It is a prismatic shaped element (Figure 1) with a recess in the section that will be mounted on the loader drive controls (1) (alphanumeric keypad, push buttons, etc.). It has several watertight doors, automatic opening, (3) at different heights behind which are the plug bases for nearby charging. It also has a larger section door for registration and repair of interior elements (2).

We also describe the boxes for connection of vehicles parked on the street. These are boxes arranged replacing some of the street curbs (Figure 2, 2.1). They are defined with a slit in its longitudinal axis to allow the vehicle connector to be protected from bumps, etc. (Figure 2, 2.1) These boxes, sealed, have two connectors that allow charging. They are installed by replacing a conventional curb every several meters along the sidewalk. This allows reducing the length of the charging cable from the vehicle.

They will be connected with a power and control line, laid under underground pipes, to the charger where you can select, by means of an alphanumeric keypad, the box and the socket for charging the vehicle. (Figure 3).

They will be connected with a power and control line, laid under underground pipes, to the charger where it is set 4).

The charger allows the remote control of the cargo boxes to be installed in public car parks. In the access of the car park or plant, the charger can be installed and arranged in a roof, walls or floor (fi g. 4, 5) load boxes (such as those already indicated or different) will be installed. You can select in the charger the box to be activated for charging the vehicle, once removed it pays the amount of energy consumed. (Figure fi g. 2).

The charger allows the control and control of the energy to be supplied by the boxes or by itself. Depending on the total power to be distributed, according to the length of the street or the parking spaces that depend on a single charger, it will function as a control of one or several attached electrical panels or will function as a power distributor. Brief description of the drawings

For a correct understanding of what has been described, some drawings / diagrams are shown where the charger and the connection boxes are represented for electric charging of the vehicles.

Figure 1 represents the elevations of the loader. In them we can appreciate the keyboard and the display (a) and the different doors for access to the sockets

(c) and its components (b). Figures 2 and

2.1 show us the two types of battery charging boxes. They have similar shape and dimensions to those of a conventional curb. The model in Figure 2 is a box of insulating or metallic material embedded in a concrete or similar housing or body (with the sidewalk curb) with two plug bases (d). It has a small slit (f) to connect, to shock protection, the connector of the vehicle to be loaded (e). The model described here would be, once installed, at a level with the sidewalk. On the other hand, the model in Figure 2.1 is described, which is with similar characteristics, a variant of the previous one in which the box rises a few centimeters above the sidewalk

(g)

so that the power outlets are a little high with respect to the road.

Figure 3 represents a diagram of the interconnection between the elements described. From a charger

(h)

command and control lines tend to the different cargo boxes or vehicle connections (i).

Figures 4,5 and 6 represent different ways of installing or placing the cargo boxes depending on the place in question:

The fi g. 4 shows an example of installation for loading vehicles parked on the street (k), where the junction boxes are integrated in the sidewalk

(i)

The fi g. 5 represents a covered or underground parking area in which the connection or load box can be mounted on the roof (i), in this case the charger can be placed at the entrance of the enclosure.

The fi g. 6 shows an example of outdoor parking typical of shopping centers, airports, etc. where the cargo boxes (i) can be installed as indicated. Embodiment of the invention

The charger (CVE) is a prismatic element made of metallic material with anticorrosive treatment. It has several die openings in the sheet (Fig. 1), where the sockets for direct connection, the door for access to the interior and the door are located.

keyboard and display module. Inside it has several blocks or systems to be defined:

Automation of electrical protection and measurement for each of the power supply lines to the cargo boxes.

Auxiliary equipment for conversion of signals received from the measuring equipment with the customer and the maintainer.

Interconnection system via Ethernet or similar with central management and maintenance of the equipment.

The connection or load boxes are made of metallic or plastic material of high hardness. They are mounted inside a “mold” of concrete or similar “C” shaped material that hugs the cargo box; so that it simulates a curb. It is intended not to flood the sidewalks with elements that may be visually annoying.

They are prismatic in shape with a slit in their longitudinal axis (Figures 2, 2.1.). It will be housed two plug bases for charging vehicles.

It is understood as evident, as described in its embodiment, the industrial application.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement  Lack of Novelty Claim 1 Document D01 is established as the closest to the State of the Art. Said document D01 refers to "a charging system for an electric vehicle" and contains: -connection boxes (230) located along the sidewalk that allows charging a battery (302) (see summary; figure 2). The object of the invention set forth in claim 1 derives directly and without any ambiguity from document D01. Therefore, claim 1 lacks Novelty (Art 6.1 LP). Claim 2 The existence of an alphanumeric keyboard already appears in document D02 (see column 3, line 65-column 4, line 14; figure 4). Accordingly, claim 2 is not new (Art 6.1 LP). Claim 4 A central manager is already in document D01 (see summary; figure 1). Consequently, claim 4 lacks Novelty (Art 6.1 LP). Claim 5 Several connection boxes are already shown in document D01 (see figure 2). Therefore, claim 5 lacks Novelty (Art 6.1 LP). Claim 6 The features of claim 6 are contained in document D01 (see summary; figure 2). Accordingly, claim 6 lacks Novelty (Art 6.1 LP). Lack of Inventive Activity Claim 3 The use of a feeder for the measurement and collection of electrical energy consumed is a well-known technique and therefore obvious to a person skilled in the art. Consequently, claim 3 lacks Inventive Activity (Art 8 LP). State of the Art Report Page 4/4
