Definitions
- the present invention relates to electrical energy storage devices by using high capacity capacitors, proposing a compact energy storage module for the power supply of traction equipment and auxiliary systems of railway vehicles such as trams, meters, or trains
- one of them consists of the tram power supply through a third rail located on the ground between the guide rails, which is segmented into small sections that are fed independently, so that they only have electric current the sections where the tram runs.
- These systems can be made with direct contact between the tram and the third rail, or without contact, where electricity does not pass through the tracks directly, but instead becomes converted through a magnetic field.
- the accumulators are constituted by several energy storage modules interconnected with each other for the supply of traction equipment and auxiliary systems of the tram, these modules are usually arranged on the roof of the tram and are partly recharged by the kinetic energy recovered from the braking, so it is not necessary to establish a continuous connection with the catenary.
- Conventional energy storage modules consist of multiple high capacity capacitors, known as supercapacitors, double layer capacitors, or ultracapacitors, which can be supported by A set of batteries.
- the capacitors are related to a power electronics and a control electronics that are arranged in direct contact, that is, the terminals of each capacitor of the module are connected directly with a connection plate that is immediately adjacent in its upper part. This arrangement is counterproductive, since high temperatures are reached in the capacitor terminals, which can affect the behavior of the control electronics.
- an energy storage module for the power supply of traction equipment and auxiliary systems of railway vehicles, which has a light and compact structure, and where the control electronics are isolated from the electronics of power
- the energy storage module for railway vehicles object of the invention is constituted by a plurality of capacitors interconnected in series, where each capacitor of the module has a pair of terminals that establish an electrical connection with a single connection plate common to all capacitors, and also establish a mechanical mooring with a support plate that is arranged between the terminals and the connection plate.
- the capacitor terminals are oversized so that they define a cooling channel between the support plate and the condensers, the connection plate being isolated from said cooling channel by the support plate.
- connection plate is isolated from the terminals of the condensers, there are no problems associated with the temperature or with the possible humidity that the cooling air carries and, also, when the terminals are oversized in length, the section of the cooling channel is increased and the cooling conditions of the terminals are improved.
- connection plate is isolated from the terminals of the condensers, there are no problems associated with the temperature or with the possible humidity that the cooling air carries and, also, when the terminals are oversized in length, the section of the cooling channel is increased and the cooling conditions of the terminals are improved.
- all the wiring is eliminated and with it its associated problems.
- the oversizing of the terminals is determined by a longitudinal elongation of the capacitor terminals themselves. According to another embodiment of the invention, the oversizing of the terminals is determined by means of a supplementary piece that is associated with each terminal of the capacitors.
- the cooling channel of the energy storage module of the invention has a section greater than 1.5 centimeters where a forced air circulation is performed, and where this section is of a size substantially equal to the size of the oversized terminals, which improves the cooling conditions of the capacitor terminals.
- this orificed sheet and the support plate have a support on its lateral sides, with tables that provide greater rigidity to the entire structural assembly, while also making lateral closure for the cooling channel, which improves the heat dissipation that is generated in the terminals of the condensers when cooling is carried out by forced air circulation.
- the assembly formed by the support plate, the laminated sheet and the stiffening boards, is a light and self-supporting structure, since it is made of composite resins, called as composite material, and also guarantees an appropriate electrical isolation of the module with other modules or nearby electrical equipment.
- All the capacitors of the same module are arranged connected in series, determining a single input and a single electrical output for the entire module and where the capacitors of the same row are connected in a straight line, while each row of capacitors is connected to the next one through a zig-zag-shaped connection.
- An energy storage module is thus obtained which, due to its constructive and functional characteristics, is very advantageous, acquiring its own life and preferential character for the application function to which it is intended in relation to the supply of electrical energy for railway vehicles, although This application is not limiting, and can be applied to other types of transport vehicles, such as hybrid buses, as well as other applications.
- Figure 1A shows a perspective view of a conventional energy storage module where the capacitor terminals are in direct contact with the connection plates.
- Figure IB shows an elevation view with respect to the previous figure, which shows the minimum section of the cooling channel.
- Figure 2A is an exploded perspective view of an energy storage module according to the object of the invention, wherein the terminals of the capacitors and the connection plate are separated by a support plate arranged between them.
- Figure 2B shows an elevation view with respect to the previous figure, where a cooling channel of greater section than the conventional one is defined.
- Figure 3 shows a sectional view of an exemplary embodiment of the oversizing of the terminals of the energy storage module according to the invention.
- Figure 4 shows a sectional view of another exemplary embodiment of the oversizing of the terminals of the energy storage module.
- Figure 5 shows the electrical interconnection established between the capacitors of the energy storage module.
- FIG. 6 shows the electrical interconnection of several energy storage modules.
- FIG. 1A A conventional energy storage module is shown in Figure 1A, which is formed by multiple interconnected capacitors (1).
- Each capacitor (1) of the module has two terminals (2), one for the positive terminal and one for the negative terminal.
- Above terminals (2) and directly connected to them are located connection plates (3) where the electrical signals of the module arrive, each capacitor (1) having a connection plate (3).
- the capacitors (1) of the same row are interconnected in series by means of plates (4) that connect the positive terminal (2) of a capacitor (1) with the negative terminal (2) of the next capacitor
- the cooling of the terminals (2) of the condensers (1) is carried out by the forced air circulation through a cooling channel (5) defined between the connection plates (3) and the upper surface of the condensers (1),
- This cooling channel (5) has a cross-section that coincides with the height of the terminals (2) (significantly lower than the terminals proposed by the invention, of the order of less than 1.5 centimeters), which may be insufficient for proper cooling of the terminals (2), in addition to presenting the problem that the control electronics come into direct contact with the forced air. (See figure IB).
- the energy storage module for railway vehicles object of the invention solves the above-mentioned problems, separating the control electronics from the power electronics and defining a cooling channel of sufficient section to perform a correct cooling of the terminals (2) of the capacitors (1).
- FIG. 2A An exploded perspective view of the energy storage module object of the invention is shown in Figure 2A, which consists of multiple high capacity capacitors (1) each having oversized terminals (2), which are the positive and negative capacitor terminals (1).
- the oversized terminals (2) are connected to each other by means of plates (4), placing above them a support plate (6), of a light material and with electrical insulation properties, which supports a single connection plate (7) common to all capacitors (1).
- the oversized terminals (2) fulfill a double function, on the one hand they make a mechanical tie with the support plate (6) that stiffens the entire module, and on the other hand they make an electrical connection with the connection plate (7), so that the terminals (2) that form the power electronics of the module, by means of the support plate (6) are isolated from the plate (7) of connections that form the module control electronics.
- the oversizing of the terminals (2) allows the definition of a cooling channel (8) with a sufficient section to efficiently dissipate the heat generated in the terminals (2). It is envisaged that an appropriate section for the cooling channel (8) is greater than 1.5 centimeters in height, approximately coinciding with the size of the oversized terminals (2).
- the cooling channel (8) that gives direct access to the terminals (2) is isolated from the connection plate (7), this channel (8) can be valid, both for forced air cooling and cooling by means of a fluid, where the cooling fluid circulates through the cooling channel (8) without coming into direct contact with the terminals (2) of the condensers (1).
- the support plate (6) and the laminated sheet (9) support their lateral sides in some stiffener boards (10), so that, on the one hand, they confer greater rigidity to the module, and on the other hand, they serve as a closure for the lateral sides of the channel (8), improving cooling when it operates by forced air circulation.
- FIG. 3 An exemplary preferred embodiment of the invention is shown in Figure 3, where the oversizing of the terminals (2) is carried out by means of a longitudinal elongation (2.1) of the terminals themselves (2) of the capacitors (1).
- a hole (12) is defined that crosses the connection plate (7), the support plate (6), the plate (4) and which enters the terminal ( 2), so that by inserting a conductive fastener, such as a screw, into said hole (12), the mechanical mooring and electrical connection are established.
- FIG 4 it can be seen how the oversizing of the terminals (2) is carried out by means of an extra part (11) that is associated with a conventional terminal (2).
- the hole (12) crosses the support plate (6), the plate (4) and enters the terminal (2), establishing the mechanical tie by inserting a fastening element, while the electrical connection with The terminals (2) are made, for example, by means of a screw that is inserted into a hole (13) that passes through the connection plate (7), the support plate (6), and the plate (4).
- Figure 5 shows the electrical interconnection of the energy storage module, in where all the capacitors (1) of the module are connected in series by means of plates (4) that connect the positive terminal (2) of each capacitor (1) with the negative terminal (2) of the next capacitor (1), of so that the capacitors (1) of the same row are connected in a straight line, and a row of capacitors (1) is connected with the following in the form of a zig-zag.
- This configuration allows a single electrical input (14) and a single electrical output (15) for the entire module, as well as this electrical interconnection of the capacitors (1) minimizes the voltage difference between adjacent capacitors (1).
- the maximum voltage difference between two capacitors (1) adjacent to the same module of 16 capacitors (1) will be 8 times the voltage between the bumpers (2) of a capacitor (1), that is to say the difference in voltage between the adjacent capacitors (1) located at the end of each row. This ensures minimum insulation distances, which contribute to the realization of a very compact storage module.
- This configuration of 16 capacitors is not limiting, and the energy storage module may have an alternative configuration in number of capacitors (1) and rows.
- the structure formed by the support plate (6), the orifice laminate (9) and the stiffening boards (10), is a lightweight and self-supporting structure made of composite resins (composite), which also guarantees an appropriate electrical isolation of the module with other modules or electrical equipment nearby.
- Figure 6 shows the electrical interconnection of several energy storage modules according to the invention, where to expand the capacity of electric energy accumulation of the module, simply connect the output (15) of a module with the input (14) of the following, which facilitates the scalability of the entire system.
- capacitors (1) have been represented with a circular configuration, although they could be supercapacitors, double layer capacitors, or ultracapacitors, of any type and known geometric configuration.
