Description

[0001] RECHARGING SYSTEM OF A BATTERY AND RELATED RECHARGING METHOD

[0002] FIELD OF THE INVENTION

[0003] The present invention relates to a recharging system of a battery and to the related recharging method.

[0004] DESCRIPTION OF THE PRIOR ART

[0005] Nowadays, in order to use alternative technologies to reduce or eliminate the use of fossil fuels and to reduce polluting emissions, there is a move towards greater use of electrically powered devices, vehicles or machinery, having a battery for storing the electrical energy necessary for the respective electric power supply.

[0006] For example, nowadays, the use of hybrid or electric vehicles is increasingly widespread.

[0007] Generally, hybrid vehicles combine a traditional internal combustion engine with at least one electrically powered engine. These vehicles can operate both with the petrol / diesel engine and with the electrically powered engine, depending on the driving conditions.

[0008] Electric vehicles, on the other hand, are powered exclusively by electrically powered engines.

[0009] Both types of vehicles, therefore, are powered by rechargeable electric batteries, which are recharged, in the first case, during driving, for example through the recovery of braking energy; while, in the second case, from a domestic power socket or from public electric recharging stations.

[0010] In both the above-mentioned cases, such batteries are lithium batteries. Lithium batteries are known for their high energy density, which allows them to store a significant amount of energy in a relatively small volume.

[0011] The recharging speed depends on the power of the charger and on the capacity of the battery. Fast charging stations are often used to significantly reduce recharging times.

[0012] In this regard, in recent years there has been a continuous evolution of battery technology and related recharging systems, in order to identify alternative recharging modes to those described above.

[0013] SUMMARY OF THE INVENTION

[0014] In light of the above, the object of the present invention consists in identifying a recharging system of a battery alternative to those described above.

[0015] A further object of the present invention is to provide a recharging system of a battery alternative so as to ensure the use of energy sources such as not to produce harmful emissions during the recharging process and, in this way, contribute to reducing dependence on fossil fuels, such as oil or coal, the environmental impact and to combat climate change.

[0016] The present invention provides an advantageous choice both from the environmental and economic point of view, as it promotes sustainability and favors long-term energy autonomy.

[0017] The above-mentioned objects are achieved by means of a recharging system of a battery according to claim 1 and a recharging method of a battery according to claim 12.

[0018] Advantageously, the recharging system of a battery of the present invention allows to convert into electrical energy, through the plurality of thermoelectric modules, the heat generated during the adsorption phase of the liquid by the zeolite. Such electrical energy will be fed to the battery in order to be stored and used according to the needs or used to electrically power the components of the system itself.

[0019] Moreover, the heating means ensure that, following the adsorption phase, the desorption phase of the zeolite takes place, in order to cyclically ensure the release of heat by the zeolite itself.

[0030] With reference to the attached drawing sheets, a recharging system (1) of a battery (2) is generally indicated by the reference numeral (1), comprising: a reservoir (3) containing a liquid selected from demineralized water, distilled water, water, aqueous solution containing a water-miscible compound or a mixture of demineralized water or distilled water or water and silica powder particulates; pumping means (4) which are arranged and configured to pump the liquid from the reservoir (3); a chamber (5) containing zeolite (Z) in solid form and in fragments, said chamber (5) having at least one side wall (5a) and a bottom wall (5b); a plurality of nozzles (6) which are arranged inside the chamber (5) and which are configured to be activated to dispense the liquid into the chamber (5) so as to distribute it among the fragments of said zeolite (Z), so that the latter absorbs the liquid to release heat; a plurality of thermoelectric modules (7) comprising a first side (7a) and a second side (7b), which is arranged opposite and parallel to the first side (7a), which are arranged to laterally surround the chamber (5) so that the first side (7a) of each thermoelectric module (7) contacts at least one side wall (5a) or the bottom wall (5b) to absorb the heat released by said zeolite (Z) and convert it into electrical energy; an insulating material layer (8) which is arranged to laterally surround the chamber (5) so as to contact at least one side wall (5a) and the bottom wall (5b) and leave the second side (7b) of each thermoelectric module (7) exposed to the outside; a battery (2); heating means

[0031] (9) which are carried by at least one side wall (5a) or the bottom wall (5b) and configured to be activated, once the nozzles of the plurality of nozzles (6) are deactivated, to generate heat in the chamber (5) in such a way that it distributes among the fragments of said zeolite (Z) so that the absorbed liquid evaporates from the latter (see figures 1-4).

[0032] Furthermore, the recharging system (1) comprises: a hydraulic feed circuit

[0033] (10) which extends to connect the reservoir (3), the pumping means (4) and the chamber (5) so that, when the pumping means (4) pump the liquid from the chamber (5), the latter is fed to the plurality of nozzles (6) which, once activated, distribute it among the fragments of zeolite (Z); an electrical power supply circuit (11) which extends to connect the plurality of thermoelectric modules (7) and the battery (2) so that the electrical energy produced, as a result of the conversion of the heat produced by the zeolite (Z), is fed to the battery (2) so as to recharge it (see figures 1-4).

[0034] By liquid is meant in the liquid state at room temperature.

[0035] By water it is meant water coming from the water supply network and, therefore, containing solutes.

[0036] Preferably, the reservoir (3) contains a liquid selected from distilled water, water and aqueous solution.

[0037] The recharging system (1) of a battery (2) can be a recharging system (1) of a lithium battery.

[0038] By battery (2) it is meant a rechargeable battery.

[0039] By way of example, by battery (2) it can be meant the rechargeable battery of a renewable energy source production device, for example the rechargeable battery of a photovoltaic panel.

[0040] The reservoir (3) can comprise an opening (12) (see figures 1-4).

[0041] The reservoir (3) can be filled with the liquid by an operator manually. Alternatively, the reservoir (3) can comprise a duct (13) connected to the opening (12) and to a liquid reserve (not shown) for the automatic filling of the reservoir (3) itself.

[0042] Furthermore, the reservoir (3) can comprise a level sensor (14) and a vent valve (15) (see figures 1-4).

[0043] Both in the case of manual and automatic filling, during filling, critical situations can occur in which, due to operator error or automatic actuation error, the reservoir (3) is overfilled.

[0044] Advantageously, the level sensor (14) and the vent valve (15) ensure the achievement of the correct liquid level inside the reservoir (3).

[0045] The aqueous solvent can comprise at least 99% of water.

[0046] Preferably, the aqueous solvent comprises at least 80% of water.

[0047] Preferably, the reservoir (3) contains distilled water.

[0048] Advantageously, the use of distilled water limits the formation of limescale along the hydraulic feed circuit (10) and at the components of the recharging system (1) itself.

[0049] By way of example, the pumping means (4) can be configured to operate with a working pressure between 4-8 bar.

[0050] The pumping means (4) can be arranged interposed between the reservoir (3) and the chamber (5) containing zeolite (Z).

[0051] The zeolite (Z) can be in fragments having a diameter between 1 mm - 5 cm.

[0052] By way of example, the thermoelectric modules (7) can be Peltier modules.

[0053] Furthermore, also by way of example, the insulating material layer (8) can be a layer of bio-adhesive made of glass wool. The at least one side wall (5a) and the bottom wall (5b) can be made of steel.

[0054] In figures 3-4, the insulating material layer (8) is shown partially covering the at least one side wall (5a).

[0055] It is easily deducible by a person skilled in the art that the optimal working condition of the recharging system (1) provides that the insulating material layer (8) completely covers the chamber (5), that is, it covers all the outer surfaces of the chamber (5).

[0056] Preferably, and according to a first embodiment, the recharging system (1) of a battery (2) comprises a processing unit (16) configured to time-operate the pumping means (4) so as to alternate between time intervals wherein the pumping means (4) are operational and time intervals wherein the pumping means (4) are non-operational (see figures 1 and 3).

[0057] Advantageously, the processing unit (16) is configured to manage the activation / deactivation time of the pumping means (4) in order to draw and introduce the liquid from the reservoir (3) to the chamber (5) in a given time interval, as a function of the preset quantity of liquid in a working cycle.

[0058] The processing unit (16) can be configured to operate the pumping means (4) and the nozzles of the plurality of nozzles (6).

[0059] The recharging system (1) can comprise at least one safety valve (17) which is arranged at the chamber (5) and which is configured to send an alarm signal to the processing unit (16), if within the chamber (5) a temperature or pressure value higher than a threshold value is reached (see figures 1-4).

[0060] Furthermore, the recharging system (1) can comprise a second level sensor (18) for liquid for monitoring the liquid level in the chamber (5) (see figures 1 and 3).

[0061] In a malfunction condition of the pumping means (4) and, therefore, a failure to interrupt the introduction of liquid towards the nozzles, the second level sensor (18), detecting a liquid level higher than a threshold value, sends an alarm signal to the processing unit (16).

[0062] Furthermore, the recharging system (1) can comprise a pressure gauge which is arranged inside the chamber (5) and a second vent valve (19) which is configured to expel excess water or air inside the chamber (5), as a function of the value detected by the second level sensor (18) of liquid or by the pressure gauge.

[0063] The recharging system (1) comprises a temperature sensor (20) which is arranged inside the chamber (5) and a switch (21), which are connected to each other and which are arranged along the electrical power supply circuit (11) (see figures 1 and 3).

[0064] If the temperature sensor (20) detects a temperature value inside the chamber (5) higher than a threshold value, it will send a signal to the processing unit (16) to operate the switch (21) in closing, so that there is no electrical power supply to the pumping means (4) and a non-operational condition of the pumping means (4) is ensured.

[0065] Instead, if the temperature sensor (20) detects a temperature value inside the chamber (5) lower than a threshold value, the processing unit (16) will leave the switch (21) in opening, so that there is electrical power supply to the pumping means (4) and the operational condition of the pumping means (4) is ensured.

[0066] Alternatively, and according to a second embodiment, the recharging system (1) of a battery (2) can comprise a volumetric metering unit (22) which is disposed upstream of the plurality of nozzles (6), along the hydraulic feed circuit (10), and a processing unit (16) configured to regulate, within a predetermined time interval, the dosage of liquid to each nozzle of the plurality of nozzles (6) (see figures 2 and 4).

[0067] Advantageously, the processing unit (16) is configured to manage the quantity of liquid to be introduced into the chamber (5) through the pumping means (4).

[0068] In this case, the volumetric metering unit (22) is arranged interposed between the pumping means (4) and the chamber (5) (see figures 2 and 4).

[0069] The processing unit (16) introduced for the first embodiment and for the second embodiment can be considered analogous. Preferably, the recharging system (1) of a battery (2) comprises a regulating device (23) of the pressure of the liquid pumped from the reservoir (3) to the chamber (5), which is arranged interposed between the pumping means (4) and the chamber (5) along the hydraulic feed circuit (10) (see figures 1-4).

[0070] Advantageously, the regulating device (23) of the pressure ensures the optimal working condition of the nozzles of the plurality of nozzles (6), so as to overcome the difference existing between the pressure of the liquid coming from the pumping means (4) and the working pressure of the nozzles themselves, thus avoiding a non-efficient working condition.

[0071] Additionally, the recharging system (1) can comprise a two-way solenoid valve (24) which is interposed between the pumping means (4) and the chamber (5), along the hydraulic feed circuit (10), and which is configured to interrupt the introduction of the liquid into the chamber (5) (see figures 1-4).

[0072] Furthermore, the recharging system (1) can comprise a check valve (25) which is arranged interposed between the two-way solenoid valve (24) and the chamber (5), along the hydraulic feed circuit (10) (see figures 1-4).

[0073] The processing unit (16) is configured to operate the check valve (25) and the two-way solenoid valve (24).

[0074] The recharging system (1) can comprise a first recirculation duct (26) which extends from the regulating device (23) of the pressure and reaches the reservoir (3) for the recirculation of the liquid (see figure 3A).

[0075] The regulating device (23) of the pressure can conform an expansion valve.

[0076] The hydraulic feed circuit (10) can comprise a first branch (10a) which puts in communication the regulating device (23) of the pressure and the reservoir (3) to introduce, again into the reservoir (3), the liquid that exits from the regulating device (23) of the pressure.

[0077] The processing unit (16) can be configured to receive the value detected by the level sensor (14) and operate the vent valve (15), depending on the working conditions.

[0078] Additionally, the processing unit (16) can be configured to operate the regulating device (23) of the pressure, depending on the working conditions.

[0079] Preferably, the chamber (5) comprises: a first opening (27) which is arranged to put the inside of the chamber (5) into communication with the outside; at least one perforated plate (28) which is arranged at the first opening (27) and is dimensioned to prevent the exit of said zeolite (Z) from the chamber (5); a control valve (29) which is arranged at the first opening (27) and which is configured to assume an opening configuration in which it allows the liquid to exit the chamber (5) and a closing configuration in which it prevents the liquid from exiting the chamber (5) (see figures 5-7).

[0080] Advantageously, if the need arises to interrupt the adsorption phase of the zeolite (Z), the quantity of liquid present in the chamber (5) may be dispensed outward through the first opening (27).

[0081] The control valve (29) can form a solenoid valve (see figures 1-4).

[0082] Additionally, the perforated plate (28) can have holes dimensioned to prevent the passage of the fragments of zeolite (Z).

[0083] In this way, when the control valve (29) assumes the opening configuration, thanks to the presence of the perforated plate (28), the undesired passage of the fragments of zeolite (Z) into the liquid exiting from the chamber (5) through the first opening (27) is prevented.

[0084] In figure 7 the perforated plate (28) is shown forming a box and the control valve (29).

[0085] The recharging system (1) can comprise a second recirculation duct (46) which extends from the control valve (29) and reaches the reservoir (3) for the recirculation of the liquid (see figure 3A).

[0086] The bottom wall (5b) can comprise a first portion (30) and a second portion (31) which is opposite to the first portion (30); the first portion (30) and the second portion (31) have an inclined orientation towards the first opening (27) so that the excess liquid inside the chamber (5) is conveyed, from the first portion (30) and the second portion (31), towards the first opening (27) (see figure 6). The bottom wall (5b) can comprise a third portion (32) and a fourth portion

[0087] (33), which is opposite to the third portion (32) (see figure 6).

[0088] The third portion (32) and the fourth portion (33) can be arranged to join the first portion (30) and the second portion (31) to each other (see figure 6).

[0089] The third portion (32) and the fourth portion (33) can have an inclined orientation towards the first opening (27) so that the excess liquid inside the chamber (5) is conveyed from the first portion (30), the second portion (31), the third portion (32) and the fourth portion (33) towards the first opening (27) (see figure 6).

[0090] The electrical energy produced by the plurality of thermoelectric modules (7) in one operating cycle is such as to support, at least partially, the energy consumption of the components of the recharging system (1) of a battery (2) itself.

[0091] Moreover, in a first operating condition, an electric energy supply source is necessary in order to initialize the operating phases of one operating cycle of the recharging system (1); whereas, the electrical energy stored in a previous operating cycle electrically powers the operating phases of a subsequent operating cycle.

[0092] Therefore, the battery (2) must be at least partially charged to initially power each operating cycle of the recharging system (1).

[0093] In fact, the recharging system (1) of a battery (2) can comprise a connector

[0094] (34) for recharging the battery (2) itself (see figures 1-4).

[0095] In figures 1-4, the chamber (5) is shown in section so as to make visible the nozzles of the plurality of nozzles (6) and the overlapping between the at least one side wall (5a), the thermoelectric modules of the plurality of thermoelectric modules (7) and the insulating material layer (8), and between the bottom wall (5b), the thermoelectric modules of the plurality of thermoelectric modules (7) and the insulating material layer (8).

[0096] Furthermore, in figure 5 the second side (7b) of each thermoelectric module (7) is clearly visible, which is exposed to the outside and which is not covered by the insulating material layer (8).

[0097] The heating means (9) can comprise at least one resistor (35) which is arranged inside the chamber (5) and which is at least partially covered by the zeolite (Z) in fragments (see figure 8).

[0098] The at least one resistor (35) can determine an internal temperature of the chamber (5) comprised between 200°-250°C.

[0099] In figure 8 such embodiment is illustrated.

[0100] Moreover, in figure 8 a control unit (36) and a power converter (37) are shown which are connected to the at least one resistor (35).

[0101] The power converter (37) can be electrically powered by one or more photovoltaic panels (100) (see figure 8).

[0102] Furthermore, in figure 8 some thermoelectric modules (7) have been removed to show, in dashed lines, the zeolite (Z) in fragments and the at least one resistor (35) inside the chamber (5).

[0103] Alternatively, and with reference to figure 9, the heating means (9) comprise an induction heating unit (38) arranged to heat at least one side wall (5a) or the bottom wall (5b) of the chamber (5), at the respective outer surface.

[0104] The induction heating unit (38) can be electrically powered by one or more photovoltaic panels (101) (see figure 9).

[0105] Still with reference to figure 9, the respective coil of the induction heating unit (38) is shown arranged to surround at least one side wall (5a) of the chamber (5).

[0106] Moreover, in figure 9 a control unit (36) is shown which is connected to the induction heating unit (38).

[0107] By way of example, the heating means (9) can form adhesive heating mats (not shown) which can be arranged along at least one side wall (5a) or the bottom wall (5b).

[0108] With particular reference to figures 10 and 11 , the heating means (9) can comprise a hot air inlet mouth (90) which is arranged on at least one side wall (5a) or the bottom wall (5b) to introduce hot air into the chamber (5).

[0109] According to this embodiment, with reference to figure 10, the heating means (9) can form a convector heater (91) which is in connection, with the respective connecting pipe (92), with the hot air inlet mouth (90).

[0110] Alternatively, with reference to figure 11, the heating means (9) can form vacuum solar collectors (93) which are in connection, with the respective connecting pipe (94), with the hot air inlet mouth (90).

[0111] Preferably, the heating means (9) comprise an electronic device that generates microwaves (95) and a cathode (96) for the release of electrons into the chamber (5) (see figure 12).

[0112] The electronic device that generates microwaves (95) can form a magnetron.

[0113] Moreover, the cathode (96) can be a heated cathode for the release of electrons.

[0114] In other words, the microwaves generated by the electronic device that generates microwaves (95) cause the vibration of the molecules of the liquid absorbed by the zeolite (Z), so as to generate heat by friction and heat the zeolite (Z).

[0115] By microwaves it is meant high-frequency electromagnetic waves.

[0116] With reference to the first, second, third and fourth embodiment of the heating means (9), the at least one side wall (5a) and the bottom wall (5b) can be made of metal.

[0117] With particular reference to the fifth embodiment of the heating means (9), if the at least one side wall (5a) and the bottom wall (5b) are made of metal, they must be coated with a material made of polytetrafluoroethylene (PTFE), for example.

[0118] Alternatively, still with reference to the fifth embodiment of the heating means (9), the at least one side wall (5a) and the bottom wall (5b) can be made of ceramic material. A recharging method of a battery (2) is disclosed below, which is also the object of the present invention.

[0119] Such method can be implemented by the recharging system (1) described above.

[0120] The recharging method of a battery (2) can comprise the steps of: arranging a reservoir (3); pumping into the reservoir (3) a liquid selected from demineralized water, distilled water, water, and aqueous solution containing a water-miscible compound or a mixture of: demineralized water or distilled water or water and silica powder particulates; arranging a chamber (5) containing zeolite (Z) in solid form and in fragments, said chamber (5) having at least one side wall (5a) and a bottom wall (5b); dispensing the liquid into the chamber (5) so as to distribute it among the fragments of said zeolite (Z), so that the latter absorbs the liquid to release heat; arranging a plurality of thermoelectric modules (7), comprising a first side (7a) and a second side (7b), which is arranged opposite and parallel to the first side (7a), laterally to the chamber (5) so that the first side (7a) of each thermoelectric module (7) contacts at least one side wall (5a) or the bottom wall (5b) to absorb the heat released by said zeolite (Z) and convert it into electrical energy; thermally insulating the chamber (5) leaving the second side (7b) of each thermoelectric module exposed to the outside; generating heat in the chamber (5), once the step of dispensing the liquid into the chamber (5) is completed, in such a way that the heat is distributed among the fragments of said zeolite (Z) so that the absorbed liquid evaporates from the latter; electrically connecting, by means of an electrical power supply circuit (11), the plurality of thermoelectric modules (7) and a battery (2) so that the electrical energy produced, as a result of the conversion of the heat produced by the zeolite (Z), is fed to the battery (2) so as to recharge it.
